Toll-like receptor 2 activation primes and upregulates osteoclastogenesis via lox-1

Correlation between Salivary Toll Like Receptor-2 Concentration and Early Childhood Caries

Background: Early childhood caries (ECC) is a common health problem in the developing countries. Basic knowledge about the etiology and pathogenesis of ECC plays an important role in its prevention. Objective: To determine the relationship between salivary TLR-2 concentration and early childhood caries formation Methods: Twenty-Eight children with ages ranging from 36 to 71 months (15 in ECC gr...

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...

Angiotensin II upregulates toll-like receptor 4 on mesangial cells.

Angiotensin II (AngII) mediates proinflammatory properties by activating NF-kappaB transcription factor nuclear translocation and inducing the expression of chemokines. For examination of whether AngII modulates the expression of Toll-like receptor 4 (TLR4), a key element of the innate immune system that senses LPS, mouse mesangial cells (MMC) were treated with AngII. AngII upregulated TLR4 mRN...

Toll-like receptor 2 mediates apolipoprotein CIII-induced monocyte activation.

Apolipoprotein (apo)CIII predicts risk for coronary heart disease. We recently reported that apoCIII directly activates human monocytes. Recent evidence indicates that toll-like receptor (TLR)2 can contribute to atherogenesis through transduction of inflammatory signals. Here, we tested the hypothesis that apoCIII activates human monocytoid THP-1 cells through TLR2. ApoCIII induced the associat...
