摘要： Interferon-induced transmembrane proteins (IFITMs) are transmembrane proteins induced by interferon that can provide broad-spectrum antiviral activities. However, there are few reports on the antiviral activity of monkey-derived IFITMs. In this study, the IFITM1 and IFITM3 genes of African green monkey (AGM) were cloned and overexpressed in Vero cells, followed by infection with mouse norovirus (MNV) and severe fever with thrombocytopenia syndrome virus (SFTSV). The results showed that monkey IFITM1 and IFITM3 can be stably overexpressed in Vero cells. Both IFITM1 and IFITM3 from AGM could effectively restrict infection by SFTSV, and the viral inhibition rate of IFITM3 was more obvious compared with IFITM1. However, both monkey IFITM1 and IFITM3 had no significant effect on the replication of MNV. These results indicate that different IFITMs have different functions, which may be related to the structure of the host IFITMs and the types of pathogens.
