Nerve protein shown crucial to sensations of pain from heat, injury
...ponses to a range ofmoderately unpleasant heat and mechanical
stimuli to the paw. Normal micewithdraw from these stimuli. In contrast, mice lacking theVR1 gene respondedmore slowly to the heat stimulus. Thus VR1 is critical for heat, but notmechanical pain sensitivity. Also, the mice didn't hesitate to drink wa...
