ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of avian influenza virus (AIV) NS1 protein on the expression of interferon-inducible protein 10 (IP-10).</p><p><b>METHODS</b>NSI gene from virus A/Anhui/1/2005 (H5N1), NS1 gene inserted with 80-84 amino acids from virus A/Anhui/1/2005 (H5N1) and NS1 gene from virus A/Puerto Rico/8/1934 (H1N1) were cloned into the eukaryotic expression vector pEGFP-N1, and transfected into BEAS-2B cells, IP-10 expression level in transfected cells was detected by flow cytometry.</p><p><b>RESULTS</b>Compared with the control group pEGFP-N1, expression of these three different NS1 genes can down-regulate the expression of IP-10 in BEAS-2B cells, but there is no significant difference as to the lower level among them.</p><p><b>CONCLUSION</b>NS1 protein of A/Anhui/1/2005 (H5N1) can down-regulate the expression level of IP-10, but this may not clarify its relationship with the virulence of AIV.</p>
