"The initial pain-dulling sensation occurs when capsaicin activates heat-sensing transient receptor potential vanilloid 1(TRPV1) ion channels on sensory neurons. Prolonged stimulation with the compound results in desensitization of these neurons. “This is one of the underlying mechanisms of capsaicin’s numbing effect, but TRPV1 is a heat sensor, so how it affects mechanical pain was not known,” said Tibor Rohacs, an associate professor of pharmacology and physiology at Rutgers New Jersey Medical School, who led the study. Rohacs and his colleagues uncovered a link between the heat-stimulating function of capsaicin and its ability to relieve mechanical pain including neuralgia (pain from damaged nerves), neuropathy, and muscle and joint pain. Capsaicin’s activation of TRPV1 ion channels in turns inhibits mechanical force-sensing ion channels called Piezo1 and 2 by depleting phospholipid signaling molecules, phosphoinositides, in the cell membrane. “What is unique in this study is how one kind of channel regulates the activity of another,” said Tamas Balla, a signal transduction researcher at the National Institutes of Health who previously collaborated with Rohacs but was not part of the current study. “I believe that this is the first example of ion channel cross-talk mediated by phospholipids,” Balla added." - Todd Hoff
