Pseudomonas aeruginosa flagella activate airway epithelial cells through asialoGM1 and toll-like receptor 2 as well as toll-like receptor 5.

The distribution of specific toll-like receptors and components of the signaling pathways activated by Pseudomonas aeruginosa flagella were studied in airway epithelial cells. Initially flagella bound to the apical surface of polarized epithelial cells, where they prominently colocalized with asialoGM1. By 4 h of exposure to flagella, toll-like receptor (TLR)5 expression was induced, mobilized ...

Toll Like Receptor 2 and 4 Expression in Peripheral Blood Mononuclear Cells of Multiple Sclerosis Patients

Background: Multiple sclerosis (MS) is a T cell mediated autoimmune disease with unknown etiology. Appropriate MS therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. Ligation of TLR-2 and TLR-4 stimulates the production of several cytokines leading to CNS autoimmunity and neurodegenerative diseases. Objective: To find a relationship between M...

Toll-like receptor expression and function in airway epithelial cells.

Toll-like receptors (TLRs) belong to a family of transmembrane proteins that can recognize and discriminate a diverse array of microbial antigens. Following their activation by specific ligands, TLRs initiate intracellular signaling cascades that culminate in the activation of transcription factors and ultimately lead to changes in pro-inflammatory gene expression. The TLR family constitutes an...

Bacterial fimbriae and their peptides activate human gingival epithelial cells through Toll-like receptor 2.

Gingival epithelial cells are a central component of the barrier between oral microflora and internal tissues. Host responses to periodontopathic bacteria and surface components containing fimbriae are thought to be important in the development and progression of periodontal diseases. To elucidate this mechanism, we established immortalized human gingival epithelial cells (HGEC) that were trans...

MicroRNAs activate natural killer cells through Toll-like receptor signaling.

MicroRNAs (miRNAs) bind to complementary sequences of target mRNAs, resulting in translational repression or target degradation and thus gene silencing. miRNAs are abundant in circulating blood, yet it is not known whether, as a class of regulatory molecules, they interact with human natural killer (NK) cells. Here we found that the treatment of human NK cells with several mature miRNAs in the ...
