Recurrent bacterial infections in cases of bisphosphonate-related osteonecrosis of jaw (BRONJ) frequently occur. Therefore, BRONJ are usually treated by radical saucerization followed by intensive antibiotic medications without bisphosphonate therapy. The postoperative exudate (POE) from BRONJ lesions may directly indicate the inflammatory status of osteomyelitis in patients, but so far, the POE has rarely been examined for its expression of various cytokines and wound healing proteins. A total of 27 cases of BRONJ, which involved the mandible, were selected and their individual POE collected 6 h, 1 day, and 2 days after surgical intervention was analyzed by immunoprecipitation high performance liquid chromatography (IP-HPLC)...

OBJECTIVE: Periapical periodontitis results in alveolar bone resorption around the root apex. During the progression of inflammation, host cells release various inflammatory mediators and pro-inflammatory cytokines through immune responses. However, the pathological mechanisms associated with periapical bone destruction remain unclear. This study was objected to identify differentially regulated proteins in periapical periodontitis via a quantitative proteomics approach using isobaric tags for relative and absolute quantification (iTRAQ) labelling of peptides...

This study examined the impact of corticotropin-releasing hormone type 1 receptor (CRHR1) blockade using Antalarmin (ANT) on the expression of markers of neuroplasticity and inflammation, as well as neuroprotection and behavioral recovery following global cerebral ischemia. Male Wistar rats (N=50) were treated with ANT (2μg/2μl; icv) or a vehicle solution prior to a sham or four vessel (4VO) occlusion. Seven days post ischemia, anxiety was assessed in the Elevated Plus Maze and Open Field tests, and fear and spatial learning in a Y-Maze Passive Avoidance Task and the Barnes Maze...

BACKGROUND: Th1, Th2, Th17, Treg and Tfh cells play important roles in schistosomiasis. Th9 cells secrete IL-9 as a signature cytokine and contribute to several classes of inflammatory disease. However, the effects of Th9 cells in schistosomiasis are unknown. We aimed to explore the dynamic changes and potential roles of Th9 cells in the pathogenesis of hepatic egg granulomatous inflammation in mice infected with Schistosoma japonicum. METHODS: Twenty mice with S...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common, chronic liver disease worldwide. Recent studies have shown that T helper (Th) 17 and regulatory T (Treg) cells play critical roles in various disorders of liver inflammation. Here, we explored the value of polyene phosphatidylcholine capsules (PPC) for regulating the imbalance of Th17/Treg cells in the pathogenesis of mice with NAFLD. METHODS: C57BL/6 mice were randomly divided into three groups as follows:normal diet (ND), high-fat diet (HF),and HF plus PPC(HF + PPC)...

Alcoholic liver disease (ALD) is one of the predominant causes of liver-related morbidity and mortality worldwide. However, effective therapy for ALD is still lacking. Wogonin, a major flavonoid compound, is found in Scutellaria baicalensis Georgi. Accumulating studies have revealed that wogonin possesses anti-inflammatory and anti-tumour activities in various models. However, the hepatoprotective activity of wogonin in ALD is still obscure. In this study, we found that wogonin significantly attenuated inflammatory response in EtOH-fed mice, and reduced the expression of inflammatory cytokines such as TNF-α and IL-6 in EtOH-induced RAW264...

Three series of H2S donors based on NSAIDs were synthesized and characterized by (1)H-NMR, IR and ESI-HRMS. The H2S-release abilities of all compounds were evaluated in the presence of TECP or cysteine. The results show all compounds were fast H2S-releasers, and their half-lives were in range of 0-20 min. Under the same condition, H2S released from compound 9 was more than any other compounds. In cytotoxicity aspect, all compounds but 1 and 2 displayed much lower toxicities to both LO2 and HepG2 cell lines, and the IC50 values of most compounds were over 800 μM...

BACKGROUND: Extremely preterm infants born at the border of viability (22-24 weeks' gestation) have high rates of death and lasting disability. Ex vivo uterine environment therapy is an experimental neonatal intensive care strategy that provides gas exchange using parallel membranous oxygenators connected to the umbilical vessels, sparing the extremely preterm cardiopulmonary system from ventilation-derived injury. OBJECTIVE: In this study, we aimed to refine our ex vivo uterine environment therapy platform to eliminate fetal infection and inflammation, while simultaneously extending the duration of hemodynamically stable ex vivo uterine environment therapy to 1 week...

