A: Exposure of HCLE cells to 50 ng/mL TNF-α for 7 min (without UVB) resulted in K+ channel activation. Addition of the K+ channel blocker Ba2+ (5 mM) inhibited TNF-α –induced K+ currents. (TNF-α data are mean ± SE of 7 cells). B: Cells incubated with TNF-α for 20 min lost 24% of intracellular K+, compared to 37% lost during a 20 min incubation following exposure to 150 mJ/cm2 UVB. Values marked * differ significantly from control value. (Mean ± SD, n = 8, ANOVA and SNK test, p < 0.05).
