Abstract:
Objective To investigate the changes of dendritic cell subsets and CD 80,CD86 expression in peripher-al blood in patients with immune thrombocytopenia (ITP), and to evaluate the changes of serum interleukin -2(IL-2), serum interleukin-4(IL-4), serum interleukin-10(IL-10) and interferon-γ(IFN-γ) before and after dexam-ethasone treatment, overall, further analyzing the relationship between them and dexamethasone .Methods Collec-ting blood samples of 60 ITP patients and 10 normal controls with heparin anticoagulation , and distribution of den-dritic cell subsets of ITP and normal controls was detected by flow cytometry , and the changes of serum IL-2, IL-4, IL-10 and IFN-γwere detected by enzyme linked immunosorbent assay (ELISA).Results The percentage of DC2 was increased in ITP patients compared with the control group (P <0.05) and there was no statistically significont difference after dexamethasone treatment ; the expressions of CD80 on DC1 and DC2 were increased compared with the control group(P <0.05), as well as the expression of CD86 on DC2 and the percentage of them decreased after treatment.The serum IL-2, IFN-γlevels before the dexamethasone treatment were higher than the normal control group(P <0.05),then decreased after treatment.However, the serum IL-4, IL-10 levels were lower than the nor-mal control group before the treatment (P <0.05), increased after treatment.Conclusion The disorder of the number and function of DCs and the changes of the serum IL -2, IL-4, IL-10 and IFN-γlevels may play important roles in the pathogenesis of ITP.Moreover, there is a probable key relationship between them and the effects of dexamethasone treatment.
