An Introduction to Purinergic Receptors [PDF]
, 1981 Adenosine 5′-triphosphate (ATP) was primarily considered as an intracellular energy source for many years. However, during the past fifty years purine nucleotides and nucleosides have been shown to have potent extracellular actions on excitable membranes which may be involved in physiological regulatory processes (Berne, 1963; Burnstock, 1972, 1975 ...

Purinergic and Glutamatergic Receptors on Astroglia
2014Astroglial cells express many neurotransmitter receptors; the receptors to glutamate and ATP being the most abundant. Here, we provide a concise overview on the expression and main properties of astroglial glutamate receptors (ionotropic receptors represented by AMPA and NMDA subtypes) and metabotropic (mainly mGluR5 and mGluR3 subtypes) and ...

Purinergic (P2) Receptors in the Kidney
2003Publisher Summary This chapter focuses on renal P2 receptors and their relationship to the renal effects of adenosine triphosphate (ATP). It also focuses on the nonvascular P2 receptors of renal epithelia. The effects of adenosine on renal function, the distribution of its P1 (A 1–3 subtypes) receptors in kidney tissue, and the potential of this ...

Agonists and Antagonists for Purinergic Receptors
2019Membrane receptors that are activated by the purine nucleoside adenosine (adenosine receptors) or by purine or pyrimidine nucleotides (P2Y and P2X receptors) transduce extracellular signals to the cytosol. They play important roles in physiology and disease. The G protein-coupled adenosine receptors comprise four subtypes: A1, A2A, A2B, and A3.

Purinergic receptors in gastrointestinal inflammation
American Journal of Physiology-Gastrointestinal and Liver Physiology, 2008Purinergic receptors comprise a family of transmembrane receptors that are activated by extracellular nucleosides and nucleotides. The two major classes of purinergic receptors, P1 and P2, are expressed widely in the gastrointestinal tract as well as immune cells.

PET Imaging of Purinergic Receptors
2020Over the recent years, interest in the purinergic signaling system has sparked in the field of positron emission tomography (PET). Purinergic receptors play key roles in physiological and pathological processes, although the exact role in these processes is not always fully understood.

Purinergic receptors in auditory neurotransmission
Hearing Research, 2003The effects of ATP (adenosine 5' triphosphate) analogs on gross cochlear potentials and single primary afferent discharge properties were studied by intracochlear perfusion in anesthetized guinea pigs. ATP-gamma-S was most potent, with betagammamethylene-ATP and Bz-ATP being significantly less effective.

Purinergic receptors in psychiatric disorders
Neuropharmacology, 2016Psychiatric disorders describe different mental or behavioral patterns, causing suffering or poor coping of ordinary life with manifold presentations. Multifactorial processes can contribute to their development and progression. Purinergic neurotransmission and neuromodulation in the brain have attracted increasing therapeutic interest in the field of ...

The enteric purinergic P2Y1 receptor
Current Opinion in Pharmacology, 2006Significant recent discoveries have shown that the P2Y(1) purinergic receptor subtype is expressed in the enteric nervous system and at intestinal neuromuscular junctions. Secretomotor neurons, which release vasoactive intestinal peptide at their junctions with intestinal secretory glands, express the P2Y(1) receptor.

Purinergic receptors in embryonic and adult neurogenesis
Neuropharmacology, 2016ATP (adenosine 5'-triphosphate), one of the most ancient neurotransmitters, exerts essential functions in the brain, including neurotransmission and modulation of synaptic activity. Moreover, this nucleotide has been attributed with trophic properties and experimental evidence points to the participation of ATP-activated P2X and P2Y purinergic ...
