Central control of lactogenic receptors in liver membranes: effect of hypothalamic deafferentation

The regulation by the central nervous system of a lactogenic receptor, present in the rat liver, was studied. The receptor, which is present in very low concentration or absent in the male rat, can be induced by anterior hypothalamic deafferentation, resulting in a typically female level of the receptor in lesioned male animals. Our observations indicate an important role of the brain in regulation of peripheral lactogenic receptors.
