Fibroblasts are important to host defence and immunity, can also as initiators of inflammation as well. As the endogenous "braking signal", Lipoxins can regulate anti-inflammation and the resolution of inflammation. We investigated the effect of lipoxinA(4) on the expression of cyclooxygenase-2 in lipopolysaccharide-stimulated lung fibroblasts. We(More)
Fibroblasts, far from being merely bystander cells, are known to play a specific role in inflammation resolution after an acute injury. As the endogenous "braking signal," resolvins possess potent anti-inflammatory and pro-resolution actions. We demonstrated that the expression of COX-2 protein was significantly peaked initially at 6 hours but then also at(More)
RATIONALE Vitamin D deficiency has been implicated as a pathogenic factor in sepsis and intensive therapy unit mortality but has not been assessed as a risk factor for acute respiratory distress syndrome (ARDS). Causality of these associations has never been demonstrated. OBJECTIVES To determine if ARDS is associated with vitamin D deficiency in a(More)
Therapy that promotes epithelial repair whilst protecting against fibroproliferation is critical for restoring lung function in acute and chronic respiratory diseases. Primary human alveolar type II cells were used to model the effects of lipoxin A4in vitro upon wound repair, proliferation, apoptosis and transdifferention. Effects of lipoxin A4 upon primary(More)
Acute and chronic inflammatory lung diseases are often associated with epithelial cell injury/loss and fibroproliferative responses. ResolvinD1 (RvD1) is biosynthesized during the resolution phase of inflammatory response and exerts potent anti-inflammatory and promotes resolution of inflammatory lung diseases. The aim of this study was to investigate(More)
