ABSTRACT
Objectives:
We sought to determine whether the aryl hydrocarbon receptor (AhR) and interleukin (IL)-22 may be involved in the pathogenesis of the peripheral blood mononuclear cells (PBMCs) in allergic asthmatic patients and whether their expression may be related to the severity of the disease.Methods:
Blood samples were obtained from each subject with allergic asthma (n =18), controlled asthma (n =17) and healthy controls (n =12) respectively. The PBMCs were collected for AhR mRNA detection by real-time quantitative polymerase chain reaction (PCR). The plasma was collected for IL-22 protein detection by enzyme-linked immunosorbent assay (ELISA).Results:
The expression of AhR mRNA in PBMCs and IL-22 protein in plasma of patients with allergic asthma were higher than those in controlled asthma cases and healthy controls. The plasma concentrations of IL-22 had negative correlation with the predicted percentage of forced expiratory volume in the first second (FEV1%) and the percentage of FEV1 and forced vital capacity (FEV1/FVC%) and it was positively correlated with the asthma severity score (ASS) of the asthmatics.Conclusion:
Our results suggested that both AhR and IL-22 might be involved in the pathogenesis of allergic asthma in human and the level of IL-22 might have some relationship with the severity of the disease.
