Peptide-mediated inhibition of neutrophil transmigration by blocking CD47 interactions with signal regulatory protein alpha.
CD47, a cell surface transmembrane Ig superfamily member, is an extracellular ligand for signal regulatory protein (SIRPalpha). Interactions between CD47 and SIRPalpha regulate many important immune cell functions including neutrophil (PMN) transmigration. Here we report identification of a novel function-blocking peptide, CERVIGTGWVRC, that structurally mimics an epitope on CD47 and binds to S...
متن کاملCd47-Signal Regulatory Protein α (Sirpα) Regulates Fcγ and Complement Receptor–Mediated Phagocytosis
In autoimmune hemolytic anemia (AIHA), circulating red blood cells (RBCs) opsonized with autoantibody are recognized by macrophage Fcgamma and complement receptors. This triggers phagocytosis and elimination of RBCs from the circulation by splenic macrophages. We recently found that CD47 on unopsonized RBCs binds macrophage signal regulatory protein alpha (SIRPalpha), generating a negative sign...

" marker of self " , also referred to as integrin-associated protein (IAP) due to association with integrins such as α V β 3, has been first described by Brown et al. in 1990. As member of the immunoglobulin superfamily it contains one IgV-like domain and five transmembrane regions. While it is expressed on virtually all cell types, levels of expression are dependent on the immune status of cel...
