BACKGROUND: TMEM16A, a Ca-activated Cl channel, regulates various physiological functions such as mucin secretion. However, the role of TMEM16A in hypersecretion in asthma is not fully understood. OBJECTIVE: The aim of this study is to evaluate Cl ion transport via TMEM16A and determine the localization of TMEM16A in a guinea pig asthma model. METHODS: Guinea pigs were sensitized with OVA ip. on Day 1 and Day 8. On Day 22, we assessed OVA challenge-induced Cl ion transport in the sensitized tracheas ex vivo in an Ussing chamber, compared with the non-sensitized tracheas...

BACKGROUND AND AIM: Enterohepatic immunologic derangement is associated with nonalcoholic steatohepatitis (NASH). Here, we investigated whether Clostridium butyricum B1 (CB) would be an effective immune-targeted substance to attenuate steatohepatitis in mice. METHODS: Thirty mice were randomized into a control group fed with common forage, a high-fat diet (HFD) group fed a HFD for 16 weeks, and a HFD + CB group treated with CB for the latter 8 weeks. Inflammation- or metabolism-associated genes in the liver or epididymal fat tissue were quantified, intrahepatic and intestinal immune factors were detected...

BACKGROUND CONTEXT: Disc degeneration is associated with the progressive loss of the proteoglycan content of the intervertebral disc (IVD), decreased matrix synthesis, higher concentrations of proteolytic enzymes and increased levels of pro-inflammatory cytokines. In previous studies, we have shown that C-C chemokine ligand (CCL)2, CCL3, and CCL5 are highly expressed by cultured nucleus pulposus (NP) and annulus fibrosus (AF) cells that have been treated by interleukin (IL)-1. The major function for these chemokines is to recruit immune cells into the disc...

Chronic obstructive pulmonary disease (COPD) is caused by the build-up of oxidative stress-induced damages due to cigarette smoking, but how monoamine oxidase (MAO)-B signaling is involved remains unclear. This study aims to establish the involvement of MAO-B signaling pathways in cigarette smoke medium (CSM)-induced oxidative stress and inflammation in human airway epithelial cells (AECs). CSM treatment increased MAO-B activity, ROS levels and IL-8 release in AECs. Pretreatment with MAO-B selective inhibitor selegiline reversed the CSM-induced changes in MAO-B activity, ROS levels and IL-8 release in a dose-dependent manner...

BACKGROUND: Exposure to agents via inhalation is of great concerns both in workplace environment and in the daily contact with particles in the ambient air. Reliable human airway exposure systems will most likely replace animal experiment in future toxicity assessment studies of inhaled agents. METHODS: In this study, we successfully established a combination of an exposure system (XposeALI) with 3D models mimicking both healthy and chronic bronchitis-like mucosa by co-culturing human primary bronchial epithelial cells (PBEC) and fibroblast at air-liquid interface (ALI)...

Lack of safe and effective adjuvants is a major hindrance to the development of efficacious vaccines. Signaling via CD40 pathway leads to enhanced antigen processing and presentation, nitric oxide expression, pro-inflammatory cytokine expression by antigen presenting cells, and stimulation of B-cells to undergo somatic hypermutation, immunoglobulin class switching, and proliferation. Agonistic anti-CD40 antibodies have shown promising adjuvant qualities in human and mouse vaccine studies. An anti-CD40 monoclonal antibody (mAb), designated 2E4E4, was identified and shown to have strong agonistic effects on primary cells from multiple livestock species...

BACKGROUND: Asthma is a chronic inflammatory disease characterized by airways hyper-responsiveness (AHR), reversible airway obstruction, and airway inflammation and remodeling. We previously showed that Syk modulates methacholine-induced airways contractility in naïve mice and in mice with allergic airways inflammation. We hypothesize that Syk plays a role in the pathogenesis of AHR; this was evaluated in a chronic 8-week mouse model of house dust mite (HDM)-induced allergic airways inflammation...

