CD4+CD25+T cells in lung tissue. A: CD4+CD25+ T cells expressed as numbers per mg lung tissue after long term smoke exposure and protoporphyrin treatment. Smoke groups are represented by closed symbols and sham smoke groups by open symbols. The significant results of the regression analysis are depicted beneath the figure. B: Example of the flow cytometry analysis: The percentage of CD25 positive cells within the CD4+ T cell population is shown for a PBS (left) and a CoPP (right) smoking mouse.
