Importance: For a small percentage of obsessive-compulsive disorder (OCD) cases exhibiting additional neuropsychiatric symptoms, it was proposed that neuroinflammation occurs in the basal ganglia as an autoimmune response to infections. However, it is possible that elevated neuroinflammation, inducible by a diverse range of mechanisms, is important throughout the cortico-striato-thalamo-cortical circuit of OCD. Identifying brain inflammation is possible with the recent advance in positron emission tomography (PET) radioligands that bind to the translocator protein (TSPO)...

FCRL4 is an immunoregulatory receptor that belongs to the Fc receptor-like (FCRL) family. In healthy individuals, FCRL4 is specifically expressed by memory B cells (MBCs) localized in sub-epithelial regions of lymphoid tissues. Expansion of FCRL4+ B cells has been observed in blood and other tissues in various infectious and autoimmune disorders. Currently, the mechanisms involved in pathological FCRL4+ B cell generation are actively studied, but they remain elusive. As in vivo FCRL4+ cells are difficult to access and to isolate, here we developed a culture system to generate in vitro FCRL4+ B cells from purified MBCs upon stimulation with soluble CD40 ligand and/or CpG DNA to mimic T-cell dependent and/or T-cell independent activation, respectively...

Somatic mutations contribute to tumorigenesis. Although these mutations occur in all proliferating cells, their accumulation under non-malignant conditions, such as in autoimmune disorders, has not been investigated. Here, we show that patients with newly diagnosed rheumatoid arthritis have expanded CD8+ T-cell clones; in 20% (5/25) of patients CD8+ T cells, but not CD4+ T cells, harbour somatic mutations. In healthy controls (n=20), only one mutation is identified in the CD8+ T-cell pool. Mutations exist exclusively in the expanded CD8+ effector-memory subset, persist during follow-up, and are predicted to change protein functions...

Myasthenia gravis is a rare long-term neurological condition that is characterised by fluctuating skeletal muscle weakness and fatigue, as well as respiratory difficulties. It is both an acquired autoimmune disease and a chronic neuromuscular disorder. Because of its rarity, myasthenia gravis is relatively unknown and may be unfamiliar to many nurses. While there are various types of myasthenia, this article focuses on myasthenia gravis, exploring its symptoms, diagnosis and treatment, and examining the nurse's role in managing the condition...

Moyamoya disease is a unique occlusive disease of the internal carotid artery(ICA)with moyamoya vessels that can lead to transient ischemic attacks and hemorrhagic stroke. When other inherited or acquired disorders and conditions occur in conjunction with moyamoya disease, the syndrome is known as quasi-moyamoya disease. We report the case of a 34-year-old woman with a past history of SAPHO(Synovitis-Acne-Pustulosis-Hyperostosis-Osteomyelitis)syndrome, who presented with arm weakness and headache. Magnetic resonance angiography revealed severe terminal stenosis of the left ICA with moyamoya vessels, and she was diagnosed as moyamoya disease associated with SAPHO syndrome...

BACKGROUND & AIMS: Sjögren's syndrome and autoimmune pancreatitis (AIP) are disorders with decreased function of salivary, lacrimal glands, and the exocrine pancreas. NOD/ShiLTJ mice and mice transduced with the cytokine BMP6 develop Sjögren's syndrome and chronic pancreatitis and MRL/Mp mice are models of AIP. CFTR is a ductal Cl(-) channel essential for ductal fluid and HCO3(-) secretion. We used these models to ask: is CFTR expression altered in these diseases, does correction of CFTR correct gland function, and most notably, does correcting ductal function correct acinar function...

Autoimmune progesterone dermatitis (APD) is a rare disorder characterized by periodic skin lesions that erupt during the luteal phase of the menstrual cycle. Clinical manifestations of APD is caused by an unusual allergy to progesterone and has a wide range of clinical manifestations from eczema and urticaria to angioedema and erythema multiforme. A 46-year-old woman described recurrent, round erythematous plaques on the lower lip, both forearms and buttocks. These skin eruptions waxed and waned for 10 months, reoccurring 3-4 days before menstruation...

REVIEW

Efforts to understand autoimmunity have been pursued relentlessly for several decades. It has become apparent that the immune system evolved multiple mechanisms for controlling self-reactivity, and defects in one or more of these mechanisms can lead to a breakdown of tolerance. Among the multitude of lesions associated with disease, the most common seem to affect peripheral tolerance rather than central tolerance. The initial trigger for both systemic autoimmune disorders and organ-specific autoimmune disorders probably involves the recognition of self or foreign molecules, especially nucleic acids, by innate sensors...

