, who had demonstrated in red blood cell (RBC) transfusion experiments that WT mice rapidly eliminate syngeneic Cd47-null (Cd47 −) RBCs through erythrophagocytosis in the spleen and that the lack of tyrosine phosphorylation in SIRPα ITIMs was associated with this macrophage aggressiveness. Blocking the CD47-SIRPa axis by delivery of anti-CD47 antibody induces antitumor effects in glioma and glioma stem cells Feng Li #, Bingke Lv , Yang Liu, Tian Hua, Jianbang Han, Chengmei Sun, Limin Xu, Zhongfei Zhang, Zhiming Feng, Yingqian Cai, Yuxi Zou, Yiquan Ke, and Xiaodan Jiang Purpose: CD47 plays a variety of roles in intercellular signaling. 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. Experimental Design: Quantitative real-time PCR was used to CD47 overexpression is a common feature of hematologic and solid tumors (7–10).

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 development in cancer across 28 different targets. Has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity). Receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. 2019-03-04 CD47 ligation altered SIRPA localization, positioning SIRPA for activation at the phagocytic synapse. At the phagocytic synapse, SIRPA inhibited integrin activation to limit macrophage spreading across the surface of the engulfment target.

We demonstrate the effect of a humanized anti-CD47 antibody, Hu5F9-G4, on five aggressive and etiologically distinct pediatric brain tumors: group 3 medu lloblastoma (primary and metastatic), atypical teratoid Inhibitory immune checkpoint blockade has been one of the most significant advances in anticancer therapy of the past decade. 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 phagocytosis checkpoint in macrophages and other innate immune cells, may be an interesting Virtual Passes entitle you to: A personalized experience, which plugs directly into your calendar.; Hours of networking opportunities, 1-2-1 meetings, structured formats, Speed Networking sessions, and more.; The opportunity to jump in and out of meetings, networking, and content as you wish.; Take part in 9+ hours of interactive content featuring 25+ expert speakers from across the industry.

[6] 2020-05-19 · The CD47-signal regulatory protein alpha (SIRPa) interaction is a therapeutic target for human solid tumors. Proc Natl Acad Sci U S A .

The CD47/signal regulatory protein alpha (SIRPα) axis is a critical regulator of myeloid cell activation and serves a broader role as a myeloid-specific immune checkpoint. CD47 is highly expressed on many different types of cancer, and it transduces inhibitory signals through SIRPα on macrophages and other myeloid cells. 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. Blocking the CD47-SIRPa axis by delivery of anti-CD47 antibody induces antitumor effects in glioma and glioma stem cells Feng Li #, Bingke Lv , Yang Liu, Tian Hua, Jianbang Han, Chengmei Sun, Limin Xu, Zhongfei Zhang, Zhiming Feng, Yingqian Cai, Yuxi Zou, Yiquan Ke, and Xiaodan Jiang CD47 overexpression is a common feature of hematologic and solid tumors (7–10). By binding and activating signal regulatory protein– a (SIRPa), an inhibitory protein expressed on the surface of myeloid cells, CD47 serves as an anti-phagocytic or “don’teatme” signal (11–15). Actively or passively take part in this session.

(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.
