Abstract

The expression of cholecystokinin (CCK) mRNA in neuroendocrine corticotropin-releasing hormone (CRH) neurons of the hypothalamic paraventricular nucleus (PVN) of male rats was examined 8 h following an acute immune challenge by intraperitoneal lipopolysaccharide (LPS, 250 μg/kg). Both quantitative, macroautoradiographic, single-label radioactive in situ hybridization histochemistry (ISHH) and qualitative dual-label ISHH were performed. Compared to controls, LPS-injected rats displayed increased (185%) parvicellular CCK mRNA expression levels, occurring in a majority (70%) of CRH neurons as revealed by dual-label ISHH.
