I reflect on the complexities of ME/CFS, noting that millions have sacrificed their cognition due to the effects of the Spike protein from both SARS-CoV-2 infections and vaccines. The persistence of Spike leads to serious health issues, including cognitive impairments akin to those seen in HIV-related conditions. Studies indicate a significant overlap between cognitive symptoms in COVID-19 and HIV-associated neurocognitive disorders. As we explore treatment options, understanding the long-term implications of Spike and its cumulative effects remains crucial for both adults and children.

We must accept "Solving ME/CFS" required sacrificing the cognition of millions, including those robbed of their cognition and autonomy after allowing conversion from Asymptomatic Neurocognitive Impairment.

5 points fondamentaux que vous devez savoir sur la Spike du SARS-CoV-2 (🦠 et 💉) De retour après plusieurs jours de pause... et ça fait du bien ! Je lance ce thread en 5 points. 1. La Spike est produite aussi bien lors d'une infection par le SARS-CoV-2 que par les injections anti-covid. Si on a des données solides pour les covid-longs, on en a beaucoup moins pour les PVS (Syndromes Post-Vaccination). Les études sont disparates et il n'y a aucune étude comparative. Du moins, pas à ma connaissance. Ce que je sais, c'est que la Spike est potentiellement la responsable de ces PVS. Les injections anti-covid font produire de la Spike... mais en quelle quantité ? Et quid de la biodistribution - autrement dit, on n'a toujours aucune idée de la production de Spike dans les tissus. 2. La Spike enclenche divers problèmes : les Spikeopathies. De fait toxique, elle persiste dans les organismes pendant des mois... voir des ANNÉES. Et il y a donc un effet cumulatif. Du fait de sa persistance, la Spike des injections anti-covid vient se rajouter à la Spike des infections covid... créant un vrai problème de dose cumulative. Et une synergie "virus + injections anti-covid". Car oui, les injections anti-covid ne protègent pas, ni des infections ni des formes graves. Mais rajoutent de la Spike sur de la Spike. 3. La Spike est dégénérative. Elle est amyloides, amyloidogène et peut utiliser les fibres amyloides pour permettre au virus de coloniser l'organisme. On aura des pathologies comme Alzheimer, Parkinson, des démences et diverses des amyloses comme les fibrinaloides... (Creutzfeld Jakob) (Amyloses) 4. La Spike est toxique pour le système immunitaire. - du fait de sa persistance, elle peut épuiser les lymphocytes T. Là aussi, l'épuisement des lymphocytes T est un marqueur aussi bien des covid-longs que des PVS. Mais, du coup, qui dit "système immunitaire épuisé" dit "système immunitaire hors-service". C'est devenu une passoire pour les pathogènes... surtout le SARS-CoV-2. 5. La Spike entraîne des perturbations métaboliques... C'est en lien avec ses propriétés cancérigènes mais aussi, son impact sur l'ensemble de l'organisme. Fatigue chronique et perte du tonus musculaire sont deux grandes caractéristiques. Être spiké, c'est passer dans une essoreuse... avec des impacts de fond. Beaucoup de questions sont encore en suspens... comme les effets épigénétiques, les impacts sur les futures générations et la fertilité. Mais ces 5 points là sont déjà beaucoup d'arguments à opposer aux injections anti-covid et à demander aux soignants de... nous soigner. Le potentiel bacteriophage du SARS-CoV-2 est un argument clé en faveur des antibiotiques. Limiter la propagation du virus dans l'organisme et donc la production de Spike est important ! Fondamental au regard de la persistance de la protéine Spike et des Spikeopathies, des propriétés amyloides (et donc dégénératives), immunotoxiques et des impacts métaboliques. Cela vaut pour les adultes mais aussi les enfants. Merci beaucoup de m'avoir lue. 💯💯💯

Bien... petite réaction à chaud sur cette publication de Nakao Ora et al. 2025. Persistance de la Spike dans les syndromes post-vaccinaux (PVS) Persistance de la Spike après infection par le SARS-CoV-2 et persistance du virus.

