Phosphatidylinositol binding clathrin assembly protein, PICALM (aka CALM) assembles adaptor protein-2 (AP-2) to clathrin, thus participating in clathrin-mediated endocytosis. We have previously reported that the level of full-length PICALM is decreased in AD brains; PICALM was co-localised with phosphorylated tau in NFTs and in granulovacuolar degenerations (GVDs) in the brains of AD patients and of individuals with Down syndrome but was not observed in amyloid plaques (Ando et al., 2013).
Double immunostaining for PICALM and anti-phosphotau antibodies (AT8 and PHF1) showed a co-localisation of PICALM and phosphotau in Pick bodies of Pick disease
A highly significant correlation was found between decreased levels of PICALM and increased levels of LC3-II (p=0.0032) or decreased levels of Beclin-1 (p=0.0295) in the total brain lysates from these diseases (Fig 6D,E).
In PSP cases, both coiled bodies (Fig. 2 D-F) and NFTs (Fig. 2G-I) in the striatum showed a complete co-localisation of PICALM and phosphotau immunoreactivies.
