Ciliary neurotrophic factor combined with soluble receptor inhibits synthesis of proinflammatory cytokines and prostaglandin-E2 in vitro.

In human peripheral blood mononuclear cells, ciliary neurotrophic factor (CNTF) weakly suppressed endotoxin-induced interleukin (IL)-1 and prostaglandin E2(PGE2). Suppression of PGE2 and IL-8 synthesis was significantly greater (up to 42.6%, P < 0.05) by adding a 10-fold molar excess of soluble CNTF receptor (sCNTFR alpha). In cultured human fibroblasts, CNTF at 12 micrograms/ml did not suppress IL-1 alpha- induced IL-8. However, in the presence of a 10-fold excess of sCNTFR alpha, 300 ng/ml of CNTF suppressed IL-1 alpha- induced IL-8 by 44%. Therefore, sCNTFR alpha can confer to CNTF anti-inflammatory properties in vitro. IL-6 which, like CNTF, utilizes the gp130 signal transducer, possesses similar inhibitory effects. That CNTF and IL-6 share gp130 as a receptor component suggests that gp130 mediates these anti-inflammatory responses.[1]
