Role of Calcium Channels in Heavy Metal Toxicity

The role of voltage-dependent Ca channels (VDCC) in the merane permeation of two toxic metals, lead (Pb) and cadmium (Cd), was studied in mammalian cells. Both metals interact with Ca-binding sites, but, while Cd influx appears to occur mainly through the same pathways as Ca, Pb is also rapidly taken up by different passive transport systems.
