Figure 2. — Number of alveolar GzmB⁺ (A) and CD8⁺ cells (B) in study subjects. (A) Alveolar GzmB⁺ cells in CLE are significantly greater than that in control or PLE subjects. (B) Number of alveolar CD8⁺ cells in CLE are also significantly greater than that in control or PLE subjects. Correlations between number of alveolar GzmB⁺ cells and FEV₁ (C) and number of alveolar CD8⁺ cells and FEV₁ (D) in CLE subjects. Positive relationship between number of alveolar GzmB⁺ cells and FEV₁ (C) and no relationship between number of alveolar CD8⁺ cells and FEV₁ (D) in CLE subjects. CLE: centrilobular emphysema; FEV₁: postbronchodilator forced expiratory volume in 1 second; GzmB: granzyme B; PLE: panlobular emphysema.
