Fruit flies can taste and avoid food contaminated with a bacterial toxin using the same channel protein that functions in humans as sensor of noxious chemical stimuli.
Electrophysiological experiments, Ca2+ imaging, and behavioral studies in mice identify the TRPM3 ion channel as a novel target of G-protein βγ subunits.
Two natural cooling agents activate the cold-activated channel TRPM8 via two opposite mechanisms, evoking distinct electrical responses in cold-sensitive neurons.
A pain-relaying ion channel on a hypersensitive population of sensory neurons can instead elicit sensations of itch in both fish and mice when directly activated, providing a novel model of itch transduction.

The activation and membrane localization of the broadly-tuned noxious chemosensory cation channel TRPA1 are regulated by direct interactions with cholesterol via CRAC motifs in transmembane segments 2 and 4.
A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.
