Immunodominance in virus-induced CD8(+) T-cell responses is dramatically modified by DNA immunization and is regulated by gamma interferon.

abstract：:DNA vaccines have recently emerged at the forefront of approaches to harness the immune system in the prevention and treatment of viral infections, as well as the prevention and treatment of cancers. However, these vaccines suffer from limited efficacy since they often fail to produce significant antigen-specific CD8(...
