Vedolizumab, a gut-specific biological treatment for inflammatory bowel disease (IBD), is an antibody that binds to the α₄β₇ integrin and blocks T-cell migration into intestinal mucosa. We aimed to investigate chemokine levels in serum of IBD-patients treated with vedolizumab. In this pilot study, we included 11 IBD patients (8 Crohn's disease, 3 ulcerative colitis) previously non-respondent to anti-tumor necrosis factor (TNF)-agents. Patients received vedolizumab at week 0, 2 and 6 and were evaluated for clinical efficacy at week 10...

Activity of rheumatoid arthritis (RA) has been evaluated by various biomarkers including matrix metalloproteinase (MMP)-3, but the relationship between the levels of biomarkers and elevation of pulmonary artery systolic pressure (PAs) has not been evaluated in detail. We sought to determine the utility of MMP-3 with other biomarkers for the prediction of PAs in patients with RA. Blood samples for biomarkers and echocardiography were obtained in 100 consecutive patients with RA. PAs was measured by continuous-wave Doppler echocardiography and was correlated with laboratory findings...

Protein cysteinyl residues are the mediators of hydrogen peroxide (H2O2)-dependent redox signaling. However, site-specific mapping of the selectivity and dynamics of these redox reactions in cells poses a major analytical challenge. Here we describe a chemoproteomic platform to systematically and quantitatively analyze the reactivity of thousands of cysteines toward H2O2 in human cells. We identified >900 H2O2-sensitive cysteines, which are defined as the H2O2-dependent redoxome. Although redox sites associated with antioxidative and metabolic functions are consistent, most of the H2O2-dependent redoxome varies dramatically between different cells...

Chromogranin-A (CHGA) is a prohormone secreted by neuroendocrine cells and is a precursor of several bioactive peptides, which are implicated in different and distinctive biological and immune functions. Chromofungin (CHR: CHGA47-66) is a short peptide with antimicrobial effects and encodes from CHGA exon-IV. Inflammatory bowel disease (IBD) is characterized by alterations in the activation of pro-inflammatory pathways, pro-inflammatory macrophages (M1), and nuclear transcription factor kappa B (NF-κB) signaling leading to the perpetuation of the inflammatory process...

BACKGROUND & AIMS: Administration of tryptophan, and some of its metabolites, reduces the severity of colitis in mice, whereas removing tryptophan from the diet increases susceptibility to colitis. Transfer of the intestinal microbiome can increase susceptibility of mice to colitis. We aimed to systematically evaluate serum levels of tryptophan and its metabolites in patients with inflammatory bowel diseases (IBD), and study their association with clinical and serologic features. METHODS: We studied 535 consecutive patients with IBD (211 with ulcerative colitis [UC], 234 with Crohn's disease [CD]; 236 male), enrolled in Germany from August 2013 through April 2014 and followed until July 2016...

ETHNOPHARMACOLOGICAL RELEVANCE: Clitoria ternatea Linn. (C. ternatea) is a traditionally used herb in arthritis, and its anti-arthritic activity has been attributed to polyphenols (e.g. quercetins) from its flower petal. AIM OF THE STUDY: The present study was designed to investigate whether C. ternatea or quercetin-3ß-D-glucoside (QG) support the antibody mediated TNFα-receptor 1 (TNFR1) neutralization to ameliorate arthritis in mice. MATERIALS AND METHODS: Development of collagen-induced arthritis (CIA) in male Swiss mice (20-22g, 3-4 weeks of age) was followed by estimation of synovial polymorphonuclear cell (PMN) accumulation (in terms of myeloperoxidase activity), synovial and systemic release of cytokines, chemokines and C-reactive protein (CRP) by enzyme-linked immunosorbent assay (ELISA), biochemical estimation of synovial free radical generation and antioxidant status, as well as immunoblot assessment of synovial TNFR1, toll-like receptor 2(TLR2), cyclooxygenase-2(COX-2) and inducible nitric oxide synthase (iNOS) expression; and zymographic analysis of synovial matrix-metalloprotease-2 (MMP-2) activity...

Recent discoveries implicate the classical complement cascade in normal brain development and in disease. Complement proteins C1q, C3, and C4 participate in synapse elimination, tagging inappropriate synaptic connections between neurons for removal by phagocytic microglia that exist in a special, highly phagocytic state during the synaptic pruning period. Several neurodevelopmental disorders, such as schizophrenia and autism, are thought to be caused by an imbalance in synaptic pruning, and recent studies suggest that dysregulation of complement could promote this synaptic pruning imbalance...

Phthalate esters (PAEs), a family of emerging environmental contaminants, have been frequently detected in soils and water. However, intensive studies on the toxicity of PAEs have focused on growth response of terrestrial and aquatic animals, while only limited attention has been paid to aquatic plants, especially phytoplankton, the primary producer in aquatic ecosystems. Therefore, the acute toxic effects and underlying mechanisms of dibutyl phthalate (DBP) at different concentrations (0-20mgL(-1)) on two typical freshwater algae (Scenedesmus obliquus and Chlorella pyrenoidosa) were investigated...

Polyclonal antibodies raised in Balb-c mice against BnSP-7, a Lys-49 phospholipase A2, were used to measure cross reactivity against other snake venoms. Using ELISA, these antibodies were able to recognize PLA2s isoforms present in venoms of botropic snakes at 1:6400, 1:3200 and 1:100 ratios (w/w). These antibodies highly recognized proteins of low molecular weight (∼14,000) from crude snake venom Bp and Bm by Western Blotting. PLA2 these venoms, by alignment of primary structures demonstrated high identity with BnSP-7 PLA2, especially in the C-terminal region...
