Abstract 5909: Inhibition of Cd39 and Cd73 by 3rd-generation antisense oligonucleotides to improve immunity against tumors

During the last decades it became obvious that the immune system can be utilized to evoke effective antitumor responses. However, cancer cells develop mechanisms to circumvent this. The two ectonucleotidases CD39 and CD73 are promising drug targets, as they act in concert to convert extracellular immune-stimulating ATP to immunosuppressive adenosine. CD39 and CD73 are expressed on different immune cells as well as on a range of cancer cells and...
