Objectives: Autoimmune diseases are typically studied with a focus on the immune system, and less attention is paid to responses of target tissues exposed to the immune assault. We aimed to evaluate, based on available bulk RNA sequencing data, whether inflammation induces similar molecular signatures in the target tissues of five autoimmune diseases, namely type 1 diabetes (T1D), Hashimoto’s thyroiditis (HT), rheumatoid arthritis (RA), multiple sclerosis (MS) and systemi...

Introduction: miR143 and 145 seem to be involved in the pathogenesis of cortitotrophinomas by modulating the expression of MAPK7 and CCNL1 genes, which protein products are involved in cell proliferation, differentiation, and cell cycle progression. Objective: To analyze the modulation of miR-143 and -145 in the expression of MAPK7 and CCNL1 genes in corticotrophinomas and corticotrophic tumoral lineage (AtT20).Material and Methods: The expression of MAP...

Aim: IFNα is a key regulator of the initial dialogue between pancreatic β-cells and the immune system in type 1 diabetes (T1D). IFNα induces endoplasmic reticulum (ER) stress, insulitis and a massive HLA-ABC overexpression in human β-cells, three histological hallmarks of T1D. Against this background we investigated the global role of IFNα on iPSC-derived islet-like cells, used here to mimic islet cells in the early neonatal period when autoimmunity ag...
