Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic
signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors …

Extracellular purines (adenosine, ADP, and ATP) and pyrimidines (UDP and UTP) are
important signaling molecules that mediate diverse biological effects via cellsurface …

P2X receptors are membrane ion channels that open in response to the binding of
extracellular ATP. Seven genes in vertebrates encode P2X receptor subunits, which are 40 …

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 …

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 …

Cadmium is a common environmental pollutant that accumulates in the bone and kidneys
and causes severe health and social problems. However, the effects of Cd on the …

ATP acts as a humoral mediator to control cell function extracellularly. The receptors that
mediate the actions of ATP belong to two classes, the metabotropic P2Y receptors and the …

There are seven P2X receptor cDNAs currently known. Six homomeric (P2X1, P2X2, P2X3,
P2X4, P2X5, P2X7) and three heteromeric (P2X2/P2X3, P2X4/P2X6, P2X1/P2X5) P2X …

The charge of this invited review is to present a convincing case for the fact that cells release
their ATP for physiological reasons. Many of our “purinergic” colleagues as well as …

Abstract ATP-gated P2X receptors are trimeric ion channels that assemble as homo-or
heteromers from seven cloned subunits. Transcripts and/or proteins of P2X subunits have …
