Abstract
Viral mutational escape from CD8(+) cytotoxic T lymphocytes (CTLs) is typically considered to be a dichotomous process and uncommon during chronic HIV-1 infection. Ex vivo passaging of HIV-1 from persons with chronic infection, however, revealed the evolution of many fixed substitutions within and around CTL-targeted regions, with an associated increase in replicative capacity. This indicates an evolution of mutations during chronic HIV-1 infection that trade replicative fitness for incomplete evasion of CTLs, or "partial escape."Entities:
