Adenosine is an endogenous nucleoside generated locally in tissues under conditions of hypoxia, ischemia, or inflammation. It modulates a variety of physiological functions in many tissues including brain and heart.1,2 Adenosine exerts its action via four specific adenosine receptors (also named P1 purinergic receptors): A1-Adenosine receptor (A1AR), A2A-Adenosine receptor (A2AAR), A2B-Adenosine receptor (A2BAR), and A3-Adenosine receptor (A3AR). The various adenosine receptors can be distinguished on the basis of their distinct molecular structures, distinct tissue distributions, and differential selectivity for adenosine analogs.1-4 However, all are integral membrane proteins and members of the G Protein-Coupled Receptor superfamily. They share a common structure of seven putative transmembrane domains, an extracellular amino terminus, a cytoplasmic carboxyl terminus, and a third intracellular loop that is important for binding G proteins.1-3 Expression of A3AR has been reported in brain, kidney, liver, and heart. It plays a role in modulation of cerebral ischemia, asthma, and cell growth. In addition, recent studies have established a cardioprotective role for A3AR.5 Expression of A3AR was reported to be elevated in cancerous tissues as well as in auto-immune inflammatory diseases.6,7 A patent has been filed for the use of A3AR and A3AR agonist as a diagnostic marker for therapeutic treatments of cancer and other diseases. Abgent is pleased to offer a highly specific antibody directed against an intracellular epitope of human A3 Adenosine receptor (A3AR). Anti-A3 Adenosine Receptor antibody (#AG1384) can be used in western blot analysis, as well as immunocytochemical and immunohistocemical applications, and has been designed to recognize A3 Adenosine receptor from human, rat, and mouse samples.
