Abstract

The aim of this study was to investigate the differential gene expression of cytokines in peripheral blood mononuclear cells (PBMCs) from patients with pulmonary embolism (PE) and controls. Twenty patients with PE and twenty control patients matched for gender and age with the PE group were recruited into the study. Human cDNA microarray analysis was used to detect differences in the expression of cytokine-associated genes between the two groups. In PE patients, the expression levels of the genes encoding IFNα5, IFNα6, IFNα8, IFNα14, IFNκ, IFNω1, IFNε1 and IFNγ were significantly lower compared with controls (P<0.05). The expression levels of the genes encoding IL1α, IL2, IL3, IL9, IL13, IL17β, IL19, IL22, IL23α, IL24, IL25 and IL31 were significantly lower (P<0.05), while IL10 and IL28A mRNA expression levels were higher in PE patients compared with controls (P<0.05). In PE patients, Cxcl1, Cxcl2, Cxcl6, Cxcl13 and Cxcl14 mRNAs were significantly upregulated (P<0.05), however, Cxcl10 mRNA was significantly downregulated (P<0.01). In PE patients, the mRNA expression levels of TNF superfamily members 1, 9 and 13, and TNF receptor superfamily members 1A, 1B, 9, 10B, 10C, 10D and 19L, were significantly upregulated (P<0.05), whereas TNF receptor superfamily members 11B, 19 and 25 were significantly downregulated compared with controls (P<0.05). The mRNA expression levels of granulocyte-macrophage colony‑stimulating factor, granulocyte colony-stimulating factor, erythropoietin, thrombopoietin and mast cell growth factor were significantly lower in PE patients compared with controls (P<0.05). In PE patients, the mRNA expression levels of a variety of cytokines were imbalanced and cellular immune function was downregulated compared with controls. Thus, PE patients may be more susceptible to infections caused by viruses, intracellular bacteria and parasites.
