- adj. Pertaining to thermosensation.
Sorry, no etymologies found.
Specifically, the authors suggest that at high temperature, the worm's thermosensory neurons produce a signal that stimulates expression of the daf-9 gene, which produces a steroid hormone that extends lifespan.
C. elegans has been known to have thermosensory or heat-sensing neurons, which allow the worms to move towards temperatures they associate with food.
The data suggest that these thermosensory neurons affect lifespan at warm temperature by changing the activity of a steroid signaling pathway, which in turn affects longevity, according to the paper.
If the "chemical reaction" theory were accurate, worms at a constant hotter temperature would age at the same fast rate, whether their thermosensory neurons perceived the heat or not.
The researchers propose that this thermosensory system allows
"In sum," the researchers wrote, "TGI was reduced only when thermosensory and tactile information from all three fingers was fully integrated.
