Abstract Background Rheumatoid Arthritis (RA) is a chronic inflammatory disease, affecting women more than men, with a more aggressive course in women. Design A prospective study that recruited 58 patients (46 women aged 56 ± 12 years) with active long-standing RA disease (>12 months). Our goals were to measure their endothelial function, part of the…

Abstract Background Targeting epitopes derived from neo-antigens (or “neo-epitopes”) represents a promising immunotherapy approach with limited off-target effects. However, most peptides predicted using MHC binding prediction algorithms do not induce a CD8 + T cell response, and there is a crucial need to refine the predictions to readily identify the best antigens that could mediate T-cell responses. Such…

Abstract Cancer is the second leading cause of death globally. Matching proper treatment and dosage is crucial for a positive outcome. Any given drug may affect patients with similar tumors differently. Personalized medicine aims to address this issue. Unfortunately, most cancer samples cannot be expanded in culture, limiting conventional cell‐based testing. Herein, presented is a…

ABSTRACT Stressful life events are considered a risk factor for autoimmune disorders, though the mechanisms are unclear. Here we demonstrate that chronic social stress induces virulence-associated transcriptional patterns in the murine gut microbiota. The stress-influenced microbiota increased the presence of effector T helper cells in the mesenteric lymph nodes, including myelin-autoreactive cells. Inhibition of the…

Abstract The most common stress reactions following combat are post-traumatic stress reactions. These responses have a great impact on quality-of-life and can damage victims’ personal, familial, and social functioning. However, of the people who develop PTSD, only a few request psychological help. The first aim of the research was, therefore, to examine the long-term adjustment…

AbstractGrowing evidence highlights the role of arginase activity in the manifestation of Alzheimer’s disease (AD). Upregulation of arginase was shown to contribute to neurodegeneration. Regulation of arginase activity appears to be a promising approach for interfering with the pathogenesis of AD. Therefore, the enzyme represents a novel therapeutic target. In this study, we administered an…
