Baicalin is the main flavonoid from the roots of an important medicinal plant, Scutellaria baicalensis, which shows a variety biological activities. Psoriasis is a chronic immune-mediated inflammatory disease that affects the skin. The unmet need of psoriasis is that many patients do not respond adequately to available clinical treatment. In this study, we found that baicalin showed inhibited dermal inflammation in a murine model of psoriasis via topical application of imiquimod. After a 5-day topical imiquimod application, baicalin or the control vehicle cream was to applied to the lesions of BALB/c mice for a further 4 days. The erythema, scaling, and thickness of the epidermal layer significantly improved in the baicalin-treated mice. The levels of interleukin-17A, interleukin-22, interleukin-23, and tumor necrosis factor in the skin significantly decreased after baicalin treatment. Baicalin also inhibited imiquimod-induced interleukin-17A production in skin draining lymph node cells. The infiltration of γδ T cells into the skin lesions induced by imiquimod was also suppressed after baicalin treatment. These results suggest that baicalin inhibited skin inflammation through the inhibition of the interleukin-17/interleukin-23 axis in a murine model of psoriasis. [ABSTRACT FROM AUTHOR]

Multiple sclerosis is a chronic inflammatory and autoimmune disease of the central nervous system that affects more than 2.5 million people worldwide. Experimental autoimmune encephalomyelitis is a murine autoimmune disease used to studymultiple sclerosis. Parthenolide, a natural sesquiterpene lactone found in Tanacetum parthenium L., is known for its strong anti-inflammatory activity. Herein, we have investigated the in vitro immunomodulatory effects of parthenolide on cytokine production and nitric oxide in cultured cells from myelin oligodendrocyte glycoprotein 35-55 amino acid peptide mice. Experimental autoimmune encephalomyelitis was induced in C57BL/6 mice with myelin oligodendrocyte glycoprotein 35-55 amino acid peptide, and parthenolide was isolated from T. parthenium. Splenocytes and peritoneal cells were obtained from experimental autoimmune encephalomyelitis- induced mice and incubated with parthenolide (1, 5, and 20 µM). After in vitro treatment with parthenolide, supernatants were collected, and nitric oxide and cytokines were measured. The results suggested that parthenolide may regulate the activity of Th17 and Th1 cells,mainly by decreasing IL- 17, TNF-α, and interferon gamma production. This modulation may be related to the lower levels of IL-12p40 and IL-6 after treatment with parthenolide. It was shown, for the first time, that parthenolide presents in vitro immunomodulatory effects on inflammatory mediators produced by cells from experimental autoimmune encephalomyelitis-induced mice.
