Local IL-17 Production Exerts a Protective Role in Murine Experimental Glomerulonephritis.

IL-17 is a pro-inflammatory cytokine implicated in the pathogenesis of glomerulonephritis and IL-17 deficient mice are protected from nephrotoxic nephritis. However, a regulatory role for IL-17 has recently emerged. We describe a novel protective function for IL-17 in the kidney.

Renal participation of myeloperoxidase in antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis.

Myeloperoxidase (MPO) is an important neutrophil lysosomal enzyme, a major autoantigen, and a potential mediator of tissue injury in MPO-ANCA-associated vasculitis (MPO-AAV) and glomerulonephritis. Here we examined MPO deposition in kidney biopsies from 47 patients with MPO-AAV. Leukocyte accumulation and fibrin deposition consistent with cell-mediated immunity was a major feature.

Endogenous Toll-Like Receptor 9 Regulates AKI by Promoting Regulatory T Cell Recruitment.

Toll-like receptor 9 (TLR9) enhances proinflammatory responses, but whether it can act in a regulatory capacity remains to be established. In experimental murine AKI induced by cisplatin, Tlr9(-/-) mice developed enhanced renal injury and exhibited fewer intrarenal regulatory T cells (Tregs) compared with genetically intact mice. A series of reconstitution and depletion studies defined a role for TLR9 in maintaining Treg-mediated homeostasis in cisplatin-induced AKI.

A clinical study of the LiVac laparoscopic liver retractor system.

Background: All retractors for laparoscopic operations on the gallbladder or stomach apply an upward force to the under-surface of the liver or gallbladder, most requiring an additional skin incision. The LiVac laparoscopic liver retractor system (LiVac retractor) comprises a soft silicone ring attached to suction tubing and connected to a regulated source of suction. The suction tubing extends alongside existing ports.

Myeloperoxidase Peptide-Based Nasal Tolerance in Experimental ANCA-Associated GN.

Less toxic treatment options for patients with myeloperoxidase (MPO)-ANCA-associated GN are needed. Using an established murine model of focal necrotizing GN mediated by autoimmunity to MPO (autoimmune anti-MPO GN), we assessed the capacity for nasal tolerance induced by nasal insufflation of the immunodominant nephritogenic MPO peptide (MPO409-428) to attenuate this disease. Compared with mice that received an irrelevant immunodominant ovalbumin (OVA) peptide, OVA323-339, mice that received MPO409-428 were protected from the development of humoral and cell-mediated autoimmunity to full-length MPO and the development of GN.

Mouse models of anti-neutrophil cytoplasmic antibody-associated vasculitis.

Inflammation of blood vessels (vasculitis) results from many pathological processes and is found in many different diseases. However, in most situations, the pathological processes inducing vasculitis are unknown. The discovery of anti-neutrophil cytoplasmic autoantibodies (ANCAs) in the 1980s opened the door for studies that eventually led to the description of a new previously undescribed disease, ANCA-associated vasculitis (AAV).

(E)-α,β-unsaturated amides from tertiary amines, olefins and CO via Pd/Cu-catalyzed aerobic oxidative N-dealkylation.

A novel Pd/Cu-catalyzed chemoselective aerobic oxidative N-dealkylation/carbonylation reaction has been developed. Tertiary amines are utilized as a "reservoir" of "active" secondary amines in this transformation, which inhibits the formation of undesired by-products and the deactivation of the catalysts. This protocol allows for an efficient and straightforward construction of synthetically useful and bioactive (E)-α,β-unsaturated amide derivatives from easily available tertiary amines, olefins and CO.

Identification of prostate cancer LncRNAs by RNA-Seq.

Purpose: To identify prostate cancer lncRNAs using a pipeline proposed in this study, which is applicable for the identification of lncRNAs that are differentially expressed in prostate cancer tissues but have a negligible potential to encode proteins.

Materials And Methods: We used two publicly available RNA-Seq datasets from normal prostate tissue and prostate cancer. Putative lncRNAs were predicted using the biological technology, then specific lncRNAs of prostate cancer were found by differential expression analysis and co-expression network was constructed by the weighted gene co-expression network analysis.

