Objective To compare the function of dendritic cells (DCs)and T lymphocytes (TCs)in different stages of hepatitis B virus related acute on chronic liver failure (HBV-ACLF)patients,and elaborate the potential roles of DCs-TCs in cell immunological mechanism of the pathogenesis of HBV-ACLF.Methods HBV-ACLF patients were divided into two groups,including early stage group,and middle and advanced stage group.A healthy control group was set as well. DCs and TCs were separated and cultured in vitro from peripheral blood mononuclear cells (PBMCs)in peripheral blood. Flow cytometry was used to detect the expressions of surface molecules of DCs including HLA-DR,CD80,CD86,CD83, CD1α,and surface molecules of TCs including CD3 +,CD4+,CD8 +;IFN-α,and IL-4 levels in supernatant of DCs,to demonstrate whether there were differences in inflammatory cytokines and immune cells expressions between different stages of HBV-ACLF.Results Compared with those in healthy people,expression rates of DCs phenotype HLA-DR,CD1α, CD83,CD80 and CD86 in patients with HBV-ACLF were significantly decreased(t =5.3356,13.269,10.8742,13.3685and 23.021 ,respectively,P <0.01),while excreted factor IFN-αhad a significant rise(t =16.4569,P <0.01 );expression rates of TCs phenotype CD3 +,CD4 + and CD4 +/CD8 + were significantly decreased(t =7.4441 ,12.5557,11 .0771 , respectively,P <0.01 ),while percentage of TCs phenotype CD8 + was significantly increased(t =4.4359,P <0.01 ). Compared with early stage group,middle and advanced stage group showed significantly lower expression rates of CD83 and CD86(P =0.0000,0.0057),as well as lower expression rates of TCs phenotype CD4+ and CD4+/ CD8 +(P =0.0268, 0.0002).There was a significantly higher level of IFN-α in early stage (P =0.0000)than that in middle and advanced stage,while IL-4 showed opposite(P =0.0000).Conclusion DCs and TCs in patients with HBV-ACLF in different stages all showed a low immune function,especially in the middle and advanced stage.Pro-inflammatory and anti-inflammatory cytokines function disorder existed in the whole process of HBV-ACLF.The inflammatory factor of early stage had an excessive release while anti-inflammatory cytokine expression in middle and advanced stage was enhanced.
