Abstract

The aim of the present study was to investigate the roles of type 2 innate lymphoid cells (ILC2s) and interleukin‑33 (IL‑33) in chronic obstructive pulmonary disease (COPD). Serum and peripheral blood mononuclear cells (PBMCs) were isolated from healthy controls and COPD patients. ILC2 cells from the peripheral blood of COPD patients were stimulated with IL‑33 or neutralizing ST2 antibody+IL‑33 in vitro. The cell viability was assessed using a Cell Counting Kit‑8 assay. ELISA was used to detect serum IL‑33 and the levels of IL‑4, IL‑5, IL‑6, IL‑13 and soluble ST2 (sST2) in the culture supernatant. The percentage of ILC2 cells was measured by flow cytometry. The mRNA expression levels of GATA binding protein 3 (GATA3), RAR‑related orphan receptor (ROR)α, ST2 and prostaglandin D2 receptor 2 (CRTH2) were detected by reverse transcription‑quantitative PCR. It was revealed that IL‑33, IL‑5, IL‑6 and IL‑13 were significantly elevated in peripheral blood of patients with COPD. The proportion of ILC2s in peripheral blood of COPD patients was significantly increased, and the expression of RORA and CRTH2 was increased. The proportion of ST2+ ILC2 cells was significantly increased. After 48 h of IL‑33 stimulation in vitro, the ratio of linage‑CD45+CD127+CRTH2+ cells reached a maximum. In addition, the viability of ILC2 cells, the expression levels of RORA, GATA3, ST2 and CRTH2 mRNA and the cytokines IL‑4, IL‑6, IL‑5, IL‑13 and sST2 were significantly increased. These effects were abrogated by treatment with anti‑ST2. In conclusion, IL‑33 is upregulated in the serum of patients with COPD and the proportion of ILC2s among the PBMCs is increased. IL‑33 may promote the proliferation of ILC2 cells and secrete type 2 T‑helper cell cytokines to participate in the immune response in COPD.
