1. Exogenous ATP produces acute and localized pain in humans, and P2X receptor agonists elicit acute nociceptive behaviours in rodents following intradermal administration to the hindpaw. The predominant localization of P2X(3) mRNA in sensory neurones has led to the hypothesis

Interleukin (IL)-17-producing CD4(+) T lymphocytes (T(H)17 cells) constitute a subset of T-helper cells involved in host defence and several immune disorders. An intriguing feature of T(H)17 cells is their selective and constitutive presence in the intestinal lamina propria. Here we

Activation of amoeboid microglial cells (AMC) and its related inflammatory response have been linked to the periventricular white matter damage after hypoxia in neonatal brain. Hypoxia increases free ATP in the brain and then induces various effects through ATP receptors.
