Introduction: T regulatory lymphocytes (Tregs) are defined as CD4+CD25high T lymphocytes and are thought to regulate immune tolerance. The Foxp3 protein level in Tregs is proportional to CD25 protein surface expression and regulatory function, but inversely proportional to IL-7R (CD127) level, the receptor for the growth and survival of T cells. We investigated possible differences in Tregs between newly diagnosed type 1 diabetes (DM1) patients and contro...

Introduction-objective: Fas-mediated thyroid cell apoptosis is differentially regulated in autoimmune thyroid disease (AITD) being up-regulated in Hashimoto’s thyroiditis (HT) and down-regulated in Graves’ disease (GD). The soluble form of Fas (sFas), lacking the transmembrane domain due to alternative splicing may inhibit apoptosis by binding to Fas ligand. In this preliminary study we examined whether sFas is also differentially expressed in patients with AITD....

Background: Obesity is associated with chronic low-grade inflammation that contributes to the development of metabolic syndrome (MS). Resistin, produced by neutrophils and monocytes, displays potent proinflammatory properties and has been associated with cardiometabolic disease. The aim of this study was to (a) determine serum resistin levels among obese patients with or without MS and (b) explore the role of the subsets of circulating white blood cells as potential determinan...

Objective: The Fas/Fas ligand (FasL) apoptotic pathway is activated in patients with autoimmune thyroid disease (AITD). It is believed that Fas and FasL expression in intrathyroidal T lymphocytes and thyrocytes is regulated in a manner resulting in thyroid cell apoptosis in Hashimoto’s thyroiditis (HT) or lymphocyte apoptosis in Graves’ disease (GD). The hypothesis that Fas and FasL may be differentially expressed on peripheral lymphocytes in patients with HT and GD ...
