Other in vitro autoradiography studies of human AD brain sections with N-methyl lansoprazole (Figure 4c, NML) labeled with [11C] (Figure 4d, [11C]NML) and [18F] (Figure 4e, [18F]NML) revealed a high affinity for tau aggregates in AD, with 12-fold selectivity for tau over Aβ (KD amyloid/KD tau) [132]. This evidence concerns the gene MAPT and Alzheimer disease.
