Abstract
Natural killer (NK) cell activity of mice given a single injection of manganese chloride (MnCl2) was significantly enhanced as measured in a 4-hr in vitro 51Cr release assay. Enhanced activity persisted for several days after injection. This cytotoxic activity was associated with nonadherent spleen cells and was completely eliminated by injecting MnCl2-treated mice with anti-asialo GM1 serum. Manganese chloride enhancement of NK cell activity appeared to be mediated by interferon (IFN). Low levels of IFN were detected in the serum of mice as early as 4 hr after MnCl2 injection. Rabbit anti-mouse IFN alpha, beta but not anti-mouse IFN gamma completely eliminated the MnCl2-enhanced NK cell activity in the spleens of mice. The observed enhancement of NK cell activity by MnCl2 is similar to that reported for more complex molecules that act by inducing IFN production.