BACKGROUND AND AIMS: Patients with severe exacerbation of chronic hepatitis B (SE-CHB) are at risk of developing acute-on-chronic liver failure (ACLF). Systemic inflammation (SI) is a major driver of ACLF. The aim of this study was to identify characteristics of SI in hepatitis B-precipitated-ACLF (HB-ACLF), which may be distinct from No-ACLF patients with SE-CHB. METHODS: Two cohorts of patients with SE-CHB were enrolled in two tertiary hospitals. The associations between circulating leukocyte counts/subsets and ACLF progression and prognoses were analysed in Cohort A...

Multiple sclerosis (MS) is an autoimmune disease where myelin is incorrectly recognized as foreign and attacked by the adaptive immune system. Dendritic cells (DCs) direct adaptive immunity by presenting antigens to T cells, therefore serving as a target for autoimmune therapies. N-Phenyl-7-(hydroxyimino)cyclopropa[b]chromen-1a-carboxamide (PHCCC), a positive allosteric modulator of metabotropic glutamate receptor 4 (mGluR4), can promote regulatory T cells by altering cytokine secretion to bias T cell differentiation...

MicroRNAs are small endogenous noncoding RNAs implicating in the regulation of diverse biological processes, including proliferation, differentiation, cancer, apoptosis, and viral infections. MicroRNAs regulate gene expression by either mRNA degradation or inhibition of protein translation. Although microRNAs have emerged as important controller involved in regulation of inflammatory response, the microRNA-mediated regulatory mechanism remains less clear in teleost. Here, we report that miR-148 targets MyD88 and down-regulates its expression by inhibition protein translation rather than degradation mRNA in miiuy croaker...

Type 1 diabetes (T1D) manifests when the insulin-producing pancreatic β cells are destroyed as a consequence of an inflammatory process initiated by lymphocytes of the immune system. The NOD mouse develops T1D spontaneously and serves as an animal model for human T1D. The IL-4Rα/IL-13Rα1 heteroreceptor (HR) serves both IL-4 and IL-13 cytokines, which are believed to function as anti-inflammatory cytokines in T1D. However, whether the HR provides a responsive element to environmental (i.e., physiologic) IL-4/IL-13 in the regulation of peripheral tolerance and the development of T1D has yet to be defined...

BACKGROUND: Cardiopulmonary bypass (CPB) may induce systemic inflammatory responses causing acute lung injury. Recombinant human soluble thrombomodulin (rTM) is reported to attenuate the secretion of inflammatory cytokines and the high-mobility group box 1 (HMGB1) protein, which is critical in controlling systemic inflammation and apoptosis. We investigated the protective effects of rTM on CPB-induced lung injury in a rat model. METHODS: Eighteen male Sprague-Dawley rats were divided into 3 groups: sham, control (CPB alone), and rTM (CPB + rTM)...

Given the importance of leukotrienes in vascular inflammation induced by local tissue injury, this study investigated the role for 5-lipoxygenase (5-LO) in monocytes in the development of intimal hyperplasia. As a mechanistic study, the importance of monocyte 5-LO in monocyte-macrophage differentiation with subsequent infiltration in neointima was evaluated. In a mouse model of wire-injured femoral artery, intimal hyperplasia started as early as 2 wks after injury, and luminal area and blood flow were reduced due to increased neointima formation...

Inflammation has been recently acknowledged as a key participant in the physiopathology of oncogenesis and tumor progression. The inflammatory cytokine IL-1β has been reported to induce the expression of markers associated with malignancy in breast cancerous cells through Epithelial-Mesenchymal Transition (EMT). Aggressive breast cancer tumors classified as Triple Negative do not respond to hormonal treatment because they lack three crucial receptors, one of which is the estrogen receptor alpha (ERα). Expression of ERα is then considered a good prognostic marker for tamoxifen treatment of this type of cancer, as the binding of this drug to the receptor blocks the transcriptional activity of the latter...

BACKGROUND: Dendritic cells (DCs) are specialized first-line sensors of foreign materials invading the organism. These sentinel cells rely on pattern recognition receptors such as Nod-like or Toll-like receptors (TLRs) to launch immune reactions against pathogens, but also to mediate tolerance to self-antigens and, in the intestinal milieu, to nutrients and commensals. Since inappropriate DC activation contributes to inflammatory diseases and immunopathologies, a key question in the evaluation of orally ingested nanomaterials is whether their contact with DCs in the intestinal mucosa disrupts this delicate homeostatic balance between pathogen defense and tolerance...
