The failure of preclinical testing to predict the severity of the cytokine storm experienced by the recipients of the superagonistic anti-CD28 monoclonal antibody (mAb) TGN1412 during its Phase 1 clinical trial prompted the development of new in vitro experimental approaches for mimicking in vivo cytokine release and lymphoproliferation. Peripheral blood mononuclear cells (PBMC) presented to TGN1412...
Plasma levels of YKL-40 are elevated in patients with systemic infection, inflammatory disorders and cancer. Both monocytes/macrophages, neutrophils, and cancer cells have the capacity to produce YKL-40, but the regulation during the inflammatory response is unknown. To study the possible role of interleukin-6 (IL-6) and tumor necrosis factor (TNF)-α in the regulation of YKL-40 plasma levels, we included...
Proinflammatory cytokines produced by immune cells destroy pancreatic beta cells in type 1 diabetes. The aim of this study was to investigate the cytokine network and its effects in insulin-secreting cells. INS1E cells were exposed to different combinations of proinflammatory cytokines. Cytokine toxicity was estimated by MTT assay and caspase activation measurements. The NFκB-iNOS pathway was analyzed...
Many observational epidemiologic studies suggest an association between exercise and breast cancer risk. However, the lack of controlled experimental studies that examine this relationship and the mechanisms involved weaken the basis for inferring a causal relationship. Inflammation plays a role in breast cancer progression and exercise has been reported to reduce inflammation; however, the anti-inflammatory...
The effects of LDL-apheresis (LDLa) with dextran sulphate on plasma cytokines in 6 homozygous familial hypercholesterolemic (HozFH) patients, were evaluated.Plasma IL-1α; IL-1ra; IL-4; IL-6; IL-10; IL-12(p40); IL-12(p70); TNF-α, sTNF-R, VEGF, VEGF-R1, E-Selectin (ESEL), and P-Selectin (PSEL) concentrations were measured before and after LDLa on three consecutive sessions for each patient.TNF-α was...
Skeletal muscle contractile activity increases the production of the myokines interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-15 (IL-15) and also skeletal muscle glucose transport. Previous work has revealed a role for IL-6 in mediating glucose uptake, while research on the physiological roles of IL-8 and IL-15 is not so abundant. In the present study we investigated the effects of different...
Localized scleroderma (LS) is a disfiguring autoimmune disease of the skin and underlying tissue that mainly affects the pediatric population. Inflammation of the tissue leads to fibrosis and atrophy, causing physical and psychological disability that can continue throughout childhood into adulthood. Available therapies for LS have had variable effects and are associated with morbidity themselves...
Burn is associated with profound inflammation and activation of the innate immune system in multiple organ beds, including the lung. Similarly, toll-like receptors (TLR) are associated with innate immune activation. Nonetheless, it is unclear what impact burn has on TLR-induced inflammatory responses in the lung.Male C57BL/6 mice were subjected to burn (3rd degree, 25% TBSA) or sham procedure and...
The inflammatory response, and its subsequent resolution, are the result of a very complex cascade of events originating at the site of injury or infection. When the response is severe and persistent, Systemic Inflammatory Response Syndrome can set in, which is associated with a severely debilitating systemic hypercatabolic state. This complex behavior, mediated by cytokines and chemokines, needs...
