Regulation of in vitro erythropoiesis by normal T cells: evidence for two T-cell subsets with opposing function.

بررسی اثر تماس مستقیم سلولهایT بکر با سلولهای فیبروبلاست تحریک شده با BCG بر القای سلولهایT تنظیمی

Background: Lymph node stromal fibroblasts are interconnected with TCD4+ cells and affect their phenotype and function. Understanding the nature of these interactions under unusual conditions like infections will help to their application in control and regulation of immune responses. Materials and methods: Lymph node fibroblasts were affected in BCG primed immune environment by both in-...

The Immunomodulatory Effect of Cyclophosphamide on Regulation of T-Cell Subsets and Antigen Presenting Cells.

فنوتایپینگ لنفوسیت‌های T خاطره‌ای در گردش در سالک

Background and Aim: The heterogenous population of memory T lymphocytes is distinguished based on surface markers and effector functions such as cytokine secretion. Recently, two subsets of memory T cells are defined by expression of chemokine receptor CCR7 and CD45RA designating as "central memory" T cells (TCM) and "effector memory" T cells (TEM). The objective of this staudy was to evaluate ...

سلول‌های T تنظیمی: انواع، تولید و عملکرد

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...

Induction of T Regulatory Subsets from Naïve CD4+ T Cells after Exposure to Breast Cancer Adipose Derived Stem Cells

Background: Adipose derived stem cells (ASCs) provoke the accumulation and expansion of regulatory T cells, leading to the modulation of immune responses in tumor microenvironment. Objective: To assess the effect of tumoral ASCs on the trend of regulatory T cells differentiation. Methods: Peripheral blood naïve CD4+ T cells were co-cultured with ASCs derived from breast cancer or normal breast ...
