The increasing incidence of Alzheimer’s disease(AD) in the aging population, indicates the critical need for the development of novel targeted molecular therapies for ameliorating AD pathology. Moreover, clinical and preclinical evidence demonstrates that peroxisomal proliferator activating receptors(PPAR) agonists regulate energy and lipid homeostasis in models of diabetes, as well as improve spatial memory in animal models of AD(Khan et al., 2019).
