TIPE2 is negatively correlated with tissue factor and thrombospondin-1 expression in patients with bronchial asthma.

The interaction between inflammatory processes and a hypercoagulant state may aggravate the severity of asthma and stimulate the airway remodeling of asthma. The aim of the current study was to evaluate the association between the negative inflammatory regulator tumor necrosis factor α induced protein‑8 like‑2 (TIPE2) and the coagulating substances tissue factor (TF) and thrombospondin‑1 (TSP‑1) in patients with bronchial asthma. Compared with healthy controls, TIPE2 expression was significantly downregulated, whereas TF expression was upregulated in the peripheral blood mononuclear cells (PBMCs) of patients with bronchial asthma. In addition, levels of TF and TSP‑1 in the sera were up‑regulated in patients with asthma compared with healthy controls. TIPE2 expression was negatively correlated with TF in the PBMCs and sera and was negatively correlated with TSP‑1 levels in the sera of patients with bronchial asthma. The results of the current study indicated that anti‑inflammatory TIPE2 levels are associated with levels of the coagulation substances TF and TSP‑1. However, further studies are required to determine whether TIPE2 participates in the pathogenesis of asthma by interacting with the coagulation substances TF and TSP‑1. [ABSTRACT FROM AUTHOR]
