ABSTRACT
Objective:
To understand the expression levels of Tim-3,a new proinflammatory factor in the early stages of Echinococcus granulosus infection in mice.Methods:
BALB/c mice were infected with E.granulosus.Peritoneal macrophages and spleen cells were collected at 1,5,9 and 13 days post-infection.At different time points ,the levels of Tim-3 in peritoneal macrophages and spleen CD3+lymphocyte subsets were detected by FCM , and the relative expression of TLR 4 mRNA was detected by qRT-PCR.Results:
There was no significant difference in the expression levels of Tim-3 of CD3+spleen lymphocyte subsets between E.granulosus group and control group (P>0.05).The expression levels of Tim-3 of spleen macrophages (9,13 days) and peritoneal macrophage (5,9,13 days) were much higher in E.granulosus infected group than those in control group with statistical significance (P<0.05).The numbers of macrophages were no change.Compared with control groups,the relative expression of TLR4 mRNA at 1 day post-infection was statistically higher in E.granulosus infected group ( P<0.05 ).Conclusion:
During early stage of E.granulosus infection in mice,the levels of Tim-3 expression are upregulated,while the expression of TLR4 are downregulated,which may inhibit the function of macrophages resulting in host-immunity-defensive-system inhibition and immune tolerance of E.granulosus to host.
