RXFP3 and Obesity: Rats in which obesity was induced with a high fat diet and refeeding after food deprivation, displayed increased expression of RXFP3 in the central amygdala, as well as in the paraventricular hypothalamic nucleus, NI and nucleus of the olfactory tract, whereas such changes were not observed in rats in which a high fat diet did not induce obesity (Lenglos et al., 2014).
