title: Pharmacological strategies for targeting BAT thermogenesis.
abstract: Biopsies following positron emission tomography coupled to computer tomography (PET-CT) imaging have confirmed the presence of thermogenically active brown adipose tissue (BAT) in adult humans, leading to suggestions that it could be stimulated to treat obesity and its associated morbidities. The mechanisms regulating thermogenesis in BAT are better understood than ever before, and many new hypotheses for increasing the amount of brown fat or its activity are currently being explored. The challenge now is to identify safe ways to manipulate specific aspects of the physiological regulation of thermogenesis, in a manner that will be bioenergetically effective. This review outlines the nature of these regulatory mechanisms both in terms of their cellular specificity and probable effectiveness given the physiological paradigms in which thermogenesis is activated. Similarly, their potential for being targeted by new or existing drugs is discussed, drawing on the known mechanisms of action of various pharmacological agents and some probable limitations that should be considered.
