Influenza virus production cells and influenza virus production method

摘要

PROBLEM TO BE SOLVED: To produce an influenza virus by using an in vitro culturable cell which has a high proliferative ability of the influenza virus and is preferably used for producing an influenza virus for vaccine production. Provide a way to do it. According to the present invention, an influenza virus-producing cell and a TMED2 gene in a chromosome, characterized in that the expression of the TMED2 gene in the chromosome is suppressed and the cell can be cultured in vitro. Influenza virus, which is characterized in that cells whose expression is suppressed and which can be cultured in vitro (excluding cells constituting humans themselves) are infected with the influenza virus and then cultured. It is a production method. [Selection diagram] None
