Credit @NestCommander Why would fibrinogen be auto fluorescing , explain the mechanisms in necessary detail for our discussions on amyloid. 3/3 ChatGPT said: Fibrinogen exhibits autofluorescence under certain conditions due to its structural and biochemical properties. In the context of amyloid discussions, understanding fibrinogen autofluorescence is important because fibrinogen can be involved in amyloid formation and aggregation, particularly in neurodegenerative diseases and coagulopathies. Below are the key mechanisms explaining why fibrinogen might autofluoresce: 1. Intrinsic Fluorophores in Fibrinogen Fibrinogen contains aromatic amino acids that exhibit intrinsic fluorescence: Tryptophan (Trp) (~340 nm excitation, ~350 nm emission) Tyrosine (Tyr) (~275 nm excitation, ~303 nm emission) Phenylalanine (Phe) (~258 nm excitation, weak emission at ~282 nm) These residues contribute to fibrinogen’s natural fluorescence, with tryptophan being the dominant fluorophore. The fluorescence properties can change depending on fibrinogen’s structural state or interactions with other molecules. 2. Structural Perturbations and Amyloid Formation When fibrinogen undergoes misfolding or forms amyloid-like aggregates, its intrinsic fluorescence properties can be altered due to: Changes in aromatic residue microenvironments – As fibrinogen aggregates, tryptophan and tyrosine residues may be exposed or buried differently, leading to shifts in fluorescence emission. Enhanced beta-sheet content – Amyloid fibrils are rich in beta-sheet structures, which can alter the electronic environment of aromatic residues, modifying fluorescence characteristics. 3. Post-Translational Modifications Oxidation & Glycation – Oxidative stress or non-enzymatic glycation can introduce fluorescent adducts to fibrinogen. Advanced Glycation End-products (AGEs) – These accumulate in amyloid-associated conditions and exhibit strong autofluorescence in the 350–450 nm range upon UV excitation. 4. Interaction with Amyloid-Specific Dyes Amyloid dyes like Thioflavin T (ThT) or Congo Red (CR) bind to fibrinogen amyloid-like structures and exhibit fluorescence enhancement. This suggests that fibrinogen, when adopting amyloid-like conformations, may have similar autofluorescent properties. Relevance to Amyloid Studies Fibrinogen’s autofluorescence is particularly significant in: Neurodegeneration (e.g., Alzheimer’s Disease) – Fibrinogen interacts with amyloid-beta (Aβ) and contributes to fibrillar deposits. Hypercoagulability & Systemic Amyloidosis – Altered fibrin clot structures in amyloid-prone conditions may show enhanced fluorescence due to misfolding and aggregation. Thus, fibrinogen's autofluorescence is a useful property when studying its role in amyloid diseases, allowing for non-invasive detection and structural analysis of its pathological aggregates.
