Background and Aims: Graves’ disease (GD) and orbitopathy (GO) are characterised by the presence of pathological anti-thyrotropin receptor antibodies. In thyroid autoimmunity, especially GD and GO, a dysregulation of several T cell subpopulations has been proposed, especially T regulatory (Treg) and T helper 17 (Th17) cells, determining (auto)immunity inhibition and enhancement, respectively. T follicular cells (Tf) within germinal centres (GC: aggregates of lymphocytes w...

Objectives: In Graves’ disease (GD) and Graves’ orbitopathy (GO) self-reactive lymphocytes escape immune tolerance, although the underlying mechanisms are not fully understood. We aimed to characterize the immune signatures of target tissue-resident lymphocytes in relation to GD and GO.Methods: Lymphocytes were derived from blood and ultrasound-guided-fine-needle aspiration (US-FNA) of thyroid and neck lymph nodes (LNs) of the following patient...
