The Asp358Ala variant in the interleukin-6 receptor (IL-6R) gene has been implicated in asthma, autoimmune and cardiovascular disorders, but its role in other respiratory conditions such as chronic obstructive pulmonary disease (COPD) has not been investigated. The aims of this study were to evaluate whether there is an association between Asp358Ala and COPD or asthma risk, and to explore the role of the Asp358Ala variant in sIL-6R shedding from neutrophils and its pro-inflammatory effects in the lung. We undertook logistic regression using data from the UK Biobank and the ECLIPSE COPD cohort...

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the progressive deterioration of cognitive functions. Its neuropathological features include amyloid-β (Aβ) accumulation, the formation of neurofibrillary tangles, and the loss of neurons and synapses. Neuroinflammation is a well-established feature of AD pathogenesis, and a better understanding of its mechanisms could facilitate the development of new therapeutic approaches. Recent studies in transgenic mouse models of AD have shown that neutrophils adhere to blood vessels and migrate inside the parenchyma...

Among a broad spectrum of medical treatments, protein therapeutics holds tremendous opportunities for the treatment of metabolic disorders, cancer, autoimmune diseases and etc. Broad adaption of protein therapeutics, however, still remain challenging, not only because of poor protein stability, but they also experience fast clearance after administrated and elicit immune responses, resulting in undesirable biodistribution and short blood residence time. In this study, we demonstrate a novel protein delivery method via encapsulating therapeutic proteins within thin shells of poly(N-vinylpyrrolidone) (PVP), which leads to significantly improved protein stability, reduced macrophage uptake, prolonged circulation time and reduced immunogenicity...

OBJECTIVES: Deregulated production of interleukin (IL)-17 and IL-21 contributes to the pathogenesis of autoimmune disorders such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Production of IL-17 and IL-21 can be regulated by ROCK2, one of the two Rho kinases. Increased ROCK activation was previously observed in an SLE cohort. Here, we evaluated ROCK activity in a new SLE cohort, and an RA cohort, and assessed the ability of distinct inhibitors of the ROCK pathway to suppress production of IL-17 and IL-21 by SLE T cells or human Th17 cells...

OBJECTIVES: To characterize the T cell subsets producing interleukin 17 (IL-17) isoforms A and F in hypertensive kidneys and vessels and determine whether inhibition of IL-17 signaling lowers blood pressure and end-organ damage in a mouse model of hypertension. BACKGROUND: T cell derived cytokines play a central role in the pathophysiology of hypertension and contribute to end-organ dysfunction. We previously showed that mice genetically deficient in IL-17A exhibited blunted hypertension and reduced renal and vascular dysfunction in response to angiotensin II (Ang II) infusion...

Developing a new and effective therapeutic approach against multiple sclerosis (MS) is always an important area of research. RNS60 is a bioactive aqueous solution generated by subjecting normal saline to Taylor-Couette-Poiseuille flow under elevated oxygen pressure. Recently we have demonstrated that RNS60, administered through intraperitoneal injection, ameliorated clinical symptoms and disease progression of experimental allergic encephalomyelitis (EAE), an animal model of MS. Since the intravenous route is not preferred for treating a chronic condition, we tested if nebulization of RNS60 could attenuate the disease process of adoptively-transferred EAE in mice...

INTRODUCTION: Morphea (localized scleroderma) is a relatively rare disease characterized by excessive skin fibrosis. Human endogenous retroviruses (HERV) are largely distributed within the human genome with hundreds of thousands of elements. The HERV have been widely studied in autoimmune disorders, yet hardly ever assessed in diseases with a good prognosis such as morphea. AIM: In this study we focus on the possible relations between the expression of chosen HERV and factors influencing the pathomechanism of the disease, such as age, sex, titres of anti-nuclear antibodies, as well as duration, activity, and severity of the disease (LoSSI index)...

Mesenchymal stem cells (MSCs) possess immuno-regulatory, anti-inflammatory, and pro-angiogenic properties, and therefore have the potential to improve islet engraftment and survival. We assessed the effect human bone marrow derived MSCs have on neonatal porcine islets (NPIs) in vitro and determine islet engraftment and metabolic outcomes when co-transplanted in a mouse model. NPIs co-cultured with MSCs had greater cellular insulin content and increased glucose stimulate insulin secretion. NPIs were co-transplanted with or without MSCs in diabetic B6...

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that predominantly affects women and is associated with prevalent hypertension, renal injury, and cardiovascular disease. Immune system dysfunction is recognized as an important factor in the pathogenesis of hypertension. We recently showed that preventing autoimmunity prevents the development of hypertension in an experimental model of SLE (female NZBWF1 mice). The present study tests the hypothesis that mycophenolate mofetil (MMF), an immunosuppressive therapy used clinically to treat SLE by depleting proliferating B and T lymphocytes, can improve blood pressure control...

