PPARD and nervous system disorder: In the recent review article, Gamdzyk et al. (2020) compared neuroprotective efficacy of PPAR-β/ δ agonists to PPAR-α and PPAR-γ and conclude that despite of being the most highly expressed in CNS, the available data on the effect of this receptor agonists in stroke as well as other neurological disorders are relatively poor and thus needing further investigations.
