Measles virus induced a marked increase in the expression of MHC-coded class I and class II antigens as detected by immunostaining during both fatal and non-fatal brain infections in rats. The distribution of these molecules in the brain was much more widespread than the occurrence of viral antigen suggesting a soluble factor for their induction. In 14-day-old rats with a non-fatal infection there was a marked infiltration of T lymphocytes of 'cytotoxic/suppressor' phenotype in the brain parenchyma, whereas T 'helper' cell phenotypes mainly were located perivascularly. In brains from newborn rats with a fatal infection no or only few lymphocytes were detected.
在大鼠致命性和非致命性脑感染期间,通过免疫染色检测发现,麻疹病毒可显著增加主要组织相容性复合体(MHC)编码的Ⅰ类和Ⅱ类抗原的表达。这些分子在脑中的分布比病毒抗原的出现更为广泛,提示存在一种可诱导它们产生的可溶性因子。在14日龄非致命性感染的大鼠中,脑实质内有大量“细胞毒性/抑制性”表型的T淋巴细胞浸润,而T“辅助性”细胞表型主要位于血管周围。在新生大鼠的致命性感染脑内未检测到淋巴细胞或仅检测到少量淋巴细胞。
