An update on biomarker discovery and use in systemic sclerosis.
Authors: Matsushita T, Takehara K Abstract INTRODUCTION: Systemic sclerosis (SSc) is an autoimmune disease characterized by excessive extracellular matrix deposition in the skin and internal organs. Three major abnormalities, autoimmunity, vasculopathy, and fibrosis, are considered to play important roles in the pathophysiology of SSc. SSc is a heterogeneous disease with clinical features, disease progress, therapeutic response, and prognosis. Therefore, identification of biomarkers, which can predict the course of the disease, is required for the progress of clinical practice. Area covered: This review focuses on ...

Inflammatory Joint Disorders and Neutrophilic Dermatoses: a Comprehensive Review
AbstractRheumatoid arthritis and spondyloarthritis are inflammatory joint disorders with an autoimmune pathogenesis and systemic involvement. The skin is one of the most frequently affected extraarticular sites with a number of manifestations or distinct diseases, including common conditions, such as rheumatoid nodules and psoriasis, and rare diseases like neutrophilic dermatoses. The latter are clinically characterised by polymorphic lesions, including pustules, bullae, abscesses, papules, nodules, plaques and ulcers, and histologically by neutrophil-rich inflammatory infiltrates. Inflammatory joint disorders and neutroph...

Role of TGF- β in Self-Peptide Regulation of Autoimmunity
AbstractTransforming growth factor (TGF)- β has been implicated in regulation of the immune system, including autoimmunity. We have found that TGF-β is readily produced by T cells following immunization with self-peptide epitopes that downregulate autoimmune responses in type 1 diabetes (T1D) prone nonobese diabetic (NOD) mice. These incl ude multiple peptide epitopes derived from the islet β-cell antigens GAD65 (GAD65 p202-221, GAD65 p217-236), GAD67 (GAD67 p210-229, GAD67 p225-244), IGRP (IGRP p123-145, IGRP p195-214) and insulin B-chain (Ins.

Rare presentation of alopecia universalis congenita and twenty-nail dystrophy in siblings
We report a rare case of two siblings with alopecia universalis congenita with twenty-nail dystrophy. To the best of our knowledge, this case is the first case to be reported with such association in both siblings. This case reports highlights the fact that alopecia areata is an autoimmune disease with a genetic predisposition as in our case both siblings had alopecia universalis and nail dystrophy. There was no evidence of any other ectodermal dyplasia and had normal teeth and seat glands. The skin biopsy ruled out congenital atrichia and was suggestive of alopecia areata.

In Vivo Enrichment of Diabetogenic T Cells
We describe a method to enrich and harvest autoimmune T cells in vivo by using a biomaterial scaffold loaded with protein antigens. In model antigen systems, we found that antigen-specific T cells become enriched within scaffolds containing their cognate antigens. When scaffolds containing lysates from an insulin-producing β-cell line were implanted subcutaneously in autoimmune diabetes–prone NOD mice, β-cell–reactive T cells homed to these scaffolds and became enriched. These T cells induced diabetes after adoptive transfer, indicating their pathogenicity. Furthermore, T-cell receptor (TCR) sequencin...

Infection-mediated autoimmune movement disorders
Infectious diseases remain the most common cause of neurological disability in the world. A number of movement disorders can develop in adults and children in response to infections. These can occur in isolation or as part of a broader neurological illness, with movement abnormalities consequent to an encephalopathy or a broader brain dysfunction. While most infection-related movement disorders are direct consequences of an active infectious process affecting cerebral structures implied in the motor network, at times a delayed immune-mediated process in response to a previous infectious is responsible for the neurological ...

We appreciate the interests expressed by Alberto Scir é et al. in our recent publication describing the phenotypic characteristics and natural history of a cohort of patients that fulfill classification criteria for interstitial pneumonia with autoimmune features (IPAF) . In their letter they suggest that the designation of IPAF may be a transient condition and that some patients that initially are classified as IPAF will evolve into a characterizable connective tissue disease (CTD). We agree and believe this should highlight the need for longitudinal surveillance for evolution to characterizable forms of CTD. (S...

Diagnosis and management of diabetes in older people
Abstract The incidence of diabetes has plateaued since 2004, although the prevalence continues to rise. The highest incidence is in people over the age of 70 years, most of whom have type 2 diabetes; a minority have type 1, which can present at any age. Type 1 diabetes may present more slowly in older people, a condition sometimes known as latent autoimmune diabetes in adults (LADA). Older people with diabetes have more than double the risk of cardiovascular disease compared to their non‐diabetic peers, and the risk of diabetes‐related major lower limb amputation is twice as high in those over 75 years compared with th...

