1. Systemic regulation of mitochondria by germline proteostasis prevents protein aggregation in the soma of C. elegans.

Protein aggregation causes intracellular changes in neurons, which elicit signals to modulate proteostasis in the periphery. Beyond the nervous system, a fundamental question is whether other organs also communicate their proteostasis status to distal tissues. Here, we examine whether proteostasis...