Video Transcript AI Summary
Cette vidéo résume: selon Nakaoota et al. (3 avril 2025), « l’expression de la protéine Spike chez 43.8 pour 100 des personnes vaccinées anti Covid » persiste « au niveau des artères coronaires » jusqu’à 17 mois après l’injection, avec « l’ARN messager, du vaccin, mais également du virus » détecté. Il y a « persistance de la protéine Spike » et « persistance du SARS-CoV-2 » possiblement malgré les traitements précoces. L’auteure mentionne aussi « Crüssfeld Jacob, 14 mois après infection » et une étude sur des « AVC 17 mois après injections ». L’interaction de la nucléocapside (protéine N) avec TRIM28 pourrait retarder la réponse immunitaire innée, renforçant la tolérance immunitaire via TLR2/RAGE et IgG4. Conséquences: infection potentiellement asymptomatique et dégâts cumulatifs; Spike persistante pourrait entraîner « spike viral plus spike vaccinal ». Des spycopathies neurologiques sont évoquées; dépistage de Spike et traque du virus recommandés; traitements personnalisés et soutien par curcumine, quercétine, vitamine D; approche individuelle. This video summarizes: according to Nakaoota et al. (April 3, 2025), « the expression of the spike protein in 43.8 per 100 of vaccinated people » persists « at the level of the coronary arteries » for up to 17 months after injection, with « mRNA from the vaccine, but also the virus » detected. There is « persistence of the Spike protein » and « persistence of SARS-CoV-2 » possibly despite early treatments. The author also cites « Crüssfeld Jacob, 14 months after infection » and a study on « strokes 17 months after injections ». The interaction of the nucleocapsid protein (N) with TRIM28 could delay the innate antiviral response, reinforcing immune tolerance via TLR2/RAGE and IgG4. Consequences: potentially asymptomatic infection and cumulative damage; persistent Spike could lead to « spike viral plus spike vaccinal ». Neurological spycopathies are discussed; diagnostics to detect Spike and tracking the virus are recommended; therapies to block/remove Spike and personalized approaches, with supports like curcumin, quercetin, vitamin D.

