Function
Adenosine A2A receptor (A2AR) is one of the G protein-coupled receptors. The protein uses adenosine as the preferred endogenous agonist and is involved in increasing intracellular cAMP levels.
Disease
A2AR antagonists are being tested in the treatment of Alzheimer's Disease.
Relevance
A2AR is responsible for regulating myocardial blood flow. It is involved in cerebral and renal blood flow, immune function, pain regulation and sleep. For details see G protein-coupled receptor.
