| Immunopharmacology Comments |
| P2X ligand-gated ion channels elicit pro-inflammatory immune responses upon activation by extracellular ATP that acts as a DAMP when released from damaged or infected cells [4-5]. |

| General Comments |
|
The human P2X5 subunit exists as 3 alternatively spliced isoforms (A, which is tabulated above; B, NP_778255 - 397 aa and C, NP_778256 - 178 aa). Of all the functional P2X receptors, only P2X5 homopolymer is unregulated by intracellular PIPn [1-2]. |
