AIM: To investigate the association of alleles of the 3' immunoglobulin heavy-chain regulatory region 1 (3'RR-1) enhancer hs1.2 in patients with type 1 diabetes (T1D). METHODS: Eighty-one patients with T1D [among which 12 had concomitant coeliac disease (CD) and 25 an autoimmune thyroid disease (AITD)] were compared to 248 healthy individuals. All subjects were recruited from the same geographical area. Blood samples were collected from all patients and a nested PCR was performed to amplify the core of the 3'RR-1 and detect the alleles of the hs1...

Cutaneous mucinoses refer to disorders with abnormal accumulation of mucin in the skin. Mucin is an amorphous material that is a part of the extracellular matrix in dermis. Cutaneous mucinoses could be primary or secondary. The latter is associated with systemic disorders such as autoimmune diseases, diabetes mellitus, paraproteinemia, or altered thyroid function. Here, we report an adult female patient with trauma-induced cutaneous focal nodular mucinoses on left-sided scapular region. Histology showed replacement of collagen bundles by mucinous deposits in superficial and mid-dermis...

Glucagon-like peptide 1 receptor agonists (GLP-1RA) are the newest treatment for diabetes mellitus (DM). These drugs can down-regulate fasting glucose more than oral drugs and lead to more constant glucose levels compared to regular insulin. Acute pancreatitis is a serious condition that may have a fatal outcome. It has been shown that long term and high doses of GLP-1RA can cause pancreatic changes in animals, but no connection has been proven in humans. We present the case of a 67 years old man with DM treated with oral drugs for 10 years until 3 months before, when GLP-1RA was added...

PURPOSE OF REVIEW: The autoimmune ecology refers to the interactions between individuals and their environment leading to a breakdown in immune tolerance and, therefore, to the development of one or more autoimmune diseases in such an individual. Herein, an update is offered on four specific factors associated with autoimmune diseases, namely, vitamin D, smoking, alcohol and coffee consumption from the perspective of exposome and metabolomics. RECENT FINDINGS: Smoking is associated with an increased risk for most of the autoimmune diseases...

Major histocompatibility (MHC) class II molecules are strongly associated with many autoimmune disorders. In type 1 diabetes, the DQ8 molecule is common, confers significant disease risk and is involved in disease pathogenesis. We hypothesized blocking DQ8 antigen presentation would provide therapeutic benefit by preventing recognition of self-peptides by pathogenic T cells. We used the crystal structure of DQ8 to select drug-like small molecules predicted to bind structural pockets in the MHC antigen-binding cleft...

We conducted an experimental database analysis to determine the expression of 61 CD4+ Th subset regulators in human and murine tissues, cells, and in T-regulatory cells (Treg) in physiological and pathological conditions. We made the following significant findings: (1) adipose tissues of diabetic patients with insulin resistance upregulated various Th effector subset regulators; (2) in skin biopsy from patients with psoriasis, and in blood cells from patients with lupus, effector Th subset regulators were more upregulated than downregulated; (3) in rosiglitazone induced failing hearts in ApoE-deficient (KO) mice, various Th subset regulators were upregulated rather than downregulated; (4) aortic endothelial cells activated by proatherogenic stimuli secrete several Th subset-promoting cytokines; (5) in Treg from follicular Th (Tfh)-transcription factor (TF) Bcl6 KO mice, various Th subset regulators were upregulated; whereas in Treg from Th2-TF GATA3 KO mice and HDAC6 KO mice, various Th subset regulators were downregulated, suggesting that Bcl6 inhibits, GATA3 and HDAC6 promote, Treg plasticity; and (6) GATA3 KO, and Bcl6 KO Treg upregulated MHC II molecules and T cell co-stimulation receptors, suggesting that GATA3 and BCL6 inhibit Treg from becoming novel APC-Treg...

CD44 variant (CD44v) contributes to cancer stemness by stabilizing the xCT subunit of system xc(-) and thereby promoting its glutamate-cystine antiporter activity. CD44 has also been implicated in autoimmune insulitis and inflammation in diabetic islets, but whether CD44v regulates insulin secretion has remained unclear. Here we show that CD44v inhibits insulin secretion by attenuating amino acid transport mediated by the L-type amino acid transporter LAT1. CD44v expression level was inversely related to insulin content in islets of normal and diabetic model mice...

Individuals with type 1 diabetes (T1D) are at increased risk of coeliac disease (CD), autoimmune thyroiditis and autoimmune gastritis, but the absolute risks are unclear. The aim of this study was to investigate the prevalence of autoantibodies to tissue transglutaminase (TGA), thyroid peroxidase (TPOA), and gastric H+ /K+ -ATPase (ATPA) and their genetic associations in a well-characterised population-based cohort of individuals with T1D from the Bart's-Oxford family study for whom islet autoantibody prevalence data were already available...

ILDR2 is a member of the Ig superfamily, which is implicated in tricellular tight junctions, and has a putative role in pancreatic islet health and survival. We recently found a novel role for ILDR2 in delivering inhibitory signals to T cells. In this article, we show that short-term treatment with ILDR2-Fc results in long-term durable beneficial effects in the relapsing-remitting experimental autoimmune encephalomyelitis and NOD type 1 diabetes models. ILDR2-Fc also promotes transplant engraftment in a minor mismatch bone marrow transplantation model...