Thymic stromal lymphopoietin (TSLP) is an interleukin-7 (IL-7) like cytokine that triggers inflammatory responses through activating dendritic cell. It is demonstrated to be involved in a number of disorders, including cancer, gastrointestinal diseases, and autoimmune diseases. In addition, TSLP is also found to be able to induce itch sensation by directly activating the itch sensory neurons. The expression of human TSLP is detected in various tissues such as heart, liver, testis, and prostate. In this study, we report that TSLP was expressed in the human corneal stromal cells, the highly specialized cells that are critical for the function of the cornea...

Rheumatoid arthritis (RA) is a systemic, Th1 cytokine-predominant autoimmune disease result in a chronic and inflammatory disorder. Geniposide (GE), an iridoid glycoside compound that is purified from Gardenia jasminoides Ellis, has antiinflammatory and other immunoregulatory effects, but its exact mechanism of actions on RA is unknown. The aim of this study was to elucidate antiinflammation effects of GE on adjuvant arthritis (AA) rats and its possible immune tolerance mechanisms. Male Sprague-Dawley rats were administered with GE (30, 60, and 120 mg/kg) orally from day 17 to 24 after immunization...

Severe aplastic anemia (SAA) is an autoimmune disease caused mainly by activated T lymphocytes. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of TNF family, which can induce apoptosis and play a significant role in the pathogenesis of many autoimmune disorders. In this study, we sought to investigate the role of TRAIL in peripheral CD8+ T cells (CTLs) from SAA patients to clarify the autoimmune mechanisms of bone marrow failure in SAA. The expression of TRAIL and TRAIL-R2 in CTLs from SAA patients and normal controls were determined by flow cytometry, real-time PCR, and western blot...

Aortitis is a broad term describing inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitides giant cell arteritis and Takayasu arteritis. Other etiologies include aortitis associated with other autoimmune disorders, infectious causes, and paraneoplastic and idiopathic cases. We describe a rare case of a large-vessel arteritis occurring in association with chronic myelomonocytic leukemia (CMML). A 68-year-old female with recent diagnosis of CMML presented to our office for evaluation of abnormal chest computed tomography (CT) that showed inflammation surrounding the entirety of thoracic and abdominal aorta, consistent with aortitis...

Rapid point-of-care, antibody-based testing is not currently available for the diagnosis of most autoimmune and infectious diseases. Here we report a simple, robust and ultrafast fluid-phase immunocapture method for clinical measurements of antibody levels. This method employs neodymium magnetic sticks that capture protein A/G-coated paramagnetic beads bound to antibody-luciferase-labeled antigen complexes. We demonstrate the ability to effectively measure specific antibody levels in serum samples from patients with varied infectious or autoimmune disorders, and in the case of Sjögren's syndrome directly in saliva, requiring about a minute per assay...

BACKGROUND: Preeclampsia is a common pregnancy-specific disorder associated with significant maternal and fetal morbidity and mortality worldwide. It has been proposed that the imbalance between two CD4+ T cell subtypes, regulatory T cells (Treg) and T-helper 17 cells (Th17), is involved in the pathophysiology of preeclampsia. OBJECTIVES: To determine the serum levels of IL-17, IL-21, IL-23 and TGF-β in patients with preeclampsia. METHODS: Blood samples were collected from 30 preeclampsia patients, 30 normotensive pregnant women and 30 healthy individuals with no history of malignancies or autoimmune disorders based on simple sampling...

Childhood-onset systemic lupus erythematosus (cSLE) is a rare, multisystem and potentially life-threatening autoimmune disorder with significant associated morbidity. Evidence-based guidelines are sparse and management is often based on clinical expertise. SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) was launched to optimise and disseminate management regimens for children and young adults with rheumatic diseases like cSLE. Here, we provide evidence-based recommendations for diagnosis and treatment of cSLE...

During RBC transfusion, production of alloantibodies against RBC non-ABO Ags can cause hemolytic transfusion reactions and limit availability of compatible blood products, resulting in anemia-associated morbidity and mortality. Multiple studies have established that certain inflammatory disorders and inflammatory stimuli promote alloimmune responses to RBC Ags. However, the molecular mechanisms underlying these findings are poorly understood. Type I IFNs (IFN-α/β) are induced in inflammatory conditions associated with increased alloimmunization...

Alzheimer's disease (AD) involves changes in both lipid and RNA metabolism, but it remained unknown if these differences associate with AD's cognition and/or post-mortem neuropathology indices. Here, we report RNA-sequencing evidence of inter-related associations between lipid processing, cognition level, and AD neuropathology. In two unrelated cohorts, we identified pathway-enriched facilitation of lipid processing and alternative splicing genes, including the neuronal-enriched NOVA1 and hnRNPA1. Specifically, this association emerged in temporal lobe tissue samples from donors where postmortem evidence demonstrated AD neuropathology, but who presented normal cognition proximate to death...