Speaker 0: Bonjour à tous et à tous. Je suis Annelies Bocket, je suis docteure en biologie santé et spécialisée en immunologie, et je n'ai absolument aucun conflit d'intérêt, que ce soit d'ordre privé, personnel, financier, peu importe. Je n'ai pas de conflit d'intérêt. Je me permets de faire cette petite vidéo suite à la parution d'un nouvel article de Nakaoota et al en date du 3 avril 2025 qui démontre l'expression de la protéine Spike chez 43.8 pour 100 des personnes vaccinées anti Covid avec une persistance de cette protéine Spike au niveau des artères coronaires et ce jusqu'à 17 mois après l'injection. On a également détecté de l'ARN messager, du vaccin, mais également du virus au niveau donc de ces artères coronaires. Donc il y a bien une persistance de la protéine Spike. Je ne reviendrai pas sur l'étude de Yel Lissen qui a démontré la persistance de cette protéine Spike plus de 700 jours après les injections anti Covid. Mais il y a aussi une persistance du SARS-CoV 2. Et ceci peut-être en dépit des traitements précoces. J'expliquerai juste après pourquoi. Il y a une persistance de la spi vaccinale, donc comme je viens de vous le décrire, mais également possiblement de l'ARN messager modifié avec une production donc de cette spike des mois après les injections anti covid. Aujourd'hui, a quand même quelques publications assez alarmantes. Dès Crüssfeld Jacob, 14 mois après infection par le SARS-CoV 2. Là, ici, sur ce nouvel, sur cette nouvelle publication des AVC, 17 mois après potentiellement injections plus infections. Et donc je vais vous expliquer pourquoi le SARS-CoV 2 persiste et quelles sont mes dernières recherches. Il faut savoir que la protéine mucocapside du SARS-CoV-2, donc la protéine N du SARS-CoV-2 interagit avec TRIM vingt-huit. C'est quoi TRIM vingt-huit C'est un facteur impliqué dans une grande variété de processus cellulaires comme le matière des cellules souches, la réparation de l'ADN, l'apoptose, l'autophagie, et j'en passe. La perte de Trim 28 lors du développement de l'embryon chez la souris est l'étale. Et Trim 28 peut être impliqué dans de nombreux cancers, globalement. Le problème, c'est que TRIM 28 est aussi impliqué dans l'homéostasie du système immunitaire et dans son activation. Donc, si TRIM 28 est impactée, alors la réponse immunitaire innée en réponse à l'infection par le SARS -CoV 2 est aussi impliquée. Notamment, il va y avoir un délai, un retard dans le lancement de la réponse immunitaire antivirale. Il se peut alors que la réponse immunitaire lors d'une infection par le SARS-CoV 2 soit retardée, et cela va avec les mécanismes de tolérance immunitaire que j'ai précédemment décrits, énormément décrits, notamment avec l'activation du TLR 2 via le système Rage, les cellules myéloïdes, inhibitrices, l'expression de certains HLA inhibiteurs, enfin bref, plus sans compter les propriétés allergènes qui entraînent potentiellement des IgG4. Donc les IgG4 étant un marqueur également de cette de cette tolérance immunitaire. Bref, donc cette interaction de la nucléocapside avec TRIM 28 vient renforcer finalement les actions de la protéine Spike, et donc inhibent complètement la réponse immunitaire innée antivirale, ce qui fait, c'est qu'elle est retardée dans le temps. Qu'est-ce que ça signifie concrètement Il est fort probable qu'il existe une phase, une première phase lors de la contamination virale, qui soit silencieuse, asymptomatique. Puisqu'en fait, les symptômes, ce n'est, ce ne sont que la manifestation d'une activation du système immunitaire. Donc vous comprenez bien que si vous n'avez pas de symptômes, c'est que votre système immunitaire n'est pas activé correctement, et donc votre infection par le SARS-CoV 2 passe dans les premiers temps complètement inaperçue. Autrement dit aussi, nous avons soigné trop tard. Non seulement on n'a soigné que l'hyper inflammation, ne tenant compte que de l'hyper inflammation, sans tenir compte de la tolérance immunitaire, mais également nous avons soigné probablement avec un délai dans le temps. Donc du fait de cette phase asymptomatique, de cette phase retardée. Donc ce qui aurait permis d'ailleurs au virus de s'installer dans l'organisme tranquillou pépère, avant même l'enclenchement des des symptômes, et la mise en place des traitements précoces, dits précoces. Il faut savoir que d'autres virus latent, sont capables d'interagir avec TRIM vingt-huit, pardon. Il y a le b v, le cytomégalovirus, le papillomavirus, l'hépatite b ou encore le vih, le virus responsable du sida. Alors non seulement on a peut-être soigné avec un retard considérable, mais les injections anti Covid ont certainement rajouté une couche supplémentaire, notamment par la surexpression de certains récepteurs qui ont ouvert les portes de l'organisme au virus. En effet, en plus, si la spike virale persiste, le fait de faire produire de la spike par les cellules de l'organisme après l'administration des produits anti Covid, aura probablement eu comme conséquence un effet cumulatif spike viral plus spike vaccinal. De fait, il est rapporté dans la littérature scientifique que les injections, que les infections par le SARS-CoV-2 entraînent des dégâts cumulatifs, et ce, peu importe le statut vaccinal. Je répète, peu importe le statut vaccinal, que vous soyez vacciné ou non vacciné, ça ne change rien. Des infections répétées par le SARS-CoV 2 entraînent des dégâts cumulatifs. Et je pense que nous sommes encore loin du compte en ce qui concerne les dégâts occasionnés par la protéine Spike. Et ce d'autant plus qu'il s'agit d'une arme silencieuse. Elle va, comme je l'ai dit, désactiver le système immunitaire et ça va passer crème. Vous ne sentirez rien jusqu'au point de rupture. Ça veut bien dire qu'on peut déclencher des spycopathies, c'est-à-dire des maladies relatives à la persistance et à la présence de la protéine spike dans l'organisme, qu'elle soit d'origine virale ou vaccinale, dans le temps. Avec un délai, avec un certain retard. L'une des grandes catégories de spycopathies que l'on redoute et qu'on peut redouter énormément, ce sont les atteintes neurologiques. Comme la spike, elle est amyloïde et amyloïdogène. Elle est capable de former en elle-même des fibres hydrogels dégénératives, mais également de faire produire des fibres dégénératives par les cellules de l'organisme, des fibres comme celles qui sont impliquées dans la pathologie d'Alzheimer, de Parkinson, ou même la fibrillation de la protéine prions humaine. Et en plus, on va mettre la cerise sur la tarte au quetch, le virus, grâce à sa spike, peut utiliser ses fibres amyloïdes pour envahir l'organisme potentiellement. Je ne vais pas parler des propriétés allergènes qui peuvent avoir des conséquences comme des syndromes d'activation mastocytaire, Et ça, pas dans le temps, puisqu'elles persistent dans le temps. Donc ça fera comme des mastocytose-like en permanence. Donc comment soigner les spycopathies On a quelques pistes pour soutenir l'organisme, comme la curcumine, l'aspirine. Attention l'aspirine pas pour tout le monde, c'est un inhibiteur de l'activation des plaquettes. Donc si vous êtes sous anticoagulants ou si vous avez d'autres contre indications, ne prenez pas de l'aspirine. La quercétine ou la vitamine D, tout en gardant en tête quand même qu'il ne s'agit que de pansements. Mais c'est mieux que rien. La vitamine D est d'autant plus importante qu'elle peut renforcer la barrière hémato-encéphalique qui est largement attaquée par la protéine spike et le virus. Le fait de retrouver de la spike au niveau des artères cérébrales, ça ne sent pas très bon. Donc cette barrière hématoencéphalique normalement protège notre cerveau et donc elle est un, elle est attaquée, elle est perméabilisée, ce qui ouvre la voie en fait à un virus qui est neurotrope, qui adore le cerveau et qui est ami, avec une protéine Spike qui est amyloïde. Il n'y a pas que la protéine Spike qui est amyloïde, d'accord La protéine N aussi qui est amyloïde. Il y en a d'autres. Mais il nous est aujourd'hui essentiel, en fait, de trouver des outils de diagnostic pour aller chercher, pour aller traquer les spikopathies, notamment des outils de dépistage et de dosage de la protéine Spike, et de développer des thérapies pour bloquer le virus ou éliminer cette protéine Spike, attention, sans enclencher les catastrophes annexes. Il faut aussi traquer le virus, notamment dans les réservoirs, et aller chercher les dégâts tissulaires. On ne soigne pas des dégâts tissulaires comme on soigne une protéine persistante, comme on soigne un virus persistant. Et bien entendu, ces traitements se feront en fonction de votre cas. Chaque individu est différent. Il va donc falloir analyser chez vous ce qui se passe pour aller mieux vous soigner. Voilà. Sur ce, je vous laisse et je vous souhaite une bonne journée, je mettrai les références soit en haut du de la vidéo ou en bas de la vidéo en fonction de comment ça s'agence sur x. Je vous souhaite une bonne journée, au revoir.

Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients - Signal Transduction and Targeted Therapy Azvudine (FNC) is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase (RdRp). Recently, we discovered FNC an agent against SARS-CoV-2, and have taken it into Phase III trial for COVID-19 patients. FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC50 between 1.2 and 4.3 μM, depending on viruses or cells, and selective index (SI) in 15–83 range. Oral administration of FNC in rats revealed a substantial thymus-homing feature, with FNC triphosphate (the active form) concentrated in the thymus and peripheral blood mononuclear cells (PBMC). Treating SARS-CoV-2 infected rhesus macaques with FNC (0.07 mg/kg, qd, orally) reduced viral load, recuperated the thymus, improved lymphocyte profiles, alleviated inflammation and organ damage, and lessened ground-glass opacities in chest X-ray. Single-cell sequencing suggested the promotion of thymus function by FNC. A randomized, single-arm clinical trial of FNC on compassionate use (n = 31) showed that oral FNC (5 mg, qd) cured all COVID-19 patients, with 100% viral ribonucleic acid negative conversion in 3.29 ± 2.22 days (range: 1–9 days) and 100% hospital discharge rate in 9.00 ± 4.93 days (range: 2–25 days). The side-effect of FNC is minor and transient dizziness and nausea in 16.12% (5/31) patients. Thus, FNC might cure COVID-19 through its anti-SARS-CoV-2 activity concentrated in the thymus, followed by promoted immunity. nature.com

I noted that Harry blocked me after I drew parallels between HIV and Long Covid, focusing on immune and cognitive impacts. I discussed the role of Protein E, akin to HIV's Tat, and its implications for neurodegeneration. Evidence suggests that the neurovascular unit in Long Covid patients is damaged similarly to HIV. I highlighted studies connecting cytokine responses, monocyte behavior, and amyloid deposition in both conditions. The evolving understanding of these mechanisms raises concerns about cognitive impairment and the need for further research.

HIV-1 Tat-induced diarrhea evokes an enteric glia-dependent neuroinflammatory response in the central nervous system - Scientific Reports Despite the effectiveness of combined anti-retroviral therapy, human immunodeficiency virus (HIV) infected-patients frequently report diarrhea and neuropsychological deficits. It is claimed that the viral HIV-1 Trans activating factor (HIV-1 Tat) protein is responsible for both diarrhea and neurotoxic effects, but the underlying mechanisms are not known. We hypothesize that colonic application of HIV-1 Tat activates glial cells of the enteric nervous system (EGCs), leading to a neuroinflammatory response able to propagate to the central nervous system. We demonstrated that HIV-1 Tat-induced diarrhea was associated with a significant activation of glial cells within the colonic wall, the spinal cord and the frontal cortex, and caused a consistent impairment of the cognitive performances. The inhibition of glial cells activity by lidocaine, completely abolished the above-described effects.

SARS-CoV-2 infection triggers pro-atherogenic inflammatory responses in human coronary vessels - Nature Cardiovascular Research Patients with coronavirus disease 2019 (COVID-19) present increased risk for ischemic cardiovascular complications up to 1 year after infection. Although the systemic inflammatory response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection likely contributes to this increased cardiovascular risk, whether SARS-CoV-2 directly infects the coronary vasculature and attendant atherosclerotic plaques remains unknown. Here we report that SARS-CoV-2 viral RNA is detectable and replicates in coronary lesions taken at autopsy from severe COVID-19 cases. SARS-CoV-2 targeted plaque macrophages and exhibited a stronger tropism for arterial lesions than adjacent perivascular fat, correlating with macrophage infiltration levels. SARS-CoV-2 entry was increased in cholesterol-loaded primary macrophages and dependent, in part, on neuropilin-1. SARS-CoV-2 induced a robust inflammatory response in cultured macrophages and human atherosclerotic vascular explants with secretion of cytokines known to trigger cardiovascular events. Our data establish that SARS-CoV-2 infects coronary vessels, inducing plaque inflammation that could trigger acute cardiovascular complications and increase the long-term cardiovascular risk. Eberhardt et al. show that SARS-CoV-2 infects human coronary lesions where it preferentially targets plaque macrophages, triggering plaque inflammation and potentially leading to acute cardiovascular complications and long-term cardiovascular risks in patients with COVID-19. nature.com

