Vaccinia Virus-Specific CD4+ T Cell Responses Target a Set of Antigens Largely Distinct from Those Targeted by CD8+ T Cell Responses

Abstract excerpt

Recent studies have defined vaccinia virus (VACV)-specific CD8(+) T cell epitopes in mice and humans. However, little is known about the epitope specificities of CD4(+) T cell responses. In this study, we identified 14 I-A(b)-restricted VACV-specific CD4(+) T cell epitopes by screening a large set of 2146 different 15-mer peptides in C57BL/6 mice. These epitopes account for approximately 20% of the total...
