IL1B and Alzheimer disease: In vivo, 7 days of CBD treatment dose-dependently attenuated Aβ-evoked neuroinflammation [e.g., CBD inhibited expression of glial fibrillary acidic protein (GFAP), inducible nitric oxide synthase (iNOS), and interleukin 1 beta (IL-1β)] in a pharmacological mouse model of AD (Esposito et al., 2007b), which was mediated via PPARγ and associated with increased neurogenesis (see Figure 1; Esposito et al., 2011).
