AIMS: We hypothesized that patients with dysregulated type 2 diabetes may be stratified based on routine clinical markers. METHODS: In this retrospective cohort study, diabetes related clinical measures including age at onset, diabetes duration, HbA1c , BMI, HOMA2-β, HOMA2-IR and GAD65 autoantibodies, were used for sub-grouping patients by K-means clustering and for adjusting. Probability of diabetes complications (95% confidence interval), were calculated using logistic regression...

Aiming at the design of an allosteric modulator of the neonatal Fc receptor (FcRn)-Immunoglobulin G (IgG) interaction, we developed a new methodology including NMR fragment screening, X-ray crystallography, and magic-angle-spinning (MAS) NMR at 100 kHz after sedimentation, exploiting very fast spinning of the nondeuterated soluble 42 kDa receptor construct to obtain resolved proton-detected 2D and 3D NMR spectra. FcRn plays a crucial role in regulation of IgG and serum albumin catabolism. It is a clinically validated drug target for the treatment of autoimmune diseases caused by pathogenic antibodies via the inhibition of its interaction with IgG...

Dear Editor, Gestational pemphigoid (GP) is a rare autoimmune bullous dermatosis in pregnancy. GP usually occurs during the second or third month of pregnancy. It clinically manifests as the development of either early-onset urticarial lesions or late-onset subepidermal blisters that may linger for weeks or even months. Herein we report the case of a 45-year-old woman with the distinctive clinical onset of GP. A forty-five-year-old woman, gravida I, para 0, at 27 weeks gestation, was referred for evaluation to our Department with an extensive pruritic eruption that had developed over the previous 7 days...

Drug-induced lupus erythematosus (DI-LE) is an autoimmune condition secondary to a recent pharmacological intervention. There are no established specific diagnostic criteria for DI-LE, and the disease is recognized based on the medical history of the patient. Typically, the onset is closely related to a recent drug exposure, and the disease terminates after discontinuation of the inducing factor. The most frequent form of DI-LE is drug-induced subacute cutaneous lupus erythematosus (DI-SCLE). There has been an increasing number of drugs which are suspected to provoke SCLE lesions...

Hyposalivation is commonly observed in the autoimmune reaction of Sjögren's syndrome or following radiation injury to the major salivary glands. In these cases, questions remain regarding disease pathogenesis and effective interventions. An optimized technique that allows functional assessment of the salivary glands is invaluable for investigating exocrine gland biology, dysfunction, and therapeutics. Here, we present a step by step approach to performing pilocarpine stimulated saliva secretion, including tracheostomy and the dissection of the three major murine salivary glands...

BACKGROUND: Sloughing esophagitis is an uncommon entity with an unclear pathogenesis characterized by desquamating sheets of squamous mucosa. It has been associated with bullous dermatologic disorders, other autoimmune diseases and has been most commonly reported in elderly, debilitated individuals on multiple medications. CASE REPORT: We report sloughing esophagitis in a previously healthy 17 year-old girl. While the initial trigger of her esophagitis is unclear, she improved with proton pump inhibitor therapy and swallowed fluticasone, with complete resolution after 6 months...

Autoimmunity of the peripheral and central nervous system is an important cause of disease and long-term neurological disability. Autoantibodies can target both intracellular and extracellular neuronal epitopes. Autoantibodies that target cell-surface epitopes infer pathogenicity through several distinct mechanisms, while patients often respond to immunotherapy. However, the underlying pathogenesis of these autoantibodies is yet to be fully understood. Human stem cell-based disease modeling, and the rise of induced pluripotent stem cell technology in particular, has revolutionized the fields of disease modeling and therapeutic screening for neurological disorders...

A 64-year-old man was admitted with acute onset disturbed consciousness. Cerebrospinal fluid analysis revealed pleocytosis and elevated protein, with negative cultures and PCR. Serum antibodies for autoimmune encephalitis were also negative. Brain magnetic resonance imaging (MRI) was unremarkable, but whole-body CT scan showed a tumor in the left lower lung lobe. Bronchial brush cytology demonstrated clusters of malignant cells, and 18 F-fluorodeoxyglucose positron emission tomography showed multiple lesions and increased uptake in the lung tumor...

