FIG. 1.

Frequency of HIV-specific tetramer-positive cells among freshly isolated cells from CSF and blood. (A) Flow cytometric plots of all HLA-B57 tetramer-positive (IW9, KF11, and QW9) stains among seven asymptomatic HIV-infected individuals. (B) Flow cytometric plots from two HIV-infected individuals (10027 and 10031) with non-HLA-B*57 (HLA-B*08 and HLA*A*03, respectively) tetramer responses are shown. Each tetramer stain was performed with 1.0 × 106 freshly isolated cells from blood and 0.5 × 104 to 3.0 × 104 freshly isolated cells from CSF. Numbers in plots represent frequencies of HIV-specific T cells as percentages of CD8+ T cells from CSF and blood.