SARS-CoV-2 in severe COVID-19 induces a TGF-β-dominated chronic immune response that does not target itself - Nature Communications The pathogenesis of severe COVID-19 reflects an inefficient immune reaction to SARS-CoV-2. Here we analyze, at the single cell level, plasmablasts egressed into the blood to study the dynamics of adaptive immune response in COVID-19 patients requiring intensive care. Before seroconversion in response to SARS-CoV-2 spike protein, peripheral plasmablasts display a type 1 interferon-induced gene expression signature; however, following seroconversion, plasmablasts lose this signature, express instead gene signatures induced by IL-21 and TGF-β, and produce mostly IgG1 and IgA1. In the sustained immune reaction from COVID-19 patients, plasmablasts shift to the expression of IgA2, thereby reflecting an instruction by TGF-β. Despite their continued presence in the blood, plasmablasts are not found in the lungs of deceased COVID-19 patients, nor does patient IgA2 binds to the dominant antigens of SARS-CoV-2. Our results thus suggest that, in severe COVID-19, SARS-CoV-2 triggers a chronic immune reaction that is instructed by TGF-β, and is distracted from itself. Our understanding on the humoral immunity induced by SARS-CoV-2 is still lacking. Here the authors analyze B cell responses at the single cell level to find that, in severe COVID-19 patients, plasmablasts shift from IFN to TGFβ instruction to produce IgA antibodies that are not specific to dominant SARS-CoV-2 antigens. nature.com

Were I experiencing the silencing of the Cystic Fibrosis Transmembrane Conductance Receptor, I too would have the Quality of Life of a CF patient. Inflammation in the COVID-19 airway is due to inhibition of CFTR signaling by the SARS-CoV-2 spike protein https://www.nature.com/articles/s41598-024-66473-4

Inflammation in the COVID-19 airway is due to inhibition of CFTR signaling by the SARS-CoV-2 spike protein - Scientific Reports SARS-CoV-2-contributes to sickness and death in COVID-19 patients partly by inducing a hyper-proinflammatory immune response in the host airway. This hyper-proinflammatory state involves activation of signaling by NFκB, and unexpectedly, ENaC, the epithelial sodium channel. Post-infection inflammation may also contribute to "Long COVID"/PASC. Enhanced signaling by NFκB and ENaC also marks the airway of patients suffering from cystic fibrosis, a life-limiting proinflammatory genetic disease due to inactivating mutations in the CFTR gene. We therefore hypothesized that inflammation in the COVID-19 airway might similarly be due to inhibition of CFTR signaling by SARS-CoV-2 spike protein, and therefore activation of both NFκB and ENaC signaling. We used western blot and electrophysiological techniques, and an organoid model of normal airway epithelia, differentiated on an air–liquid-interface (ALI). We found that CFTR protein expression and CFTR cAMP-activated chloride channel activity were lost when the model epithelium was exposed to SARS-CoV-2 spike proteins. As hypothesized, the absence of CFTR led to activation of both TNFα/NFκB signaling and α and γ ENaC. We had previously shown that the cardiac glycoside drugs digoxin, digitoxin and ouabain blocked interaction of spike protein and ACE2. Consistently, addition of 30 nM concentrations of the cardiac glycoside drugs, prevented loss of both CFTR protein and CFTR channel activity. ACE2 and CFTR were found to co-immunoprecipitate in both basal cells and differentiated epithelia. Thus spike-dependent CFTR loss might involve ACE2 as a bridge between Spike and CFTR. In addition, spike exposure to the epithelia resulted in failure of endosomal recycling to return CFTR to the plasma membrane. Thus, failure of CFTR recovery from endosomal recycling might be a mechanism for spike-dependent loss of CFTR. Finally, we found that authentic SARS-CoV-2 virus infection induced loss of CFTR protein, which was rescued by the cardiac glycoside drugs digitoxin and ouabain. Based on experiments with this organoid model of small airway epithelia, and comparisons with 16HBE14o- and other cell types expressing normal CFTR, we predict that inflammation in the COVID-19 airway may be mediated by inhibition of CFTR signaling by the SARS-CoV-2 spike protein, thus inducing a cystic fibrosis-like clinical phenotype. To our knowledge this is the first time COVID-19 airway inflammation has been experimentally traced in normal subjects to a contribution from SARS-CoV-2 spike-dependent inhibition of CFTR signaling. nature.com

Astrocytes of the A1 phenotype are observed in a number of neurodegenerative disorders including HIV Associated Neurocognitive Decline, Parkinson's Disease, Epilepsy, Traumatic Brain Injury, and Alzheimer's Disease. Their presence is indicative of a neurotoxic environment.

