Acute lung injury is frequently associated with sepsis or blood loss and is characterized by a proinflammatory response and infiltration of activated neutrophils into the lungs. Hemorrhage or endotoxemia result in activation of cAMP response elementbinding protein (CREB) and NF-kB in lung neutrophils as well as increased expression of proinflammatory cytokines, such as TNF-a and macrophage-infl...
Bacterial genome is characterized by frequent unmethylated cytosine-phosphate-guanine (CpG) motifs. Deleterious effects can occur when synthetic oligodeoxynucleotides (ODN) with unmethylated CpG dinucleotides (CpG-ODN) are administered in a systemic fashion. We aimed to evaluate the effect of intratracheal CpG-ODN on lung inflammation and systemic inflammatory response. C57BL/6J mice received i...
The respiratory tract is innervated by irritant-responsive sensory nerves, which, on stimulation, release tachykinin neuropeptides in the lung. Tachykinins modulate inflammatory responses to injury by binding to tachykinin (neurokinin) receptors present on various pulmonary cell types. In the present study, the activation of the proinflammatory transcription factor NF-kappaB in lung epithelial ...
The NF-κB family of transcription factors is important for many cellular functions, in particular initiation and propagation of inflammatory and immune responses. However, recent data has suggested that different subunits of the NF-κB family can suppress the inflammatory response. NF-κB1, from the locus nfκb1, can inhibit transcription, acting as a brake to the recognised pro-inflammatory activ...
Veronicastrum axillare is a traditional medical plant in China which is widely used in folk medicine due to its versatile biological activities, especially for its anti-inflammatory effects. However, the detailed mechanism underlying this action is not clear. Here, we studied the protective effects of V. axillare against acute lung injury (ALI), and we further explored the pharmacological mecha...
The study aimed to observe the effects of inhaled hydrogen sulfide on smoke inhalation-induced acute lung injury in an animal model. In this study, male Sprague-Dawley (SD) rats were divided into intervention and control groups. The intervention group was divided into three subgroups: smoke group (n=6), smoke+H2S 3 h group (n=6), and smoke+H2S 6 h group (n=6). A control group (n=6) received tre...
Hemorrhage results in excessive production of superoxide that is associated with severe lung injury. We examined whether the superoxide dismutase (SOD) mimetic manganese(III) mesotetrakis (di-N-ethylimidazole) porphyrin (AEOL 10150) could attenuate this lung injury and whether extracellular (EC)-SOD-deficient mice would have increased hemorrhage-induced lung injury. Compared with wild-type mice...
OBJECTIVES Mesenchymal stem cells (MSCs) have shown an obvious protective effect on systemic inflammation. The purpose of this study is to assess the effect and possible mechanism of bone marrow MSCs (bmMSCs) on acute pancreatitis (AP). METHODS BmMSCs of SD rats were isolated and cultured in vitro. L-Arginine-induced acute pancreatitis was used as AP model in vivo. Pancreatic injury was asses...
Inflammatory responses are a major component of secondary injury and play a central role in mediating the pathogenesis of acute and chronic spinal cord injury (SCI). The nuclear factor-kappaB (NF-kappaB) family of transcription factors is required for the transcriptional activation of a variety of genes regulating inflammatory, proliferative, and cell death responses of cells. In this study we ...
RATIONALE Our study has shown that plasma levels of ghrelin, a stomach-derived peptide, are significantly reduced in sepsis, and that ghrelin administration improves organ blood flow via a nuclear factor (NF)-kappaB-dependent pathway. However, it remains unknown whether ghrelin has any protective effects on severe sepsis-induced acute lung injury (ALI) and, if so, whether inhibition of NF-kappa...
