The known seven mammalian receptor subunits (P2X1–7) form cationic channels gated by
ATP. Three subunits compose a receptor channel. Each subunit is a polypeptide consisting …

The vagus nerve is an indispensable body-brain connection that controls vital aspects of
autonomic physiology like breathing, heart rate, blood pressure, and gut motility, reflexes …

The carotid body (CB) is the main peripheral chemoreceptor for arterial respiratory gases O2
and CO2 and pH, eliciting reflex ventilatory, cardiovascular, and humoral responses to …

The discovery of the sensory nature of the carotid body dates back to the beginning of the
20th century. Following these seminal discoveries, research into carotid body mechanisms …

Mammalian ATP-gated nonselective cation channels (P2XRs) can be composed of seven
possible subunits, denoted P2X1 to P2X7. Each subunit contains a large ectodomain, two …

Extracellular adenosine 5′ triphosphate (ATP) is a widespread cell-to-cell signaling
molecule in the brain, where it activates cell surface P2X and P2Y receptors. P2X receptors …

In 1929 Drury and Szent-Györgyi published a seminal paper describing the potent actions of
adenine compounds. Some decades later, adenosine 5'-triphosphate (ATP) was proposed …

Purinergic neurotransmission, involving release of ATP as an efferent neurotransmitter was
first proposed in 1972. Later, ATP was recognised as a cotransmitter in peripheral nerves …

Taste receptor cells detect chemicals in the oral cavity and transmit this information to taste
nerves, but the neurotransmitter (s) have not been identified. We report that adenosine 5 …

P2X receptors are membrane cation channels gated by extracellular ATP. Seven P2X
receptor subunits (P2X1-7) are widely distributed in excitable and nonexcitable cells of …
