Figure Lengend Snippet: Different roles of CD4+ and CD8+ T cells in the cytotoxic lysis and release of IFN-γ. The two T-cell populations were isolated by the MACS magnetic kit and showed more than 92% purity by flow cytometry. The individual T-cell populations were cocultured at various concentrations with either strain RB51-infected or normal J774.A1 cells. The cytotoxic activity (A) and the amount of IFN-γ released into the supernatants (B) were measured. The data are means for triplicate estimations, and standard deviations did not exceed 20% of the means. Cocultures of CD4+ T cells with noninfected target macrophages (solid squares) and RB51-pulsed target macrophages (solid triangles) and CD8+ T cells with noninfected target cells (solid diamonds) and RB51-pulsed target cells (solid circles) were tested.

Article Snippet: Briefly, live T cells isolated by Histopaque column purification were incubated with MACS magnetic MicroBeads to which monoclonal antibodies against CD4 molecule (clone GK1.5; isotype, rat IgG2b) or CD8 molecule (clone 53-6.7; isotype, rat IgG2a) had been coupled (Miltenyi Biotec, Auburn, Calif.) at the concentration of 10 μl of MicroBeads per 10 7 total cells for 15 min in a refrigerator at 4°C (see Fig. ).
