Release of ATP in the ventral medulla during hypoxia in rats: role in hypoxic ventilatory response [PDF]
P2X2 receptor subunits of the ATP-gated ion channels are expressed by physiologically identified respiratory neurons in the ventral respiratory column, implicating ATP in the control of respiratory activity.

Abstract Epilepsy affects approximately 1% of the population worldwide, and although medications are effective in the majority of cases, seizures persist in approximately 30% of patients. Despite the effort to develop new antiseizure drugs, the rate of pharmacoresistance in patients has not diminished over the past 3 decades. There is thus a real unmet

Emerging key roles for P2X receptors in the kidney [PDF]
P2X ionotropic non-selective cation channels are expressed throughout the kidney and are activated in a paracrine or autocrine manner following the binding of extracellular ATP and related extracellular nucleotides. Whilst there is a wealth of literature

Spinal cord injury (SCI) is a major cause of paralysis with no current therapies. Following SCI, large amounts of ATP and other nucleotides are released by the traumatized tissue leading to the activation of purinergic receptors that, in coordination ...

The adenylyl cyclase (AC) Rv1625c from M. tuberculosis is a monomeric progenitor of the nine pseudoheterodimeric mammalian AC isoforms. The hexahelical membrane anchor of Rv1625c serves as an inhibitory receptor for fatty acids, particularly oleic acid. One ligand binds into each monomer of the active Rv1625c dimer.

Purinergic receptors and gastrointestinal secretomotor function [PDF]
Secretomotor reflexes in the gastrointestinal (GI) tract are important in the lubrication and movement of digested products, absorption of nutrients, or the diarrhea that occurs in diseases to flush out unwanted microbes. Mechanical or chemical stimulation of mucosal sensory enterochromaffin (EC) cells triggers release of serotonin (5-HT) (among other ...

Possible neuroprotective role of P2X2 in the retina of diabetic rats
Background Purinergic receptors are expressed in different tissues including the retina. These receptors are involved in processes like cell growth, proliferation, activation and survival. ATP is the major activator of P2 receptors. In diabetes, there is

Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,
