Differential expression of toll-like receptor signaling cascades in LPS-tolerant human peripheral blood mononuclear cells
(Elsevier B.V., 2011-03-01)
Pre-exposure to low doses of LPS induces resistance to a lethal challenge, a phenomenon known as endotoxin tolerance. in this study, tolerance was induced in human PBMC by culturing cells with 1 ng/mL LPS for 48 h. Cells ...
Lipopolysaccharides and trophic factors regulate the LPS receptor complex in nodose and trigeminal neurons
(Elsevier, 2014-09)
Binding of bacterial lipopolysaccharides (LPS) to toll-like receptor 4 (TLR4) triggers an innate immunoresponse associated with pain and inflammation. The expression, and to a greater extent the regulation of TLR4 and its ...
Perfil de expressão gênica da via de sinalização dos receptores do tipo Toll em células mononucleares do sangue periférico humanas tolerantes ao LPS
(Universidade Federal de São Paulo (UNIFESP), 2010-06-30)
Pre-exposure to low doses of LPS induces resistance to a lethal challenge, a phenomenon known as endotoxin tolerance. In this study, tolerance was induced in human PBMC by culturing cells with 1 ng/mL LPS for 48 h. Cells ...
Respuesta inflamatoria y expresión de receptores de estrógeno en cultivos de fibroblastos pulpares de rata in vitro
(Sociedad Argentina de Investigación Odontológica, 2018)
OBJETIVO El objetivo de este trabajo fue evaluar la respuesta inflamatoria y la expresión de receptores de estrógeno (ER) en fibroblastos pulpares in vitro. MÉTODOS Se utilizaron cultivos primarios de fibroblastos de rata ...
Avaliação ex vivo da expressão de TLR-2 e TLR-4 em leucócitos de equinos e sua relação com a tolerância à endotoxina
(Universidade Estadual Paulista (Unesp), 2009-07-28)
A endotoxemia é um importante distúrbio sistêmico que se origina da resposta do hospedeiro a um componente das bactérias Gram-negativas, o lipopolissacarídeo (LPS) ou endotoxina, que é liberado após bacteriólise ou rápida ...

LPS a través de TLR4 previene la diferenciación de fibroblasto a miofibroblasto cardiaco inducida por TGF-[beta]1
(Universidad de Chile, 2014)
La diferenciación de fibroblastos cardiacos (FC) a miofibroblastos cardiacos (MFC)
es gatillada por TGF-β1, la cual señaliza principalmente a través de las proteínas
Smad. Los MFC muestran como principal característica ...
Lipopolysaccharide-induced expression of cell surface receptors and cell activation of neutrophils and monocytes in whole human blood
(Associação Brasileira de Divulgação Científica, 2010-09-01)
Lipopolysaccharide (LPS) activates neutrophils and monocytes, inducing a wide array of biological activities. LPS rough (R) and smooth (S) forms signal through Toll-like receptor 4 (TLR4), but differ in their requirement ...
Cannabinoid CB1 receptor restrains accentuated activity of hypothalamic corticotropin-releasing factor and brainstem tyrosine hydroxylase neurons in endotoxemia-induced hypophagia in rats
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
It is well known that endocannabinoids play an important role in the regulation of food intake and body weight. Endocannabinoids and cannabinoid receptors are found in the hypothalamus and brainstem, which are central areas ...
