After peritoneal macrophages had been exposed to different concentrations of nifedipine (10-120 ng mL-1) there was a significant increase (P less than 0.001) in the percentage of Leishmania donovani infected macrophages compared with controls. Parasite load was also significantly increased (P less than 0.001) in nifedipine-treated, L. donovani infected, BALB/c mice, compared with untreated, infected mice, post-inoculation. Peak chemiluminescence responses were significantly depressed (P less than 0.001) in nifedipine-treated infected mice compared with untreated mice post-inoculation. It is suggested that availability of intracellular calcium is a factor in the defense mechanism of inflammatory cells in L. donovani infections.
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.
