RESUMO
Objective To investigate the relationship between the imbalance of suppressors of cytokine signaling 1(SOCS1)/SOCS3 and abnormal activation of monocytes/ macrophages in children with acute-phase asthma, and explore the molecular mechanism of chronic inflammatory process on airway.Methods The present study enrolled 20 asthmatic children and 20 age-matched normal children. Dual-color flow cytometric analysis was performal to detect the percentage of CD_ 80 、CD_ 86 expressing on CD_ 14 ~+ cell. Reverse transcriptase-polymerase chain reaction and real-time PCR were used to analyze SOCS1,SOCS3 expression in monocytes/ macrophages.Results The proportions of CD_ 80 ,CD_ 86 expressed on CD_ 14 ~+ cell in children with asthma were significantly higher than those in control subjects(CD_ 80 :7.0% vs 1.70%),(CD_ 86 :11.37% vs 2.03%),all P
