"Discovery of Cold Sensation Protein Unlocks New Research Potential"

Researchers have identified GluK2 as the key protein responsible for enabling mammals to sense cold temperatures, filling a long-standing gap in sensory biology. The absence of GluK2 specifically impairs responses to noxious cold in mice, while responses to other temperatures remain unaffected. This discovery offers potential therapeutic targets for addressing abnormal cold sensations in various medical conditions, potentially enhancing patient well-being.
