Although estrogens exert a pronounced protective effect on multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), their therapeutic application has been limited by undesirable side effects thought to be mediated primarily through estradiol binding to intracellular estrogen receptor alpha (iERα). In this study, we found that signaling through the putative membrane estrogen receptor, GPR30, was sufficient to mediate protection against EAE, which was significantly impaired in GPR30 gene-deficient mice. Treatment with G-1, an agonist that selectively activates GPR30 without engagement of the iERs, retained estradiol's ability to protect against clinical and histological EAE without estradiol-associated side effects, deviated cytokine profiles and enhanced suppressive activity of CD4+Foxp3+ Treg cells through a GPR30- and programmed death 1 (PD-1)-dependent mechanism. This study is the first to evaluate the protective effect of GPR30 activation on EAE, and provides a strong foundation for the clinical application of GPR30 agonists such as G-1 in MS.
