J. appl. oral sci; 25 (2), 2017
Abstract Natural compounds capable of modulating the host response have received considerable attention, and herbal products are suggested as adjunctive agents in periodontal disease treatment. Objective This study aimed to demonstrate the effect of grape seed extract (GSE) on periodontitis. Material ...

Toll-like receptor agonists Porphyromonas gingivalis LPS and CpG differentially regulate IL-10 competency and frequencies of mouse B10 cells

J. appl. oral sci; 25 (1), 2017
Abstract IL-10 expressing regulatory B cells (B10) play a key role in immune system balance by limiting excessive inflammatory responses. Effects of toll-like receptor signaling and co-stimulatory molecules on B10 activity during innate and adaptive immune responses are not fully understood. Objective ...

Avaliação do controle da expressão gênica de citocinas pró inflamatórias mediado pela IL-10. Participação da IL-10 na modulação da resposta inflamatória exercida pela glutamina e na restrição alimentar

O desenvolvimento de uma resposta imune adequada é um processo extremamente importante para a manutenção da homeostase do organismo. Uma série de processos são desencadeados a partir do primeiro contato com micro-organismos patógenos até a efetivação da resposta imune de memória. Todos esses pr...

Continuous blood purification treatment for endotoxin-induced acute respiratory distress syndrome

Braz. j. med. biol. res; 50 (2), 2017
This study aimed to explore the effects of continuous blood purification (CBP) treatment in pigs affected with acute respiratory distress syndrome (ARDS). A total of 12 healthy male pigs, weighing 12±1.8 kg, were randomly and equally assigned to the control and experimental groups. The ARDS pig model wa...

IL-6 and IL-10 gene polymorphisms in patients with aggressive periodontitis: effects on GCF, serum and clinic parameters

Abstract Genetic variations observed in cytokines affect periodontitis susceptibility. The aim of this study was to investigate interleukin(IL)-6(-174) and IL-10(-597) gene polymorphisms in generalized aggressive periodontitis (GAgP) patients. Also, we aimed to evaluate the effects of IL-6 and IL-10 gene...

Metabotropic glutamate receptor 5 may be involved in macrophage plasticity

Biol. Res; 50 (), 2017
Abstract Background Macrophages are a functionally heterogeneous cell population and depending on microenvironments they polarize in two main groups: M1 and M2. Glutamic acid and glutamate receptors may participate in the regulation of macrophage plasticity. To investigate the role of glutamatergic sys...

Effect of lectin (ScLL) on fibroblasts stimulated with LPS - an in vitro study

Braz. oral res. (Online); 30 (1), 2016
Abstract: The lectin (ScLL) extracted from the Synadenium carinatum plant has been evaluated as an immunomodulator in diseases such as asthma, neosporosis and leishmaniasis. However, it has not yet been evaluated in the oral cavity. This study evaluated the effect of ScLL on viability, proliferation and ...

Immune enhancement activities of silk lutein extract from Bombyx mori cocoons

Biol. Res; 47 (), 2014
BACKGROUND: Declining immune function poses an important clinical challenge worldwide and supplementation with natural products that possessing immune enhancing properties is a promising approach for preventing or delaying immune function decline. Cocoons from yellow silkworms are a significant source of...

Estudo da resposta imune celular em pacientes com cromoblastomicose

A cromoblastomicose é uma micose crônica que causa lesões granulomatosas e supurativas que atingem a pele e o tecido subcutâneo. Micose cosmopolita e freqüentemente observada no Brasil. As lesões aumentam progressivamente e posteriormente podem desenvolver um processo crônico e que geralmente não...
