Introduction: Autoimmune Thyroid Diseases (AITD) are one of the most prevalent autoimmune diseases in industrialized countries (5% of population). The two main phenotypes of AITD, Hashimoto thyroiditis (HT) and Graves’ disease (GD), are both characterized by the presence of circulating thyroid antibodies and infiltration by autoreactive lymphocytes in the thyroid gland and sometimes the orbit. One of the most studied mechanisms underlying AITD is the imbalance between imm...

Background: Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) are common disorders with an autoimmune etiology, which are known as autoimmune thyroid diseases (AITD). A specific seasonal pattern of the month of birth has been suggested in several autoimmune disorders, supporting the hypothesis of a link between viral infections and the development of aberrant immune-regulatory mechanisms. However, there are few studies which specifically address this issue in AIT...

Purpose: Although growing evidence supports the role of primary cilia (PC) in the regulation of cancer development, their possible role has not yet been studied in pituitary neuroendocrine tumours (PitNETs). The study of cilia could serve as a diagnostic tool providing new insights into the mechanisms of tumorigenesis and aggressiveness of PitNETs. Methods: A total of 86 patients with PitNETs (28 functioning and 58 non-functioning [NF-PitNETs]) and 12 co...

Introduction: Angiopoietins (ANG) -1 and 2, their receptor TIE2, and the vascular endothelial growth factor (VEGF) are involved in the process of angiogenesis. However, their role in the pathogenesis and development of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is not completely understood. In a previous study of 42 patients with GEP-NET, we observed an elevation of these serum markers, especially in those with metastatic disease. The objective of this study was ...

Context: T regulatory type 1 (Tr1) cells are a subpopulation of T lymphocytes (CD4+CD49+LAG-3+IL-10+) lymphocytes that exerts a significant immunosuppressive effect. However, its possible role in autoimmune thyroid disease (AITD) had not been explored so far.Objective: To analyze the levels and function of Tr1 cells in peripheral blood and thyroid tissue of patients with AITD.Design: Cases and controls, observational study.<p c...

Introduction: Autoimmune thyroid diseases (AITD) such as Graves’ disease (GD) or Hashimoto’s thyroiditis (HT) are autoimmune, organ-specific diseases probably related to a complex and multifactorial interplay of specific susceptibility genes and environmental exposures. T lymphocytes and their secretory cytokines play indispensable roles in disrupting tolerance. However, their roles are often complex and full of interactions among distinct components of the thyroid e...

Context: Pathological transcriptomic landscape has been the driver of the Molecular Biology in the recent years. Massive RNA sequencing techniques have been extended from bulk RNAseq, to single cell sequencing (scRNAseq) and spot-based spatial transcriptomics (ST), and sometimes laboratory cannot afford all of them. We tried to answer the question about which would be the best option in thyroid gland using Hashimoto’s thyroiditis (HT) context.Method...

Introduction: Nutritional status in patients with neuroendocrine tumors (NETs), especially with gastroenteropancreatic origin, may be affected and have an impact on prognosis and survival. Different techniques are currently available to assess nutritional status, but not all of them are accessible in routine clinical practice. In this context, Body composition of NET patients was calculated by computed tomography (CT) at L3 level to evaluate its importance on clinical prognosi...

Introduction: Type 2 Diabetes Mellitus (T2DM) is a multifactorial and complex chronic disease characterized by insulin resistance and a dysfunctional adipose tissue. T2DM patients usually present a state of low-grade inflammation due to a dysregulation of the cytokine production. Consequently, this seems to contribute to insulin resistance and beta cell failure associated with the progression of this disease.Objective: To examine expression of Interleuki...
