Description In the extracellular space, ecto-5′-nucleotidase (CD73) dephosphorylates adenosine triphosphate (ATP) to produce adenosine. Adenosine has four receptors namely A1R, A2AR A2BR and A3R. Adenosine plays a key role in the osteogenic differentiation. A1R induces osteoclast differentiation and A2AR induces osteoblast differentiation. Application Adenosine has been used: as a supplement in embryonic type culture medium for in vitro osteogenic differentiation for evaluation of its effect on cell survival by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT assay) and cell proliferation by 3H-thymidine incorporation assay in multi drug resistant glioblastoma stem-like cells (GSCs), and as a standard in high performance liquid chromatography (HPLC). as a constituent in collagenase solution for the collagenase digestion of mice fat tissue. Biochem/physiol Actions Endogenous neurotransmitter at adenosine receptors. Cardioprotective effects may relate to activation of A1 adenosine receptors. The antiplatelet and anti−inflammatory actions of adenosine appear to be mediated via the A2 adenosine receptor. In contrast, adenosine appears to be a pro-inflammatory mediator in asthma and chronic obstructive pulmonary disease (COPD). Endogenous neurotransmitter.
