^aBAL fluid was collected from six animals per treatment group at 24, 48, 72, 120, 240 h post-bacterial challenge.

^bValues based on six mice per treatment group. Percentage of cells determined by scoring ≥200 cells per mouse sample. Significant differences (P < 0.05) between transfer and no transfer at 0, 24, and 72 h as determined by χ².

^cRecipient animals received injections of 2.0 × 10⁷ cells per mouse i.p.
