Relationship of the Content of Systemic and Endobronchial Soluble Molecules of CD25, CD38, CD8, and HLA-I-CD8 and Lung Function Parameters in COPD Patients

Figure 5

Concentration of sHLA-I-CD8 molecules in blood serum and exhaled breath condensate in COPD patients during exacerbation and in a stable period. Data are presented as mean ± SD; control: healthy nonsmoking volunteers; II: moderate COPD; III: severe COPD; ex: exacerbation; st: stable phase; versus healthy nonsmokers; ^# versus patients with moderate COPD during the exacerbation; ^{^} versus patients with severe COPD during the exacerbation.
