摘要：
Interleukin-1-beta (IL-1-beta) induces a dose-dependent increase in the release of corticotropin-releasing factor-41 (CRF) from dispersed rat fetal hypothalamic cells in culture. This release of CRF could be inhibited by the protein kinase C inhibitor H-7, and by the protein kinase A inhibitor IP-20. This suggests that both protein kinase C and protein kinase A-dependent pathways are involved in the response of CRF to IL-1-beta. Dexamethasone also blocked the CRF response to IL-1-beta, indicating that activated glucocorticoid receptors can inhibit the response of CRF to IL-1-beta.
