CD47 receptor as a primary target for cancer therapy

Abstract

Recently, a number of new highly efficient antibody-based anticancer therapeutics have emerged. These receptor-binding antibodies have beneficial toxicity profiles associated with relatively mild side effects. Therefore, the search for novel surface proteins that are present on cancer cells and play important metabolic or defensive roles has intensified. Additionally, the therapeutic stimulation of patient’s immune system in order to aim its components, specifically, phagocytes and cytotoxic T-lymphocytes, at tumor cells is gaining traction. This review is focused on the CD47 surface receptor, a ubiquitously expressed molecule, which could nevertheless serve as a therapeutic target due to its ability to simultaneously stimulate both natural and adaptive immune response.