Regulatory T cells (Tregs) represent a cell type that promotes immune tolerance to autologous components and maintains immune system homeostasis. The abnormal function of Tregs is relevant to the pathogenesis of several skin diseases like psoriasis, atopic dermatitis, systemic lupus erythematosus, cutaneous T-cell lymphomas, and skin cancer and is also important in rheumatoid arthritis, diabetes and other autoimmune diseases. In this review, we will summarize the role of mutations and/or polymorphisms of genes involved in Tregs development, and functions in the pathogenesis of selected skin diseases...

BACKGROUND: Gallstone disease is highly prevalent and is associated with systemic inflammation. AIMS: To determine whether screen-detected gallstones or cholecystectomy are associated with the occurrence of autoimmune and autoinflammatory diseases and the most common subgroups thereof. METHODS: A cohort study of three randomly selected general population samples from Copenhagen was performed. Participants (n = 5928) were examined in the period 1982-1992, underwent abdominal ultrasound examination to detect gallstone disease, and followed through national registers until December 2014 (median 24...

Hepatitis C virus (HCV) is able to trigger both hepatic and extra-hepatic manifestations (1,2). Among the latter, the most investigated is mixed cryoglobulinemia vasculitis (MCV), especially of type II (3, 4), usually detected in 40-60% of patients chronically infected with enhanced the risk to develop lymphomas (5). Autoimmune disorders including thyroid disease, and diabetes mellitus have also been associated with chronic HCV infection (6). Skin manifestations may occur in up to 17% of HCV positive patients (7) and are the result of the immuno-mediated damage induced by the virus itself, and/or the associated liver injury (8)...

AIMS/HYPOTHESIS: Identifying individuals suitable for monogenic autoimmunity testing and gene discovery studies is challenging: early-onset type 1 diabetes mellitus can cluster with additional autoimmune diseases due to shared polygenic risk and islet- and other organ-specific autoantibodies are present in both monogenic and polygenic aetiologies. We aimed to assess whether a type 1 diabetes genetic risk score (GRS) could identify monogenic autoimmune diabetes and be useful to prioritise individuals for gene discovery studies...

Type 1 diabetes (T1D) is a chronic disease characterized by an autoimmune-mediated destruction of insulin-producing pancreatic β cells. Environmental factors such as viruses play an important role in the onset of T1D and interact with predisposing genes. Recent data suggest that viral infection of human islets leads to a decrease in insulin production rather than β cell death, suggesting loss of β cell identity. We undertook this study to examine whether viral infection could induce human β cell dedifferentiation...

Type I IFN (IFN-I) dysregulation contributes to type 1 diabetes (T1D) development, and although increased IFN-I signals are pathogenic at the initiation of autoimmune diabetes, IFN-I dysregulation at later pathogenic stages more relevant for therapeutic intervention is not well understood. We discovered that 5 key antigen-presenting cell subsets from adult prediabetic NOD mice have reduced responsiveness to IFN-I that is dominated by a decrease in the tonic-sensitive subset of IFN-I response genes. Blockade of IFNAR1 in prediabetic NOD mice accelerated diabetes and increased Th1 responses...

Diabetes mellitus (DM) is a metabolic disorder of glucose homeostasis caused by insufficient secretion or inadequate action of insulin. Nowadays, the increased morbidity of DM is a worldwide issue. Pancreatic beta cell death plays a key role in the progress of DM, especially Type 1 diabetes (T1D). Traditional biomarkers, such as C-peptide and islet autoimmune antibodies are limited to reflect beta cell death and to identify high risk patients in the clinical practice. Recently, a novel biomarker, differentially methylated circulating DNA, has become a research hotspot...

Type 1 diabetes (T1D) is an autoimmune disease in which insulin-producing beta cells in pancreatic islets are progressively destroyed. Clinical trials of immunotherapies in recently diagnosed T1D patients have only transiently and partially impacted the disease course, suggesting that other approaches are required. Our previous studies have demonstrated that heparan sulfate (HS), a glycosaminoglycan conventionally expressed in extracellular matrix, is present at high levels inside normal mouse beta cells. Intracellular HS was shown to be critical for beta cell survival and protection from oxidative damage...

Although Interleukin-2 (IL-2) was identified almost 40 years ago, only recently low dosage IL-2 therapy is proved to be an effective approach to treat autoimmune diseases. The underlining mechanism is that IL-2 can fine-tune subsets of CD4+ T cells by promoting the development and maintenance of regulatory T cells (Treg) at low-dosage (ld) and enhance the functions of effector T cells (Teff) at high-dosage (hd). Since the successful clinical trials of IL-2 to treat patients with autoimmune diseases and inflammatory conditions, including Systemic lupus erythematosus (SLE) and Type 1 Diabetes (T1D), ld IL-2 therapy is a promising strategy to treat autoimmune diseases...

Bullous pemphigoid (BP) is an acquired autoimmune blistering disease in which autoantibodies against epitopes in the basement membrane zone of the skin such as BP180 or BP230 are produced. Dipeptidyl peptidase (DPP)-4 inhibitors have become commonly used to treat diabetes. As DPP-4 inhibitors are more commonly prescribed for diabetes, BP related to DPP-4 inhibitors has been reported and has attracted attention. Therefore, we retrospectively investigated patients who were diagnosed with BP in order to examine characteristics of DPP-4 inhibitor-related BP (nine patients; median age, 85 years) in comparison with non-DPP-4 inhibitor-related BP (21; median age, 85 years)...
