To elucidate the biochemical structure, formation mechanisms, and pathological significance of anomalous fibrinaloid microclot complexes across inflammatory conditions.
Evaluated the composition and phenotypic heterogeneity of microclot complexes derived from inflammatory models and ischaemic stroke thrombi.
Assessed amyloid nature using Congo red dye staining visualized under polarized light.
Fibrinaloid microclots demonstrated characteristic 'apple-green' birefringence under polarized light after Congo red staining, verifying their amyloid nature.
Microclot complexes nucleate on damaged membranes, entrap neutrophil extracellular traps (NETs) and antiproteolytic proteins, conferring resistance to normal fibrinolysis.
Aggregations of amyloid-rich microclots were identified as a mechanism driving the formation of occlusive macroclots observed in ischaemic stroke.
