Effects of PLG on IgE and pro-inflammatory cytokines in DNCB-induced mice. a, b Serum levels of IgE and TNF-α were quantified by ELISA. c–e Production of TNF-α, IL-6, and IL-13 was determined by real-time RT-PCR. Data represent the mean ± SEM. n = 10. ^###P < 0.01 vs. Normal group; ^*P < 0.05, ^**P < 0.01 and ^***P < 0.001 vs. DNCB-induced group
