This invention provides compositions for inhibiting the binding between two cells, one expressing P- or L-selectin on the surface and the other expressing the corresponding ligand. A covalently crosslinked lipid composition is prepared having saccharides and acidic group on separate lipids. The composition is then interposed between the cells so as to inhibit binding. Inhibition can be achieved at an effective oligosaccharide concentration as low as 10
6
fold below that of the free saccharide. Since selectins are involved in recruiting cells to sites of injury, these composition scan be used to palliate certain inflammatory and immunological conditions.
本发明提供了一种抑制表达P-或L-选择素的细胞与表达相应
配体的另一种细胞之间结合的组合物。制备了一种共价交联的脂质组合物,其中
糖类和酸性基团分别存在于不同的脂质中。然后将该组合物插入细胞之间以抑制结合。在有效
寡糖浓度下,抑制可以达到低于游离
寡糖的106倍。由于选择素参与将细胞招募到损伤部位,因此这些组合物可以用于缓解某些炎症和免疫疾病。
