IFIT3 and COVID-19: With regard to the relationship between IFIT3 and viral infection, IFIT3 was found to be differentially expressed in response to infection with RNA viruses (Zhou et al., 2013; Feng et al., 2018) and was considered to have predictive potential for COVID-19 because the expression level can be affected by SARS-CoV-2 infection (Shaath et al., 2020; Gao et al., 2021).
