ABSTRACT
Objective:
To investigate the different function of macrophage between patients with asthma and healthy control , and discuss the pathogenesis of the disease .Methods:
Choose 50 healthy controls ,50 patients with asthma , and isolation of blood mac-rophage.Then samples were induced with GM-CSF, and cells were collected on day 7.Macrophage function was evaluated using the followingmethods:
fluorescence-activated cell sorting analysis for cell surface markers and phagocytosis ;enzyme-linked immunosorbent assay for cytokine production and the induction of T cell .Results:
Compared with the control group , asthma group had decreased CD64, CD11c, CD40 expression, and increased CD206, CD14, CD23 expression(P<0.05);displayed the decreased IL-10 level(P<0.05 );displayed a decreased phagocytosis ability ( P<0.05 );when co-cultured with T cells , the supernatantdisplayed the increased IL-4 expression , and decreased IFN-γlevel ( P<0.05 ) .Conclusion:
Compared with the control group , macrophage in asthma group displayed M2 phenotype, which inditates macrophage play the important role in the pathogenesis of asthma .
