Methods of use of viral vectors to deliver antigen to dendritic cells

摘要

This invention relates to methods and compositions useful for delivering antigens to dendritic cells which are then useful for inducing T antigen specific cytotoxic T lymphocytes. This invention also provides assays for evaluating the activity of cytotoxic T lymphocytes. According to the invention, antigens are provided to dendritic cells using a viral vector such as influenza virus which may be modified to express non-native antigens for presentation to the dendritic cells. The dendritic cells which are infected with the vector are then capable of presenting the antigen and inducing cytotoxic T-lymphocyte activity or may also be used as vaccines.
