Treating atherosclerosis with regulatory T cells.

CD4⁺Foxp3⁺ Treg and its ICOS⁺ Subsets in Patients with Myocardial Infarction

Background: Atherosclerosis is a multifactorial disorder with chronic inflammatory conditions in which immune cells play a significant role in its pathogenic process. Regulatory T cells (Treg), as a part of immune system, are involved in controlling autoimmune and inflammatory diseases. Quantitative and/or functional alteration of Tregs has been shown to play an atheroprotective role and may al...

Numerical 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...

T Regulatory Cells Frequency During Maintenance Phase Chemotherapy for Pediatric Acute Lymphoblastic Leukemia

Background: Drugs used in cancer treatment specifically kill T regulatory cells. Objective: To determine different phenotypes of T regulatory cells during the maintenance phase chemotherapy for pediatric acute lymphoblastic leukemia (ALL). Materials: We evaluated the percentages of regulatory T cells by flow cytometry. Soluble CTLA-4 (sCTLA-4) ...

Variations in T-helper 17 and Regulatory T Cells during The Menstrual Cycle in Peripheral Blood of Women with Recurrent Spontaneous Abortion

Resting and Activated Natural Tregs Decrease in the Peripheral Blood of Patients with Atherosclerosis

Background: Atherosclerosis is a chronic inflammatory disease affecting large and medium arteries. CD4+ T cells are known to play a role in the progression of the disease. CD4+CD25+Foxp3+ natural Treg (nTreg) cells seem to have a protective role in the disease and their reduction in acute coronary syndrome is recently shown. Objective: To investigate the frequency of nTreg subsets in the pe...
