The expression of TLR2 and TLR4 in the kidneys and heart of mice infected with Acanthamoeba spp.

Parasites & Vectors, 2020
Background Acanthamoeba spp. are cosmopolitan protozoans that cause infections in the brain, as well as extracerebral infections in the cornea, lungs and skin.

Chicken Toll-like Receptor 3 Recognizes Its Cognate Ligand When Ectopically Expressed in Human Cells [PDF]

, 2007
Recognition of pathogens by toll-like receptors (TLRs) causes activation of signaling cascades that trigger cytokine secretion and, ultimately, innate immunity.

Polymorphisms of toll-like receptor 2 and 4 genes in Chagas disease

Memorias do Instituto Oswaldo Cruz, 2008
The aim of this study was to test the possible implication of toll-like receptor 2 (TLR2) and TLR4 gene polymorphisms in determining the susceptibility to Chagas' disease. Genotypes were determined by polymerase chain reaction-restriction fragment length

Human Toll-like Receptor 2 Confers Responsiveness to Bacterial Lipopolysaccharide

Journal of Experimental Medicine, 1998
Bacterial lipopolysaccharide (LPS) induces activation of the transcription factor nuclear factor κB (NF-κB) in host cells upon infection. LPS binds to the glycosylphosphatidylinositol (GPI)- anchored membrane protein CD14, which lacks an intracellular ...

Modulation of Toll-like receptor activity by leukocyte Ig-like receptors and their effects during bacterial infection. [PDF]

, 2010
Toll-like receptors (TLRs) are a potent trigger for inflammatory immune responses. Without tight regulation their activation could lead to pathology, so it is imperative to extend our understanding of the regulatory mechanisms that govern TLR expression ...

Evaluation of toll-like receptors 2 and 4 polymorphism and intestinal microbiota in children with food allergies

The Turkish Journal of Pediatrics, 2023
Background. Mutual regulation between immune system and gut microbiota is achieved through several mechanisms including the engagement of toll-like receptors (TLRs) which is expressed on numerous cell types.

Modulation of atherosclerosis in mice by Toll-like receptor 2 [PDF]

Journal of Clinical Investigation, 2005
Epidemiologic evidence has established a relationship between microbial infection and atherosclerosis. Mammalian TLRs provide clues on the mechanism of this inflammatory cascade. TLR2 has a large ligand repertoire that includes bacterial-derived exogenous and possibly host-derived endogenous ligands.

Expression of Toll-like receptor (TLR) 2 and TLR4 in the livers of mice infected by Clonorchis sinensis

Journal of Infection in Developing Countries, 2015
Introduction: Clonorchis sinensis is one of the most important foodborne pathogens in humans, and can cause biliary diseases such as gallstones, cholecystitis, cholangitis, and cholangiocarcinoma.

Mechanisms for the activation of Toll-like receptor 2/4 by saturated fatty acids and inhibition by docosahexaenoic acid

European Journal of Pharmacology, 2016
Saturated fatty acids can activate Toll-like receptor 2 (TLR2) and TLR4 but polyunsaturated fatty acids, particularly docosahexaenoic acid (DHA) inhibit the activation.

Toll-like receptor signaling and SIGIRR in renal fibrosis upon unilateral ureteral obstruction. [PDF]

, 2011
Innate immune activation via IL-1R or Toll-like receptors (TLR) contibutes to acute kidney injury but its role in tissue remodeling during chronic kidney disease is unclear.
