Rat parvovirus (RPV) is nonpathogenic in rats but causes persistent lymphocytotropic infection. We found that RPV was propagated in rat thymic lymphoma cell line C58(NT)D and induced apoptosis. Interestingly, a resistant subclone, C58(NT)D/R, from surviving cells after lytic infection had differentiated phenotypic modifications, such as increased cell adherence, resistance to apoptosis, and suppressed tumorigenicity.
大鼠细小病毒(RPV)对大鼠无致病性,但会引起持续性嗜淋巴细胞感染。我们发现RPV可在大鼠胸腺淋巴瘤细胞系C58(NT)D中增殖并诱导细胞凋亡。有趣的是,来自溶细胞感染后存活细胞的抗性亚克隆C58(NT)D/R具有分化的表型修饰,如细胞黏附增加、抗凋亡能力增强以及致瘤性受到抑制。
