Chronic stimulation of the pituitary-adrenal axis in rats by interleukin-1 beta infusion: in vivo and in vitro studies.

abstract：:In primary cultures of sheep pituitary cells extracellular nucleotides stimulated rapid increases in inositol tris- and bisphosphate, accompanied by intracellular Ca2+ mobilization. A similar stimulation of inositol phosphate production by extracellular nucleotides was observed in rat and baboon pituitary cells. The i...
