Abstract
- Abstract: The process of ageing denotes a post-maturational deterioration of cells and organisms with the passage of time, an increased vulnerability to challenges and prevalence of age-associated diseases, and a decreased ability to survive. Causes may be found in an enhanced production of reactive oxygen species (ROS) and oxidative damage and not completed housekeeping, with an accumulation of altered ROS-hypergenerating organelles in older cells. It has been shown that autophagy is the only tier of defence against the accumulation of effete mitochondria and peroxisomes; that functioning of autophagy declines with increasing age and determinates cell and individual lifespan; that autophagy can be intensified by drugs; and that the pharmacological intensification of autophagy may be a big step towards retardation of ageing and prevention and therapy of age-associated diseases including neurodegeneration.
