The high rate of mortality in patients with sepsis results from an inappropriately amplified systemic inflammatory response to infection. Toll-like receptors (TLRs) are important for the activation of innate immunity against microbial pathogens. We demonstrate a critical role of TLR9 in the dysregulated immune response and death associated with sepsis. Compared with wild-type (WT) mice, TLR9(-/...

PURPOSE To determine the effects of silencing Toll-like receptor (TLR) 9 signaling in Pseudomonas aeruginosa keratitis. METHODS Corneal TLR9 mRNA levels were tested by RT-PCR in C57BL/6 (B6, susceptible) and BALB/c (resistant) mice and compared. The response of B6 mice to CpG DNA, which binds TLR9, was tested after subconjunctival injection of mice with control or CpG DNA; TLR9, IL-1beta, mac...

AIM To analyze the effect of TLR-9 (-1486 T>C) and TLR-9 (C>T) gene polymorphisms both at TLR-9 levels and together with their sepsis parameters. In this regard, the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used in order to detect TLR-9 gene polymorphisms, whereas the ELISA technique was used to analyze TLR-9 serum levels in 80 sepsis patients ...
