The suppressive effect of macrophages was enhanced by blocking CD47 on pancreatic cancer cells, leading to decreased metastatic burden and prolonged survival. This work supports a clinical trial of CD47 blockade as an adjuvant immunotherapy for pancreatic cancer.

Multiple myeloma (MM) remains to be incurable despite recent therapeutic advances. 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. In this study, we hypothesized that blocking the “don’t eat me&rdquo

Cancer Res. 24, 1415–1425 (2018). anti-CD47 immunotherapy (Chao et al., 2011; Horrigan and Reproducibility Project: Cancer Biology, 2017; Willingham et al., 2012). Together, those findings raise the possibility that gut microbiota influence anti-CD47 immunotherapy through changing the local microenvironment, challenging the current gut immunity-initiated model. Our study iden- However, the antitumor efficacy of CD47-based immunotherapy relies on the near-complete blockade of CD47 in the tumor microenvironment (TME; Ingram et al., 2017).

Immunotherapy is treatment that uses your body's own immune system to help fight cancer.

Recent clinical success of cancer immunotherapy has intensified interest in how tumors normally evade the immune response. Whether and how oncogenes contribute to this process are not well understood. In a study of mice, Casey et al.

An immunotherapy conceived at Stanford appeared safe in an early clinical trial. Half of the participants responded positively to the treatment, aimed at triggering macrophages to engulf cancer cells, the researchers reported.

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. It is an application of the fundamental research of cancer immunology and a growing subspeciality of oncology . Anti-CD47/PD-L1 immunotherapies aiming to enhance antitumor immunity are being intensively investigated and show promising results in cancer therapy; however, not all patients treated with these new drugs respond. Thus, developing new immunotherapy agents or combination treatments to enhance the efficacy of immunotherapy is an urgent challenge. However, immunotherapies related to innate responses such as CD47 blockade rely on the rapid immune responses within the tumor microenvironment.

CD47 binder till sitt 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.
