Analysis of CD25⁺ FoxP3⁺ T cells in the lung parenchyma of <i>M. tuberculosis</i>-infected mice.

<p>(A) Percentages of CD25⁺ FoxP3⁺ cells within the CD4⁺ T-cell subset in lung parenchyma of untreated controls or of mice infected with ≈100 CFU of H37Rv by aerosol route and (B) number of CD4⁺ CD25⁺ FoxP3⁺ cells, in the lung parenchyma of control or <i>M. tuberculosis</i>-infected mice. Results are means±SD of three mice, studied individually. *, statistically significant (Student's <i>t</i> test, <i>p</i><0.02).
