细胞与细胞，细胞与细胞外基质粘附作用，是机体构建或维持组织或器官以及功能最基本的生命现象。细胞粘附分子是一群在多种细胞上表达，介导细胞间粘附和作用的糖蛋白物质。它们除参与介导细胞粘附机制，还互相传递信息，调节细胞功能，并与许多疾病密切相关。对其粘附机制的阻断，使之成为临床上治疗的一个有效手段，已引起人们的关注。 Cells and cells, cells and extracellular matrix adhesion, is the body to build or maintain the organization or organ and function of the most basic life phenomena. Cell adhesion molecules are a group of glycoproteins that are expressed on a variety of cells and mediate cell-cell adhesion and function. In addition to their involvement in mediating cell adhesion mechanisms, they also transmit information to each other, modulate cellular function and are closely linked to many diseases. The blocking mechanism of its adhesion, making it an effective means of clinical treatment, has aroused people’s attention.
