食用菌凝集素的研究进展

凝集素是一类不同于免疫球蛋白的蛋白质或糖蛋白，能与糖专一地、非共价地可逆结合，并具有凝集细胞和沉淀聚糖或糖复合物的作用：它具有鉴定血型，鉴定微生物，促进细胞分裂，抗感染、抗炎症、抗血栓、抗肿瘤，免疫调节等功效．已成为生物化学、细胞生物学、免疫学、医学以及相关领域的特效工具：近几年来，国内外对食用菌凝集素的研究不断升温，本文从其制备方法、来源、结构、物化性质、功能性等方面作一简单综述。

Advances in the study on lectin from edible fungi

A lectin is a sugar-binding protein or glycoprotein of non-immune origin that agglutinates ceus or precipitates glycoconjugates.It has such functions as determining blood types and micro-organisms species, immunomodulatory activity, mitogenic activity etc,thus making it a useful research tool in the area of immunology, biological chemistry,medicine. In recent years,a lot of attention is paid on lectin from edible fungi,including its preparation, physical and chemical characteristics, functions and so on. Such research status is reviewed in this article.
