IL-17 and IL-22 are typical cytokines produced by the Th17 T cell subset, but it is unclear if Th17 cytokines can be produced by other cell types. We demonstrate that IL-10-deficient and IL-10R-deficient macrophages stimulated with lipopolysaccharide produce high levels of IL-17 and IL-22. Addition of exogenous IL-10 to IL-10-deficient macrophages abolished(More)
BACKGROUND & AIMS In food allergic individuals, exposure to food allergens by the oral route can trigger immediate (within minutes) local hypersensitivity reactions in the intestine followed by a late-phase inflammatory response. Previous work has shown that CD23 is constitutively expressed by human intestinal epithelial cells and mediates the uptake of(More)
Inflammation has a key role in diabetic nephropathy (DN) progression. Pentosan polysulfate (PPS) has been shown to decreases interstitial inflammation and glomerulosclerosis in 5/6 nephrectomized rats. Since PPS has an excellent long-term safety profile in interstitial cystitis treatment, and we recently found that old diabetic C57B6 mice develop DN(More)
Interleukin (IL)-23, a new member of the IL-12 family, plays a central role in the Th17 immune response and in autoimmune diseases. It is clear that activated macrophages and dendritic cells produce IL-23, but the molecular mechanisms whereby inflammatory signals stimulate IL-23 expression are not fully understood. We demonstrate that induction of IL-23 p19(More)
Recent studies showed that the activation of toll-like receptor 4 (TLR4) on dorsal root ganglion (DRG) neurons might underlie neuropathic and inflammatory pain states. This study was undertaken to investigate the effects of wogonin, a flavonoid with potent anti-inflammatory properties on the inflammatory reaction and TLR4 dependent pathways in(More)
Glucocorticoids stimulate foetal surfactant synthesis. Therefore, they are used in impending pre-term birth. One mechanism of action on surfactant synthesis is through the induction of neuregulin (NRG) secretion by foetal lung fibroblasts. The direct effects on signalling pathways, and specifically on erbB receptors in foetal type II cell surfactant(More)
