CO2 enhances HDE stimulated cytokine expression in BAL. BAL fluid was tested by ELISA for (a) IL-6 and (b) KC. HDE instillation induces both cytokines. Increasing CO2 levels (5000 and 7500 ppm) in HDE-treated mice significantly increased production of both cytokines vs ambient air (air). Bar graphs represent standard deviation with error bars shown (N = 5-8 mice/group). Statistical significance denoted by asterisks (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001)
