Interleukin-1 beta specifically stimulates nitric oxide production in the hypothalamus

Life Sci. 1996;58(25):PL373-7. doi: 10.1016/0024-3205(96)00238-x.

Abstract

In previous experiments we have shown the role of nitric oxide (NO) in basal and interleukin-1 beta (IL-1 beta)-induced CRH and ACTH release in vitro. Now, we have studied the possible production of NO from hypothalamic cell cultures, particularly after IL-1 beta stimulation or L-NOArg inhibition, by high performance liquid chromatographic (HPLC) assay of L-citrulline production, adding further evidence for a role of NO in IL-1 beta activity in the hypothalamus.
