Post-mortem Alzheimerĺs diseased brain specimens reveals significant levels of A▀ (11-40/42) within insoluble amyloid pools. The ▀-secretase enzyme or ▀-amyloid precursor protein-cleaving enzyme (BACE) generates the N terminus of A▀, ultimately leading to the production of full-length A▀ (1-40/42) or truncated A▀ (11-40/42). The abundance of A▀ (11-40/42) produced by BACE suggests that their roles in AD pathogenesis may be important.
