BACKGROUND High-tidal-volume mechanical ventilation used in patients with acute lung injury (ALI) can induce the release of inflammatory cytokines, as macrophage inflammatory protein-2 (MIP-2), recruitment of neutrophils, and disruption of alveolar epithelial and endothelial barriers. Induced pluripotent stem cells (iPSCs) have been shown to improve ALI in mice, but the mechanisms regulating th...
Hepatic ischemia and reperfusion cause local and remote organ injury. This injury culminates from an integrated cascade of proinflammatory cytokines, chemokines, and adhesion molecules, many of which are regulated by the transcription factor nuclear factor-kappaB (NF-kappaB). The anti-inflammatory cytokine interleukin-10 (IL-10) has been shown to have inhibitory effects on NF-kappaB. The object...
Objective(s): Obstructive sleep apnea (OSA) is confirmed to cause lesions in multiple organs, especially in the lung tissue. Tempol is an antioxidant that has been reported to restrain inflammation and oxidative stress, with its role in OSA-induced lung injury being unclear. This study aimed to investigate the beneficial effect of tempol on chronic intermittent hypoxia (IH)-induced lung injury....
BACKGROUND Oxidation plays an important role in acute lung injury. This study was conducted in order to elucidate the effect of repetitive post-treatment of N-acetylcysteine (NAC) in lipopolysaccaride (LPS)-induced acute lung injury (ALI) of rats. METHODS Six-week-old male Sprague-Dawley rats were divided into 4 groups. LPS (Escherichia coli 5 mg/kg) was administered intravenously via the tai...
Influenza viruses (IV) cause pneumonia in humans with progression to lung failure and fatal outcome. Dysregulated release of cytokines including type I interferons (IFNs) has been attributed a crucial role in immune-mediated pulmonary injury during severe IV infection. Using ex vivo and in vivo IV infection models, we demonstrate that alveolar macrophage (AM)-expressed IFN-β significantly contr...
Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) that causes COVID-19 could progress to acute respiratory distress syndrome (ARDS). The immune cells' migration in response to virus lead to cell death by releasing oxidizing free radicals. These oxidizing free radicals mediate NF-κB activation and induce transcription of cytokine-producing genes that eventually a cytokine storm ensues...
Lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1), a cell surface receptor expressed in endothelial cells, is known to mediate oxidized LDL-induced vascular inflammation and atherogenesis. Although the role of LOX-1 in vascular inflammation has been well established, its involvement in acute lung inflammation and injury remains unclear. In the present study, we examined the ...
Intestinal ischemia reperfusion (IR) injury is a critical problem, which can cause intestinal injury locally and acute lung injury (ALI) distally by inflammatory responses and oxidative stress. Toll-like receptor 4 (TLR4) is involved in innate immune and inflammatory responses. This study was to determine whether TLR4 mutant can attenuate intestinal and lung injuries after intestinal IR. Wild t...
BACKGROUND Although in vitro studies have determined that the activation of mitogen-activated protein (MAP) kinases is crucial to the activation of transcription factors and regulation of the production of proinflammatory mediators, the roles of c-Jun NH2-terminal kinase (JNK) and extracellular signal-regulated kinase (ERK) in acute lung injury have not been elucidated. METHODS Saline or lipo...
