title: [Mechanism of the induction of apoptosis by influenza virus infection].
abstract: Influenza virus-infected HeLa cells show phosphatidylserine externalization, chromatin condensation, increase of membrane permeability, and inactivation of a mitochondrial enzyme(s), which are collectively referred as apoptosis. The amount of cell surface Fas and its ligand increases before the onset of apoptosis and the presence of a Fas-ligand-antagonizing antibody inhibits apoptosis. Since virus-infected cells simultaneously express Fas and Fas-ligand, it is likely that apoptosis is induced when the cells come into contact with each other. We expect that apoptotic death of influenza virus-infected cells contributes to elimination of the virus from host organism.
