HIV-specific CD8 T-cell activity in uninfected injection drug users is associated with maintenance of seronegativity.

Abstract excerpt

OBJECTIVES: To determine whether HIV-exposed, uninfected subjects (EUs) having HIV-specific effector activity are at a reduced risk for seroconverting compared with EUs with no HIV-specific effector responses. DESIGN: Twenty-eight intravenous drug users (IVDU) with documented risk for HIV infection over a 1-year period were screened for the presence of HIV-specific CD8+ effector cell activity. Group I included 18...
