Graves patients with high sCTLA-4 level are at risk of severe ophthalmopathy

Daroszewski Jacek , Pawlak Edyta , Karabon Lidia , Bolanowski Marek , Jonkisz Anna , Frydecka Irena

Objectives: Graves' disease (GD) is an autoimmune disease caused by combination of environmental and genetic factors. The CTLA-4 gene is a candidate gene for conferring susceptibility to thyroid autoimmunity. Increased serum level of soluble isoform of CTLA-4 molecule (sCTLA-4), resulting by alternative splicing, was found in some autoimmune diseases. The role of this molecule in the pathomechanism of autoimmunity has not been defined.The principa...

Polymorphisms within genes encoding co-stimulatory molecules modulate the susceptibility to Graves' disease and orbitopathy

Daroszewski Jacek , Pawlak-Adamska Edyta , Przemyslaw Janusz , Frydecka Irena , Karabon Lidia , Jonkisz Anna , Tomkiewicz Anna , Partyka Anna , Lebioda Arleta , Bolanowski Marek

The clinical presentation of GravesÂ’ disease (GD) depends on the combination of environmental and genetic factors. The CTLA-4 and CD28, ICOS genes encoding negative and positive regulator of the T-lymphocyte immune response, are candidate genes for conferring susceptibility to thyroid autoimmunity.Polymorphisms in genes: CTLA-4: g.319C>T (rs5742909), c.49A>G (rs231775), g.*642AT(8_33), CT60 (g.*6230G>A, rs3087243), Jo31...

Background: CTLA-4 polymorphisms have been widely examined for their associations with autoimmune thyroid diseases (GravesÂ’ disease [GD] and Hashimoto thyroiditis [HT]) but their relative population effect remains unclear.Methodology/Principal findings: Meta-analyses of group-level data from 32 (n=11.019 subjects) and 12 (n=4.479) published and unpublished studies were performed for the association of the A49G polymorphism with ...
