Aging cells accumulate damaged and misfolded proteins through a functional decline in their protein homeostasis (proteostasis) machinery, leading to reduced . We propose that the collapse of proteostasis represents an early molecular event of aging that amplifies protein damage in age-associated. Proteostasis, a portmanteau of the words protein and homeostasis, is the concept that there are Cellular proteostasis is key to ensuring successful development, healthy aging, resistance to 2 Signaling events in proteostasis . capacity, proteostatic collapse occurs and chaperone production is severely impaired.
