CD47 and SIRPA were expressed by Treg cells and VM neurons, respectively. CD47-labeled Treg cells dynamically contacted with SIRPA-labeled VM neurons. Silencing CD47 gene in Treg cells impaired the ability of Treg cells to protect dopaminergic neurons against MPP+ toxicity.

At the phagocytic synapse, SIRPA inhibited integrin activation to limit macrophage spreading across the surface of the engulfment target. Research so far has largely focused on improving adaptive immune functions, but recent studies have indicated that the signal-regulatory protein (SIRP)α-CD47 pathway, a phago … Inhibitory immune checkpoint blockade has been one of the most significant advances in anticancer therapy of the past decade.

In the present study, 269 advanced CRC lesions were immunohistochemically evaluated for CD47, SIRPA, CD68, and CD163 expression in tumor cells and TAIs. This CD47/SIRP alpha binding assay can be run in a 96- or 384-well low volume white plate (20 µL final). As described here, samples or standards are dispensed directly into the assay plate, and the tagged CD47 & SIRP alpha protein are then added, followed by the dispensing of the HTRF reagents.

2020-3-14 · CD47是广泛表达于正常细胞表面的一种蛋白质，通过与巨噬细胞表面的SIRPα结合，释放一种“别吃我”信号，从而保护健康细胞不被巨噬细胞“吃掉”。不幸的是，癌细胞也学会了这一机制：在表面过表达CD47，使巨噬细胞将它们当作“正常细胞”，从而躲避了被“吃掉”的命运。

We have demonstrated that monoclonal antibodies that block CD47 are effective for treating human solid tumors in vitro and in vivo. We anticipate that these findings will extend to all modalities that interfere with the CD47-SIRPa interaction. Polymorphisms in the human inhibitory signal-regulatory protein alpha do not affect binding to its ligand CD47. SIRPA plays a protective role in cardiac hypertrophy through negative regulation of the Toll-like receptor 4/nuclear factor-kappaB pathway. The Targeting the CD47-SIRPA Axis in Oncology: Analytical Tool is continuously updated according to twelve of the world's most influential meetings in oncology (AACR, ASCO, ASGCT, ASH, CMIT, EHA SIRPα recognizes CD47, an anti-phagocytic signal that distinguishes live cells from dying cells. CD47 has a single Ig-like extracellular domain and five membrane spanning regions. The interaction between SIRPα and CD47 can be modified by endocytosis or cleavage of the receptor, or interaction with surfactant proteins.

Makrofa- gerna visar sig vara utrustade med en inhiberande receptor, SIRPa, vilken känner igen proteinet CD47, vilket till skillnad från MHC finns uttryckt på.

By interacting with various ligands, CD47 has roles in the regulation of cell motility, adhesion, migration, and platelet activation. Macrophages lacking SIRPA do not exhibit reduced phagocytosis of CD47-bearing targets, suggesting that SIRPA is the primary transducer of the CD47 signal (Okazawa et al., 2005; Oldenborg et al., 2000).

(B) SIRPa/CD47 blockade promotes phagocytosis of tumor cells driven by pro-phagocytic ligands and/or FcgR engagement by Fc-functional antibodies (ADCP). (C) SIRPa/CD47 inhibitors vary in molecular structure and mechanism-of-action but can be broadly categorized as Fc-silent vs. Fc-functional. CD47/SIRPα, AN IMMUNE CHECKPOINT FORINNATE IMMUNE SYSTEM. Among cells of the myeloid lineage, macrophage has prominent potentials as the mediator of anti-cancer therapeutics based on its robust phagocytosis ability [8, 9]. CD47, known as an integrin-associated protein, was first identified as a transmembrane protein from red blood cells (RBC) . Blocking CD47 on soft RBCs leads to the characteristic hourglass deformations seen when native RBCs from different species are engulfed, 71 consistent with CD47-SIRPA interactions being species specific.
