COVER This genetically modified mouse lacks the receptor for capsaicin (the pungent ingredient in chili peppers) and no longer avoids the spicy Habanero pepper. These mice also exhibit a reduction in their ability to detect protons or heat under normal or pathophysiological conditions, illustrating a requirement for the capsaicin receptor in detecting diverse modalities of pain-producing stimuli.
