  • Abstract
  • Look Inside

The success of the clone sheep totally changed the established idea of irreversibility and progressiveness of aging. Even a complicated brain can be regenerated from a nucleus of a mature somatic cells. The aging is characterized by the decrease of both activity and number of cells, which are also found in the aging of brain. The decrease in the activity is partly caused by mitochondrial DNA mutation, but mainly by the aging of the nucleus. The decrease of neuron is caused by apoptosis which may be prevented by nerve trophic factors. In addition, the roles played by telomere, insoluble aggregates and chaperone are also discussed.
