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) ...
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...
Background: The development of a maternal immune response to fetal antigens and deficiency in regulatory T-cells (Tregs) may lead to preeclampsia. A plausible explanation for the reduced Treg cell function in women with preeclampsia is the presence of exhausted Treg cells which express CD279 or programmed cell death receptor-1 (PD-1), a negative regulatory molecule associated w...
Aim and Background: it seems that population of regulatory T cells increases in many malignancies leading to suppression of effector immune responses and thereby to progression of the disease. We aimed to assess infiltration of the regulatory T cells into tumor environment in women with breast carcinoma. Methods: in a control-case study, 9 malignant tumor tissues from invasive intraductal breas...
T lymphocytes have been characterized to different subsets such as cytotoxic T, Thelper1 (Th1), Th2, Th3, Th9, Th17, and regulatory T cells. Each of these subsets have specific function which distinct them from other lymphocytes. Regulatory T lymphocytes are effective cells in immune system that play an important role in cancers, autoimmune and infectious diseases. Two main subsets of regulator...
mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...
