Abstract:This study aimed to investigate the changes of Thl7 response when SOCS3 was overexpressed in CD4 + T cells isolated from a mouse model of chronic Pseudomonas aeruginosa lung infection.A recombinant lentivirus carrying SOCS3 gene was constructed and transfected into CD4+ T cells isolated from the spleens of mouse model.The SOCS3 overexpression in cells was confirmed by Western blotting and real-time PCR.Then the CD4+ T cells were stimulated with IL-23,and the expression of p-STAT3 was examined by Western blotting.The mRNA level of RORγt was examined by real-time PCR.The number of IL-17+ cells was analyzed by flow cytometry,and the level of IL-17 was assessed by ELISA.Data showed that SOCS3 overexpression significantly downregulated the levels of p-STAT3 protein and RORγt mRNA in CD4+ T cell;the number of IL-17+ cells and the level of IL-17 protein was significantly decreased in SOCS3-overexpressing cells compared with controls.These results of the in vitro study indicated that the overexpression of SOCS3 could suppress the Th17 response in mice with chronic Pseudomonas aeruginosa lung infection.
