Probiotic complex, zinc, and coenzyme Q10 (CoQ10) are recognized dietary supplements with an anti-inflammatory role. Although these supplementations are individually known to benefit rheumatoid arthritis (RA), there is no evidence suggesting any synergic effect. The primary goal of this study is to determine whether probiotic complex, zinc, and CoQ10 attenuate the development of collagen-induced arthritis (CIA). The combination of probiotic complex, zinc, and CoQ10 reduced CIA severity by downregulating the levels of IgG, IgG1, and IgG2a in serum...

Systemic juvenile idiopathic arthritis (SJIA) is a severe childhood arthropathy with features of autoinflammation. Monocytes and macrophages in SJIA have a complex phenotype with both pro- and anti-inflammatory properties that combine features of several well characterized in vitro conditions used to activate macrophages. An important anti-inflammatory phenotype is expression of CD163, a scavenger receptor that sequesters toxic pro-inflammatory complexes that is highly expressed in both active SJIA and macrophage activation syndrome (MAS)...

Psoriasis is a systemic inflammatory disease associated with numerous comorbidities and a profound impact on patients' quality of life. While its complex immune pathogenesis is still not fully delineated, current evidence supports a fundamental role of the T-helper-17 (TH-17) pathway and its related interleukin-17 (IL-17) cytokine. Thus, new antipsoriatic therapies have been developed to block this key cytokine and its downstream effects. Secukinumab is a fully humanized, monoclonal anti-IL-17A antibody, and the first in its class to be approved by the US Food and Drug Administration for the treatment of moderate to severe plaque psoriasis...

BACKGROUND: Immune-mediated inflammatory diseases (IMID), such as inflammatory bowel disease (IBD), multiple sclerosis (MS), and rheumatoid arthritis (RA), are highly prevalent in Canada and the United States and result in substantial personal and societal burden. The prevalence of psychiatric comorbidities, primarily depression and anxiety, in IMID exceeds those in the general population by two- to threefold, but remains underdiagnosed and undertreated. Furthermore, the effects of psychiatric comorbidity on IMID are not well understood...

Rheumatoid arthritis (RA), a chronic and joint-related autoimmune disease, results in immune dysfunction and destruction of joints and cartilages. Small molecules and biological therapies have been applied in a wide variety of inflammatory disorders, but their utility as a therapeutic agent is limited by poor absorption, rapid metabolism, and serious side effects. To improve these limitations, nanoparticles, which are capable of encapsulating and protecting drugs from degradation before they reach the target site in vivo, may serve as drug delivery systems...

OBJECTIVES: Regulatory T cells (Tregs) modulate immune responses and can suppress the development of autoimmune diseases. Tumor necrosis factor receptor 2 (TNFR2) has been recognized as a key receptor on these cells that facilitates expansion and stabilization of CD4+ Tregs. Here, we investigated the therapeutic activity of a novel TNFR2 agonist in experimental arthritis and the role of different Treg subsets. METHODS: A novel mouse TNFR2-selective fusion protein (EHD2-sc-mTNFR2 ) was generated by genetic engineering...

Inflammatory bone diseases, including rheumatoid arthritis, periodontitis and peri-implantitis, are associated not only with the production of inflammatory cytokines but also with local oxidative status, which is defined by intracellular reactive oxygen species (ROS). Osteoclast differentiation has been reported to be related to increased intracellular ROS levels in osteoclast lineage cells. Sudachitin, which is a polymethoxyflavone derived from Citrus sudachi, possesses antioxidant properties and regulates various functions in mammalian cells...

BACKGROUND: The use of immune checkpoint inhibitors (ICI) has grown incessantly since they were first approved in 2014. These monoclonal antibodies inhibit T cell activation, yielding a dramatic tumor response with improved survival. However, immunotherapy is frequently hampered by immune adverse events (iAE) such as hypophysitis, colitis, hepatitis, pneumonitis and rash. Until recently, rheumatic side effects were only infrequently reported. Aim To describe the rheumatic manifestations encountered among patients treated with ICIs in a large tertiary cancer center in Israel METHODS: The cancer center's patient registry was screened for patients who had ever been treated with ipilimumab, pembrolizumab and/or nivolumab with relevant data gathered from clinical charts...

Rheumatoid arthritis (RA) and periodontal disease (PD) are chronic inflammatory diseases that share similar osteoclasia, human leukocyte antigen-DR4 allelic genes and immunological profile, and characteristic cytokines. Smoking can contribute to more severe RA and PD; secretion of pro-inflammatory mediators destroys the soft synovial membrane and periodontium, respectively. Anti-citrullinated protein antibodies and anti-α-enolase antibody are characteristic of these two diseases. Some studies suggest that PD may be associated with RA...

Gut microorganisms (microbiota) live in symbiosis with the host and influence human nutrition, metabolism, physiology, and immune development and function. The microbiota prevents pathogen infection to the host, and in turn the host provides a niche for survival. The alteration of gut bacteria composition (dysbiosis) could contribute to the development of immune-mediated diseases by influencing the immune system activation and driving the pro- and anti-inflammatory responses in order to promote or counteract immune reactions...

Staphylococcal septic arthritis remains a serious medical concern due to rapid and sustained production of inflammatory cytokines that leads to progressive and irreversible joint destruction with high mortality rate in patients despite adequate antibiotics treatment. TNF-α signalling via TNFR-1 contributes to arthritic destruction by aggravating inflammation. Impact of TNFR-2 signalling is not well established in this aspect. Hence the objective of our study was to evaluate the role of dual neutralization TNFR-1 and TNFR-2 in the pathogenesis of S...

There is burgeoning interest in the interaction between the immune and nervous systems. Pain is mediated by primary sensory neurons (nociceptors) that can respond to a variety of thermal, mechanical and chemical signals. Cytokines are now recognized as important mediators of inflammatory pain. They can induce nociceptor sensitization indirectly via mediators, wherein neurons become primed and thus become more responsive to stimulation; alternatively, there is also evidence that cytokines can directly activate neurons via their specific receptors present on the neuronal cells...
