This brief review will describe recent findings on the direct interaction of metal ions with ionotropic γ-aminobutyric acid (GABAA) and glutamate receptors, the main inhibitory and excitatory neurotransmitter...
We have previously reported that nickel acetate (Ni2+), a well-known human carcinogenic agents, differentially affected apoptosis in two different airway epithelial cell lines derived from the human respiratory tract (A549 and Beas-2B, respectively), suggesting a potential involvement of epidermal growth factor receptor (EGFR)/Neu receptors in mediating this effect. Since ErbBs are closely associated...
