Polyphenol extracts interfere with bacterial lipopolysaccharide in vitro and decrease postprandial endotoxemia in human volunteers
(Elsevier Science, 2016-10)
The intestinal absorption of bacterial lipopolysaccharide (LPS) and dietary fat has been implicated in the development of metabolic endotoxemia. This study first compared the ability of polyphenol extracts from grape, ...
Interleukin-6 and lipopolysaccharide modulate hepcidin mRNA expression by Hepg2 cells
(2012)
Iron homeostasis is controlled by hepcidin (Hpc) as well as other ways. Hpc expression is regulated by iron (Fe) storage and by inflammation, but the joint effect of both stimuli remains unclear. We studied the modulatory ...
Lipopolysaccharide from porphyromonas gingivalis, but not from porphyromonas endodontalis, induces macrophage M1 profile
(MDPI, 2022)
Apical Lesions of Endodontic Origin (ALEO) are initiated by polymicrobial endodontic canal infection. Porphyromonas gingivalis (Pg) and Porphyromonas endodontalis (Pe) lipopolysaccharides (LPS) can induce a pro-inflammatory ...
Lipopolysaccharide activates toll like receptor 4 and prevents cardiac fibroblast to myofibroblast differentiation
(Springer, 2017)
Bacterial lipopolysaccharide (LPS) is a known ligand of Toll-like receptor 4 (TLR4) which is expressed in cardiac fibroblasts (CF). Differentiation of CF to cardiac myofibroblasts (CMF) is induced by transforming growth ...
Short-term lipopolysaccharide stimulation induces differentiation of murine bone marrow-derived dendritic cells into a tolerogenic phenotype
(2007)
Dendritic cells (DCs) are professional, antigen-presenting cells, which induce and regulate T cell reactivity. DCs are crucial in innate and adaptive immune responses, and are also involved in central and peripheral tolerance ...
Response to lipopolysaccharide in Octodon degus pups produces age-related sickness behavior but does not have effects in juveniles
(Wiley-Blackwell, 2019)
During vertebrate development, the immune function is inefficient and is mainly controlled by innate defense. While there have been detailed studies of various aspects of innate immune function, the effects of this function ...
O-antigen chain-length distribution in Salmonella enterica serovar Enteritidis is regulated by oxygen availability
(Elsevier, 2016)
Lipopolysaccharide (LPS) consists of three covalently linked domains: the lipid A, the core region and the O antigen (OAg), consisting of repeats of an oligosaccharide. Salmonella enterica serovar Enteritidis (S. Enteritidis) ...
T-lymphocyte phenotype and function triggered by Aggregatibacter actinomycetemcomitans is serotype-dependent
(Blackwell Munksgaard, 2015)
& Sons Ltd. Background and Objective: Based on lipopolysaccharide (LPS) antigenicity, different Aggregatibacter actinomycetemcomitans serotypes have been described. Serotype b strains have demonstrated a stronger capacity ...
RpoS and RpoN are involved in the growth-dependent regulation of rfaH transcription and O antigen expression in Salmonella enterica serovar typhi
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004-01)
We reported earlier that the production of 0 antigen lipopolysaccharide (LPS) by Salmonella enterica serovar Typhi (Salmonella typhi) increases at the onset of stationary phase and correlates with a growth-regulated ...
