ABSTRACT
Objective To investigate the role of interleukin 17 in the differentiation of macrophages from monocyte in vivo and its applicability in Obliterative bronchiolitis (OB).Methods Pathogen-free male C57BL/6 (n =20),IL-17-defcient C57BL/6 (n =10) and BALB/c (n =10) weighing 20-25 g.Weight-matched mice were assigned to three experimental groups.Experimental group ABALB/c (n =5) →C57 BL/6 (n =10).Experimental group BBALB/c (n =5) →IL-17-defcient C57BL/6(n =10).Normal control groupC57BL/6(n =10).The CD80 expression in macrophages in spleens were analysed by flowcytometry 7 days after operation.Native and transplanted lungs were harvested after 14 days and 28 days,stained with HE,and examined under light microscopy.Results Compared to experimental group A,CD80 expression of macrophages reveales a significant decrease in spleen of experimental group B.Furthermore,airway obliteration and destruction of the epithelium in experimental group A were significantly better compared with that of experimental group B on day 14 and 28 after transplantation.Conclusion IL-17 deficiency decreased the polarization of monocytes to macrophages and attenuate the pathology of obliteral bronchiolitis in murine model after trachea transplantaion.
