Epithelial cells are closely connected to each other and to the extracellular matrix by a set of adhesive contacts that provide tissues with unique barrier properties and play a prominent role in cell morphology, tissue physiology, and cell signaling. This review highlights advances made in understanding the contributions of galectin-3, a carbohydrate-binding protein with affinity toward β-galactosides, as a modulator of epithelial junction assembly and function. The interactions of galectin-3 within adhesive structures are discussed in relation to wound healing and tumor progression.
上皮细胞通过一组黏附连接彼此紧密相连,并与细胞外基质相连,这些黏附连接赋予组织独特的屏障特性,并在细胞形态、组织生理学和细胞信号传导中发挥重要作用。本综述重点介绍了在理解半乳糖凝集素-3(一种对β-半乳糖苷具有亲和力的碳水化合物结合蛋白)作为上皮连接组装和功能调节剂方面所取得的进展。讨论了半乳糖凝集素-3在黏附结构中的相互作用与伤口愈合和肿瘤进展的关系。
