However,a novel B cell subset,named regulatory B cells(Bregs),has been identified.

Primary Cutaneous B-cell Lymphoma:A Case Report;

Current research in regulatory T cell and inflammatory bowel diseases;

Regulatory T cells and gastrointestinal carcinomas;

Advance in the study of CD4~+CD25~+FOXP3~+ regulatory T cell in tumor immune evasion;

To evaluate the significance of the expression of the transcription factor Foxp3 in peripheral regulatory T cells(Treg) of women with unexplained recurrent miscarriage(URM),25 cases of women with URM were underwent for study and 20 normal non-pregnant women were used as control.

As an important subset of regulatory cells,CD4+CD25+ Treg cells have the features of suppressive and anergic to antigen stimulation.

Recent studies suggest that diverse populations of regulatory T cells(Treg)play an important role in regulating T-helper type 2(Th2)responses to allergens,maintaining functional tolerance.

Objective To investigate the suppressive function of T regulatory cell in Alzheimer′s disease (AD) patients.

Changes of T regulatory cells in rats with experimental colitis after drug treatment with SASP and PSL;

Objective To explore the change and function of CD 4 +CD 25 + and CD 8 +CD 28 -T regulatory cells in peripherel blood monocyte cell (PBMC), spleen and colon in rat experimental colitis induced by trinitrobenzenesulfonic acid (TNBS) .

Objective The purpose of this study is to explore the developed mecha- nism of dilated cardiomyopathy (DCM) by investigating the changes of CD4 ~+ CD25 ~+ T cells and CD4 ~+ CD25 ~+ Foxp3~+ T regulatory cells in peripheral blood mononuclear cells from patients with dilated cardiomyopathy .