TUBB3/βIII-tubulin acts through the PTEN/AKT signaling axis to promote tumorigenesis and anoikis resistance in non-small cell lung cancer.

βIII-tubulin (encoded by TUBB3) expression is associated with therapeutic resistance and aggressive disease in non-small cell lung cancer (NSCLC), but the basis for its pathogenic influence is not understood. Functional and differential proteomics revealed that βIII-tubulin regulates expression of proteins associated with malignant growth and metastases. In particular, the adhesion-associated tumor suppressor maspin was differentially regulated by βIII-tubulin.

T cell mediated autoimmune glomerular disease in mice.

Many forms of glomerulonephritis are mediated by autoimmunity. While autoantibodies are often pathogenic, cell-mediated immunity plays an important role in a number of forms of rapidly progressive glomerulonephritis. This unit describes the induction of cell-mediated autoimmune glomerular disease in mice.

ALDH1A1 mediates resistance of diffuse large B cell lymphoma to the CHOP regimen.

Although there have been substantial advances in our knowledge of the resistance of diffuse large B cell lymphoma (DLBCL) to chemotherapy, there are few efficient treatment strategies for recurrent/refractory DLBCL. The aim of this study was to investigate the role of aldehyde dehydrogenase (ALDH) 1A1 in the resistance of diffuse large B cell lymphoma to the chemotherapeutic mixture consisting of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). The involvement of ALDH1A1 in DLBCL was elucidated by knockdown and pharmacologic inhibition; Cell Counting Kit-8 (CCK-8) and clone formation assays were used to determine its role in CHOP sensitivity and clone formation ability.

Relationship between polymorphism of angiotensin-converting enzyme gene insertion/deletion and risk of hepatocellular carcinoma in a Chinese Dai population.

Introduction: The angiotensin-converting enzyme gene (ACE) is directly involved in the process of cancer cell proliferation, differentiation, apoptosis and angiogenesis. It also plays a vital role in inducing liver fibrosis and developing hepatocellular carcinoma (HCC). The aim of this study was to investigate the relationship between ACE insertion/deletion (I/D) polymorphism and the risk of HCC in a Chinese Dai population.

Intracranial abscess in Ectopia Cordis.

We present a case of intracranial abscess in a young female with Ectopia Cordis, an exceptionally rare cardiac condition. The neurosurgical implication is the predisposition to intracranial abscess formation. A heightened awareness of this association will aid diagnosis in similar clinical scenarios.

Antiinflammatory effects of orientin-2"-O-galactopyranoside on lipopolysaccharide-stimulated microglia.

Microglia activation-mediated neuroinflammation plays an important role in the pathogenesis of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, and human immunodeficiency virus (HIV)-associated dementia. Inhibition of microglia activation may alleviate neurodegeneration under neuroinflammatory conditions. In the present study, we compared three flavone C-glycosides extracted from Trollius chinensis BUNGE using a cell-based assay to evaluate their antiinflammatory effects on microglial cells.

FcγRIIB regulates T-cell autoreactivity, ANCA production, and neutrophil activation to suppress anti-myeloperoxidase glomerulonephritis.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis involves innate and adaptive immune cells in the induction of autoimmunity and in autoimmune effector responses. Most Fcγ receptors (FcγRs) activate immune cells, but FcγRIIB, found in humans and mice on B cells and innate cells, is an inhibitory receptor. Here we tested whether endogenous FcγRIIB negatively regulates autoreactivity and effector responses in experimental anti-myeloperoxidase (MPO) glomerulonephritis, using wild-type and FcγRIIB(-/-) mice.

Seasonal and spatial variations in microbial activity at various phylogenetic resolutions at a groundwater - surface water interface.

We investigated the seasonal and spatial variation in activity and density of the metabolically active in situ microbial community (AIMC) at a landfill leachate-impacted groundwater - surface water interface (GSI). A series of AIMC traps were designed and implemented for AIMC sampling and microbial activity and density examinations. Measurements were made not only at the level of bacterial domain but also at the levels of alphaproteobacterial Rhizobiales order and gammaproteobacterial Pseudomonas genus, both of which included a large number of iron-oxidizing bacteria as revealed from previous analysis.
