Harvard Researchers Pioneer Pain-Specific Local Anesthesia from Chili Peppers

The new method exploits a membrane-spanning protein called TRPV1, which is unique to pain-sensing neurons. TRPV1 forms a large channel, where molecules can enter and exit the cell. But a “gate” typically blocks this opening. The gate opens when cells are exposed to heat or the chili-pepper ingredient capsaicin. Thus, bathing pain-sensing neurons in capsaicin leaves these channels open, but non-pain sensing neurons are unaffected because they do not possess TRPV1. “We’re optimistic that this method will eventually be applied
