The present invention concerns fusion of half-life extending vehicles, preferably Fc domains, with peptide sequences that act as antagonists of integrins, selectins, cell adhesion molecules, or their respective receptors. Linkage to the vehicle increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The peptide may be an existing peptide or a peptide selected by phage display,
E. coli
display, ribosome display, RNA-peptide screening, chemical-peptide screening, or other methods.
本发明涉及将半衰期延长载体(优选为Fc区域)与作为整合素、选择素、细胞黏附分子或其相应受体的拮抗剂的肽序列融合。与载体的连接增加了肽的半衰期,否则该肽在体内会很快降解。该肽可以是现有的肽或通过噬菌体展示、大肠杆菌展示、核糖体展示、RNA-肽筛选、化学-肽筛选或其他方法选择的肽。
