title: Role of Cortistatin in the Stressed Immune System.
abstract: The immune system is faced with the daunting job of defending the organism against invading pathogens, while at the same time preserving the body integrity and maintaining tolerance to its own tissues. Loss of self-tolerance compromises immune homeostasis and leads to the onset of autoimmune disorders. The identification of endogenous factors that control immune tolerance and inflammation is a key goal for immunologists. Evidences from the last decade indicate that the neuropeptide cortistatin is one of the endogenous factors. Cortistatin is produced by immune cells and through its binding to various receptors, it exerts potent anti-inflammatory actions and participates in the maintenance of immune tolerance at multiple levels, especially in immunological disorders. Cortistatin emerges as a key element in the bidirectional communication between the neuroendocrine and immune systems aimed at regulating body homeostasis.
