Inflammation bowl disease

Nathan Karin, Hila Razon
Chemokines are mostly known for their chemotactic properties, and less for their ability to direct the biological function of target cells, including T cells. The current review focuses on a key chemokine named CXCL10 and its role in directing the migratory propertied and biological function of CD4+ and CD8+ T cells in the context of cancer and inflammatory autoimmunity. CXCR3 is a chemokine receptor that is abundant on CD4+ T cells, CD8+ T cells and NK cells. It has three known ligands: CXCL9, CXCL10 and CXCL11...

The pathogenesis of many diseases is driven by the interactions between helper T (TH ) cells and macrophages. The phenotypes of these cells are functional dichotomies that are persuaded according to the surrounding milieu. In both multiple sclerosis and the experimental autoimmune encephalomyelitis (EAE) model, TH 1 and TH 17 cells propagate autoimmune signaling and inflammation in the peripheral lymphoid tissues. In turn, this proinflammatory repertoire promotes the classical activation, formerly the M1-type, macrophages...

BACKGROUND: Patients are at increased risk of disease recurrence after surgical treatment of Crohn's disease. Endoscopic detection of postoperative, ileo-colonic inflammation is well established, but the potential of pan-intestinal endoscopy is yet unknown. METHODS: This prospective multicenter pilot study assessed the value of pan-intestinal capsule endoscopy using a colon capsule endoscope for the detection of inflammatory recurrence of Crohn´s disease. Patients who had been operatively treated for Crohn´s disease were included...

Carbon nanomaterials have been used to treat neurodegenerative diseases and neural disorders due to their diverse molecular structures. Corannulene is a three-dimensional π-bowl carbon nanomaterial that is different from planar PAHs, fullerenes and carbon nanotubes, but little is known about its biological functions. Herein, corannulene was functionalized with mPEG-DESP to prepare PEGylation corannulene nanoparticles (PEGylation CoNps). The synthesized PEGylation CoNps shows enhanced solubility and reduced aggregation when compared corannulene...

Musculoskeletal diseases have been associated with inflammatory cytokine action, particularly action by TNF-α and IL-1β. These inflammatory cytokines promote apoptosis and senescence of cells in diseased tissue and extracellular matrix breakdown. Stem cell-based therapies are being considered for the treatment of musculoskeletal diseases, but the presence of these inflammatory cytokines will have similar deleterious action on therapeutic cells delivered to these environments. Methods that prevent inflammatory-induced apoptosis and proinflammatory signaling, in cell and pathway-specific manners are needed...

Human infections with highly pathogenic avian influenza A (H5N1) virus are frequently fatal but the mechanisms of disease remain ill-defined. H5N1 infection is associated with intense production of proinflammatory cytokines, but whether this cytokine storm is the main cause of fatality or is a consequence of extensive virus replication that itself drives disease remains controversial. Conventional intratracheal inoculation of a liquid suspension of H5N1 influenza virus in nonhuman primates likely results in efficient clearance of virus within the upper respiratory tract and rarely produces severe disease...

Multiple sclerosis (MS) is a common neurodegenerative disease and remains an unmet clinical challenge. In MS, an autoimmune response leads to immune cell infiltration, inflammation, demyelination, and lesions in central nervous system (CNS) tissues resulting in tremors, fatigue, and progressive loss of motor function. These pathologic hallmarks are effectively reproduced in the murine experimental autoimmune encephalomyelitis (EAE) model. The stromal vascular fraction (SVF) of adipose tissue is composed of adipose-derived stromal/stem cells (ASC), adipocytes, and various leukocytes...

Tolerance to environmental antigens that encounter the organism at interfaces like skin or gut prevents deleterious systemic immune responses. The aim of this study was to analyze whether and how low doses of haptens, by entry through the skin or gastrointestinal tract, affect the outcome of the predominantly Th1/Th17-mediated 2,4,6-trinitro-benzenesulfonic acid-induced colitis, which mimics an autoimmune bowl disease in man. Epicutaneous and oral applications of low doses of the allergen resulted in the induction of low-zone tolerance (LZT) and protected from colitis development, demonstrated by a significantly reduced inflammatory response of the gut in vivo...

Multiple sclerosis is an autoimmune disease that affects the white matter of the central nervous system and involves inflammation and demyelination. The recent advances in our understanding of adipose-derived stromal/stem cells (ASCs) and the utilization of these cells in clinical settings to treat diseases have made it essential to identify the most effective ASCs for therapy. Studies have not yet investigated the impact of obesity on the therapeutic efficacy of ASCs. Obesity is characterized by adipocyte hyperplasia and hypertrophy and can extend to metabolic and endocrine dysfunction...

