Lipopolysaccharide modulation of eicosanoid and corticotrophin-releasing hormone release from rat hypothalamic explants and astrocyte cultures in vitro: evidence for the involvement of prostaglandin E2 but not prostaglandin F2 alpha and lack of effect of nerve growth factor.
Bacterial lipopolysaccharide (LPS) and prostaglandins (PG) E2 and F2 alpha are putative activators of the hypothalamo-pituitary-adrenal axis. Certain of the biological effects of LPS may be mediated by cytokines such as interleukin-1 beta (IL-1 beta), while IL-1 beta itself may operate via induction of the prostaglandins and/or nerve growth factor (NGF). As IL-1 beta stimulates the release of corticotrophin-releasing hormone (CRH) from acute rat hypothalamic explants directly, the effects of ...Expand abstract
