We have examined the agglutination of Sindbis virus and of chick and hamster cells infected with Sindbis virus by two of the plant lectins, concanavalin A and Ricinus communis agglutinin. Both lectins agglutinate the virus by binding to the polysaccharide chains of the envelope glycoproteins. Both chick and hamster cells exhibit increased agglutination by the lectins after infection by Sindbis virus. In the case of chick cells infected with Sindbis virus, this increase in agglutinability occurs between 3 and 5 h after infection. Infected and mock-infected cells bind the same amount of (3)H-labeled concanavalin A, which suggests that the increase in agglutination after infection is due to rearrangements at the cell surface rather than to insertion of new lectin binding sites per se.
我们研究了伴刀豆球蛋白A和蓖麻凝集素这两种植物凝集素对辛德毕斯病毒以及感染了辛德毕斯病毒的鸡和仓鼠细胞的凝集作用。两种凝集素均通过与包膜糖蛋白的多糖链结合来凝集病毒。鸡和仓鼠细胞在感染辛德毕斯病毒后,对凝集素的凝集作用均增强。对于感染了辛德毕斯病毒的鸡细胞,这种凝集性的增强发生在感染后3至5小时之间。感染组和 mock感染组细胞结合的(3)H标记伴刀豆球蛋白A量相同,这表明感染后凝集作用的增强是由于细胞表面的重排,而非新凝集素结合位点本身的插入。
