Anti-inflammatory activity of a Vernonia˙cinerea methanolic extract in vitro

Aurasorn˙Saraphanchotiwitthayaa,b,*, Pattana˙Sripalakitb,c

ABSTRACT:     Vernonia cinerea Less. (Asteraceae) is a herbaceous plant commonly found in SE Asia. Different parts of V.˙cinerea have been used in various folklore medicine applications, including reducing inflammation and detoxification. This study investigates the effects of V.˙cinerea methanolic extract on the mouse immune system in vitro. Cytokine detection of ConA-stimulated splenocytes using ELISA, mitogen-induced splenocyte proliferation, and phagocytic activity were assayed. The results show that the extract shifted the Th1/Th2 balance towards a Th2 type response. Additionally, Th1- and Th2-related cytokine production correlated with lymphocyte proliferation by selective activation of T-cells into Th2-cells and suppression of Th1-cell proliferation. Our results confirmed the traditional applications of V.˙cinerea on immune-related remedies and anti-inflammation, suggesting a potential therapeutic application of this plant in the treatment of diseases associated with Th1-related cytokine production and inflammation.
