Figure 2. Flow cytometric analysis of CD8+ T lymphocyte recruitment into the airways induced by I-TAC.
I-TAC (5 μg) was injected intratracheally after adoptive transfer of activated CD8+ T lymphocytes 48 hr prior. The BAL was harvested 18 hr later, and CD8+ T lymphocytes were analyzed by flow cytometry after gating on the lymphocyte subpopulation. The percentages of CD8+/CD3+ T cells of total events are shown in the upper right corners.
