APOE and Alzheimer disease: Can infect neurons, astrocytes and microglia seen in AD brains (Balin et al., 1998), attachment to microglia and astrocytes enhanced by ApoE4 (Gérard et al., 2008) and higher bacterial loads in AD ApoE4 carrier brains (Gérard et al., 2005). Isolated and cultured from AD brain (Dreses-Werringloer et al., 2009). Persistent infection (Chacko et al., 2022).Induces Amyloid deposits in mice via intranasal infection (Little et al., 2004).
