Increased Numbers of NK Cells, NKT-Like Cells, and NK Inhibitory Receptors in Peripheral Blood of Patients with Chronic Obstructive Pulmonary Disease

Figure 1

Lymphocyte subsets in COPD patients and HNS. (a) The cells were gated initially on living lymphocytes. At least 50,000 events were analyzed for each sample. Viable lymphocytes were gated on the basis of forward and side angle light scattering characteristics. Data shown are representative charts from different groups of subjects and the frequencies of CD3⁺ T cells, CD4⁺ T cells, CD8⁺ T cells, NK cells, and NKT-like cells in individual subjects. (b), (c), (d), (e), and (f) Summarized data show the number of CD3⁺ T cells, CD3⁺ CD4⁺ T cells, CD3⁺CD8⁺ T cells, CD3⁻CD56⁺ NK cells, and CD3⁺CD56⁺ NKT-like cells in COPD patients and HNS. (g) Summarized data show the CD4⁺/CD8⁺ ratio. The horizontal lines show the median.
