Obesity is a hallmark of aging in many Western societies, and is a precursor to numerous serious age-related diseases. Ghrelin (Ghrl), via its receptor (growth hormone secretagogue receptor, GHS-R), is shown to stimulate GH secretion and appetite. Surprisingly, our previous studies showed that Ghrl(-/-) mice have impaired thermoregulatory responses to cold and fasting stresses, while Ghsr(-/-) mice are adaptive.
