The application of HER2 and CD47 CAR-macrophage in ovarian cancer
Background The chimeric antigen receptor (CAR)-T therapy has a limited therapeutic effect on solid tumors owing to the limited CAR-T cell infiltration into solid tumors and the inactivation of CAR-T cells by the immunosuppressive tumor microenvironment ...

Professional antigen presenting cells (APCs) are deterred from phagocytosing cancer cells that express CD47. Here, the authors show that in glioblastoma mouse models, temozolomide improves the phagocytosis effect of CD47 blockade in APCs and results in ...

Upregulation of CD47 Is a Host Checkpoint Response to Pathogen Recognition
It is well understood that the adaptive immune response to infectious agents includes a modulating suppressive component as well as an activating component. We now show that the very early innate response also has an immunosuppressive component. Infected

219 CD47 and phosphatidylserine contribute to the interaction between antigen presenting cells and the allogeneic cell-based relapse vaccine DCP-001 [PDF]
Background DCP-001 is a cancer relapse vaccine derived from the DCOne® human leukemic cell line. During manufacturing, DCOne® cells are shifted towards a mature dendritic cell (mDC) phenotype, combining an endogenous tumor antigen repertoire (e.g.

Preclinical efficacy and toxicity studies of a highly specific chimeric anti‐CD47 antibody
Cluster of differentiation 47 (CD47) is a widely expressed self‐protection transmembrane protein that functions as a critical negative regulator to induce macrophage‐mediated phagocytosis.

PfMSA180 is a novel Plasmodium falciparum vaccine antigen that interacts with human erythrocyte integrin associated protein (CD47) [PDF]
AbstractMalaria symptoms and pathology are initiated by invasion of host erythrocytes by Plasmodium merozoites in a complex process that involves interactions between parasite and host erythrocyte proteins. Erythrocyte invasion presents attractive targets for malaria vaccine and drug development.

The landscape overview of CD47-based immunotherapy for hematological malignancies
Extensive clinical and experimental evidence suggests that macrophages play a crucial role in cancer immunotherapy. Cluster of differentiation (CD) 47, which is found on both healthy and malignant cells, regulates macrophage-mediated phagocytosis by ...

Novel CD47: SIRPα Dependent Mechanism for the Activation of STAT3 in Antigen-Presenting Cell
Cell surface CD47 interacts with its receptor, signal-regulatory-protein α (SIRPα) that is expressed predominantly on macrophages, to inhibit phagocytosis of normal, healthy cells. This "don't eat me" signal is mediated through tyrosine phosphorylation of SIRPα at the cytoplasmic ITIM motifs and the recruitment of the phosphatase, SHP-1.
