To suppress virus multiplication, infected macrophages produce NO. However, it remains unclear how infecting viruses then overcome NO challenge. In the present study, we report the effects of accessory protein C from Sendai virus (SeV), a prototyp...
The effect of TGF-β1 on CpG DNA-induced type I IFN production was examined by reconstituting a series of signaling molecules in TLR 3 signaling. TGF-β1 inhibited CpG DNA-induced IFN-α4 productivity in HeLa cells. Transfection of IFN regulatory fac...
Here we report that LPS induces osteoclast (OC) formation in murine RAW 264.7 macrophage cells in RPMI-1640 medium but not in α-minimum essential medium (α-MEM) as the original culture medium. LPS-induced OC formation in both media was examined to...

The effect of LPS on the production of vascular endothelial growth factor (VEGF) was examined using RAW 264.7 macrophage cells. LPS induced VEGF production in RAW 264.7 cells and mouse peritoneal cells. LPS induced VEGF production via the expressi...

The inhibitory effect of valproic acid (VPA) on lipopolysaccharide (LPS)-induced inflammatory response was studied by using mouse RAW 264.7 macrophage-like cells. VPA pretreatment attenuated LPS-induced phosphorylation of phosphatidylinositol 3-ki...
The effect of lipopolysaccharide (LPS) on valproic acid (VPA)-induced cell death was examined by using mouse RAW 264.7 macrophage cells. LPS inhibited the activation of caspase 3 and poly (ADP-ribose) polymerase and prevented VPA-induced apoptosis...

A toll-like receptor 4 (TLR-4) ligand, lipopolysaccharide (LPS) not only activates expression and secretion of inflammatory cytokines, but it also often shows toxicity in monocytes. Whether an oncogenic protein, β-catenin, is positively involved i...
The LPS-mediated lethality of NC/Nga mice, having fewer NKT cells, was examined by using d-galactosamine (d-GalN)-sensitization. The NC/Nga mice were not killed by a simultaneous administration of d-GalN and LPS whereas all C57BL/6 (B6) control mi...
Thalidomide is known as an anti-angiogenic, anti-tumor, and anti-proliferative agent, widely used in the treatment of some immunological disorders and cancers. The effect of thalidomide on interferon (IFN)-gamma induced nitric oxide (NO) productio...
