ReviewTherapeutic implications of innate immune system in acute pancreatitis.
Acute pancreatitis (AP) is an inflammatory disorder of the pancreas encompassing a cascade of cellular and molecular events. It starts from premature activation of zymogens with the involvement of innate immune system to a potential systemic inflammatory response and multiple organ failure. Leukocytes are the major cell population that participate in the propagation of the disease. Current understanding of the course of AP is still far from complete, limiting treatment options mostly to conservative supportive care. Emerging evidence has pointed to modulation of the immune system for strategic therapeutic development, by mitigating the inflammatory response and severity of AP. In the current review, we have focused on the role of innate immunity in the condition and highlighted therapeutics targeting it for treatment of this challenging disease. ⋯ The current state of knowledge on AP, limitations of presently available therapeutic approaches and the promise of therapeutic implications of innate immune system in AP are discussed.

Kisspeptins are a family of neuropeptides whose identification has become one of the biggest discoveries in reproductive endocrinology during the past decade. Kisspeptins act upstream of GnRH as high-level mediators of the reproductive axis. ⋯ The identification of the kisspeptin signaling pathway has greatly advanced the study of reproductive endocrinology. Building on a large body of animal data, a growing number of human studies have shown that exogenous kisspeptin can stimulate physiological gonadotropin responses in both healthy subjects and those with disorders of reproduction. There is an increasing appreciation that kisspeptin may act as a signal transmitter between metabolic status and reproductive function. Future work is likely to involve investigation of novel kisspeptin analogs and further exploration of role of neurokinin B and dynorphin on the kisspeptin-GnRH axis.
