The SIRPα–CD47 axis was found to be highly species specific. Together, the results demonstrate that disruption of the SIRPα–CD47 immune checkpoint may augment NK cell antitumor responses and that elevated expression of CD47 may prevent NK cell–mediated killing of allogeneic and xenogeneic tissues.

Purified anti-mouse CD47 Antibody - CD47, also known as Integrin-Associated Protein (IAP), is a membrane protein of about 50 kD with an IgV-like extracelluluar domain, a five membrane-spanning segment and a short terminal cytoplasmic region.

Purified anti-mouse CD47 Antibody - CD47, also known as Integrin-Associated Protein (IAP), is a membrane protein of about 50 kD with an IgV-like extracelluluar domain, a five membrane-spanning segment and a short terminal cytoplasmic region. 2021-03-09 · CD47 is a 50-kDa transmembrane surface protein with an extracellular IgV domain that is ubiquitously expressed at varying levels across all cell types (2, 3). CD47 is a potent “don’t eat me” signal regulating programed cell removal (PrCR) (4, 5).

This antibody reacts with Ig domain of CD47 protein. CD47, originally named integrin-associated protein (IAP), is a 50 kDa protein containing five

It tells circulating immune cells called macrophages not to eat these cells. The body uses the CD47 protein to protect cells that should be protected and to help dispose of cells that are aged or diseased.

CD47 (also called integrin-associated protein) is the “receptor” for TSP1 and the “ligand” for SHP-1-recruiting inhibitory immunoreceptor signal regulatory protein (SIRPα), also known as MFR and CD172a. Both CD47 and SIRPα belong to the immunoglobulin superfamily and both conduct signaling inwards.

However, targeting CD47 led to significant anemia and thrombocytopenia in both pre-clinical studies and phase I trials as CD47 is also expressed on normal red blood cells (RBCs) and platelets. Responsiveness of cells to CD47 ligation increased following DRP1 overexpression, while resistance to CD47-mediated death was observed following DRP1 downregulation.

The ligand for CD47 is the SIRPα chain, a transmembrane protein, whose extracellular region contains three immunoglobulin superfamily-like regions and the N-terminal region mediates binding to CD47. CD47-Directed TTI-622 Elicits Early Efficacy Signals in Relapsed/Refractory Lymphoma Tissue distribution and regulation of CD47 and binding partners . Expression of CD47 in normal cells and cancer. CD47 is expressed on almost all normal human cells, as evaluated by mRNA expression and immunohistochemical staining, and occurs in four highly conserved isoforms that differ only in the length of their cytoplasmic domain, ranging from 3 to 36 amino acids (Reinhold et al., 1995).

Both CD47 and SIRPα belong to the immunoglobulin superfamily and both conduct signaling inwards. “There may be circumstances where host responses need boosting and CD47 represents a novel target for host-directed therapies in such cases,” the scientists write, mentioning SARS-CoV-2, HIV, HPV and Ebola virus among several possibilities.

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.