When the environment becomes ischemic, or there is a reduction in blood flow, the A2 phenotype can be found. Both the A1 and A2 phenotype contribute to impaired glymphatic system involvement, leading to inflammation and the accumulation of toxic waste products.

Dysregulation of brain and choroid plexus cell types in severe COVID-19 - Nature Although SARS-CoV-2 primarily targets the respiratory system, patients with and survivors of COVID-19 can suffer neurological symptoms1–3. However, an unbiased understanding of the cellular and molecular processes that are affected in the brains of patients with COVID-19 is missing. Here we profile 65,309 single-nucleus transcriptomes from 30 frontal cortex and choroid plexus samples across 14 control individuals (including 1 patient with terminal influenza) and 8 patients with COVID-19. Although our systematic analysis yields no molecular traces of SARS-CoV-2 in the brain, we observe broad cellular perturbations indicating that barrier cells of the choroid plexus sense and relay peripheral inflammation into the brain and show that peripheral T cells infiltrate the parenchyma. We discover microglia and astrocyte subpopulations associated with COVID-19 that share features with pathological cell states that have previously been reported in human neurodegenerative disease4–6. Synaptic signalling of upper-layer excitatory neurons—which are evolutionarily expanded in humans7 and linked to cognitive function8—is preferentially affected in COVID-19. Across cell types, perturbations associated with COVID-19 overlap with those found in chronic brain disorders and reside in genetic variants associated with cognition, schizophrenia and depression.

SARS-CoV-2 infection triggers pro-atherogenic inflammatory responses in human coronary vessels https://www.nature.com/articles/s44161-023-00336-5

SARS-CoV-2 infection triggers pro-atherogenic inflammatory responses in human coronary vessels - Nature Cardiovascular Research Patients with coronavirus disease 2019 (COVID-19) present increased risk for ischemic cardiovascular complications up to 1 year after infection. Although the systemic inflammatory response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection likely contributes to this increased cardiovascular risk, whether SARS-CoV-2 directly infects the coronary vasculature and attendant atherosclerotic plaques remains unknown. Here we report that SARS-CoV-2 viral RNA is detectable and replicates in coronary lesions taken at autopsy from severe COVID-19 cases. SARS-CoV-2 targeted plaque macrophages and exhibited a stronger tropism for arterial lesions than adjacent perivascular fat, correlating with macrophage infiltration levels. SARS-CoV-2 entry was increased in cholesterol-loaded primary macrophages and dependent, in part, on neuropilin-1. SARS-CoV-2 induced a robust inflammatory response in cultured macrophages and human atherosclerotic vascular explants with secretion of cytokines known to trigger cardiovascular events. Our data establish that SARS-CoV-2 infects coronary vessels, inducing plaque inflammation that could trigger acute cardiovascular complications and increase the long-term cardiovascular risk. Eberhardt et al. show that SARS-CoV-2 infects human coronary lesions where it preferentially targets plaque macrophages, triggering plaque inflammation and potentially leading to acute cardiovascular complications and long-term cardiovascular risks in patients with COVID-19. nature.com

SARS-CoV-2 infects cells lining the blood-retinal barrier and induces a hyperinflammatory immune response in the retina via systemic exposure Author summary SARS-CoV-2 is known to cause several ocular manifestations in COVID-19 patients; however, the role of eyes in viral transmission and ocular tissue tropism remains elusive. The presence of viral remnants in various ocular tissues and fluids from COVID-19 patients has led to an assumption that SARS-CoV-2 may be transmitted through the eyes. Here, we show that SARS-CoV-2 ocular tropism is through cells lining the BRB. SARS-CoV-2 not only infects the various parts of the eye via systemic exposure but also induces a hyperinflammatory immune and antiviral response in the retina. Unexpectedly, the corneal epithelium was found to be resistant to SARS-CoV-2 infection, and ocular exposure of SARS-CoV-2 failed to cause lung pathology and moribund illness. Cells lining the BRB showed induced expression of viral entry receptors and enhanced susceptibility towards SARS-CoV-2-induced cell death, which is further potentiated with comorbidities such as hyperglycemia. Our findings from this study shed light on the role of BRB in SARS-CoV-2 ocular tropism and the role of eyes in viral transmission. journals.plos.org

