Expansion in both naïve and activated T cells in the BAL fluid after allergen challenge. T cell subsets in the BAL fluid pre- and post-SAC were determined by the expression of CD25 (IL-2R; activated), CD45RA (naïve or effector memory) and CD45RO (memory) by multi-color flow cytometry. The percentages were calculated as a percent of either the CD4+ or CD8+ T cell population. Each subject is represented as a single symbol on the graphs, with p values indicated.
