Interleukin-6 stimulates the secretion of adrenocorticotropic hormone in conscious, freely-moving rats
Abstract
In order to assess the effect of interleukin-6 on the hypothalamo-pituitary-adrenal axis, we administered recombinant human interleukin-6 to conscious, freely-moving rats. The intravenous injection of interleukin-6 significantly increased the plasma level of adrenocorticotropic hormone 30 min after the injection in a dose-related manner. Immunoneutralization of corticotropin-releasing hormone blocked the stimulatory effects of interleukin-6 on adrenocorticotropic hormone secretion. These observations suggest that interleukin-6 stimulates the secretion of adrenocorticotropic hormone through the corticotropin-releasing hormone and is possibly involved in the interaction between the neuroendocrine and immune system.
