Abstract

Fractions of nerve cell perikarya, synaptosomes, and astrocytic glia were prepared from human, monkey , rabbit, rat, and mouse brain tissue. The herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) binding capacity of these fractions was studied. Pretreatment of fractions with one type of HSV and the subsequent testing of adsorption of homotypic and heterotypic virus ws employed to reveal type selectivity of virus binding receptors. A higher density of HSV-1 than of HSV-2 selective receptors was found on synaptosomes and glial cells, except with mouse-derived preparations. Synaptosomal and glial cell preparations of mouse brains adsorbed both types of HSV well. Little or no adsorption was observed with HSV-1 and HSV-2 to neuronal perikarya. The type selectivity of HSV binding receptors on brain cells ws demonstrated on preparations of human synaptosomes and mouse glial cells. Some possible implications of the observations on the HSV infection of the nervous system are discussed.

摘要

从人、猴、兔、大鼠和小鼠的脑组织中制备神经细胞胞体、突触体和星形胶质细胞部分。研究了这些部分对单纯疱疹病毒1型(HSV-1)和2型(HSV-2)的结合能力。用一种类型的HSV对这些部分进行预处理,随后测试同型和异型病毒的吸附情况,以揭示病毒结合受体的类型选择性。在突触体和神经胶质细胞上发现HSV-1选择性受体的密度高于HSV-2,小鼠来源的制剂除外。小鼠脑的突触体和神经胶质细胞制剂对两种类型的HSV都有良好的吸附。HSV-1和HSV-2对神经元胞体几乎没有或没有吸附。在人突触体和小鼠神经胶质细胞制剂上证明了脑细胞上HSV结合受体的类型选择性。讨论了这些观察结果对神经系统HSV感染的一些可能影响。
