Adenosine Receptor Subtype A2a (A2aR) is a G-protein coupled receptor that mediates adenosine (a potent immunosuppressor) signaling in leukocytes. A2aR has been implicated in neuroinflammation and synaptic plasticity-related processes. Signaling through A2aRs inhibits local and systemic inflammation and A2aR expression showed protective effects against non-alcoholic steatohepatitis (NASH) in the liver. A2aR deficiency triggers spontaneous inflammation and NASH-Hepatocellular Carcinoma (HCC) in mice while low A2aR gene expression in human HCC is associated with hepatic inflammation and poor survival. Reducing adenosine signaling via A2aR antagonism provides an alternative targeted strategy to modulate the number and efficacy of infiltrating effector T cells within the immunosuppressive tumor microenvironment. Co-blockade of A2aR signaling and CD73 reduced tumor initiation, growth, and metastasis.
