RESUMEN

Proteins involved in zinc homeostasis may be altered in aging. This phenomenon may lead to zinc deficiency in the peripheral blood and an accumulation of zinc bound to insoluble aggregates at the extracellular level in the brain. Therefore, it should be more correct to talk about aging as a condition associated with zinc dyshomeostasis rather than deficiency. Restoring functional zinc homeostasis in aging people is an attractive field for antiaging research, but requires further knowledge than the current state of the art.