REVIEW

Numerous studies suggest that infants delivered by cesarean section are at a greater risk of non-communicable diseases than their vaginal counterparts. In particular, epidemiological studies have linked Cesarean delivery with increased rates of asthma, allergies, autoimmune disorders, and obesity. Mode of delivery has also been associated with differences in the infant microbiome. It has been suggested that these differences are attributable to the "bacterial baptism" of vaginal birth, which is bypassed in cesarean deliveries, and that the abnormal establishment of the early-life microbiome is the mediator of later-life adverse outcomes observed in cesarean delivered infants...

B lymphocytes are key players in humoral immunity, expressing diverse surface immunoglobulin receptors directed against specific antigenic epitopes. The development and profile of distinct subpopulations have gained awareness in the setting of primary immunodeficiency disorders, primary or secondary autoimmunity and as therapeutic targets of specific antibodies in various diseases. The major B cell subpopulations in peripheral blood include naïve (CD19+ or CD20+ IgD+ CD27- ), non-switched memory (CD19+ or CD20+ IgD+ CD27+ ) and switched memory B cells (CD19+ or CD20+ IgD- CD27+ )...

Portal hypertension is one cause and a part of a dynamic process triggered by chronic liver disease, mostly induced by alcohol or incorrect nutrition and less often by viral infections and autoimmune or genetic disease. Adequate staging - continuously modified by current knowledge - should guide the prevention and treatment of portal hypertension with defined endpoints. The main goals are interruption of etiology and prevention of complications followed, if necessary, by treatment of these. For the past few decades, shunts, mostly as intrahepatic stent bypass between portal and hepatic vein branches, have played an important role in the prevention of recurrent bleeding and ascites formation, although their impact on survival remains ambiguous...

Elucidation of novel peptides presented by human leukocyte antigen (HLA) class I alleles by immunopeptidomics constitutes a powerful approach that can inform the rational design of CD8+ T cell inducing vaccines to control infection with pathogens such as human immunodeficiency virus type 1 (HIV-1) or to combat tumors. Recent advances in the sensitivity of liquid chromatography tandem mass spectrometry instrumentation have facilitated the discovery of thousands of natural HLA-restricted peptides in a single measurement...

Over the recent years, much has been unraveled about the pro-inflammatory properties of various mitochondrial molecules once they are leaving the mitochondrial compartment. On entering the cytoplasm or the extracellular space, mitochondrial DAMPs (also known as mitochondrial alarmins) can become pro-inflammatory and initiate innate and adaptive immune responses by activating cell surface and intracellular receptors. Current evidence indicates that uncontrolled and excessive release of mitochondrial DAMPs is associated with severity, has prognosis value in human diseases, and contributes to the dysregulated process observed in numerous inflammatory and autoimmune conditions, as well as in ischemic heart disease and cancer...

An 81-year-old Japanese man presented with constitutional symptoms and anemia and was diagnosed with giant cell arteritis (GCA) and myelodysplastic syndrome (MDS) simultaneously. His symptoms and anemia improved promptly with steroids; however, the MDS rapidly progressed to overt leukemia. While MDS patients are at an increased risk of autoimmune diseases, an association with GCA has rarely been reported. This case illustrates the importance of considering GCA as a cause of anemia in elderly patients if MDS is already diagnosed, even in countries where the prevalence of GCA is very low...

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint tissue inflammation. Cyanidin-3-glucoside (C3G) is a major component in the flavonoid family and has shown anti-inflammatory, anti-oxidant and anti-tumor activity. In this study, we investigated the effects of C3G on lipopolysaccharides (LPS)-induced inflammation on human rheumatoid fibroblast-like synoviocytes (FLS) and on collagen-induced arthritis (CIA) mice model. We treated FLS with C3G followed by LPS induction, the expressions of tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β) and IL-6 and the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathway were analyzed...
