Description:
ADORA2B encodes an adenosine receptor that belongs to the G protein-coupled receptor superfamily. Adenosine is a purine nucleoside produced by the catabolism of S-adenosylhomocysteine (SAH) and adenosine monophosphate (AMP) molecules. It is a ubiquitous signalling molecule with essential functions across all organ systems. Under conditions of stress, such as hypoxia or ischemia, the intracellular concentration of adenosine increases. ADORA2B requires higher than the physiologic concentration of adenosine for activation. Downstream effects of ADORA2B signalling include tissue adaptation to injury, increased ischaemia tolerance and attenuation of acute inflammation. Also, ADORA2B interacts with netrin-1, a neuronal guidance molecule, to dampen inflammatory cell accumulation during hypoxia. Notably, the persistence of adenosine signalling has been shown to result in excessive inflammatory tissue damage and in the development of severe diseases, such as acute lung, liver or kidney injury. Polymorphisms in this gene associated with pulmonary hypertension risk in sickle cell disease patients.
