ATP and Pain

P2XRs Play a Key RoleIn dorsal root ganglion (DRG) neurons, ATP is an important neurotransmitter in nociceptive signaling through P2 receptors (P2Rs) such as P2X2/3R, and adenosine is also involved in anti-nociceptive signaling through adenosine A1R.ENNPs interact with P2XRs to metabolize ATP to AMP in DRGs.
