Cell adhesion molecules are cell-surface proteins that account for cell-to-cell and/or cell-to-extracellular matrix (ECM) interactions. Cell adhesion molecules act at the cell surface where they interact with the molecules that are expressed on an opposing cell surface or are present in the ECM...
解析 细胞粘附分子(cell adhesion molecules,CAM):是指介导细胞间或细胞与细胞外基质间相互接触和结合的一类分子的统称,大多属于糖蛋白,以受体-配体结合的形式发挥作用,在胚胎的发育和分化、正常组织的维持、炎症与免疫应答、伤口修复、凝血及肿瘤的进展与转移等过程中具有重要意义。
The meaning of CELL ADHESION MOLECULE is any of various molecules (such as cadherins, integrins, and selectins) on the surface of a cell that bring about adhesion by binding to molecules on the surface of other cells or on extracellular material —abbrev
Synaptically localized cell adhesion molecules (SAMs), are multifunctional molecules that coordinate different aspects of synaptic development and function through specialized signalling or protein–protein interaction motifs. Neurexin–neuroligin signalling has a role in the development of pre- and postsynaptic...

Cell Adhesion Molecules Several types of molecule are specifically expressed on the cell surface to provide cell–cell recognition and cell adhesion to surrounding cells. Under quiescent conditions, adhesion molecules participate in maintenance of endothelial barrier function, enforcing contacts between ce...

E-cadherin is a major homophilic cell-cell adhesion molecule that inhibits motility of individual cells on matrix. However, its contribution to migration of cells through cell-rich tissues is less clear. We developed an in vivo sensor of mechanical tension across E-cadherin molecules, which we co...
