嗜淋巴细胞疱疹病毒KSHV主要在体内感染B细胞,并与几种人B细胞淋巴增生综合征有关。在这里,我们研究的易感性的主要扁桃体淋巴细胞感染的重组KSHV(rKSHV.219),组成型表达GFP。在MOI约为1时,约5-10%的CD 19 + B细胞变为GFP阳性。令人惊讶的是,在相同的培养物中,更多的T细胞被感染。然而,与分离的B细胞相反,分离的感染的T细胞不支持正确的病毒转录,并且不产生感染性病毒,这表明存在一个或多个进入后阻断裂解性KSHV在T细胞中的复制。在B或T细胞中尚未观察到永生化或转化。这些结果肯定了研究KSHV感染的初级淋巴细胞的可行性,并有助于合理化检测KSHV DNA在罕见的人类T细胞淋巴瘤体内。
The lymphotropic herpesvirus KSHV principally infects B cells in vivo and is linked to several human B cell lymphoproliferative syndromes. Here we examine the susceptibility of primary tonsillar lymphocytes to infection by a recombinant KSHV (rKSHV.219) that constitutively expresses GFP. At an MOI of ~ 1, ca 5–10% of CD19+ B cells became GFP-positive. Surprisingly, in the same culture many more T cells became infected. However, in contrast to isolated B cells, isolated infected T cells did not support correct viral transcription and did not produce infectious virus, indicating the presence of one or more post-entry blocks to lytic KSHV replication in T cells. No immortalization or transformation has yet been observed in either B or T cells. These results affirm the feasibility of studying KSHV infection in primary lymphoid cells, and help to rationalize the detection of KSHV DNA in rare human T cell lymphomas in vivo.
