We present the first case of simultaneous development of Graves ’ disease and type 1 diabetes during anti‐programmed cell death 1 therapy. Among Japanese participants with autoimmune polyglandular syndrome type III, the frequency of human leukocyte antigen‐DRB1*04:05 is higher in those with both type 1 diabetes and Graves’ disease. The present partic ipant carried the human leukocyte antigen‐DRB1*04:05; which might be associated with the simultaneous development of the two diseases. AbstractWe present the first case of simultaneous development of Graves ’ disease and type 1 ...

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) that is associated with demyelination and neuronal loss. Over recent years, the immunological and neuronal effects of tryptophan (Trp) metabolites have been largely investigated, leading to the hypothesis that these compounds and the related enzymes are possibly involved in the pathophysiology of MS. Specifically, the kynurenine pathway of Trp metabolism is responsible for the synthesis of intermediate products with potential immunological and neuronal effects. More recently, Trp metabolites, originating also from the host microbiome, have...

In this study, we first aim to determine whether SiO2 might alter efferocytosis capacities of human and mouse macrophages. We secondly explore possible mechanisms explaining efferocytosis impairment, with a specific focus on macrophage polarization and on the RhoA/ROCK pathway, a key regulator of cytoskeleton remodeling and phagocytosis. Human monocyte-derived macrophages (MDM) and C57BL/6J mice exposed to SiO2 and to CFSE-positive apoptotic Jurkat cells were analyzed by flow cytometry to determine their efferocytosis index (EI). The effects of ROCK inhibitors (Y27632 and Fasudil) on EI of SiO2-exposed MDM and MDM from SSc...

N-linked glycans play an important role in immunity. Although the role of N-linked glycans in the Fragment crystallizable (Fc) region of immunoglobulins has been thoroughly described, the function of N-linked glycans present in Ig-variable domains is only just being appreciated. Most of the N-linked glycans harbored by immunoglobulin variable domain are of the complex biantennary type and are found as a result of the presence of N-linked glycosylation that most often have been introduced by somatic hypermutation. Furthermore, these glycans are ubiquitously present on autoantibodies observed in some autoimmune diseases as w...

by Robin A. Welsh, Nianbin Song, Catherine A. Foss, Tatiana Boronina, Robert N. Cole, Scheherazade Sadegh-Nasseri DO (HLA-DO, in human; murine H2-O) is a highly conserved nonclassical major histocompatibility complex class II (MHC II) accessory molecule mainly expressed in the thymic medulla and B cells. Previous reports have suggested possible links between DO and autoimmunity, Hepatitis C (HCV) infection, a nd cancer, but the mechanism of how DO contributes to these diseases remains unclear. Here, using a combination of various in vivo approaches, including peptide elution, mixed lymphocyte reaction, T-cell receptor (TC...

The idiopathic inflammatory myopathies (IIMs) are a group of systemic autoimmune diseases characterised primarily by muscle inflammation but also potentially accompanied by a range of extra-muscular manifestations. Dermatomyositis (DM), polymyositis (PM) and inclusion body myositis (IBM) constitute well-characterised subtypes of IIM, with the entity of non-specific idiopathic inflammatory myopathy (NSIIM) being more recently described [1]. Whilst these IIM subtypes are distinguished on clinical, serological and histological grounds, they are unified by the presence of a typically prominent intramuscular lymphocytic infiltrate.

This is the latest in a series of yearly posts in which I suggest areas of development for biotech startups I'd like to see actively developed as a part of the longevity industry in the near future. Today, this year, is a good time to be starting a company focused on the production of a novel therapeutic approach to intervening in the aging process. There is a great deal of funding for seed stage investment, and many compelling projects lacking champions, yet to be carried forward from academia into preclinical development. Numerous scientific and industry crossover conferences are now held every year, at which it is possi...

Discussion Myasthenia gravis (MG) is a problem of the neuromuscular junction which causes muscle weakness. It can occur in all ages and have a range of symptoms from mild localized disease to mortality-threatening respiratory failure. MG occurs in 1.7-30 cases/million, with a prevalence of 77.7 cases/million. Pediatric patients comprise 10-15% of all patients with MG. In various Asian populations, the juvenile MG can be up to 50% of all of the MG cases. Fluctuations in muscle weakness is a hallmark of the disease. As a reminder, “[i]n normal synaptic transmission in the neuromuscular junction, the axon is depolarize...

Authors: Chelvanambi M, Weinstein AM, Storkus WJ Abstract The ability of the immune system to prevent or control the growth of tumor cells is critically dependent on inflammatory processes that lead to the activation, expansion, and recruitment of antitumor effector cells into the tumor microenvironment (TME). These processes are orchestrated by soluble cytokines produced in tissues that alarm local immune surveillance cells (such as dendritic cells, DCs) to mobilize protective antitumor immune populations (B cells, T cells). The interleukin (IL)-36 family of pro-inflammatory cytokines plays an important role ...

AbstractThis guideline aims to describe the complement system and the functions of the constituent pathways, with  particular focus on primary immunodeficiencies (PIDs) and their diagnosis and management. The complement system is a crucial part of the innate immune system, with multiple membrane-bound and soluble components. There are three distinct enzymatic cascade pathways within the complement system, the classical, alternative and lectin pathways, which converge with the cleavage of central C3. Complement deficiencies account for ~5% of PIDs. The clinical consequences of inherited defects in the complement system...
