HHV-8 expresses a viral antigen called LANA-1 which prevents apoptosis and facilitates uncontrolled cellular proliferation.

HHV-8会表达一种叫做LANA-1的抗原；该抗原会阻碍细胞凋亡并导致细胞增殖失控。

In the latent phase, the virus just hangs out in the cell without destroying it, and expresses the viral latency-associated nuclear antigen, or LANA-1.

在潜伏期，病毒仅停留在细胞内不会破坏细胞，并会表达病毒潜伏相关核抗原（LANA-1）。

Although it's not always needed, diagnostic testing for RSV can be done by swabbing epithelial cells in the nasopharynx and looking for the presence of viral antigens.

可以通过擦拭鼻咽部上皮细胞，检查是否存在病毒抗原，但这一检查并不是人人都必要的。
