Evaluation of cytokine gene expression after avian influenza virus infection in avian cell lines and primary cell cultures [abstract]. American Association of Avian Pathologists Annual Meeting, July 16-19, 2011, St. Louis, Missouri. CD-ROM. Technical Abstract: The innate immune responses elicited by avian influenza virus (AIV) infection has been studied by measuring cytokine gene expression by relative real time PCR (rRT-PCR) in vitro, using both cell lines and primary cell cultures. Continuous cell lines offer advantages over the use of primary cell cultures, but it’s not clear if the results are comparable when studying the innate immune responses to virus infection. In this study, minor differences in cytokine gene expression and in viral replication were found when comparing two chicken-origin cell lines, DF-1 (fibroblast) and HD-11 (macrophage), to two primary cell cultures, chicken embryo fibroblast (CEF) and peripheral blood mononuclear cells (PBMC) when examined at 2, 8, and 24 hours post infection with a low pathogenic avian influenza virus, TK/WI/68 (H5N9).
