title: Vanadium carcinogenic, immunotoxic and neurotoxic effects: a review of in vitro studies.
abstract: Deleterious health effects induced by inorganic vanadium compounds are linked with carcinogenic, immunotoxic and neurotoxic insults. The goal of this review is to provide a summary of mammalian cell culture studies (from the 1990s to most recent) looking into the mode of the above-mentioned adverse actions of vanadium. Regarding the carcinogenicity potential, the key cell-based studies have evidenced the ability of vanadium to induce genotoxic lesions, cell morphological transformation and anti-apoptotic effects in a certain type of cells. Two contradictory effects of vanadium on the immune functions of cells have been observed in cell culture studies. The first effect involves reduction of cell immune responses such as vanadium-dependent inhibition of cytokine-inducible functions, which may underlie the mechanism of vanadium-induced immunosuppression. The second one involves stimulation of immune activity, for example, a vanadium-mediated increase in cytokine production, which may contribute to vanadium-related inflammation. So far, an in vitro evaluation of vanadium neurotoxicity has only been reported in few articles. These papers indicate probable cytotoxic mechanisms resulting from exposure of neurons and glial cells to vanadium. In summary, this literature review collects in vitro reports on adverse vanadium effects and thus provides vanadium researchers with a single, concise source of data.
