Arrowheads: green for what seems to me to be high endothelial venules; red for punctate positivity in basal cells of mucosal epithelium.
Arrowheads indicate punctate positivity:
green for basal cells in mucosal epithelium; red for strange stuff.
Many amyloid plaques are seen
Frontal cortex showing negative amyloid plaques. Neuropil is positive( punctate).
Around each plaque there is intensely positive punctate positivity.
Interesting: red arrowheads indicate positive processes of an alpha synuclein- positive cell body.
Any suggestions out there?
Coloured arrowheads indicate features: red for classic Lewy body; green for dying neurone?; blue for positivity in cytoplasm of seemingly viable neurone ( obvious nucleus and prominent nucleolus).
