Galectins are a family of carbohydrate-binding proteins that have a high affinity to galactosides on cell surfaces and extra cellular glycoproteins. They are involved in a variety of biological functions, including modulation of cell apoptosis, cell activation and inflammation. Our laboratory has recently identified galectin-3 binding protein (Gal-3BP) as being up-regulated in a microparticle proteomics analysis for deep venous thrombosis (DVT) patients compared to negative controls. P-selectin, another glycoprotein involved in thrombus propagation, has proven a promising target for DVT management and has been widely studied by our group. Galectins are involved in P-selectin expression and can potentially be implicated in the venous thrombogenesis process. The function of galectins, their role in inflammation and thrombosis as well as their potential implications as a new pharmacological target for DVT management are reviewed in this manuscript.
半乳糖凝集素是一类具有高亲和力与细胞表面半乳糖苷和细胞外糖蛋白结合的糖结合蛋白。它们参与多种生物学功能,包括调节细胞凋亡、细胞激活和炎症。我们实验室最近在深静脉血栓形成(DVT)患者与阴性对照的微粒蛋白组学分析中发现半乳糖凝集素-3 结合蛋白(Gal-3BP)上调。参与血栓传播的另一种糖蛋白 P-选择素已被证明是 DVT 管理的有前途的靶点,并且已被我们小组广泛研究。半乳糖凝集素参与 P-选择素的表达,并且可能参与静脉血栓形成过程。本文综述了半乳糖凝集素的功能、它们在炎症和血栓形成中的作用以及它们作为 DVT 管理新的药理学靶点的潜在意义。
