MX2 and viral infectious disease: We confirmed, by RT-qPCR, that pseudo-SARS-CoV-2 induced type I (IFNβ) and III (IFNλ1) IFNs expression, the first protection against viral infections, as well as the expression of interferon-stimulated genes (IFIT1, TRIM22, and MX2), which counteract viral replication, transcription, and translation in infected and uninfected cells and stimulate the adaptive immune response.
