摘要
HIV-1 accumulates 突變s in and around reactive epitopes to escape recognition and killing by CD8(+) T cells. Measurements of HIV-1 time to escape should therefore provide 資訊 on which parameters are most important for T cell-mediated in vivo control of HIV-1. Primary HIV-1 specific T cell responses were fully mapped in 17 individuals, and the time to 病毒 escape, which ranged from days to years, was measured for each epitope. While higher magnitude of an individual T cell response was associated with more rapid escape, the most significant T cell measure was its relative immunodominance measured in acute infection. This identified subject-level or "vertical" immunodominance as the primary determinant of in vivo CD8(+) T cell pressure in HIV-1 infection. Conversely, escape was slowed significant
