- Knockout of TMEM63B reduces heat sensitivity
Removing the TMEM63B channel from dorsal root ganglion neurons significantly reduced heat sensitivity and raised the temperature required to trigger action potentials.
- Field
- the brain and neuroscience
- What they did
- Researchers discovered that the TMEM63B channel in dorsal root ganglion neurons contributes to the sensation of heat rather than mechanical stimuli. Removing this channel raised the temperature threshold required to trigger nerve responses.
- Why it matters
- This finding helps clarify the mechanisms of thermosensation and could inform treatments for conditions involving altered temperature sensitivity.