Necrotizing enterocolitis remains one of the most vexing problems in the neonatal intensive care unit. Risk factors for NEC include prematurity, formula feeding, and inappropriate microbial colonization of the GI tract. The pathogenesis of NEC is believed to involve weakening of the intestinal barrier by perinatal insults, translocation of luminal bacteria across the weakened barrier, an exuberant inflammatory response, and exacerbation of the barrier damage by inflammatory factors, leading to a vicious cycle of inflammation-inflicted epithelial damage...

Ongoing troublesome bowel symptoms despite quiescent inflammatory disease are a frequent management challenge when caring for patients with inflammatory bowel disease (IBD). Even when active disease has been excluded the prevalence of residual gastrointestinal symptoms is surprisingly high and the cause often obscure. The presence of a concurrent functional disorder such as irritable bowel syndrome (IBS) is associated with worse quality of life, worse physical functioning, higher prevalence of anxiety and greater health care utilization...

Identifying neutrophils lays a crucial foundation for diagnosing acute inflammation diseases. But, such computerized methods on the commonly used H&E staining histology tissue images are lacking, due to various inherent difficulties of identifying cells in such image modality and the challenge that a considerable portion of neutrophils do not have a "textbook" appearance. In this paper, we propose a new method for identifying neutrophils in H&E staining histology tissue images. We first segment the cells by applying iterative edge labeling, and then identify neutrophils based on the segmentation results by considering the "context" of each candidate cell constructed by a new Voronoi diagram of clusters of other neutrophils...

Multiple sclerosis (MS) is a common neurodegenerative disease that presents after an auto-reactive immune response against constituents of the central nervous system. Demyelination, inflammation, and white matter lesions are all hallmarks of this disease. Clinical research supports the use of mesenchymal stem cells (MSCs) as therapy for MS to ameliorate symptoms and pathology. MSCs can be isolated from multiple tissues, including adipose and bone marrow, and are able to migrate to sites of pathology, release anti-inflammatory factors, and provide immunomodulatory and neuroprotective effects once administered...

Alterations in numerous signal transduction pathways and aberrant activity of specific kinases have been identified in multiple cell and mouse models of Huntington's disease (HD), as well as in human HD brain. The balance and integration of a network of kinase signalling pathways is paramount for the regulation of a wide range of cellular and physiological processes, such as proliferation, differentiation, inflammation, neuronal plasticity and apoptosis. Unbalanced activity within these pathways provides a potential mechanism for many of the pathological phenotypes associated with HD, such as transcriptional dysregulation, inflammation and ultimately neurodegeneration...

OBJECTIVE: 17β-Estradiol (E2) offers cardiovascular protection in young female animals and postmenopausal women. In contrast, randomized trials of menopausal hormones performed in older women have shown harm or no cardiovascular benefit. We hypothesize that E2 effects on vascular inflammation are age dependent. APPROACH AND RESULTS: Young (10 weeks) and aged (52 weeks) female C57BL/6 mice were used as source for primary cultures of bone marrow-derived macrophages (BMMs) and vascular smooth muscle cells (VSMCs)...

Multiple sclerosis (MS), characterized by chronic inflammation, demyelination, and axonal damage, is a complicated neurological disease of the human central nervous system. Recent interest in adipose stromal/stem cell (ASCs) for the treatment of CNS diseases has promoted further investigation in order to identify the most suitable ASCs. To investigate whether MS affects the biologic properties of ASCs and whether autologous ASCs from MS-affected sources could serve as an effective source for stem cell therapy, cells were isolated from subcutaneous inguinal fat pads of mice with established experimental autoimmune encephalomyelitis (EAE), a murine model of MS...

Multiple lines of inquiry have suggested that a high degree of inflammation in early lactation cows is associated with low productivity and increased disease incidence. In addition, some small studies have suggested that milk production increases in response to antiinflammatory treatment in the first week of lactation. Our objective was to determine if administration of sodium salicylate (SS), a nonsteroidal antiinflammatory drug (NSAID), in the first week of lactation changes whole-lactation productivity and retention in the herd...

There is a significant clinical need for effective therapies for primary progressive multiple sclerosis, which presents later in life (i.e., older than 50 years) and has symptoms that increase in severity without remission. With autologous mesenchymal stem cell therapy now in the early phases of clinical trials for all forms of multiple sclerosis (MS), it is necessary to determine whether autologous stem cells from older donors have therapeutic effectiveness. In this study, the therapeutic efficacy of human adipose-derived mesenchymal stem cells (ASCs) from older donors was directly compared with that of cells from younger donors for disease prevention...
