Abstract

One characteristic feature of the aged central nervous system (CNS) is neuron loss. Programmed cell death (PCD) has been implicated in neuronal death during development and may be involved in a number of age-related neurodegenerative diseases of the CNS. Cell death in the aging cerebral cortex was investigated in the present morphometric and immunohistochemical study of rat frontal cortex by detection of bcl-2 as the factor preventing PCD. The results were interpreted in the light of the bioenergetic features of aged motoneuron cells. Our results showed that 1) bcl-2 does not influence neuronal survival, and ii) the presence in aging frontal cortex of minor cellular morphometric and bioenergetic modifications, confirming the difference between normal aging and neurodegenerative disease.
