Formula PSORI-CM01 inhibits the inflammatory cytokine and chemokine release in keratinocytes via NF-κB expression.
International Immunopharmacology 2017 March
Psoriasis is a common chronic inflammatory disease in which T-helper 1(Th1) and T-helper 17(Th17) cells play an important role in its pathology. Formula PSORI-CM01 was a novel formulated Chinese medicine used for psoriasis therapy. It had been demonstrated previously that PSORI-CM01 and serum contained Formula PSORI-CM01 (PCM01CS) could improve psoriasis by inhibiting the epithelial hyperplasia, how PSORI-CM01 affects inflammatory cytokine and chemokine in dermis is still unknown. In this study we found PSORI-CM01 pre-treated 3days before IMQ painting could ameliorated IMQ-induced mice skin lesion as PASI score was apparently reduced. Th1 related cytokine IFN-γ and Th17 related cytokine IL-17/IL-22 was used to induce inflammatory models on human keratinocyte cell line HaCaT in vitro, respectively. PCM01CS significantly reduced IFN-γ induced mRNA expression of IL-6, IL-12 and CXCL-10, reduced IL-6 and CXCL-10 release into HaCaT supernatant. 20ng/ml IL-17/IL-22 co-stimulation significantly upregulated expression of IL-6, IL-8 and CCL20 mRNA expression in HaCaT cells, PCM01CS significantly inhibit these cytokines expression both in mRNA and in protein levels. Finally, PCM01CS could obviously inhibit nuclear NF-κB p65 expression which activated by IFN-γ and IL-17/IL-22 stimulation. Thus, our new findings reveal that Formula PSORI-CM01 may possess therapeutic action on psoriasis by inhibiting inflammatory within skin environments.
