BACKGROUND: Human airway smooth muscle cells (ASMCs) may have a pro-inflammatory role through the release of inflammatory mediators. Increasing evidence indicates that human β-defensins (HBDs) are related to pathogenesis of asthma. OBJECTIVES: To examine the plasma level of HBD-1, -2 and -3 in asthmatic patients and the expression of their mouse orthologs in the lung tissue of a mouse model of chronic severe asthma. Further to investigate the effect of HBD-3 on the release of the pro-inflammatory cytokine IL-8 and to explore the mechanisms...

microRNA (miRNA) play critical roles in the pathological processes of diabetic retinopathy, including inflammatory responses, insulin signaling, and angiogenesis. In addition to their regulatory functions on gene expression, miRNA is considered as a potential therapeutic target, as well as a diagnostic marker for many diseases. Our understanding on the pathological mechanisms underlying diabetic retinopathy is still incomplete and additional investigations are required to develop novel therapeutic strategies...

IL-25 and IL-4 signaling in the setting of infection or allergic responses can drive Type 2 inflammation. IL-25 requires the IL-17 receptor B (IL-17Rb) to mediate signaling through nuclear factor kappa B transcriptional activation. Despite the known coexistence of these two cytokines in the Type 2 inflammatory environment, collaborative signaling between the IL-4 and IL-25 axes is poorly explored. Here we demonstrate IL-4 induction of both IL-25 and IL-17Rb protein in human lung tissue culture, primary alveolar macrophages, and the THP-1 monocytic cell line...

Extensive studies have been performed on acute mountain sickness (AMS), but biomarkers predicting AMS are lacking. Presently, the mainstay methods to identify AMS biomarkers include proteomic and genetic methods at high altitudes or in hypoxic simulated chambers. In the present study, we compared plasma cytokine profiles between AMS-susceptible individuals and AMS-resistant individuals at low altitude by cytokine array analysis. In total, 75 differentially expressed cytokines were identified between AMS-susceptible individuals and AMS-resistant individuals, most involved in inflammation...

Aberrantly activated CD4(+) T memory cells play a central role in the development of type-1-diabetes. Interleukin-7 promotes generation of autoimmune memory T cells and increased Interleukin-7 availability is associated with type-1-diabetes susceptibility. T-cell mediated immune pathology at onset of type-1-diabetes is well defined, but characteristics of long-term symptomatic disease stages remain largely elusive. In the present study memory CD4(+) T-cell activation and cytokine expression as well as sensitivity to Interleukin-7 in vitro were compared between patients with type-1-diabetes at clinical onset (n=25), long-term symptomatic disease (median duration 4...

It is recognized that T helper 2 (Th2) polarization plays a critical role in a large number of immune disorders. Yet, the remedies for reconciling the established Th2 polarization are still limited currently. Published data indicate that micro RNA-17-92 cluster is associated with the skewed immune response; 25 vitamin D3 (VD3) can regulate multiple bioactivities in the body. This study tests a hypothesis that VD3 facilitates the effect of specific immunotherapy (SIT) on Th2 response. We observed that treatment with either SIT or VD3 alleviated AR symptoms as well as reduced serum levels of specific IgE and T helper (Th) 2 cytokines, suppressed miR-19a (one of the members of the miR-17-92 cluster) and increased IL-10 in peripheral B cells, which was further improved in those AR patients treated with both SIT and VD3...

Background: Cardiac dysfunction is present in >40% of sepsis patients and is associated with mortality rates of up to 70%. Recent evidence suggests that glycolytic metabolism plays a critical role in host defense and inflammation. Activation of Toll-like receptors on immune cells can enhance glycolytic metabolism. This study investigated whether modulation of glycolysis by inhibition of hexokinase will be beneficial to septic cardiomyopathy. Methods: Male C57B6/J mice were treated with a hexokinase inhibitor (2-deoxy-D-glucose, 2-DG, 0...

Low vitamin D (VD) status potentiates experimental colitis, but the VD responsive cell in colitis has not been defined. We hypothesized that VD has distinct roles in colonic epithelial cells and in non-epithelial cells during colitis and tested this hypothesis by using mice with VD receptor (VDR) deletion from either colon epithelial cells (CEC-VDRKO) or non-intestinal epithelial cells (NEC-VDRKO). 8-wk-old mice were treated with 1.35% dextran sulfate sodium (DSS) for 5 days then killed 2 or 10 days after removing DSS...

Bovine mammary epithelial cells (bMECs) contribute to mammary gland defense against invading pathogens, such as Staphylococcus aureus (intracellular facultative), which is recognized by TLR2. In a previous report, we showed that sodium octanoate [NaO, a medium chain fatty acid (C8)] induces (0.25 mM) or inhibits (1 mM) S. aureus internalization into bMECs and differentially regulates the innate immune response (IIR). However, the molecular mechanisms have not been described, which was the aim of this study...

Early-life wheezing associated respiratory tract infection by rhinovirus (RV) is considered a risk factor for asthma development. We have shown that RV infection of 6 day-old BALB/c mice, but not mature mice, induces an asthma-like phenotype which is associated with an increase in the population of type 2 innate lymphoid cells (ILC2s) and dependent on IL-13 and IL-25. We hypothesize that ILC2s are required and sufficient for development of the asthma-like phenotype in immature mice. Mice were infected with RV1B on day 6 of life and treated with vehicle or a chemical inhibitor of retinoic acid receptor-related orphan receptor (ROR)-α, SR3335 (15 mg/kg/day intraperitoneally for 7 days)...

Pyrazinoic acid (PA) is structurally similar to nicotinic acid which acts on G-protein-coupled receptor (GPR109A). GPR109A expresses in colonic and intestinal epithelial sites, and involves in DNA methylation and cellular apoptosis. Therefore, it may be assumed that PA has similar action like nicotinic acid and may be effective against colorectal carcinoma (CRC). CRC was produced via subcutaneous injection of dimethylhydrazine (DMH) at 40 mg/kg body weight once in a week for four weeks. After that, PA was administered orally at two doses of 10 and 25 mg/kg daily for 15 days to observe the antiproliferative effect...

BACKGROUND AND OBJECTIVE: Vitamin D-1,25(OH)2 D3 or 1,25D3-maintains healthy osseous tissue, stimulates the production of the antimicrobial peptide cathelicidin and has anti-inflammatory effects, but it can cause hypercalcemia. Evidence links diminished serum levels of 1,25D3 with increased gingival inflammation. Periodontitis progression is associated with increased local production of inflammatory mediators by immune cells and gingival fibroblasts. These include interleukin (IL)-6, a regulator of osteoclastic bone resorption, and the neutrophil chemoattractant IL-8, both regulated by signaling pathways, including NF-κB and MAPK/AP-1...
