  • Abstract: <p>The most environmentally abundant toxic metals/metalloids (arsenic, cadmium, lead, and mercury) are each known to produce cell injury in the kidney but the molecular mechanisms underlying these events are now being elucidated. It is clear that the nephrotoxicity of these agents is due, in part, to the fact that urinary elimination is a major route of excretion from the body. The role(s) of molecular factors such as metal-binding proteins, inclusion bodies, and cell-specific receptorlike proteins that appear to influence renal tubule cell expression, have attracted increased interest as determinants that modulate cell populations as special risk for toxicity and renal cancer. The future of mechanistic toxicology studies with regard to how and why only certain renal cell populations become targets for toxicity from these metals/metalloids and other less common inorganic nephrotoxicants must focus on the molecular handling of these agents by target cell populations.</p>