Polymers that can activate the immune system may become useful biomaterials tools, given that the mechanisms underlying their actions are well understood. Herein, we report a novel type of interaction between polymers and immune cells - in studying the influence of the three major types of carrageenan (CGN) polysaccharides on monocyte behaviour in vitro, we found only the λ-type induced monocyte adhesion and this action requires the presence of an adequate amount of serum. Further analyses indicated λ-CGN bound interleukin-8 (IL-8) in the serum and activated the cultured monocytes through an IL-8-dependent pathway...

Dysregulated Toll-like receptor (TLR)-4 activation is involved in acute systemic sepsis, chronic inflammatory diseases, such as atherosclerosis and diabetes, and in viral infections, such as influenza infection. Thus, therapeutic control of the TLR4 signalling pathway is of major interest. Here we tested the activity of the small-molecule synthetic TLR4 antagonist, FP7, in vitro on human monocytes and monocyte-derived dendritic cells (DCs) and in vivo during influenza virus infection of mice. Our results indicate that FP7 antagonized the secretion of proinflammatory cytokines (IL-6, IL-8, and MIP-1β) by monocytes and DCs (IC50 < 1 μM) and prevented DC maturation upon TLR4 activation by ultrapure lipopolysaccharide (LPS)...

Conventional dendritic cells (cDC) are professional antigen-presenting cells that induce immune activation or tolerance. Two functionally specialised populations, termed cDC1 and cDC2, have been described in humans, mice, ruminants and recently in pigs. Pigs are an important biomedical model species and a key source of animal protein; therefore further understanding of their immune system will help underpin the development of disease prevention strategies. To characterise cDC populations in porcine blood, DC were enriched from PBMC by CD14 depletion and CD172a enrichment then stained with lineage mAbs (Lin; CD3, CD8α, CD14 and CD21) and mAbs specific for CD172a, CD1 and CD4...

PURPOSE: Euterpe oleracea Mart. (açaí) seed extract (ASE), through its anti-hypertensive, antioxidant and anti-inflammatory properties, may be useful to treat or prevent human diseases. Several evidences suggest that oxidative stress and inflammation contribute to the pathogenesis of diabetic nephropathy; therefore, we tested the hypothesis that ASE (200 mg/kg(-1)day(-1)) prevents diabetes and hypertension-related oxidative stress and inflammation, attenuating renal injury. METHODS: Male rats with streptozotocin (STZ)-induced diabetes (D), and spontaneously hypertensive rats with STZ-induced diabetes (DH) were treated daily with tap water or ASE (D + ASE and DH + ASE, respectively) for 45 days...

Among the subsets of tumor-infiltrating lymphocytes (TILs), activated cytotoxic T lymphocytes (granzyme B(+)) have an antitumor effect, while regulatory T lymphocytes [forkhead box P3 (Foxp3)(+)] suppress the antitumor immune response. The aim of the present study was to investigate the possible associations between TIL subsets and survival outcomes in patients with left-sided pancreatic ductal adenocarcinoma (PDAC). From January 2000 to December 2008, 30 patients who underwent curative distal pancreatectomy without neoadjuvant chemoradiotherapy due to left-sided PDAC were enrolled in the present study...

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease, in which adiponectin may serve an important role. The present study investigated the role of adiponectin in the apoptotic and damaging effect of cigarette smoke extract (CSE) on human bronchial epithelial cells (16HBECs). An MTT assay showed that CSE significantly inhibited the proliferation of 16HBECs (F=1808.88, P<0.01). The 16HBECs were treated with different concentrations of high molecular weight (HMW) adiponectin and globular domain (gAd) adiponectin and it was observed that HMW and gAd dose-dependently inhibited the expression of tumor necrosis factor (TNF)-α and interleukin (IL)-8, and the generation of 4-hydroxy-nonenal and reactive oxygen species (ROS) in 16HBECs, thereby blocking the upregulating effect of CSE on these factors...

OBJECTIVE: Whole-body vibration (WBV) is a popular fitness trend based on claims of increased muscle mass, weight-loss and reduced joint pain. Following its original implementation as a treatment to increase bone mass in patients with osteoporosis, WBV has been incorporated into clinical practice for musculoskeletal disorders, including back pain. However, our recent studies revealed damaging effects of WBV on joint health in a murine model. In this report, we examined potential mechanisms underlying disc degeneration following exposure of mice to WBV...
