The mitogenic response of human peripheral blood lymphocytes to the lectin concanavalin A (conA) is inhibited by micromolar concentrations of CdCl2. This inhibition is partially relieved by an increase in the external Ca2+ concentration (from 0.6 to 2.2 mM). The initial rate of conA-induced 45Ca2+ influx is unaltered by CdCl2, although the level of 45Ca2+ accumulation increases. The basal rate of 45Ca2+ entry is not measurably disturbed by CdCl2 (100 microM). The steady-state efflux of 45Ca2+ and the calmodulin-activated (Ca2+ + Mg2+)-ATPase activity of erythrocyte ghosts are inhibited by CdCl2 (10 microM). Thus, the mechanism behind the Cd2+-induced suppression of the mitogenic response to conA is not due to alteration of mitogen-stimulated Ca2+ influx. We suggest that Cd2+ competes with Ca2+ for intracellular Ca2+-binding molecules, such as calmodulin, essential for the induction of cell proliferation.
