Apoptosis in dopaminergic neurons of the human substantia nigra during normal aging.

Abstract

Morphological and biochemical alterations have been described in neurons of the aged human brain. However, the cell death process associated with neuronal senescence remains to be elucidated. Apoptosis and autophagic degeneration, two modes of programmed cell death described in embryogenesis and tissue renewal in adult, have been observed in nigral… (More)
