Evaluation of Toll-like Receptor 2 Expression on T Lymphocytes in Patients with Graves' Disease in Relation to the Clinical Parameters

Klatka Maria , Grywalska Ewelina , Polak Agnieszka

Introduction: Graves'disease (GD) is a polygenic and multifactorial disease.The innate immune system is a complex network of structured cells and proteins, including the Toll-like receptors (TLRs), which are also expressed on the cells of the adaptive immune system.The aim was to assess the relationship between the expression of TLR-2 on the surface of T CD4+ and CD8+ lymphocytes in pat...

Th17 Cells in Children with Graves’ Disease During Methimazole Treatment

Klatka Maria , Grywalska Ewelina , Rolinski Jacek

Background: Graves’ disease (GD) is the most common cause of hyperthyroidism in the pediatric population. T helper 17 (Th17) IL-17A+CD3+CD4+ cells represent a novel subset of T helper cells that play an active role in inflammatory and autoimmune diseases. Although methimazole (MMI) lowers the levels of thyroid autoantibodies, little is still known about its influence on cell-mediated immune response. The role of Th17 cells in GD pathogenesis remains uncertain and the impa...

Dysregulation of the Immune System in Children with Graves Disease – the Role of NK and NKT-Like Cells

Klatka Maria , Polak Agnieszka , Grywalska Ewelina , Kollataj Witold , Rolinski Jacek

Background: Almost all cases of hyperthyroidism in children result from Graves’ disease (GD). Recent studies have confirmed a significant role of T cells in the development of autoimmune diseases. However, the interactions between NKT-like cells and NK cells in GD are still poorly understood.Objective and hypotheses: The aim of the study was to assess the frequencies of peripheral blood T, NK and NKT-like cells in children with GD.<p class="abst...

Treatment of Graves’ Disease with Methimazole in Children Alters the Proliferation of Treg Cells and T Lymphocytes

Klatka Maria , Grywalska Ewelina , Wasiak Magdalena , Rolinski Jacek

Background: Graves’ disease (GD) is almost always the cause of hyperthyroidism in children. Studies carried out for recent years confirm an important role of T regulatory cells (Tregs) in the development of autoimmune diseases. However, the interactions between T-cell response and Treg proliferation in GD is still poorly understood.Objective and hypotheses: The aim of this research was the assessment of the in vitro proliferation of Treg ce...
