Vandellia cordifolia (V. cordifolia) used for treatment inflammation in traditional Chinese medicine was selected for immunopharmacological activity test. The effects of V. cordifolia extracted fractions on human mononuclear cells (HMNC) proliferation were determined by tritiated thymidine uptake. The results indicated that VC-ME fraction suppressed HMNC proliferation activated with phytohemagglutinin (PHA) and stimulated cell cycle progression was arrested at the G0/G1 stage. The inhibitory mechanisms may involve the blocking of interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) production, since VC-ME suppressed IL-2 and IFN-gamma production of HMNC in a dose-dependent manner. Therefore, it is suggested that immunomodulatory agents are contained in V. cordifolia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
