Differential cell counts in the BAL fluid after 2S-MALP-2 treatment. At 3 days after instillation of 2.5 μg of 2S-MALP-2, rats were sacrificed, and leukocytes in the BAL fluid were determined as described in Fig. 1. Differentiation of leukocytes was performed by flow cytometry with subset-specific antibodies. Data are means ± the SEM (n = 8 per group). Asterisks indicate significant differences (P < 0.01) from the control vehicle (2-propanol) as calculated by the Mann-Whitney U test.
