Profile of peripheral cells during the course of infection.

Mean ± SEM number of CD4 and CD8 expressing peripheral blood cells from LTNPs (circles) and progressors (squares) during the course of infection. For the LTNP group, all patients are represented at all time points (n = 7). For the progressor group, patients were eliminated from the study with the AIDS diagnosis; therefore, for time points 0, 0.5, and 2 (n = 7), for time point 4 (n = 6), for time point 6 (n = 5), and for time point 8 (n = 2).
