Adipose tissue secretes a variety of proteins with important roles in metabolism, reproduction, immunity and cardiovascular function. The endocrine function of adipose tissue, especially that of leptin, is linked to energy storage and thus might provide insights into obesity and other diseases associated with energy imbalance. This review highlights the current understanding of the actions of leptin in the brain, with particular emphasis on transport across the blood-brain barrier, signal transduction, neuropeptide targets and roles during fasting and obesity. Moreover, data pertaining to the potential central effects of adiponectin, cytokines and resistin on energy homeostasis, glucose and lipid metabolism are discussed.
