Extracellular Vesicles‐Derived Hybrid Nanoplatforms for Amplified CD47 Blockade‐Based Cancer Immunotherapy

Advanced Materials, 2023
Immunomodulation of tumor‐associated macrophages (TAMs) into tumor‐inhibiting M1‐like phenotype is a promising but challenging strategy. Cleverly, tumor cells overexpress CD47, a “don't eat me” signal that ligates with the signal regulatory protein alpha

CD47 [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2008
CD47, originally named integrin-associated protein, is a receptor for thrombospondin-1. A number of important roles for CD47 have been defined in regulating the migration, proliferation, and survival of vascular cells, and in regulation of innate and adaptive immunity.

Reprogramming of TAMs via the STAT3/CD47-SIRPα axis promotes acquired resistance to EGFR-TKIs in lung cancer.

Cancer Letters, 2023
Cross-talk between the tumor microenvironment (TME) and cancer cells plays an important role in acquired drug resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs).

CD47 Peptide-Cloaked Lipid Nanoparticles Promote Cell-Specific mRNA Delivery.

Molecular Therapy
mRNA-based therapeutics delivered via lipid nanoparticles (LNP-mRNA) hold great promise for treating diverse diseases. However, further improvements are needed to refine outcomes in non-vaccine, extrahepatic applications, such as minimizing the ...

Is CD47 a potentially promising therapeutic target in cardiovascular diseases? — Role of CD47 in cardiovascular diseases

Life Sciences, 2020
CD47 (cluster of differentiation 47) is a ubiquitously expressed transmembrane protein that belongs to the immunoglobulin superfamily. CD47 is both a receptor for the matricellular protein thrombospondin-1 (TSP-1) and a ligand for signal-regulatory protein alpha (SIRPα).

USP2 inhibition unleashes CD47-restrained phagocytosis and enhances anti-tumor immunity

Nature Communications
The CD47/SIRPα axis conveys a ‘don’t eat me’ signal, thereby thwarting the phagocytic clearance of tumor cells. Although blocking antibodies targeting CD47 have demonstrated promising anti-tumor effects in preclinical models, clinical trials involving ...

Nanoparticle-Mediated CD47-SIRPα Blockade and Calreticulin Exposure for Improved Cancer Chemo-Immunotherapy.

ACS Nano, 2023
Enabling macrophages to phagocytose tumor cells holds great potential for cancer therapy but suffers from tremendous challenges because the tumor cells upregulate antiphagocytosis molecules (such as CD47) on their surface.
