ABSTRACT
Objective To investigate the role of TIGIT signal in Th1/Th2 balance in the process of Schistosoma japonicum in-fection.Methods Male C57BL/6 mice were infected with cercariae of S.japonicum,and normal uninfected mice served as the controls.The percentages of TIGIT+cells,Ki67+CD3+CD4+TIGIT+cells,Ki67+CD3+CD4+TIGIT-cells,IFN-γ+CD3+CD4+TIGIT+cells,IFN-γ+CD3+CD4+TIGIT- cells,IL-4+CD3+CD4+TIGIT+cells and IL-4+CD3+CD4+TIGIT- cells were evaluated in mouse spleen by flow cytometry.Results The proportion of TIGIT+CD4+T cells was higher in the spleen of S.japonicum-infected mice than in the normal uninfected mice(29.30%±0.70% vs.3.09%±0.50%;t=8.834,P<0.01).However,no significant differ-ence in the percentages of TIGIT+CD8+T cells between the infection group and normal controls(3.61% ± 0.26% vs. 3.58% ± 0.16%;t=0.108,P>0.05),and no significant difference was detected in the percentages of TIGIT+cells in non-T cells be-tween the infection group and controls(1.86%±0.19% vs.1.37%±0.17%;t=1.931,P>0.05).In addition,the proportion of Ki67 in the TIGIT+cells was higher than that in the TIGIT-cells(17.03%±0.64% vs.6.59%±0.37%;t=14.09,P<0.01).The Th2/Th1 ratio was higher in the TIGIT+CD4+T cells than in the TIGIT-CD4+T cells(39.28%±3.75% vs.11.79%±1.64%;t=6.721,P<0.01).Conclusion The TIGIT signaling may be involved in the development of Th2 responses in the mice infected with S.japonicum.
