Interleukin (IL)-22, a member of the IL-10 family, plays a role in antiviral immune responses to a number of viral infections. However, it is unclear whether IL-22 is involved in the mucosal immunity against herpes simplex virus 2 (HSV-2) infection in the female reproductive tract (FRT). In this study, we studied whether IL-22 could inhibit HSV-2 infection of human cervical epithelial cells (End1/E6E7 cells). We showed that End1/E6E7 cells express the functional IL-22 receptor complex (IL-22R1 and IL-10R2). When treated with IL-22, End1/E6E7 cells expressed the higher levels of IFN-stimulated genes (ISGs: ISG15, ISG56, OAS-1, OAS-2, and Mx2) than untreated cells. In addition, IL-22-treated cells produced higher levels of the tight junction proteins (ZO-1 and Occludin) than untreated cells. Mechanistically, IL-22 could activate the JAK/STAT signaling pathway by inducing the phosphorylation of STAT1 and STAT3. These observations indicate the potential of IL-22 as an anti-HSV-2 agent in the FRT mucosal innate immunity against HSV-2 infection.
白细胞介素 (IL)-22 是 IL-10 家族的一员，在多种病毒感染的抗病毒免疫反应中发挥作用。然而，目前尚不清楚 IL-22 是否参与女性生殖道 (FRT) 对单纯疱疹病毒 2 (HSV-2) 感染的黏膜免疫。在这项研究中，我们研究了 IL-22 是否可以抑制 HSV-2 感染人宫颈上皮细胞 (End1/E6E7 细胞)。结果表明，End1/E6E7 细胞表达功能性的 IL-22 受体复合物 (IL-22R1 和 IL-10R2)。用 IL-22 处理后，与未经处理的细胞相比，End1/E6E7 细胞表达更高水平的干扰素刺激基因 (ISGs：ISG15、ISG56、OAS-1、OAS-2 和 Mx2)。此外，与未经处理的细胞相比，IL-22 处理的细胞产生更高水平的紧密连接蛋白 (ZO-1 和 Occludin)。从机制上讲，IL-22 通过诱导 STAT1 和 STAT3 的磷酸化来激活 JAK/STAT 信号通路。这些观察结果表明，IL-22 有可能成为 FRT 黏膜固有免疫中针对 HSV-2 感染的抗 HSV-2 药物。
