    Abstract:
    This article describes the evaluation of immunomodulatory activity of Mollugo verticillata L. (Molluginaceae), a weed plant common in warm and/or wet regions of the American continent. Nitric oxide (NO) release was evaluated in mice peritoneal cell cultures treated in vivo using the ethanolic extract of M. verticillata with and without BCG. The plant extract showed immunostimulatory activity when peritoneal cells were stimulated in vitro with BCG antigen only. However, mice peritoneal cells treated with M. verticillata plus BCG showed a drastic reduction in NO production when they received the additional stimulus in vitro with BCG. Ethanolic extracts of M. verticillata could directly increase NO release by peritoneal cells, but suppress the immune response of these cells when treated with BCG antigen and Mycobacterium tuberculosis whole antigen (TB). Preliminary phytochemical tests allowed the detection of quercetin and triterpenoid glycosides in the ethanolic extract of M. verticillata, and those compounds are probably responsible for the effect of this plant material on the immune system.
