Background/aim: Exercise benefits the cardiovascular system, but strenuous exercise can cause cardiac damage and induce cytokine production, particularly that of interleukin-6 (IL-6). Hepcidin, which is primarily regulated by IL-6, increases after exercise. Hepcidin is a possible protective factor against the adverse effects of strenuous exercise such as oxidative stress. The aim of the study is to reveal that training increases hepcidin and attenuates increased levels of IL-6 in the hearts of exhaustively exercised rats by comparing the IL-6 and hepcidin mRNA expression levels in trained and untrained groups...

BACKGROUND: Poor viability and retention of transplanted bone marrow mesenchymal stem cells (BM-MSC) remains an obstacle in promoting healing after myocardial infarction (MI). This study aimed to understand the migratory, angiogenic, and cardioprotective effects induced by tumor necrosis factor (TNF)-α and hypoxia through rat BM-MSC (rBM-MSC) paracrine secretions, collectively referred to as secretome, after MI. METHODS: Secretome from rBM-MSC cultures treated with various combinations of H9c2 cardiomyoblast-conditioned medium, TNF-α, and hypoxia was initially collected...

Peritoneal macrophages (PMs) are the major cell type of peritoneal cells, which participate in multiple aspects of innate and acquired immunity in peritoneal cavity. PMs have an ability to release a large amount of pro-inflammatory and antiinflammatory cytokines, and therefore play a critical role in regulating the differentiation of innate immune cells and inflammatory T cells. Accumulating studies demonstrate that the immunological reactions and inflammatory responses of PMs are strongly related to the pathogenic processes of various inflammatory diseases and abdominal cancers...

BACKGROUND: Laparoscopy is becoming more common in neonates. However, concerns remain about the impact of the carbon-dioxide (CO2)-insufflation over the neonatal brain. We aim to evaluate the peripheral (serum) and central (cerebrospinal fluid [CSF]) cytokine response after neonatal CO2-pneumoperitoneum and its impact over neurodevelopmental milestones acquisition and long-term behavioral outcomes. MATERIALS AND METHODS: Rats were subjected to a systematic assessment of neurodevelopmental milestones between postnatal day 1 (PND 1) and PND 21...

Cudratricusxanthone A (CTXA), a natural bioactive compound extracted from the roots of Cudraniatricuspidata Bureau, is known to possess antithrombotic, antiproliferative and antiinflammatory activities. It remains unclear that CTXA can improve hepatoprotective activity in vivo. The objective of this study was to investigate the effect of CTXA on lipopolysaccharide (LPS)-induced liver failure in mice, and to elucidate its underlying molecular mechanisms. Liver failure was induced by LPS (15 mg/kg, i.p.) in mice, and 12 h later, they were treated intravenously with CTXA...

Aberrant inflammation as a result of activation of the transmembrane protein Toll-like receptor 4 belonging to pattern recognition receptor and subsequent phosphorylation of signaling proteins facilitated by reactive oxygen species has been linked to a myriad of diseases. Sorghum is a drought-resistant cereal with health promoting properties associated with its biologically active substances such as kafirin. Kafirin is an alcoholsoluble protein and accounts for as much as 70% of the total proteins in sorghum...

INTRODUCTION: Today, not only the existence of an interrelation between obesity/adipositas and osteoarthritis (OA) but also the association of OA and diabetes mellitus (DM) are widely recognized. Nevertheless, shared influence factors facilitating OA development in DM patients still remain speculative up until now. To supplement the analysis of clinical data, appropriate in vitro models could help to identify shared pathogenetic pathways. Informative in vitro studies could later be complemented by in vivo data obtained from suitable animal models...

Cancer therapy reduces tumor burden by killing tumor cells, yet it simultaneously creates tumor cell debris that may stimulate inflammation and tumor growth. Thus, conventional cancer therapy is inherently a double-edged sword. In this study, we show that tumor cells killed by chemotherapy or targeted therapy ("tumor cell debris") stimulate primary tumor growth when coinjected with a subthreshold (nontumorigenic) inoculum of tumor cells by triggering macrophage proinflammatory cytokine release after phosphatidylserine exposure...

Microglia (MG), a heterogeneous population of phagocytic cells, play important roles in central nervous system (CNS) homeostasis and neural plasticity. Under steady-state conditions, MG maintain homeostasis by producing antiinflammatory cytokines and neurotrophic factors, support myelin production, and remove synapses and cellular debris, as well as participating in "cross-correction," a process that supplies neurons with key factors for executing autophagy-lysosomal function. As sentinels for the immune system, MG also detect "danger" signals (pathogenic or traumatic insult), become activated, produce proinflammatory cytokines, and recruit monocytes and dendritic cells to the site of damage through a breached blood-brain barrier or via brain lymphatics...

There is a real need for new interventions for Alzheimer's disease (AD). Hyperbaric oxygen therapy (HBOT), the medical administration of 100% oxygen at conditions greater than 1 atmosphere absolute, has been used successfully to treat several neurological conditions, but its effects on AD pathology have never been thoroughly examined. Therefore, we exposed old triple-transgenic (3xTg) and non-transgenic mice to HBOT followed by behavioral, histological, and biochemical analyses. HBOT attenuated neuroinflammatory processes by reducing astrogliosis, microgliosis, and the secretion of proinflammatory cytokines (IL-1β and TNFα) and increasing expression of scavenger receptor A, arginase1, and antiinflammatory cytokines (IL-4 and IL-10)...