PRES is a neurological syndrome characterised by reversible subcortical vasogenic brain oedema in patients with acute neurological signs and symptoms. It occurs in the context of fluctuations in blood pressure, renal failure, autoimmune disorders, eclamptic syndromes and with use of cytotoxic drugs. We present the case of a 60year old female with advanced bowel cancer who was admitted with seizures and sub-arachnoid haemorrhage, with radiographic features of PRES, shortly after receiving bevacizumab (Avastin), a VEGF-inhibitor...

Salivary glands are frequent sites of manifestations of autoimmune disorders in the head and neck. Sjögren syndrome, sarcoidosis, granulomatosis with polyangiitis, and IgG4-related sialadenitis represent the most important autoimmune salivary gland disorders. Due to the lack of specific symptoms, diagnosis of these conditions remains a challenge. Diagnosis is usually based on classification criteria involving clinical tests, histopathological evaluation, and serological examinations. Depending on the disease, biomarkers are of different value and have to be interpreted carefully...

1,2-Dihydro-4-hydroxy-2-oxo-1,8-naphthyridine-3-carboxamide derivative VL15 has been recently developed as a selective cannabinoid CB2 receptor compound. Given the high selectivity of this compound at the cannabinoid CB2 receptor and the well-known protective function of this receptor in neurological disorders with autoimmune component like multiple sclerosis, we assessed the immunomodulatory properties of VL15. We assessed on activated peripheral blood mononuclear cells), proliferation and viability, cell cycle progression and measured activation markers and the expression of phosphorylated proteins...

Complement system homeostasis is important for host self-protection and anti-microbial immune surveillance, and recent research indicates roles in tissue development and remodelling. Complement also appears to have several points of interaction with the blood coagulation system. Deficiency and altered function due to gene mutations and polymorphisms in complement effectors and regulators, including Factor H, have been associated with familial and sporadic autoimmune inflammatory - thrombotic disorders, in which autoantibodies play a part...

Celiac disease (CD) is a severe genetic autoimmune disorder, affecting about one in 100 people, where the ingestion of gluten leads to damage in the small intestine. Diagnosing CD is quite complex and requires blood tests and intestinal biopsy examinations. Controversy exists regarding making the diagnosis without biopsy, due to the large spectrum of manifesting symptoms; furthermore, small-intestinal gastroscopy examinations have a relatively complex management in the pediatric population. To identify novel molecular markers useful to increase the sensitivity and specificity in the diagnosis of pediatric CD patients, the expression levels of two key autophagy executor genes (ATG7 and BECN1) and their regulatory validated miRNAs (miR-17 and miR-30a, respectively) were analyzed by relative quantitative real-time-PCR on a cohort of confirmed CD patients compared to age-related controls...

A 67-year-old man presented with a 3-day history of abdominal pain, fever, and significant weight loss over 2 months. Physical examination revealed left upper quadrant tenderness, hepatomegaly, splenomegaly, and bilateral pitting edema but peripheral lymphadenopathy was absent. Laboratory tests showed anemia, thrombocytopenia, elevated prothrombin time (PT), partial thromboplastin time (PTT), and increased lactate dehydrogenase (LDH). PTT was corrected completely in mixing study. Further workup for the cause of coagulopathy revealed decreased levels of all clotting factors except factor VIII and increase fibrinogen levels, which ruled out disseminated intravascular coagulation (DIC)...

Posterior reversible encephalopathy syndrome (PRES) is suggested in patients with acute neurological symptoms in the appropriate clinical context, including acute hypertension, blood pressure fluctuations, renal failure, blood transfusion, immunosuppression, autoimmune disorders, and eclampsia. PRES is a clinical syndrome, and refers to a disorder with reversible subcortical vasogenic brain edema caused by endothelial dysfunction, predominantly involving the bilateral parieto-occipital regions. Although the clinical course and prognosis are favorable in most cases, intracranial hemorrhage and/or restricted diffusion similar to acute infarction could be seen in some lesions on brain magnetic resonance imaging (MRI)...

Folate receptor α (FRα) autoantibodies (FRAAs) are prevalent in Autism Spectrum Disorder (ASD). FRAAs disrupt folate transport across the blood-brain barrier by binding to the FRα. Thyroid dysfunction is frequently found in children with ASD. We measured blocking and binding FRAAs and thyroid stimulating hormone (TSH), free T4 (FT4), total T3 (TT3), reverse T3 (rT3), thyroid releasing hormone (TRH) and other metabolites in 87 children with ASD, 84 of whom also underwent behavior and cognition testing and in 42 of whom FRAAs, TSH and FT4 were measured at two time points...
