IL-6 expression after CPS and/or UVB exposure on HaCaT cells (A) and BJ cells (B). a denotes statistically significant difference from control (cells not treated with CPS nor UVB), b denotes statistically significant difference between CPS and UVB treated cells, as compared to UVB treatment alone. Mean ± SD (n = 3). P < 0.05. CPS, chlorpyrifos
