Tiivistelmä
Interleukin-27 (IL-27) inhibits the replication of many viruses, but the mechanism differs according to virus and cell type. In this study, we observed that IL-27 expression was upregulated in herpes simplex virus type 1 (HSV-1)-infected SJL/J mice, which led us to further investigate the role of IL-27 in HSV-1 infection using epithelial, glioma, and immunological cells as cell models. We showed that in all studied cell lines, the IL-27 messenger RNA (mRNA) level was upregulated due to the HSV-1 infection. When the cells were primed with IL-27 before the virus infection, the virus release was prevented, indicating an antiviral role of IL-27 in HSV-1 infection. Furthermore, we observed that IL-27 secretion to the culture medium was reduced in infected epithelial and immunological cells, but not in glioma cells. Not surprisingly, HSV-1 induced type I, II, and III interferons regardless of cell line, but IL-27 itself caused varying interferon responses dependent on cell type. However, common to all cell types was the IL-27-stimulated secretion of IL-6 and chemokines IP-10 and MIG. In addition, IL-27 stimulation activated STAT1 and STAT3 in HeLa and T98G cells, suggesting that IL-27 engages the STAT1/3 pathway, which then leads to the upregulation of IL-6, IP-10, and MIG.
