The invention provides cell lines that are useful for the rapid detection and production of influenza and parainfluenza viruses. In particular, the invention relates to transgenic cells with increased sensitivity to infection by influenza A, influenza B, or parainfluenza 3 viruses, or which are capable of enhanced productivity of infectious virions. The invention is suitable for use in culturing clinical influenza and parainfluenza virus isolates and for the production of influenza and parainfluenza virus for vaccine formulations, as antigen preparations for diagnostic applications, and for screening antiviral drugs.
