Abstract Introduction: Human cytomegalovirus (HCMV) is reported to be involved in the occurrence of many human diseases. To further investigate the biological changes of HCMV, we analyzed the relevant factors that affect the autophagy caused by HCMV infection. Methods: Firstly, we cultured human embryonic lung fibroblasts (HELF) cells with HCMV infection, and evaluated the effects of HELF cells infected with different viruses through Enzyme-linked immunoabsorbent assay (ELISA), Real-time quantitative Polymerase Chain Reaction (RT-qPCR), Acridine orange (AO) staining and Western blotting (WB) experiments. Results: Through the above experiments, we found that the combined treatment of HCMV infection and carbamazepine, rapamycin and si-mTOR… More >

Abstract As a response factor of interferon, tripartite motif (TRIM) 22 was reported to exert antiviral activity against viruses. In this study, THP-1 macrophages were infected with human cytomegalovirus (HCMV) to establish the HCMV lytic infection model. The mRNA levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and interferonbeta (IFN-β) were significantly up-regulated in THP-1 macrophages at different infection time and titers. Moreover, for the first time, upregulation of TRIM22 expression was found during HCMV infection at both mRNA and protein levels in THP-1 macrophages. Furthermore, IFN-β could induce TRIM22 expression in THP-1 macrophages or HCMV infected THP-1 macrophages. Depletion of… More >
