  1. aRelative ratio (%) of viable lymphocyte count with or without IL-6 (20 ng/ml) and TGF-β1 (2 ng/ml) stimulated with M. pneumoniae and other antigens. Relative ratio is the mean ± standard deviation (four or five samples per group) of the number of viable lymphocytes at day 4.
  2. bSignificantly different (p < 0.05) from value for cytokine (−), antigen 0 μg/ml by Student’s t-test.
  3. cSignificantly different (p < 0.05) from value for 20 ng/ml of IL-6 and 2 ng/ml of TGF-β1 (+), antigen 0 μg/ml by Dunnett multiple comparison statistical test.