HIV-1 Tat-Mediated Apoptosis in Human Blood-Retinal Barrier-Associated Cells https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0095420

HIV-1 Tat-Mediated Apoptosis in Human Blood-Retinal Barrier-Associated Cells HIV-1-associated ocular complications, such as microvasculopathies, can lead to the loss of vision in HIV-1-infected patients. Even in patients under highly active antiretroviral therapy, ocular lesions are unavoidable. Ocular complications have been demonstrated to be closely related to the breakdown of the blood-retinal-barrier (BRB); however, the underlying mechanism is not clear. The data from this study indicated that the HIV-1 Tat protein induced the apoptosis of human retinal microvascular endothelial cells (HRMECs) and retinal pigmen epithelium (RPE) cells, which compose the inner BRB and the outer BRB, respectively. In addition, this study found that the activation of N-methyl-D-aspartate receptors (NMDARs) was involved in the apoptosis of RPE cells, but it caused no changes in HRMECs. Furthermore, both cell types exhibited enhanced expression of Bak, Bax and Cytochrome c. The inhibition of Tat activity protected against the apoptosis induced by NMDAR activation and prevented the dysregulation of Bak, Bax and Cytochrome c, revealing an important role for the mitochondrial pathway in HIV-1 Tat-induced apoptosis. Together, these findings suggest a possible mechanism and may identify a potential therapeutic strategy for HIV-1-associated ocular complications. journals.plos.org

To further demonstrate the genius of Kenneth Podell, let's look to this document. HIV-1 Encephalopathy and Aids Dementia Complex https://www.ncbi.nlm.nih.gov/books/NBK507700/

HIV-1 Encephalopathy and Aids Dementia Complex Neurocognitive deficits are the presenting complaint in 4% to 15% of patients diagnosed with HIV. Patients may present with nonspecific complaints such as deficits in memory, concentration, attention, and motor skills. These symptoms are common in many disorders, and accurate diagnosis is critical for appropriate treatment. The AIDS dementia complex (ADC) was first defined in 1986. It was a frequent feature of HIV disease before antiretroviral therapy (ART) and highly active antiretroviral therapy (HAART) came into common use in the mid-1990s. In addition to medical comorbidities, patients also frequently suffer from various mental or psychosocial issues that can affect cognitive function, including mood disorders, post-traumatic stress disorder (PTSD), and substance abuse or dependence. Increased risk of opportunistic infections, tumors, and side effects of antiretroviral drugs may also contribute to neurologic effects. Patients can experience delirium as part of the acute HIV syndrome or develop dementia during the later stages of their disease.[1][2] ncbi.nlm.nih.gov

Microglial Implications in SARS-CoV-2 Infection and COVID-19: Lessons From Viral RNA Neurotropism and Possible Relevance to Parkinson’s Disease Since December 2019, humankind has been experiencing a ravaging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the second coronavirus pandemic in a decade after the Middle East respiratory syndrome coronavirus (MERS-CoV) disease in 2012. Infection with SARS-CoV-2 results in Coronavirus disease 2019 (COVID-19), which is responsible for over 2.13.1 million deaths worldwide. With the emergence of a second and a third wave of infection across the globe, and the rising record of multiple reinfections and relapses, SARS-CoV-2 infection shows no sign of abating. In addition, it is now evident that SARS-CoV-2 infection presents with neurological symptoms that include early hyposmia, ischemic stroke, meningitis, delirium and falls, even after viral clearance. This may suggest chronic or permanent changes to the neurons, glial cells, and/or brain vasculature in response to SARS-CoV-2 infection or COVID-19. Within the central nervous system (CNS), microglia act as the central housekeepers against altered homeostatic states, including during viral neurotropic infections. In this review, we highlight microglial responses to viral neuroinfections, especially those with a similar genetic composition and route of entry as SARS-CoV-2. As the primary sensor of viral infection in the CNS, we describe the pathogenic and neuroinvasive mechanisms of RNA viruses and SARS-CoV-2 vis-à-vis the microglial means of viral recognition. Responses of microglia which may culminate in viral clearance or immunopathology are also covered. Lastly, we further discuss the implication of SARS-CoV-2 CNS invasion on microglial plasticity and associated long-term neurodegeneration. As such, this review provides insight into some of the mechanisms by which microglia could contribute to the pathophysiology of post-COVID-19 neurological sequelae and disorders, including Parkinson’s disease, which could be pervasive in the coming years given the growing numbers of infected and re-infected individuals globally. frontiersin.org

Every single cell type that constitutes the Central Nervous System in HIV has been productively infected by SARS-Cov-2, with microglia serving as the primary cell type. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6821723/

Microglial Cells: The Main HIV-1 Reservoir in the Brain Despite efficient combination of the antiretroviral therapy (cART), which significantly decreased mortality and morbidity of HIV-1 infection, a definitive HIV cure has not been achieved. Hidden HIV-1 in cellular and anatomic reservoirs is the major hurdle ... ncbi.nlm.nih.gov

While folk "elucidate" and "tease out" that which could be explained had they read, as I have done, individuals are experiencing a decline in their cognition, CD4 population, and creatine clearance levels.

