From: IL-10 producing regulatory B cells are decreased in blood from smokers and COPD patients
Percentages of IL-10 producing B-reg cells and IL6 producing B-eff cells in peripheral blood from healthy controls, smokers, and COPD patients determined by flow cytometry. Percentages of IL-10 producing cells (A–E) and IL-6 producing cells (F–J) within total B lymphocytes and B cell subsets within different groups (healthy controls, smokers without airway obstruction, and COPD patients) are depicted
