Enhanced expression of inflammatory cytokines in inflammatory acne lesions. Skin was obtained from inflammatory papules and uninvolved areas of facial acne. Tissue specimens were assayed for cytokine mRNA levels using real-time quantitative RT-PCR. The values shown are means, with standard errors indicated by the bars. For each cytokine, mRNA levels were significantly higher in inflammatory acne than in uninvolved control skin (TNF-α, P < 0.05; IL-1β, P < 0.007; IL-8, P < 0.001; IL-10, P < 0.001; n = 8). ▪, uninvolved skin; □, acne lesion.
