Extended Data Fig. 8: Lipid transport-related proteins are expressed in axonal spheroids around amyloid plaques in AD human postmortem brains.

A. Representative immunofluorescence confocal images of the top-ranked lipid-related proteomic hits, including APOE, HDLBP, C3, HEXB and TMEM30A in AD humans. Lipid transport-related proteins are shown in red. Neurofilament marker SMI312 (grey) indicates the neuronal branches, and axonal spheroid structures around amyloid plaques (ThioflavinS, blue). Scale bar = 5 μm. Quantification was performed in n = 3 AD human brains. Protein expression quantifications can be found in Table S2. B. Immunofluorescence confocal image shows HEXB (grey) expressed in neuronal cell bodies (NeuN, green) and axonal spheroids (SMI312, green) in AD human postmortem brain (n = 3). Two different HEXB antibodies were used for validation. Scale bar = 5 μm.
