Abstract

Inducibility of Ia molecules on cultivated astrocytes by JHM virus correlates with demyelinating disease susceptibility of animals from which these astrocytes are derived. On the contrary, class I induction of both astrocytes and oligodendrocytes occurs as a consequence of normal cultivation procedures in both susceptible and resistant strains. Increased expression of class I antigens on rat astrocytes and oligodendrocytes is not related to JHM viral infection as it is in the mouse. These data indicate that strain differences in Ia inducibility, rather than inducibility of class I antigens, by JHM virus may explain higher levels of T cell-mediated damage to myelin during infection in susceptible rat strains compared with resistant strains.

摘要

JHM病毒对培养的星形胶质细胞Ia分子的诱导能力与这些星形胶质细胞来源动物的脱髓鞘疾病易感性相关。相反,在易感和抗性品系中,星形胶质细胞和少突胶质细胞的I类诱导是正常培养程序的结果。大鼠星形胶质细胞和少突胶质细胞上I类抗原表达的增加与JHM病毒感染无关,而在小鼠中则相关。这些数据表明,JHM病毒诱导Ia的能力差异而非诱导I类抗原的能力差异,可能解释了与抗性品系相比,易感大鼠品系在感染期间T细胞介导的髓鞘损伤水平更高的原因。
