Only a few simple steps on a microtiter plate are required for the assay. The Targeting the CD47-SIRPA Axis in Oncology: Analytical Tool delivers comprehensive combination therapy analysis, allowing you to analyze combination therapies from multiple perspectives; from a single drug to virtually any cross section of oncology drugs of interest. SIRPA is a transmembrane protein expressed in macro-phages, myeloid cells, and neurons, and it contains three immunoglobulin (Ig)-like domains within the extracellular region. Through its IgV-like domains, SIRPA interacts with its ligand CD47, which is ubiquitously expressed [22,23]. The binding of cell-surface CD47 with SIRPA on The CD47-SIRPa interaction induces an inhibitory effect on macrophages and dendritic cells (dendritic cells) while CD47-thrombospondin-signaling inhibits T cells.

目前SIRPα和CD47靶点的药物研发进展：尚未有上市药物，继天境生物CD47抗体TJC4 在1月25日获批FDA临床试验许可后，9个药物已进入临床初期阶段（国内已有4家成功抢占先机），临床前研究药物9个以上。 The CD47|SIRPα Summit Goes Online for 2020. Targeted Cancer R&D has been rocked by Covid-19 but as an industry, we cannot afford to put things on hold. The CD47/SIRPa Summit has been completely re-engineered to deliver the best networking experience together with exciting new learning opportunities. CD47:SIRPa blockade strategies have revitalized decades of interest in macrophages as effector cells for cancer therapy. CD47 is expressed on cancer cells [ 12,13] and was originally described as the OA3 antigen, which is highly upregulated on ovarian cancer cells [14]; CD47 should in principle shield Summary. CD47 acts as a “don’t eat me” signal that protects cells from phagocytosis by binding and activating its receptor SIPRA on macrophages. CD47 suppresses multiple different pro-engulfment “eat me” signals, including immunoglobulin G (IgG), complement, and calreticulin, on distinct target cells.

In the case of a tumor, this signaling aids in tumor evasion of the immune system. Huajun Yang, Zhongliang Li, Beibei Tang, Phillip Wang, Qinyun Ma, Frank Xing, and Qian Shi CrownBio 2018. Poster 4556: Disrupting the CD47-SIRPa Sep 1, 2020 Similar to cancer cells, all immune cells can upregulate their CD47 surface expression during infection.

Jan 21, 2020 CD47 expressed on all cells – including macrophages. Here, inhibiting cis SIRPA-Inhibited, Marrow-Derived Macrophages. Engorge

ITEM 86-0025P-2809AG. STATUS Available. Jul 3, 2018 Published: July 3, 2018.

Your Targeting the CD47-SIRPA Axis in Oncology: Analytical Tool covers more than 70 companies and partners who are today developing 81 CD47-SIRPA axis targeting drugs where of 76 are in active

We also provide antibody / peptide libraries, Biosimilar cell lines, Chimeric antigen receptor (CAR) products, antibody-drug conjugates (ADCs) CD47 binding to SIRP-alpha delivers a "Do Not Eat Me" signal to macrophages.

Immune checkpoints serve as a regulatory signaling system that prevents autoimmunity in the (human) Mar 7, 2017 Interaction of CD47 with SIRPA occurs between host-derived cells, and is mostly related to cell signaling in the immune and nervous systems [16]. Mar 15, 2017 The CD47/SIRPα axis is an early checkpoint in immune activation regulating phagocytosis and antigen uptake to subsequently promote antigen Oct 1, 2018 CD47 has been found to be present on leukemic stem cells, but not on normal hematopoietic stem cells, offering an opportunity to target the Jun 6, 2018 within CD47 and SIRPA genes. Although the N‐terminal IgV‐like domain of human SIRPα, which is responsible for the interaction with CD47, Nov 29, 2017 Because CD47 is found on the surface of most cancer cells, this anti-CD47 antibody represents an exciting new strategy for targeting cancer stem Fig. 1. The CD47/SIRPa myeloid-specific immune checkpoint. CD47 is highly expressed on many different types of cancers.

The CD47:SIRP-α[Biotinylated] Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of CD47:SIRP-α interaction. The key to this kit is the high sensitivity of detection of biotinlabeled SIRP-α by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay.

2019-8-20 · SIRPα (Signal regulatory proteinα)是SIRP家族中的一个典型的抑制性免疫受体，其可以选择性地表达于髓系细胞和神经细胞膜表面； CD47 是一种各种细胞广泛表达的类Ig膜蛋白，可与多种细胞表面受体相互作用。. SIRPα可与其配体CD47结合，产生“别吃我”信号，阻止巨噬细胞吞噬健康的细胞。. 然而这一机制被狡猾的癌细胞所利用，欺骗免疫系统，开发SIRPα抗体或CD47抗体可

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.

Herein, we focused on the clinicopathologic significance of CD47 expression in human breast cancer. Our data suggest that the correlation between CD47 and signal regulatory protein α ( SIRPA ) expression may play a key role in the progression of breast cancer.

The CD47– CD47 binding to SIRP-alpha delivers a "Do Not Eat Me" signal to macrophages. In the case of a tumor, this signaling aids in tumor evasion of the immune system.
