25. Association between Toll-like receptor 4 Asp299Gly polymorphism and coronary heart disease susceptibility
Published data on the association between Toll-like receptor 4 (TLR4) Asp299Gly polymorphism and coronary heart disease (CHD) susceptibility are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. English-language studies were identified by searching PubMed and Embase databases (up to November 2016). All epid

26. Transcrição endometrial de receptores de padrões moleculares microbianos em vacas Gir e F1 Holandês x Gir após o parto
RESUMO Vacas Zebu e mestiças Holandês x Zebu apresentam baixas incidências de infecções uterinas quando comparadas às Holandesas. A resistência às infecções uterinas pode estar relacionada com a capacidade de reconhecimento dos microrganismos invasores. A transcrição endometrial de receptores de padrões moleculares microbianos tem sido investiga

27. Agaricus brasiliensis polysaccharides stimulate human monocytes to capture Candida albicans, express toll-like receptors 2 and 4, and produce pro-inflammatory cytokines
Abstract Background Agaricus brasiliensis is a medicinal mushroom with immunomodulatory and antitumor activities attributed to the β-glucans presented in the polysaccharide fraction of its fruiting body. Since β-glucans enhance cellular immunoresponsiveness, in this study we aimed to evaluate the effect of an acid-treated polysaccharide-rich fraction (ATF

28. Polymorphisms in genes TLR1, 2 and 4 are associated with differential cytokine and chemokine serum production in patients with leprosy
BACKGROUND Leprosy or hansen’s disease is a spectral disease whose clinical forms mostly depends on host’s immune and genetic factors. Different Toll-like receptors (TLR) variants have been described associated with leprosy, but with some lack of replication across different populations. OBJECTIVES To evaluate the role of polymorphisms in genes TLR1,

29. Upregulation of TLR4 mRNA Expression Levels in Broiler Chickens Under Acute Heat Stress
ABSTRACT Toll-like receptors (TLRs) are well-characterized in mice and rats, but little is known on their role in broiler chickens during acute heat stress (AHS). The aim of the present study was to estimate the change in TLR4 mRNA expression in the liver, kidney's pleen, heart, and small intestine of broiler chickens under AHS. A total of 240 healthy Arbor

30. A meta-analysis of TLR4 and TLR9 SNPs implicated in severe malaria
Abstract Toll-like receptors (TLRs) are critical mediators of the inflammatory response to malarial infection, and gene polymorphisms affecting TLR function may be partially responsible for inter-individual variation in disease manifestation. However, there are inconsistencies in the associations of common genetic variants of TLR4 (D299G) and TLR9 (T-1237C a

31. Bacillus Coagulans Enhance the Immune Function of the Intestinal Mucosa of Yellow Broilers
ABSTRACT This experiment was conducted to investigate the effects of Bacillus coagulans on the growth performance and immune functions of the intestinal mucosa of yellow broilers. Three hundred and sixty one-day-old yellow chicks were randomly allocated to four treatments groups with six replicates of 15 chicks each. The broilers were randomly subjected to o

32. Classical and alternative macrophages have impaired function during acute and chronic HIV-1 infection
Abstract Objectives: Three decades after HIV recognition and its association with AIDS development, many advances have emerged – especially related to prevention and treatment. Undoubtedly, the development of Highly Active Antiretroviral Therapy (HAART) dramatically changed the future of the syndrome that we know today. In the present study, we evaluate t

33. Osteogenic potential of periodontal ligament stem cells are unaffected after exposure to lipopolysaccharides
Abstract Periodontitis develops as a result of a continuous interaction between host cells and subgingival pathogenic bacteria. The periodontium has a limited capacity for regeneration, probably due to changes in periodontal ligament stem cells (PDLSCs) phenotype. The aim of this study was to evaluate the effects of lipopolysaccharides from Porphyromonas gin

34. Características clínicas e frequência de polimorfismos em TLR4 em pacientes brasileiros com espondilite anquilosante
RESUMO Objetivos: A imunidade inata está envolvida na fisiopatologia da espondilite anquilosante (EA), com a participação de bactérias gram-negativas, modulação do antígeno leucocitário humano (HLA) B27 e o envolvimento de receptores de reconhecimento de padrões, como os receptores Toll-like (TLR). O objetivo deste estudo foi investigar as caracter

35. TLR2 and TLR4 mediated host immune responses in major infectious diseases: a review
Abstract During the course of evolution, multicellular organisms have been orchestrated with an efficient and versatile immune system to counteract diverse group of pathogenic organisms. Pathogen recognition is considered as the most critical step behind eliciting adequate immune response during an infection. Hitherto Toll-like receptors (TLRs), especially t

36. Effect of LPS on the Viability and Proliferation of Human Oral and Esophageal Cancer Cell Lines
The esophagus and mouth tumors are very frequent malignancies worldwide. Lipopolysaccharides (LPS) are capable of regulating gene expression of pro-inflammatory cytokines by binding to toll-like receptor 4 (TLR4). Recent studies show that LPS can increase the migration ability of human esophageal cancer cell line HKESC-2 by increasing its adhesion properties
