Hypothalamic MC4R receptors are Galphas-coupled GPCR’s that mediate the satiety response to αMSH. MC4R expression predominates in the PVN/VMH regions of the hypothalamus, regulating satiety gene expression (e.g. Bdnf). Human MC4R mutations often result in compromised Galphas-cAMP-PKA signalling and obesity onset. However, downstream signalling pathways have yet to be elucidated. We have investigated the potential for αMSH to stimulat...
