MAPT and Alzheimer disease: Building on our previous findings that CAP enhances antioxidant capacity and extends the lifespan in wild-type C. elegans [21], in this study, we further determined the physicochemical properties of CAP, such as its chemical composition, microscopic morphology, and thermal properties, etc., and utilized Aβ1–42 transgenic C. elegans (CL4176) and tau transgenic C. elegans (BR5270) as models to investigate the effects of CAP on physiological phenotypes, Aβ1–42 and tau-induced AD phenotypes, antioxidant activity, and gene expression.
