| Outline of Final Research Achievements |
AMP activated protein kinase (AMPK) is a widely expressed intracellular energy sensor that monitors and modulates energy expenditure. AMPK is activated in response to ATP consumption, and upon activation, AMPK phosphorylates a broad range of downstream targets, which results in a reduction in energy usage and an increase in energy production. Transient receptor potential ankyrin 1 (TRPA1) channel is a widely recognized chemical and thermal sensor that plays vital roles in pain transduction.
Here, we discovered a functional link between AMPK and TRPA1 in dorsal root ganglion (DRG) neurons, in which AMPK activation rapidly inhibit TRPA1 channel activity within minutes. These observation demonstrated an important role and the molecular mechanism of AMPK in pain generation.
