The association between excessive training sessions (i.e., overtraining/OT) and periods of inadequate recovery is linked to the nonfunctional overreaching (NFOR) state, which is defined as an unexplained decrement or stagnation of performance. The cytokine hypothesis of OT considers that pro-inflammatory cytokines are responsible by the NFOR state-induced performance decrement. Investigations using rodent models of OT verified increased levels of pro-inflammatory cytokines in hypothalamus, liver, serum and skeletal muscle samples...

In CKD patients, arteriosclerotic lesions, including calcification, can occur in vascular smooth muscle cells in a process called Moenckeberg's medial arteriosclerosis. Iron overload induces several complications, including the acceleration of arteriosclerosis. However, the relationship between Moenckeberg's arteriosclerosis in vascular smooth muscle cells and iron accumulation has remained unknown. We tested the accelerated effect of iron on calcification in cultured human aortic vascular smooth muscle cells (HASMCs)...

SLC26A3 encodes a Cl-/HCO3- ion transporter that is also known as downregulated in adenoma (DRA) and is involved in HCO3-/mucus formation. The role of DRA in the epithelial barrier has not been previously established. In this study, we investigated the in vivo and in vitro mechanisms of DRA in the colon epithelial barrier. Immunofluorescence (IF) and co-immunoprecipitation (co-IP) studies reveal that DRA binds directly to tight junction (TJ) proteins and affects the expression of TJ proteins in polarized Caco-2BBe cells...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a non-specific inflammation, which involves the airways, lung parenchyma and pulmonary vessels. The inflammation causes the activation of inflammatory cells and the release of various inflammatory mediators such as interleukin-1 beta, interleukin-6 and tumor necrosis factor alpha (TNF-a). The present study was designed to assess the serum cytokines [Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Tumor necrosis factor-α (TNF-α)] levels in chronic obstructive pulmonary disease (COPD) patients and they were correlated with severity of disease by spirometric measurements...

BACKGROUND: No specific (only subgroup) recommendations for the use of long-acting muscarinic antagonists in chronic obstructive pulmonary disease (COPD) exist. The aim of this exploratory hypothesis generating study was to assess whether different phenotypic/endotypic characteristics could be determinants of the short-term ineffectiveness of the initial tiotropium bromide monotherapy in treatment naïve moderate to severe COPD patients. METHODS: A total of 51 consecutively recruited COPD patients were followed for 3 months after the initial evaluation and prescribed initial treatment (tiotropium)...

Clinical and laboratory results document psoriatic arthritis in a 56-year old patient. The symptoms did not resolve with standard treatments (nonsteroidal anti-inflammatory drugs, steroids and methotrexate). TNF-alpha inhibitors (certolizumab pegol and adalimumab) were added to the treatment regime, with some adverse effects. A trial of human umbilical cord stem cell therapy was then initiated. The stem cells were enriched and concentrated from whole cord blood, by removal of erythrocytes and centrifugation...

Theta-defensins (θ-defensins) are macrocyclic peptides expressed exclusively in granulocytes and selected epithelia of Old World monkeys.  They contribute to anti-pathogen host defense responses by directly killing a diverse range of microbes.  Of note, θ-defensins also modulate microbe-induced inflammation by affecting the production of soluble tumor necrosis factor (sTNF) and other proinflammatory cytokines.  Here, we report that natural rhesus macaque θ-defensin (RTD) isoforms regulate sTNF cellular release by inhibiting TNF alpha converting enzyme (TACE; also known as a disintegrin and metalloprotease 17; ADAM17), the primary pro-TNF sheddase...

Background/aim: Juvenile idiopathic arthritis (JIA) is a chronic complex autoimmune disease. Genetic and environmental factors increase the risk of JIA. It is accepted that alterations in immune system pathways play an important role in the pathogenesis of JIA. The aim of the study was to investigate the possible association between immune system regulatory gene polymorphisms and JIA in Turkish patients. Materials and methods: We analyzed eight polymorphisms, TNF-alpha-863 C > A, TNFRII 196 T > G, IL2-631 G > A, IL13-1112 C > T, CCR2 190 G > A, CCR5delta32, CTLA4-1661 A > G, and PTPN22 1858 C > T, in 76 patients with JIA and in 80 healthy controls, who were of a similar age and same sex...

Monitoring the immune status of cetaceans is important for a variety of health conditions. Assays to quantify cytokines, especially pro-inflammatory cytokines, could be employed, in addition to currently available diagnostic assays, to screen for alterations in the health status of an animal. Though a number of immunological assays are readily available for humans and mice, specific assays for many veterinary species, including cetaceans such as bottlenose dolphins (Tursiops truncatus), are more limited. Herein, we describe the development of IFN-gamma (IFN-γ) and TNF-alpha (TNF-α) enzyme-linked immunosorbent assays (ELISAs) specific to bottlenose dolphins...

Gestational diabetes mellitus (GDM) is a metabolic and low-grade inflammatory disease most commonly found in pregnant women with high body mass index and non-Caucasian ethnicities; however, not all women of high-risk groups develop GDM. We hypothesized that regulatory T cells (Tregs) might present a role in suppressing GDM development. To this end, 55 high-risk women at early pregnancy (first trimester) were recruited, and 21 of them developed GDM while the other 34 did not. Compared to those subjects who did not develop GDM (non-GDM), the patients who developed GDM presented reduced levels of Tregs and elevated levels of serum interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha)...
