Reciprocal co-regulation of IL-13- and IL-17A-induced genes occurs in vitro. Real-time PCR analysis of C3 (A), Il13ra2 (B), Cebpd (C), and Lcn2 (D) expression in NIH/3T3s stimulated with IL-13, IL-17A, or both cytokines over 24 hours. ## and ### indicate P<0.01 and <0.001 vs Medium. +, ++, and +++ in indicate P<0.05, <0.01, and < 0.001 vs IL-13 (A, B) or IL-17A (C). Mean + SEM of 4-8 replicates per condition shown. Results show 1 of 3 independent experiments.
