Understanding and controlling viral escape in influenza

点击翻译按钮获取中文摘要

Introduction of a new influenza strain into human circulation leads to a rapid global spread of the virus (e.g. H1N1-09 pandemic) due to minimal antibody immunity. Established T-cell immunity towards conserved viral regions promotes rapid recovery. However, the protective immunity exerts pressure on influenza, leading to "escape" mutations. We will unravel how the viral mutants emerge and propose strategies for T cell-based protective immunity and vaccine design against influenza.
