Soma to neuron communication links stress adaptation to stress avoidance behavior.

ABSTRACT: In multicellular organisms, signaling from the nervous system to the peripheral tissues can activate physiological responses to stress. Here, we show that inter-tissue stress communication can also function in reverse, i.e. from the peripheral tissue to the nervous system. osm-8 mutants, which activate the physiological osmotic stress response in the C. elegans skin, also exhibit defective osmotic avoidance (Osm) behavior, via a direct and specific effect on ASH osmosensory neuron excitability. Both osm-8 and the Patched-related gene ptr-23 , mutations in which suppress all osm-8 phenotypes, function in the hypodermal lysosomes to regulate both physiology and behavior. Unbiased lipidomics shows that osm-8 leads to a ptr-23 -dependent elevati
