Progress of Anti-aging Drugs Targeting Autophagy

Senescence is a progressive process of degeneration that occurs when cells and organisms mature. Many studies have shown that autophagy is closely related to senescence. Autophagy gradually decreases with the senescence activity of cells, and vice versa. Therefore, moderate autophagy can protect the body and inhibit cell senescence. The inactivation of genes encoding nematode insulin-like tyrosine kinase receptor (daf-2) inhibited the activity of type I PI3K (age-1), Akt molecules (akt1, akt2), PDK (pdk-1), and TOR, and increased the lifespan and autophagy of Caenorhabditis elegans.
