IFNB1 and infection: An infection experiment will also be conducted in human macrophages and dendritic cells to compare the mRNA and protein levels of gene expression involved in innate immunity, including interleukins (IL), IFN-β, interferon-induced proteins with tetratricopeptide repeats (IFIT), melanoma differentiation-associated protein 5 (MDA-5), tumor necrosis factor alpha (TNF-α), and macrophage inflammatory protein-1 alpha (MIP-1α).
