To examine the effect of interleukin-1 (IL-1) on CRF and POMC gene expression, recombinant human IL-1 alpha and -beta were ip injected in rats. The plasma ACTH level showed a dose-related increase at 2 h after the injection of 0.5 and 2 micrograms IL-1 alpha and -beta, and also showed a sustained increase from 1 h until 5 h after the injection of 2 micrograms of IL-1 beta. CRF contents in the medial basal hypothalamus and ACTH contents in the anterior pituitary (AP) decreased at 2 h after the injection of 2 micrograms of IL-1 alpha and -beta, and such decreased levels were maintained until 5 h after the injection of 2 micrograms of IL-1 beta. The levels of CRF mRNA in the hypothalamus and POMC mRNA in AP significantly increased 3 h after the injection of 2 micrograms IL-1 alpha and -beta, and these levels were still higher at 5 h after the injection of 2 micrograms of IL-1 beta compared with those of the control. There was no significant change in the ACTH content and POMC mRNA levels in the intermediate-posterior pituitary or the hypothalamus or in the CRF contents and CRF mRNA levels in the cerebral cortex. These results indicate that acute administration of IL-1 alpha and -beta stimulates gene expression of hypothalamic CRF and CRF release, which causes the stimulation of ACTH release and POMC gene expression in AP.
