Th17 Cell Enhances CD8 T-Cell Cytotoxicity via IL-21 Production in Emphysema Mice

Figure 1

Photomicrographs of haematoxylin and eosin-stained lung tissue of air- and CS-exposed mice at 24 weeks (magnification, ×100). Smoke exposure clearly induced alveolar wall destruction and airspace enlargement in mice. (a) Air-exposed mice, (b) CS-exposed mice. Quantification of pulmonary emphysema. Morphometry of the lungs after chronic (24 weeks) air or CS exposure: (c) DI and (d) Lm values of mice. Results are expressed as means ± SD. 𝑛=10 animals/group; *𝑃<0.001.
