Effects of the corticotropin-releasing factor 1 (CRF1R) antagonist CP154,526 (CP) on cerebro-cortical neuroimmune mRNAs following restraint stress in rats. Overall there was a significant effect among the groups for CCL2 (F(2,16) = 4.00, p < 0.05) with CP failing to block stressed-induction. There also was an effect of treatments for TNFα (F(2,16) = 4.87, p < 0.05) with stress inducing and CP failing to block induction. Finally, as with CCL2 and TNFα, cortical IL-1β effects were significant overall (F(2,16) = 6.34, p < 0.01), but there was no blockade of the stress effect by the drug. * p < 0.05, ** p < 0.01 versus control-vehicle treated rats. Veh = 0.5% carboxymethylcellulose. A, B, and C delineate data for CCL2, TNFα, IL-1β and TLR4 mRNAs, respectively, (n = 5–7 per group).
