Contrary to the expectation, rats at an ambient temperature of 40°C displayed less care of the fur than rats do at an ambient temperature of 24°C. Rats in the 40°C environment curtailed their activities by lying flat; the autonomic response salival secretion appeared excessively, but the saliva was not spread on the fur by means of washing or licking. In a 4°C environment the rats displayed as much care of the fur as they do in a 24°C environment. In the 4°C environment the location of body contact for grooming changed compared to the 24°C environment. Scratching did not play a role according the lining up of the hairs during piloerection.

Leptin Signaling

The adipokine leptin acts on the brain to regulate energy balance but specific functions in many brain areas remain poorly understood. Among these, the preoptic area (POA) is well known to regulate core body temperature by controlling brown fat thermogenesis, and we have previously shown that glutamatergic, long-form leptin receptor (Lepr)-expressing neurons in the POA are stimulated by warm ambient temperature and suppress energy expenditure and food intake. Here we further investigate the role of POA leptin signaling in body weight regulation and its relationship to body temperature regulation in mice. We show that POA Lepr signaling modulates energy expenditure in response to internal energy state, and thus contributes to body weight homeostasis. However, POA leptin signaling is not involved in ambient temperature-dependent metabolic adaptations. Our study reveals a novel cell population through which leptin regulates body weight.
