Abstract:
Objective To explore the association of chemokines and their receptors with immunologi- cal abnormality in newly diagnosed systemic lupus erythematosus(SLE) patients.Methods The serum con- centration of MIP-1?,MIP-1?,RANTES,IFN-?IL-4 were measured by enzyme-linked immunoabsorbent assay (ELISA) in 37 newly diagnosed.SLE patients and 20 normal controls.The expression rate of CCR1, CCR3,CCR5 on CD4~+T cells were detected by flow cytometry in 18 SLE patients and 10 normal controls.Re- suits Serum MIP-1?,MIP-1?concentrations were significantly higher in SLE patients than in normal control group (P＜0.01),the concentration of MIP-1?positively correlated with MIP-1?(r=0.609,P＜0.01);the per- centage of CD4~+CCR1~+ and CD4~+CCR5~+ cell were significantly lower in newly diagnosed SLE patients than in normal control group (both P＜0.01),the percentage of CD4~+CCRI~+ cells correlated negatively with the level of serum MIP-1?and IFN-?r=-0.525,P=-0.017;r=-0.442,P=0.045);the percentage of CD4~+CCR5~+ cell corre- lated negatively with the level of serum IFN-?(r=-0.645,P=0.001);the ratios of CD4~+CCR3~+/CD4~+CCR5~+ was significantly higher in newly diagnosed SLE patients than in the normal control group (P＜0.01).Conclusion Abnormal change and interaction of chemokines and their receptors with cytokines lead to immunologic dys- function and may participate in the initiation of SLE.
