Sendai virus (SeV) possesses two surface-glycoproteins, HN and F. During the normal infection cycle, HN-protein mediates receptor binding and F-protein induces membrane fusion. In addition, F-protein is able to interact with the asialoglycoprotein receptor on hepatocytes. HN-deficient SeV are therefore a promising viral hepatocyte-specific gene transfer system. While the initial production of HN-deficient SeV is possible, the amplification to clinical titers is not possible up to now. In this work, an HN-protein expressing helper cell line was successfully developed. This helper cell line will be used to establish a cell-based helper system for the amplification of HN-deficient SeV.
