Obesity becomes pandemic, predisposing these individuals to great risk for lung injury. In this review, we focused on the anti-inflammatories and addressed the following aspects: adipocytokines and obesity, inflammation and other mechanisms, adipocytokines and lung injury in obesity bridged by inflammation, and potential therapeutic targets. To sum up, the majority of evidence supported that ad...

High mobility group box 1 (HMGB1) is a novel late mediator of inflammatory responses that contributes to endotoxin-induced acute lung injury and sepsis-associated lethality. Although acute lung injury is a frequent complication of severe blood loss, the contribution of HMGB1 to organ system dysfunction in this setting has not been investigated. In this study, HMGB1 was detected in pulmonary end...

Urokinase plasminogen activator (uPA) plays a major role in fibrinolytic processes and also can potentiate LPS-induced neutrophil activation through interactions with its kringle domain (KD). To investigate the role of the uPA KD in modulating acute inflammatory processes in vivo, we cloned and then developed Abs to the murine uPA KD. Increased pulmonary expression of uPA and the uPA KD was pre...

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS), an illness characterized by life-threatening vascular leak, is a significant cause of morbidity and mortality in critically ill patients. Recent preclinical studies and clinical observations have suggested a potential role for the chemotherapeutic agent imatinib in restoring vascular integrity. Our prior work demonstrates differe...

BACKGROUND Few data are available on the role of neutrophil elastase (NE) and nuclear factor-κB (NF-κB) in the course of seawater drowning-induced acute lung injury (SWD-ALI), and there is no evidence on the value of giving urinary trypsin inhibitor (UTI) in the case of SWD-ALI. OBJECTIVE To investigate the role of NF-κB and NE in the pathogenesis of SWD-ALI and whether UTI treatment can atte...

The purpose of this study was to examine the effects of growth hormone (GH) on nuclear factor kappa B (NF-kappaB) activation and organ injury induced by lipopolysaccharide (LPS) in rats. Male Wistar rats were divided into 6 groups treated with saline, LPS (5 mg/kg), LPS plus GH (0.5, 1.0, 2.0 mg/kg), or GH (2.0 mg/kg) alone for 2 or 4 hr. NF-kappaB activity and I-kappaB level in lung, lung accu...

background: acute kidney injury (aki) has been recognized as one of the most complex clinical complications in modern medicine, and ischemia/reperfusion (i/r) injury is well-known as a main reason of aki. in addition, aki leads to important systemic consequences such as acute lung injury. this study was designed to investigate the role of erythropoietin (epo) on kidney function makers and tissu...

Panton-Valentine leukocidin (PVL) is a cytotoxin secreted by Staphylococcus aureus and associated with severe necrotizing infections. PVL targets polymorphonuclear leukocytes, especially neutrophils, which are the first line of defense against infections. Although PVL can induce neutrophil death by necrosis or apoptosis, the specific inflammatory responses of neutrophils to this toxin are uncle...

Regulation of pulmonary inflammation involves an intricate balance of both pro- and anti-inflammatory mediators. Acute lung injury can result from direct pulmonary insults that activate alveolar macrophages to respond with increased cytokine expression. Such cytokine gene expression is mediated in part via NF-kappaB. IL-10 has been previously identified as an important endogenous anti-inflammat...

Li-Fei-Xiao-Yan prescription (LFXY) has been clinically used in China to treat inflammatory and infectious diseases including inflammatory lung diseases. The present study was aimed at evaluating the potential therapeutic effects and potential mechanisms of LFXY in a murine model of lipopolysaccharide- (LPS-) induced acute lung injury (ALI). In this study, the mice were orally pretreated with L...
