How communication between tissues in C. elegans helps maintain protein balance and influences aging

Understanding inter-tissue communication in proteostasis regulation may provide insights into combating aging.

• Aging is associated with a decline in protein homeostasis, leading to the accumulation of misfolded proteins in cells.
• The proteostasis network helps protect cells from the harmful effects of protein aggregates by activating stress response and degradation mechanisms.
• Longevity pathways, such as those involving insulin-like signaling, are influenced by signaling between tissues like the nervous system and intestine.
• Cell nonautonomous signaling may enhance lifespan and resilience to stress while reducing the buildup of harmful protein aggregates.
• Discoveries in the invertebrate model C. elegans have significantly contributed to understanding organismal proteostasis and its regulation.
• Research in mammals is necessary to further validate findings from C. elegans and develop potential therapies targeting proteostasis pathways.
