Dystrophic neurites
WebThese structures contain a core of aggregated extracellular Aβ that is surrounded by swollen, dystrophic neurites and microglial processes ( 7 – 13 ). Multiple studies in humans and mice have additionally reported an elevated abundance of putative lysosomes and/or lysosomal proteins around amyloid plaques ( 9 – 11, 14 – 16 ). WebJun 3, 2024 · We found that SYNJ1 immunoreactivity was associated with dystrophic neurites surrounding amyloid plaques where SYNJ1 and the presynaptic marker Synaptophysin were partially colocalized. SYNJ1 immunoreactivity was also detected in actin positive Hirano bodies and in a proportion of the NFTs.
