Avaliação da resposta inflamatória pulmonar induzida por lipopolissacarideos (LPS) em camundongos infectados com 2 diferentes cepas de Proteus mirabilis
(Universidade Federal de São Paulo, 2013-08-03)O Proteus mirabilis é um importante patógeno do trato urinário humano, envolvido especialmente em infecções hospitalares, afetando principalmente jovens do sexo masculino. Este microrganismo também tem sido apontado como ...

Avaliação dos efeitos dos constituintes de óleos essenciais (timol, carvacrol e p-cimeno) na inflamação pulmonar aguda induzida por instilação de LPS em camundongos
(Universidade Federal de São Paulo, 2015-05-05)The acute respiratory distress syndrome (ARDS) is characterized by a diffuse inflammatory response, due to activation of pro-inflammatory agents and oxidants. Despite the high mortality, which affects 40% of patients, there ...

B-1 cells temper endotoxemic inflammatory responses
(Elsevier B.V., 2011-03-01)Sepsis syndrome is caused by inappropriate immune activation due to bacteria and bacterial components released during infection. This syndrome is the leading cause of death in intensive care units. Specialized B-lymphocytes ...

BACTERIAL SENSING, CELL SIGNALING, and MODULATION of the IMMUNE RESPONSE DURING SEPSIS
(Lippincott Williams & Wilkins, 2012-09-01)Since the definition of systemic inflammatory response syndrome/sepsis was originally proposed, a large amount of new information has been generated showing a much more complex scenario of inflammatory and counterinflammatory ...

Chronic unpredictable stress exacerbates lipopolysaccharide-induced activation of nuclear factor-kappa B in the frontal cortex and hippocampus via glucocorticoid secretion
(Soc Neuroscience, 2006-04-05)Although the anti-inflammatory actions of glucocorticoids (GCs) are well established in the periphery, these stress hormones can increase inflammation under some circumstances in the brain. the transcription factor nuclear ...

Cocaine counteracts LPS-induced hypolocomotion and triggers locomotor sensitization expression
(Elsevier B.V., 2015-07-01)Neuroimmune signalling underlies addiction and comorbid depression. Clinical observations indicate that infections and chronic lesions are more frequent in drug users and elevated inflammatory states are evident in cocaine ...

Different inflammatory stimuli in the footpad of mice influence the kinetics of resident peritoneal cells
(Springer, 2012-11-01)Evidence from the literature that inflammation is a systemic biological phenomenon prompted us to investigate whether inoculation of different irritants to the footpad of mice might influence the kinetics of resident ...

Different mechanism of LPS-induced vasodilation in resistance and conductance arteries from SHR and normotensive rats
(Nature Publishing Group, 2002-09-01)1 the direct and endothelium-dependent effects of lipopolysaccharide (LPS) were investigated on resistance and conductance arteries from normotensive Wistar (NWR) and spontaneously hypertensive (SHR) rats.2 in both NWR and ...

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 ...

Efeito do tratamento com Eugenol e Dehidrodieugenol b, isolados das folhas de Nectandra lLeucantha (lauraceae), em modelo murino de inflamação pulmonar aguda induzida por instilação de LPS
(Universidade Federal de São Paulo (UNIFESP), 2019-12-18)Acute lung injury (ALI) is characterized by a diffuse inflammatory response, resulting from the application of proinflammatory and oxidante agents, which causes acute lung injury, followed by pulmonary remodeling. Several ...