BACKGROUND: Hydrogen sulfide (H2S) has recently been reported to demonstrate both antiinflammatory and cytoprotective effects; however, its efficacy has not been well documented in large animal models. In this study, we examined whether the administration of H2S offers cytoprotective effects on renal ischemia-reperfusion injury (IRI) in a preclinical miniature swine model. METHODS: Major histocompatibility complex-inbred, CLAWN miniature swine (n = 9) underwent a right nephrectomy, followed by induction of a 120-min period of warm ischemia via placement of clamps on the left renal artery and vein...

In this study, we aim to develop a new, reproducible crush injury (CI) model in rabbits. Anesthetized rabbits were compressed on both hind limbs using a special instrument for 6 h followed by 3 h of reperfusion. Blood samples and injured muscles were collected for biochemical analysis and morphological evaluation. Survival observation lasted for 72 h. Bilateral compressions with 10 kg/kg body weight (BW), but not with 5 kg/kg BW, reduced serious systemic impairment. Bilateral compressions with 10 kg/kg BW resulted in severe lactic acidosis; increased serum K(+), creatine phosphokinase, aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine levels; and a sharply decreased mean arterial blood pressure after compression release...

BACKGROUND AND PURPOSE: A crosstalk between the immune system and depression has been postulated, with a key role played by monocytes/macrophages and cytokines. In this paper we examined whether vortioxetine, a multimodal anti-depressive drug, was endowed of antiinflammatory and anti-oxidative activity, leading to immunomodulatory effects on human monocytes and macrophages. EXPERIMENTAL APPROACHES: Human monocytes were isolated from buffy coats and used as such or differentiated into M1 and M2 macrophages...

BACKGROUND: Blunt thoracic injury often leads to pulmonary contusion and the development of acute respiratory distress syndrome, which carries a high risk of morbidity and mortality, originating from the local and systemic inflammatory states. This study aimed to investigate the local and systemic antiinflammatory effects of levosimendan in rat models of blunt chest trauma. METHODS: A total of 32 Wistar albino rats were randomly assigned to one of the following four groups: control, sham, low-dose levosimendan (LDL) (5 µg/kg loading dose for 10 min and 0...

BACKGROUND: Inflammatory events in brain parenchyma and glial tissue are involved in epileptogenesis. Blood concentration of cytokines is shown to be elevated after tonic-clonic seizures. As a result of inflammation, blood-brain barrier leakage occurs. This can be documented by imaging techniques, such is dynamic susceptibility contrast enhanced (DSC) MRI perfusion. Our aim was to check for postictal brain inflammation by studying DSC MRI perfusion and plasma level of cytokines. We looked for correlations between number and type of introducing seizures, postictal plasma level of cytokines and parameters of DSC MRI perfusion...

In multiple sclerosis, the pathological interaction between autoreactive Th cells and mononuclear phagocytes in the CNS drives initiation and maintenance of chronic neuroinflammation. Here, we found that intrathecal transplantation of neural stem/precursor cells (NPCs) in mice with experimental autoimmune encephalomyelitis (EAE) impairs the accumulation of inflammatory monocyte-derived cells (MCs) in the CNS, leading to improved clinical outcome. Secretion of IL-23, IL-1, and TNF-α, the cytokines required for terminal differentiation of Th cells, decreased in the CNS of NPC-treated mice, consequently inhibiting the induction of GM-CSF-producing pathogenic Th cells...

Mesenchymal stromal cells (MSCs) have been extensively investigated as a potential antiinflammatory treatment in many inflammatory-related diseases; however, it remains unclear whether MSCs could be used to treat acute allergic rhinitis. A rat model of allergic rhinitis was treated with MSCs. The effect of MSCs on the inflammation of allergic rhinitis was evaluated by sneezing, nose rubbing, the pathology of the nasal mucosa, and the expression of interleukin 4, tumour necrosis factor alpha, and immunoglobulin E in the serum of rats...

BACKGROUND: 3,3'-Diindolylmethane (DIM) is a condensation product of indole-3-carbinol, a glucosinolate naturally occurring in Brassica genus vegetables. The antiinflammatory properties of DIM through the inhibition of NF-κB, as well as its ameliorating effects on glucose tolerance and hyperglicemic states, have been described. A subclinical proinflammatory profile resultant from the interaction of adipocytes and macrophages have been reported in obesity, affecting the insulin signaling pathway, contributing to insulin resistance...

BACKGROUND: Inflammation and monocytes are thought to be important to human malaria pathogenesis. However, the relationship of inflammation and various monocyte functions to acute malaria, recovery from acute malaria, and asymptomatic parasitemia in endemic populations is poorly understood. METHODS: We evaluated plasma cytokine levels, monocyte subsets, monocyte functional responses, and monocyte inflammatory transcriptional profiles of 1- to 10-year-old Kenyan children at the time of presentation with acute uncomplicated malaria and at recovery 6 weeks later; these results were compared with analogous data from asymptomatic children and adults in the same community...
