Synthesis pass · prose summary of the discoveries below

ADORA2B is a low-affinity G protein-coupled adenosine receptor that functions as a master tissue-protective signal transducer during hypoxia, ischemia, and inflammation across multiple organ systems. Upon activation by extracellular adenosine—whose availability is regulated by ENT transporters and CD73—ADORA2B signals through cAMP/PKA and MAPK/CREB pathways to stabilize the circadian protein PER2 (which supports HIF-1α-dependent glycolytic metabolism in cardiomyocytes and hippocampal neurons), suppress neutrophil and macrophage TNF-α and IL-6 release, enhance regulatory T cell differentiation, activate SERCA2α-dependent calcium homeostasis, and regulate red blood cell glycolytic flux and antioxidant defenses (PMID:22504483, PMID:22531331, PMID:22389701, PMID:26136425, PMID:41751389, PMID:40905089). ADORA2B expression is transcriptionally induced by HIF-1α during hypoxia and its protein stability is maintained through physical interaction with APIP, which prevents lysosomal degradation; the D296G variant that disrupts APIP binding abolishes cardioprotective activity (PMID:28701304, PMID:31263105). Cell-type-specific functions are prominent: myeloid ADORA2B constrains neutrophil-dependent inflammation in cardiac and renal ischemia-reperfusion injury but drives alternatively activated macrophage-dependent pulmonary fibrosis and hypertension through IL-6 and hyaluronan production, while on pulmonary artery smooth muscle cells it induces vascular remodeling mediators including HAS2 and TGM2 (PMID:23028059, PMID:25318478, PMID:29910735, PMID:27320922).
