MAPT and infection: We therefore performed live HCMV infection of human cerebral organoids (multiplicity of infection [MOI] = 2) followed by flow cytometry based detection of viral abundance, cell death markers, and AD‐associated neuropathological molecular features amyloid beta‐42 (Aβ42) and phosphorylated Tau‐Thr212 (pTau‐212) (Figure 4A) using our previous protocols.59
