摘要：

Terrestrial snails tolerate elevated concentrations of cadmium and copper, accumulating both metals in their soft tissues1. The snails are able to inactivate the toxic cadmium while meeting their metabolic requirement for copper. Here we report evidence for the metabolic discrimination between the two metals based on the existence of distinct metallothionein isoforms, one dedicated to cadmium detoxification and another to copper regulation.
