| 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 [1-2]. |

| General Comments |
| P2X6 is largely retained in the endoplasmic reticulum and fails to exit as a homopolymer, although it may do as a heteropolymer (with P2X2 or P2X4, and with both). However, enhanced glycosylation of P2X6 may improve trafficking of P2X6 homopolymers and can result in functional ATP-activated receptors [6-7,10]. |