Thus, the concept of "blood microbiota" brings about many questions about the nature, origin, and biological significance of the "unusual microbial cohabitants" in human blood. In contrast to current views that bloodstream in healthy humans is sterile, the hypothesis about the existence of microbes as L-forms (cell wall deficient bacteria) in human blood ...

The IL –10/STAT3 axis: Contributions to immune tolerance by thymus and peripherally derived regulatory T‐cells
The signal transducer and activator of transcription (STAT) proteins are important mediators for the integration of extrinsic signals provided by cytokines and hormones and thereby adapt cellular processes to their surroundings. In the past decade, the involvement of STAT3 in the regulation of T‐cell responses has become a topic of increasing interest. STAT3 is activated in response to multiple cytokines, many of which have been shown to influence T‐cell responses. Interestingly, many of these factors have been described with apparent opposing roles, such as the highly pro–inflammatory potency of IL–6 and t...

Abstract The peritoneum defines a confined microenvironment, which is stable under normal conditions, but is exposed to the damaging effect of infections, surgical injuries, and other neoplastic and non‐neoplastic events. Its response to damage includes the recruitment, proliferation and activation of a variety of haematopoietic and stromal cells. In physiologic conditions, effective responses to injuries are organized, inflammatory triggers are eliminated, inflammation quickly abates, and the normal tissue architecture is restored. However, if inflammatory triggers are not cleared, fibrosis or scarring occur and impaire...

Induction of experimental autoimmune orchitis in mice: responses to elevated circulating levels of the activin-binding protein, follistatin
Experimental autoimmune orchitis (EAO) is a rodent model of chronic testicular inflammation that mimics the pathology observed in some types of human infertility. In a previous study, testicular expression of the inflammatory/immunoregulatory cytokine, activin A, was elevated in adult mice during the onset of EAO, indicating a potential role in the regulation of the disease. Consequently, we examined the development of EAO in mice with elevated levels of follistatin, an endogenous activin antagonist, as a potential therapeutic approach to testicular inflammation. Prior to EAO induction, mice received a single intramuscular...

The role of sleep in pemphigus: a review of mechanisms and perspectives
AbstractPemphigus is an autoimmune bullous disease that causes the development of blisters and erosions on the skin and/or mucosa. Its inflammatory process is mediated by cytokines, which interact with sleep in a bidirectional manner. Pain, a frequent symptom due to pemphigus lesions, is well known to impair sleep quality. Depression is also associated with pemphigus and pro-inflammatory cytokines and may impair sleep. Additionally, a common relationship among other dermatological diseases and sleep has increasingly been described. Poor sleep quality is associated with an increased risk for autoimmune diseases, and insomni...

[Research Articles] The microvascular niche instructs T cells in large vessel vasculitis via the VEGF-Jagged1-Notch pathway
We report that adventitial microvascular endothelial cells (mvECs) perform immunoregulatory functions by up-regulating the expression of the Notch ligand Jagged1. Vascular endothelial growth factor (VEGF), abundantly present in GCA patients’ blood, induced Jagged1 expression, allowing mvECs to regulate effector T cell induction via the Notch–mTORC1 (mammalian target of rapamycin complex 1) pathway.

MiR-30a Positively Regulates the Inflammatory Response of Microglia in Experimental Autoimmune Encephalomyelitis
AbstractMultiple sclerosis (MS) is a classical inflammatory demyelinating disease of the central nervous system (CNS). Microglia are the main resident immune cells in the CNS and are closely associated with the pathogenesis of MS. In the present study, we found that miR-30a was highly expressed in jellyfish-like microglia in chronic active lesions of MS patients, as well as in the microglia of mice with experimental autoimmune encephalomyelitis (EAE) at the chronic phase.In vitro, the conditioned supernatant of mouse microglia overexpressing miR-30a promoted the apoptosis of oligodendrocyte precursor cells (OPCs), and inhi...

Alopecia Areata: a Comprehensive Review of Pathogenesis and Management
AbstractAlopecia areata is a common hair loss condition that is characterized by acute onset of non-scarring hair loss in usually sharply defined areas ranging from small patches to extensive or less frequently diffuse involvement. Depending on its acuity and extent, hair loss is an important cause of anxiety and disability. The current understanding is that the condition represents an organ-specific autoimmune disease of the hair follicle with a genetic background. Genome-wide association studies provide evidence for the involvement of both innate and acquired immunity in the pathogenesis, and mechanistic studies in mouse...
