Experimental sub‐groups of macaques also received two injections (6 months apart) of recombinant oligomeric Aβ peptides in lateral ventricles (AD‐tau/Aβ and CTL‐tau/Aβ groups), or sham injections (AD‐tau/sham and CTL‐tau/sham groups) (Figure 1G). The gene discussed is MAPT; the disease is Alzheimer disease.
