Ghrelin induces time-dependent modulation of thermoregulation in the cold.

Fasted mice show torpor-like hypothermia in the cold in their inactive phase. The aim of the present study was to elucidate whether leptin and/or ghrelin are involved in this reaction and to identify its neurophysiological mechanisms. In ob/ob mice, which lack leptin, metabolic heat production (oxygen consumption, Vo(2)) was suppressed in 20°C cold in both… CONTINUE READING
