PBM regulates pro-inflammatory DNCB-induced cytokines in KCs. KCs were treated with DNCB or vehicle, with or without red (660 nm) or green (520 nm) light illumination (3 J/cm2, 250 s). Pro-inflammatory cytokines gene expression: TNF-α, IL-6, IL-8, and IL-1β, were measured by RT-qPCR 3 and 6 h after DNCB and light treatment. Results are expressed as fold change. Data represent mean ± SEM of 5 independent experiments. Two-Way ANOVA followed by Tukey post hoc test, * p < 0.05; *** p < 0.001 vs. the relative control at 3 h or 6 h; $ p < 0.05; $$ p < 0.01; $$$ p < 0.001 vs. DNCB at 3 h.
