CD47 is an antiphagocytic ligand broadly expressed on normal and malignant tissues that delivers an inhibitory signal through the receptor signal regulatory protein alpha (SIRPα). Inhibitors of the CD47–SIRPα interaction improve antitumor antibody responses by enhancing antibody-dependent cellular phagocytosis (ADCP) in xenograft models.

Introduction: CD47 is an anti-phagocytic ('don't eat me') signal overexpressed in many malignant diseases. It acts as myeloid immune checkpoint and thus has prognostic and therapeutic implications. Areas covered : This review presents and discusses the currently available data on the prognostic role and therapeutic value of CD47 in gastrointestinal tumors.

Image captured at the NIAID Integrated Research Facility (IRF) in Fort Detrick, Maryland. Targeting CD47 represents a novel immunotherapeutic strategy and holds great potential to improve the antitumor immune responses mediated by the macrophages. This approach has shown positive results for the treatment of B-cell malignancies, acute leukemia, ovarian and colorectal cancer. CD47 is a ubiquitously expressed immunoregulatory protein best known for its so-called 'don't eat me' function that prevents phagocytic removal of healthy cells by the immune system. Many types of cancer present high levels of this don't eat me signal on their surface, thereby disrupting anti-cancer immune responses.

It's not chemotherapy, radiation or surgery.

2019-01-15 · Blocking the CD47–SIRPα interaction with CD47 monoclonal antibody (mAb) induces phagocytosis of both tumor and ferumoxytol nanoparticles. Increased uptake of ferumoxytol nanoparticles generates T2 contrast on MR scans that can serve as an imaging biomarker for monitoring responses to CD47 immunotherapy NIH investigators and colleagues have discovered that when the immune system first responds to infectious agents such as viruses or bacteria, a natural brake on the response prevents overactivation. Their new study in mBio describes this brake and the way pathogens such as SARS-CoV-2, the virus that causes COVID-19, turn it on. Their finding provides a potential target for an immunotherapy CD47 is a critical self-protective “don’t eat me” signal on multiple human cancers against macrophage immunosurveillance.

Further, blocking of CD47 using an anti-CD47 antibody induced immediate activation of macrophages, which resulted in induction of phagocytosis and killing of MM cells in the 3D-tissue engineered bone marrow model, as early as 4 hours. These results suggest that macrophage checkpoint immunotherapy by blocking the CD47 “don’t eat me”

CD47, an immune checkpoint known as the “don’t eat me” signal, is highly expressed on the surface of various cancers, allowing cancer cells to send inhibitory signals to macrophages and impede phagocytosis and immune response.

The CD47 gene is located on chromosome 3q13 and encodes an integrin-associated protein. CD47 is an important “self-labeling” molecule in the immunoglobulin superfamily that contains an immunoglobulin variable-like amino-terminal domain, five transmembrane domains, and one carboxy-terminal intracellular tail (34, 35). CD47 is found to be overexpressed on tumor cells and act as a don’t eat me’ signal, which contributes to immune evasion. Macrophages mediated phagocytosis via blockade CD47/SIRPα (signal regulatory protein alpha) interaction was proved to induce effective antitumor immune response. Cancer immunotherapy (sometimes called immuno-oncology) is the artificial stimulation of the immune system to treat cancer, improving on the immune system's natural ability to fight the disease.