@dbdugger - Daniel Brittain Dugger

What I find to be remarkable is so many folk bitch about endothelial damage and continue to ignore the depletion of the CD4 compartment, as if they are not related. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7268551/https://pbs.twimg.com/card_img/1696143174819807232/m2AAd_8_?format=jpg&name=small

"Vascular reactivity index, marker of endothelial dysfunction, showed a significant correlation with lower nadir CD4 count (p = 0.003) as well as low-density lipoprotein cholesterol (p = 0.02)."

I've all but given up on those who were unfortunately placed in a position to determine the fate of our society. You probably should, too.

The fight against the virus requires a new approach. Drawing from HIV medicine, we see the need for pharmaceutical interventions alongside vaccine development. Strategies like Post Exposure Prophylaxis, PreExposure Prophylaxis, and Treatment as Prevention have proven effective. To preserve immune competence and cognition, we must adopt Treatment as Prevention for chronic SARSCov2 infections. Durable suppression is crucial to prevent resistant strains. However, the lack of viral load tests hinders progress. Combination therapy is essential, targeting multiple points in the replication cycle. Let's repurpose possible candidates and prioritize reduction in viral load to ensure success. Antiviral deferral has dire consequences. We must act now.

@dbdugger - Daniel Brittain Dugger

No, we will not conquer the virus. Considering the fact that we have yet to borrow from 40 years of HIV medicine, one has to wonder if we really want to conquer the virus.

@dbdugger - Daniel Brittain Dugger

With SARS-Cov-2, it is quite easy to observe that which we have seen with HIV over the past 40 years. Viral evolution outpacing vaccine development. An aversion to rely upon nonpharmaceutical interventions, masks with SARS-Cov-2 and condoms with HIV.

@dbdugger - Daniel Brittain Dugger

With HIV medicine, the decision was made to pursue pharmaceutical interventions contemporaneously with vaccine development. First, came Post Exposure Prophylaxis.

@dbdugger - Daniel Brittain Dugger

The next innovation allowed for an individual to take their health into their own hands, to prevent the acquisition of HIV. It is referred to as Pre-Exposure Prophylaxis.

@dbdugger - Daniel Brittain Dugger

Finally, one of the most remarkable innovations, allows an individual living with HIV to prevent its transmission and burdening another individual with the condition. It is referred to as Treatment as Prevention.

@dbdugger - Daniel Brittain Dugger

With millions living with a chronic SARS-Cov-2 infection, it is quite clear that if we have any interest in preserving what is left of these individual's immune competence and cognition, we must go in reverse. Treatment as Prevention must be the strategy adopted.

@dbdugger - Daniel Brittain Dugger

We knew this was going to be necessary as soon as the first monoclonal was wiped out as it was suggestive of either viral persistence or too short of a duration of therapy.

@dbdugger - Daniel Brittain Dugger

Considering evidence of microglia involvement, we now know that durable suppression will be required for life so as to prevent the emergence of resistant strains through "CNS Escape."

@dbdugger - Daniel Brittain Dugger

Unfortunately, we are without the tools to allow us to even begin the process of implementing a Treatment as Prevention model. Namely, that of a viral load test.

@dbdugger - Daniel Brittain Dugger

It is through the use of a viral load test that those in HIV medicine were able to determine the target log copy that would not only prevent disease progression but forward transmission, as well.

@dbdugger - Daniel Brittain Dugger

As for your intimation that combination therapy will be required, it most certainly will. The use of what is described as a monotherapy invites resistance developing as a consequence of not targeting enough points in the replication cycle.

@dbdugger - Daniel Brittain Dugger

Additionally, the literature is quite clear as to what is required to arrest the cortical thinning, cortical atrophy, and begin the process of resolving frontal lobe hypometabolism. It is combination therapy.

@dbdugger - Daniel Brittain Dugger

Are there possible candidates that could be repurposed? It appears so. However, without the viral load test mentioned above, there isn't a way to appreciate a log copy reduction during the drug trials.

@dbdugger - Daniel Brittain Dugger

An inability to observe this reduction allows individuals to assume that the drug is not working, ignoring the fact that millions have been allowed to have their viral loads shoot through the roof as a consequence of antiviral deferral.
