Outline of Final Research Achievements

To develop a novel strategy to control virus infection, we studied on a mechanism of viral interference. Interference of Sendai virus infection was established at an early stage of infection such as attachment or penetration. Additionally, viral interference was dependent on the HN protein expression that releases sialic acids (a receptor molecule for Sendai virus) by the sialidase activity and decrease of sialic acid molecules on the cell surface. Rabies virus also showed viral interference at an early stage of infection in spite of lack of a receptor destruction factor similar to that of the HN protein.
From these results, we concluded that a receptor destruction by virus infection is one of a major factor for viral interference.
