Abstract

The regulatory mechanisms of systemic infl ammation in chronic obstructive pulmonary disease (COPD) are not well understood. The aim is to establish the features of immunosuppressive reactions in COPD patients. The study included 112 patients with stable mild-to-severe COPD and 32 healthy volunteers. Cytokine levels (IL-2, IL-4, IL-6, IL-10, IL-17, TNF-α, IFN-γ) and T-regulatory cell (Treg) number were determined using fl ow cytometry. A decrease in Treg number has been foundinsevere COPD. The mechanism of this process may be their competitive interaction with T helper (Th) 17 cells, which is mediated by IL-6action. Ultimately, it contributes to Th17/Treg disbalance and the switching of Th1 immune response to Th17, leading to worsening COPD.
