Abstract
Brown adipocytes are known for their thermogenic potential, initiated by the activation of adrenergic receptors coupled to a G protein. The activation of these receptors in cells with high metabolic activity leads to an increase of intracellular cyclic AMP (cAMP), which, in excess, is pulled out of the cell by MRPs (Multidrug Resistance Proteins) channels. Extracellular cAMP/AMP can be co…
