Adenosine – a critical checkpoint in the tumor microenvironment

The tumor microenvironment (TME) includes a host of cells (mesenchymal, immune, vascular), cytokines, and other signaling molecules that serve to abrogate the innate and adaptive immune responses against the tumor. This is appropriate to maintain tissue homeostasis, and to prevent autoimmunity after the rogue cancer cells have been eliminated. Cancer cells co-opt many of these pathways to terminate the effective immune response so that they are not wiped out, rather, proliferate, invade, metastasize and kill, Continue reading
