Secretory leucoprotease inhibitor impairs Toll-like receptor 2- and 4-mediated responses in monocytic cells.

چکیده
Secretory leucoprotease inhibitor (SLPI) is an anti-inflammatory antiprotease which can inhibit lipopolysaccharide-induced NF-kappaB activation. We examined its ability to inhibit NF-kappaB activation induced by lipoteichoic acid and investigated the effects of oxidation or complex formation with neutrophil elastase on SLPI's anti-inflammatory properties in U937 myelomonocytic cells and macrophages.

Female and male reproductive tracts are of interest sites to study of immune system because they encounter specific infections such as those are sexually transmitted. Furthermore, female reproductive tract is in close contact with allogenic sperms and transmitted microorganisms during intercourse and semi allogenic fetus during pregnancy. In mammals, there are two types of immune responses, the...

In the development of neuroinflammatory diseases, alterations of the blood brain barrier (BBB) represent key events. The integrity of the BBB is partially maintained by endothelia cells (ECs), since they actively limit the transmigration of immune cells. However, the factors that cause endothelial cells to develop an immune cell-permissive phenotype are poorly understood. In general, it has bee...

Secretory leucoprotease inhibitor (SLPI) is a nonglycosylated protein produced by epithelial cells. In addition to its antiprotease activity, SLPI has been shown to exhibit antiinflammatory properties, including down-regulation of tumor necrosis factor alpha expression by lipopolysaccharide (LPS) in macrophages and inhibition of nuclear factor (NF)-kappaB activation in a rat model of acute lung...

Background & Objectives: Interaction of cytomegalovirus glycoprotein B with toll-like receptors of dendritic cells leads to early signaling and innate immune responses. The aim of this study is to evaluate the effects of cytomegalovirus glycoprotein B on the maturation and function of monocyte-derived dendritic cells in treated groups in comparison with control groups. Materials & Methods: Bloo...

TLR6 forms a heterodimer with TLR2 and TLR4. While proinflammatory roles of TLR2 and TLR4 are well documented, the role of TLR6 in inflammation is poorly understood. In order to understand mechanisms of action of TLR6 in inflammatory responses, we investigated the effects of FSL-1, the TLR6 ligand, on expression of chemokine CCL2 and cytokine IL-1β and determined cellular factors involved in FS...
