We have confirmed the hypermethylation and upregulation of numerous innate immune response genes including IFIH1, TNFAIP3, IFIT1 and IFIT2 following ALKBH5 knockdown during bacterial and viral infections as well as LPS treatment, indicating that these genes might be universally regulated by m6A during bacterial and viral infections. The gene discussed is IFIT2; the disease is viral infectious disease.
