Regulatory T Cells in Renal Disease
نویسندگان
چکیده
Regulatory T cells (Tregs) have a key role in immune homeostasis and in suppressing unwanted inflammatory responses toward self-antigens. Tregs have been implicated in the control of initial activation events, and play roles in limiting proliferation, differentiation and effector functions of T helper cells. However, the activities of Tregs in the development and progression of kidney disease are not fully elucidated. We have demonstrated the potency of Tregs in animal models of kidney disease. In this review, we summarise mechanistic information from rodent models on the roles of Tregs in glomerular immunopathology and discuss the function of Tregs in diverse kidney diseases. Further studies of Tregs should provide important insights into designing of therapeutic strategies to prevent human kidney disease.

Regulatory T Cell Subtypes and TGF-β1 Gene Expression in Chronic Allograft Dysfunction
Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...

Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...
متن کاملNumerical status of CD4+CD25+FoxP3+ and CD8+CD28- regulatory T cells in multiple sclerosis
Objective(s): Regulatory T cells, including CD4+CD25+Fox3+ and CD8+CD28- cells play an important role in regulating the balance between immunity and tolerance. Since multiple sclerosis is an inflammatory autoimmune disease, regulatory T cells are considered to be involved in its pathogenesis. In this study, we investigated the circulatory numbers of the two mentioned types of regulatory T cells...
