Brown adipose tissue thermogenesis above the lower critical temperature

Abstract

Heat-acclimated rats show lighter IBAT deposit with different gross composition and lower GDP-binding than controls at thermoneutrality.A thermal disactivation of the tissue is then inferred.Cafeteria regime increased IBAT mass and GDP-binding when offered to rats at a thermoneutral ambient temperature.These results indicate that BAT thermogenesis at thermoneutrality is not the lowest one of the tissue and that diet-induced thermogenesis can take place even at thermoneutrality.
