Eexpression of Foxp3 and CD4~+CD_(25)~+ Regulation T Cells in Children with Acute Idiopathic Thrombocytopenic Purpura / 实用儿科临床杂志

ABSTRACT

Objective To investigate the amount of CD4+CD_(25)~+ regulation T cells(Tr cells) and the expression of Foxp3 in peripheral blood in children with acute idiopathic thrombocytopenic purpura(AITP),and analyze the relationship between CD4+CD_(25)~+ Tr cells and the immunopathogenesis of AITP.Methods CD4+CD_(25)~+ Tr cells were detected by flow cytometry in peripheral blood from AITP children and health children.Besides,related cytokine in peripheral blood were assigned by enzyme linked immunosorbent assay(ELISA).The expression of Foxp3 were detected by reverse transcriptase-polymerase chain reaction(RT-PCR).Results CD4+CD_(25)~+ Tr cells decreased obviously in peripheral blood in children compared with that of control group [(2.83?1.05)% vs (5.07?0.59)%,P
