Keramische Membranen auf Basis LPS-SiC: Schlickerentwicklung und Beschichtungsverfahren
… Phase Sintered Silicon Carbide" (LPS-SiC) erfüllt die Anforderungen sehr gut. Deshalb bestand das Ziel der Arbeit besteht darin, erstmals aus LPS-SiC asymmetrische keramische Membranen (grobporöses Substrat mit dünner, feinporiger Membran) herzustellen. Als Additivsystem fanden …

1,25- dihydroxycholecalciferol-glycoside supplementation for LPS - challenged broiler chickens
… of broilers challenged with lipopolysaccharides (LPS). At 20 days old, 144 male broilers were weighed and distributed in a completely randomized design with three treatments, eight replicates, and six birds per experimental unit. The treatments consisted in a basal diet without LPS administration …

Suppression of LPS-induced cytokines/chemokines production by CXCL1 siRNA
… (P. gingivalis ) / lipopolysaccharide (LPS) stimulates CXCL1 production in macrophages. The expression of CXCL1 increases inflammation and inflammatory diseases. However, little is known about the mechanism by which CXCL1 is related to different diseases. We studied the biological …

Hymenopterous parasites of lps spp. bark beetles (Coleoptera:Scolytidae) in Virginia
The pine engraver beetles (~ spp.:Coleoptera:Scolytidae) may be serious pests depending on certain prerequisite conditions. In their secondary or "normal" role they breed in slash and damaged, dying, and dead trees. The broods emerging from these sources normally attack similar material. When such …

BV-2 미세아교세포에서 PGE2 에 의한 LPS 유도 IFN-β생성 조절
… 그 작용 기전에 대해서는 아직 정확히 밝혀진 바가 없다. 본 연구는 PGE2 에 의한 LPS 유도 IFN-β생성 조절기전을 규명하기 위한 연구의 일환으로 TLRs신호전달 과정 중 PGE2 의 표적인자를 확인 하고자 하였다. BV-2 에서 PGE2 는 LPS 또는 poly(I:C) 로 유도된 IFN-β 의 생성을 억제하는 작용을 보였다. IFN-β 의 발현은 IRF3 complex, AP-1, NF-кB 등의 enhanceosome 전사인자 복합체에 의해서 조절된다고 알려져 있으나, PGE2 는 MAPKs 와 그 하위 …

TLR4 expression on equine B lymphocytes: a clue to LPS sensitivity?
… These bacteria express lipopolysaccharide (LPS) on their cell membranes, which is recognized by Toll-like receptor 4 (TLR4). In cases where epithelial barriers are compromised or breached LPS has the potential to enter circulation and cause the inflammatory symptoms seen with endotoxemia. …

Long-term effects of LPS and high-fat diet on dopaminergic neurodegeneration
… released by glia cells, could be mediating the LPS-induced dopaminergic neurodegeneration and that the chronic low-grade inflammatory state caused by diet-induced obesity would exacerbate LPS-induced neurodegeneration. To ascertain the participation of IL-1 beta, three strains of mice were …

Role of TRB3 in Glucose Enhancing Effect on LPS-induced NO Production
… NF-κB의 활성화를 저해하는 것으로 알려져 있다. 선행연구에서 포도당농도 변화 따른 LPS에 의해 유도되는 NO생성 변화를 관찰한 결과, TRB3 및 iNOS발현에는 역상관 관계가 있음을 확인한바 있다. 본 연구에서는 LPS에 의해서 활성화 되는 TLR4 signal을 중심으로 TRB3의 영향을 검토함으로써 고포도당에 의한 NO 생성 증폭 반응에서 TRB3의 역할을 확인하고자 했다. 포도당 농도를 달리한 조건하에서 Raw 264.7 세포에서 TLR4 하위단계인 MyD88 경로 그리고 TRIF 경로의 specific …

Investigating the Reconstitution and Function of Peritoneal Cavity Macrophages after LPS-induced Peritonitis
… macrophage population after lipopolysaccharide (LPS)-induced peritonitis. A double recombinase, GATA6 and Lyz-M genetically driven fate mapping mouse was engineered to report on the large peritoneal population in response to a biologically relevant dose of lipopolysaccharide. Spectral flow …

The role of TNFAIP1 in regulation of LPS/TNF-ɑ-induced signaling pathway
… proteinases (gingipains), lipopolysaccharide (LPS), capsule and fimbriae. The LPS plays an important role in periodontal disease by inducing inflammation via stimulation of some cytokines such as TNF-ɑ. TNF-ɑ can activate expression of early response genes in macrophages, including Tumor …

Temporal Transcriptional Regulation of IL-10-Induced Anti-Inflammatory Genes in LPS-Triggered Macrophages
… receptor 4 (TLR4) binding to lipopolysaccharide (LPS). IL-10 acts on these cells through the induced expression of genes that inhibit expression of select TLR-induced pro-inflammatory genes. Our understanding of the mechanisms by which cells respond to IL-10 with the anti-inflammatory response …

Role of Fas/FasL, inflammatory mediators and LPS-activated macrophages in human neutrophil apoptosis
… certain culture conditions. Lipopolysaccharide (LPS) originating from Gram-negative bacteria is often found at sites of inflammation. We have shown that LPS attenuated CH-11 - induced neutrophil apoptosis unless the Fas/FasL death receptor pathway was activated prior to the LPS signalling …

Cellular requirements for antibody production in a novel LPS-enhanced model of autoimmune myasthenia gravis
Bacterial lipopolysaccharide (LPS) is a T cell-independent adjuvant known to abrogate peripheral tolerance. For the first time, the potential of LPS to induce antigenspecific B cell responses to acetylcholine receptor (AChR) in myasthenia gravis (MG) was evaluated in wild type (WT), CD4-/-, and …

Regulation of Synergistic Inducible ABIN-3 Gene Expression in Response to IL-10 and LPS
… by pro-inflammatory stimuli, such as bacterial LPS, is mediated through changes in the expression of genes that function to promote inflammation. Pro-inflammatory signaling and gene expression is tightly regulated through the parallel induction of anti-inflammatory genes in response to the host …

Μελέτη των ιστολογικών βλαβών του κερατοειδούς από και τα συστατικά της slime - GLP και LPS
… (P.a.) and its components slime-GLP and LPS as well as the clinical aspects of the inducted lesions were studied. Experimental keratitis was induced (a) by a single intracorneal injection of live bacteria of the P.a. prototype strain PAC-IR (20-30 cell/per injection), (b) by a single …
