Effect of indirubin on the expression of proinflammatory cytokines in keratinocytes

Objective： To investigate the effect of indirubin on the expression of proinflammatory cytokines in HaCaT cells, and to elucidate the mechanisms of Diqing ointment in the treatment of psoriasis.Methods:The human immortalized keratinocyte cell line, HaCaT cells, were used to observe the changes in the expression levels of IL-1β, IL-6, and TNF-α in HaCaT cells after treatment with different concentrations of indirubin. HaCaT cells were divided into 4 groups. The secretion levels of IL-1β, IL-6, and TNF-α in the culture supernatants were detected by enzyme-linked immunosorbent assay ELISA, and the expression levels of IL-1β, IL-6, and TNF-α mRNA were detected by real-time PCR (RT-qPCR). Results:Expression levels of both mRNA and protein of IL-1β, IL-6, and TNF-α were significantly and dose-dependently decreased after treatment with indirubin. Conclusion:Indirubin, the main component of Qingdai ointment, can lower expression levels of pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α in keratinocytes, leading to the improvements of psoriasis.
