INTRODUCTION: Antitumor necrosis factor (anti-TNF) medications are known to be highly efficacious in persons with moderate-to-severe inflammatory bowel disease (IBD). There is a paucity of data from population-based sources to elucidate persistence with these medications in the general population of IBD. Discontinuation of anti-TNF therapy is a marker of lack of effectiveness, intolerance, and patient/physician practice preferences. METHODS: We identified all persons with IBD in Manitoba who were dispensed infliximab (IFX) and adalimumab (ADA) between 2001 and 2014...

PURPOSE: Cardiovascular complications are amongst the leading causes of morbidity and mortality in diabetes mellitus. Despite the beneficial effects of subcutaneous insulin administration, reports suggest that the therapy itself precipitates cardiovascular risks due to the high insulin concentration administered. It is therefore necessary to seek alternative insulin administration routes that may bypass the undesirable effects associated with high plasma insulin concentration. Accordingly, the study investigated the effect of a novel transdermal pectin-insulin patch on selected cardiovascular function markers in diabetes...

Obesity and alcohol consumption synergistically promote steatohepatitis, and neutrophil infiltration is believed to be associated with steatosis. However, the underlying mechanisms remain obscure. Peroxisome proliferator-activated receptor-gamma (PPARγ) plays a complex role in lipid metabolism and inflammation, therefore, the purpose of this study was to dissect its role in regulating steatosis and neutrophil infiltration in a clinically relevant mouse steatohepatitis model of 3-month high-fat diet (HFD) feeding plus a binge of ethanol (HFD -plus-binge ethanol)...

Interleukin 17 (IL-17) is an important inducer of tissue inflammation and is involved in numerous autoimmune diseases. However, how its signal transduction is regulated is not well understood. Here, we report that nuclear Dbf2-related kinase 1 (NDR1) functions as a positive regulator of IL-17 signal transduction and IL-17-induced inflammation. NDR1 deficiency or knockdown inhibits the IL-17-induced phosphorylation of p38, ERK1/2, and p65 and the expression of chemokines and cytokines, whereas the overexpression of NDR1 promotes IL-17-induced signaling independent of its kinase activity...

Neutrophils are generally the first immune cells recruited during the development of sterile or microbial inflammation. As these cells express many innate immune receptors with the potential to directly recognize microbial or endogenous signals, we set out to assess whether their functions are locally influenced by the signals present at the onset of inflammation. Using a mouse model of peritonitis, we demonstrate that neutrophils elicited in the presence of C-type lectin receptor ligands have an increased ability to produce cytokines, chemokines, and lipid mediators in response to subsequent TLR stimulation...

Glomerular damage mediated by glomerulus-infiltrating myeloid-derived cells is a key pathogenic event in lupus nephritis (LN), but the process is poorly understood. Confocal microscopy of kidney sections and flow cytometry analysis of glomerular cells from magnetic bead-purified glomeruli have identified glomerulus-infiltrating leukocyte populations in NZM2328 (NZM) lupus-prone mice with spontaneous chronic glomerulonephritis (GN) and anti-glomerular basement membrane-induced nephritis. The occurrence of a major glomerulus-infiltrating CD11b(+)F4/80(-)I-A(-) macrophage population exhibiting the markers programmed death ligand-1 (PD-L1), Mac-2, and macrophage mannose receptor (CD206) and producing Klf4, Il10, Retnla, Tnf, and Il6 mRNA, which are known to be expressed by alternatively activated (M2b) macrophages, correlated with proteinuria status...

Sinigrin (2-propenyl glucosinolate) is found mainly in broccoli, brussels sprouts, and black mustard seeds. Recently, sinigrin has received attention for its role in disease prevention and health. This study investigated the effect of sinigrin on macrophage function, including the activity of Nod-like receptor protein 3 (NLRP3) inflammasome. In a concentration-dependent manner, sinigrin inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO) production and the expression of COX-2 and prostaglandin E2 (PGE2) in RAW 264...

Regulatory T cells (Tregs) are critical for self-tolerance. While adoptive transfer of expanded Tregs limits graft-versus-host disease (GVHD) after hematopoietic cell transplantation (HCT), ex vivo generation of large numbers of functional Tregs remains difficult. Here, we demonstrate that in vivo targeting of the TNF superfamily receptor TNFRSF25 using the TL1A-Ig fusion protein, along with IL-2, resulted in transient but massive Treg expansion in donor mice, which peaked within days and was nontoxic. Tregs increased in multiple compartments, including blood, lymph nodes, spleen and colon (a GVHD target tissue)...

Streptococcosis due to the bacterium Streptococcus agalactiae (S. agalactiae) has resulted in enormous economic losses in aquaculture worldwide, especially in the tilapia culture industry. Previously, there were limited vaccines that could be employed against streptococcosis in tilapia. This study aimed to develop a vaccine candidate using the glyceraldehyde-phosphate dehydrogenase protein (GapA) of S. agalactiae encoded by the gapA gene. Tilapia were intraperitoneally injected with PBS, PBS + Freund's adjuvant, PBS + Montanide's adjuvant, GapA + Freund's adjuvant, GapA + Montanide's adjuvant, killed S...
