The main antibodies employed are against Amyloid Beta (Aβ), which highlights plaques (Figure 1b,f) (together with amyloid in the walls of vessels-cerebral amyloid angiopathy (CAA)), and hyperphosphorylated (HP)-tau in the form of neuritic plaques (Figure 1c), neurofibrillary tangles (Figure 1d), and neuropil threads (Figure 1c–e). This evidence concerns the gene MAPT and cerebral amyloid angiopathy.
