Abstract
The sensation of pain is associated with increased mortality, but it is unknown whether pain perception can directly affect aging. We find that mice lacking TRPV1 pain receptors are long-lived, displaying a youthful metabolic profile at old age. Loss of TRPV1 inactivates a calcium-signaling cascade that ends in the nuclear exclusion of the CREB-regulated transcriptional coactivator CRTC1 within pain sensory neurons originating from the spinal cord. In long-lived TRPV1 knockout mice, CRTC1 nuclear exclusion decreases production of the neuropeptide CGRP from sensory endings innervating the pancreatic islets, subsequently promoting insulin secretion and metabolic health. In contrast, CGRP homeostasis is disrupted with age in wild-type mice, resulting in metabolic decline. We show that pharmacologic inactivation of CGRP receptors in old wild-type animals can restore metabolic health. These data suggest that ablation of select pain sensory receptors or the inhibition of CGRP are associated with increased metabolic health and control longevity.

Osm-9 and Capsaicin receptor-Related

Locus: CELE_T09A12.3

Wormbase description: ocr-2 encodes a TRPV (transient receptor potential channel, vanilloid subfamily) ion channel; OCR-2 activity is required for several types of sensory transduction including olfaction, osmosensation, mechanosensation, and chemosensation; an OCR-2 fusion protein is expressed in sensory cilia and requires the OSM-9 TRPV channel protein for proper localization; likewise, OSM-9 requires OCR-2 for its cilial localization.

hypothetical protein

Locus: CELE_B0212.5

Wormbase description: osm-9 encodes a TRPV channel homologous to capsaicin receptors; osm-9 is involved in sensory responses to a subset of chemical stimuli and to ASH neuron-mediated osmotic and mechanical stimuli; OSM-9 is also involved in adaptation to volatile odorants and salts; OSM-9 is expressed in a variety of sensory neurons and shows neuron-specific localization to either the cell body or the cilium.
