Figure 4 Virus-induced chronic obstructive pulmonary disease (COPD) exacerbations showed lower expression of HLA-DR on CD4+ regulatory T cells. The frequency (left) and level (right) of T cell subsets in exacerbation groups, stable COPD group, and healthy smoking group are shown. * P<0.05, **P<0.01, *** P<0.001.
