Toll-like receptor (TLR) signaling induces a rapid reorganization of the actin cytoskeleton in cultured mouse dendritic cells (DC), leading to enhanced antigen endocytosis and a concomitant loss of filamentous actin-rich podosomes. We show that as podosomes are lost, TLR signaling induces prominent focal contacts and a transient reduction in DC migratory capacity in vitro. We further show that ...

PURPOSE Activation of Toll like receptors (TLRs) signaling has been implicated in promoting malignant cell invasion and metastatic potential. Previously we demonstrated that increased TLR-9 expression predicted poor survival in oral cancer patients. The objective of this study is to further investigate the roles and potential molecular mechanisms of TLR-9 signaling in human oral cancer cell inv...

Abstract Itaconate is a unique regulatory metabolite that induced upon toll-like receptor (TLR) stimulation in myeloid cells. Here, we demonstrate major inflammatory tolerance and cell death phenotypes associated with itaconate production activated macrophages. We show endogenous key regulator of the signal 2 NLRP3 inflammasome activation after long LPS priming which establishes to late activat...

Milk is a source of bioactive proteins with defensive properties great value for protecting the newborn. The activity bovine milk lactoferrin (LF) was investigated as an antibacterial agent in internalisation emergent pathogen Cronobacter sakazakii into Caco-2/TC7 cells, model human intestinal epithelium. effect LF on oxidative stress and expression Toll-like receptors (TLR) also investigated. ...

background: inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including crohn’s disease and ulcerative colitis (uc). il-17 has been the target of intensive research in autoimmune diseases. the influence of toll like receptor 4 (tlr-4) gene polymorphisms on il-17 production has also been revealed in uc patients and tissue inflammation in mice. objectives: to inve...

multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by a complex immune response. because of the complex nature of ms pathogenesis, a panel of biomarkers derived from different platforms will be required to reflect disease-related alterations. monitoring and evaluation of molecules associated with the pathogenesis of the disease would provide useful ...

Defensive systems against pathogens are responsible not only for survival or lifetime of an individual but also for the evolution of a species. Innate immunity is expected to be more important for invertebrates than mammals, given that adaptive immunity has not been acquired in the former. Toll-like receptors (TLRs) have been shown to play a crucial role in host defense of pathogenic microbes i...

Mammalian biological processes such as inflammation, involve regulation of hundreds of genes controlling onset and termination. MicroRNAs (miRNAs) can translationally repress target mRNAs and regulate innate immune responses. Our model system comprised primary human keratinocytes, which exhibited robust differences in inflammatory cytokine production (interleukin-6 and tumor necrosis factor-alp...

Toll-like receptors (TLRs) have been shown to play crucial role in the recognition of unicellular pathogens. We have shown the expression of three TLRs on tumor cells of human laryngeal carcinoma by means of immunohistochemistry. In the current study we searched presence of TLR1-10 on protein and molecular level in larynx carcinoma cell lines and the impact of respective TLR ligands on TLR expr...

This paper considers the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Our routing scheme is a combination of two protocols called Terminode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is activated when the destination is remote and uses location of the destination obtained either via location management or by location tracking. TLR acts when ...
