Figure Lengend Snippet: Changes in FPR1/2/3 expressions of blood immune cells in COPD patients after 1-year treatment and with various clinical phenotypes. In 10 COPD patients after 1-year treatment, a FPR3 expression of M1 monocyte, b NK cell, and c Th cell, as well as d FPR2 expression on Th cell all showed significant elevation. e COPD patients with a high MMRC dyspnea scale had higher FPR1 expression on neutrophil, while f those with a history of frequent moderate exacerbation in the past 1 year had lower FPR2 expression on neutrophil. g FPR1 expression on neutrophil showed significant reduction after 1-year treatment. h Ex-smokers with COPD had higher FPR3 expression of NK T cell than current smokers with COPD after 1 year treatment. COPD patient receiving oral steroid treatment for more than 3 months had i higher FPR2 expression on Th cell and j higher FPR3 expression of M1 monocyte than those without oral steroid use. *p < 0.05 for comparisons between COPD patients with a specific phenotype and healthy non-smokers by ANOVA test. # p < 0.05 for comparison between COPD patients with and without s specific phenotype by ANOVA test. § p < 0.05 for comparisons between COPD patients with and without a specific management after 1-year follow-up
Article Snippet: (A) Surface markers were measured by simultaneously staining for 30 min at 4 °C with directly conjugated monoclonal antibodies (mAb) as follows: PE Mouse Anti-Human CD56 (BD Pharmingen, USA), PE-CyTM5 Mouse Anti-Human CD3 (BD Pharmingen), CD4-PC7 (Beckman Coulter; USA), CD8-PC7, CD16-PC7, CD14-PC7 (Beckman Coulter), PerCP-Cy5.5 Mouse Anti-Human CD209 (BD Pharmingen), Anti-human CFS-conjugated FPR1 (R&D Systems; USA), PE-conjugated anti-human FPR2 (R&D Systems) or isotype control mAb. (B) For intracellular staining, cells were stained with anti-CD8a-PE-Cyanine5 and incubated with Cytofix/Cytoperm TM for 20 min at 4 °C, and washed with Perm/Wash Buffer.
