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...

The cytoskeletal actin-binding protein filamin A (FLNA) is poorly expressed in adrenocortical carcinomas (ACC) compared to adenomas (ACA), and this might contribute to sustain the increased cell proliferation by downregulating IGF1R expression and its downstream signaling. In mouse neural progenitor cells, increased protein expression levels of the CDK1 kinase Wee1 have been found after loss of FLNA. This protein has a leading role in regulating the G2-M checkpoint and functio...

Background: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic disease (Covid-19) is associated with the onset of thyroid dysfunction via multiple mechanisms. Patients hospitalised for severe Covid-19 disease may develop painless atypical thyroiditis coexisting with non-thyroidal illness syndrome, which determines transient thyrotoxicosis with quick restoration of euthyroidism during the following weeks. However signs of thyroiditis at ultrasound and sci...

Objectives: SARS CoV-2 infections have been associated with the onset of classic subacute thyroiditis (SAT) or atypical SAT, observed in 10-15% of patients hospitalized for severe COVID19 disease (COV-A-SAT) and characterized by absence of neck pain, mild thyrotoxicosis associated with non-thyroidal illness syndrome and thyroiditis-like areas which may persist in the thyroid gland up to 12 months following SARS-CoV-2 infection, despite normalization of thyroid function. Little...

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...
