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

IDO inhibition in cancer immunology

IDO ( indoleamine 2,3-dioxygenase) is a molecule that oxidizes tryptophan, which is needed by cytotoxic T-cells. When cancer cells and T-reg cells secrete IDO in the vicinity of cytotoxic T cells, antitumor activity is abrogated.   Continue reading
