Lead neurotoxicity: exploring the potential impact of lead substitution in zinc-finger proteins on mental health
This critical review focuses on one possible link between the cellular biology of lead and its neurotoxic effects: the link between Pb2+ substitution for Zn2+ in zinc-finger proteins and mental illness in adulthood.

Mutation in HFE gene decreases manganese accumulation and oxidative stress in the brain after olfactory manganese exposure
HFE H67D mutation up-regulates ferroportin, a metal exporter for manganese (Mn) and iron, and reduces Mn accumulation in the striatum after olfactory exposure to Mn, which consequently decreases Mn-induced oxidative stress in the brain.
