FIG 5.

Comparable numbers of influenza-specific T cells are present in the lungs of nonasthmatic and asthmatic mice following secondary heterologous CA04 virus challenge. Numbers of CD4⁺ (A), CD8⁺ (B), and NP⁺ CD8⁺ (C) T cells were determined in the lungs of nonasthmatic:PR8/CA04 and asthmatic:PR8/CA04 mice on days 3 and 6 post-CA04 challenge. (D) Percentages of CD62L⁻ CD127⁻, CD62L⁺ CD127⁺, and CD62L⁻ CD127⁺ cells within the CD8⁺ T-cell subset on days 3 and 6 post-CA04 challenge. A total of 3 to 9 mice/group were analyzed at each time point. The experiments were repeated at least twice.
