title: Role of endotoxin and interleukin-1 in modulating ACTH, LH and sex steroid secretion.
abstract: We have shown that the endotoxin LPS acted both at the level of the brain and the gonads to stimulate the hypothalamic-pituitary-adrenal, and inhibit the hypothalamic-pituitary-gonadal, axis. Exogenously administered IL-1 mimics most of the effects of LPS on pituitary activity. In addition, antibodies against IL-1 receptors can interfere with LPS-induced ACTH secretion. These results suggest that at least part of the ability of LPS to alter endocrine functions appears to depend upon endogenous interleukin-1.
