BACKGROUND: Experiments were conducted to evaluate the contribution of P2X4 receptors to the modulation of neuropathy and their ability to amplify opioid effectiveness.
P2X ion channel receptors and inflammation.
Burnstock, Melbourne, Australia. In Purinergic Signal, Feb 2016
The P2X7 receptor in particular appears to be an essential immunomodulatory receptor, although P2X1 and P2X4 receptors also appear to be involved.
Effect of P2X4R on airway inflammation and airway remodeling in allergic airway challenge in mice.
Ni et al., Daqing, China. In Mol Med Report, Jan 2016
P2X4 receptor (P2X4R) is the most widely expressed subtype of the P2XRs in the purinergic receptor family.
Fatigue sensation and gene expression in trained cyclists following a 40 km time trial in the heat.
White et al., Salt Lake City, United States. In Eur J Appl Physiol, Jan 2016
Both trials resulted in significant post-exercise decreases in metabolite detecting receptors ASIC3, P2X4, TRPV1, and TRPV4; increases in adrenergic receptors α2a, α2c, and β1; decreases in adrenergic β2, the immune receptor TLR4, and dopamine (DRD4); and increases in serotonin (HTR1D) and IL-10 (p < 0.05).
Medicinal chemistry of adenosine, P2Y and P2X receptors.
Müller et al., Bethesda, United States. In Neuropharmacology, Jan 2016
Some of these compounds, including A1 and A3 AR agonists, P2Y1R and P2Y12R antagonists, and P2X3, P2X4 and P2X7 antagonists, are potentially of clinical use in treatment of disorders of the nervous system, such as chronic pain, neurodegeneration and brain injury.

Liu et al., Miami, United States. In J Cell Physiol, Jan 2016
Within the past few years, the characterization of crystal structures of the zebrafish P2X4 receptor in its closed and open states has provided critical insights into the mechanisms of ligand binding and channel activation.
ATPergic signalling during seizures and epilepsy.
Henshall et al., Dublin, Ireland. In Neuropharmacology, Dec 2015
The ATP-gated purinergic receptor family is expressed throughout the brain and is functional on neurons and glial cells.
Differential expression of ATP-gated P2X receptors in DRG between chronic neuropathic pain and visceralgia rat models.
Li et al., Wuhan, China. In Purinergic Signal, Dec 2015
We found that except P2X2 and P2X3, the expression levels of P2X1 and P2X5 receptors increased in neuropathic pain while those expression levels of P2X4, P2X6, and P2X7 receptors increased in visceral pain.

Imaging P2X4 receptor lateral mobility in microglia: regulation by calcium and p38 MAPK.
Khakh et al., Los Angeles, United States. In J Biol Chem, 2012
lateral mobility is P2X subunit- and cell-specific, increased in an ATP activation and calcium-dependent manner, and enhanced in activated microglia by the p38 MAPK pathway that selectively regulates slowly mobile receptors
Regulation of P2X7-dependent inflammatory functions by P2X4 receptor in mouse macrophages.
Kojima et al., Noda, Japan. In Biochem Biophys Res Commun, 2012
co-expression of P2X4 receptor with P2X7 receptor enhances P2X7-mediated inflammation through both facilitation of release of cytokines and suppression of autophagy.
P2X4 receptors influence inflammasome activation after spinal cord injury.
Lacroix et al., Miami, United States. In J Neurosci, 2012
