Aims DX5 + NKT cells’ distribution and population change in BALB/c and FVB mice infected by C sinensis and their function in liver damage were investigated. Methods and results Mice were infected by Clonorchis sinensis metacercariae, and lymphocytes were isolated from the livers, spleens and peripheral blood. NK, DX5 + NKT, INF‐γ + DX5 + NKT cells and liver fibrosis were analysed. The DX5 + NKT cells displayed the largest amount in normal BALB/c mice liver followed by peripheral blood and spleen. Although the hepatic DX5 + NKT cells of BALB/c mice were more than that of FVB mice, they did not show significant percentage change after C sinensis infection. The hepatic DX5 + NKT cells of FVB mice increased remarkably after infection accompanied with heavier liver injury and fibrosis than the BALB/c mice. And hydroxyproline content was also positively correlated with DX5 + NKT cells only in FVB mice. However, the increase of IFN‐γ producing DX5 + NKT cells was lower in FVB mice than in BALB/c mice which showed sharp increase with mild liver damage after infection. The frequencies of anti‐fibrotic NK cells were similar in both of the two mouse strains. Conclusions C sinensis could induce different DX5 + NKT cells responses in different mouse strains which may play roles in liver injury and fibrosis in FVB mice.
