Pulmonary fibrosis represents a leading cause of morbidity and mortality worldwide. Therapy induced lung fibrosis constitutes a pivotal dose-limiting side effect of radiotherapy and other anticancer agents. We aimed to develop objective criteria for assessment of fibrosis and discover pathophysiological and molecular correlates of lung fibrosis as a function of fractionated whole thoracic irradiation. Dose-response series of fractionated irradiation was utilized to develop a non-invasive and quantitative measure for the degree of fibrosis - the fibrosis index (FI)...

Pericyte coverage on the endothelial tubes leads to the formation of a mature and stable microvessel system, which is critical for brain repair after intracerebral hemorrhage (ICH). We report herein that thrombin promotes pericyte coverage by activating Tie2 and the downstream signaling pathway PI3K/Akt in a rat model of ICH. ICH was induced by injection of autologous blood with or without thrombin inhibitor hirudin. Rats were treated with thrombin alone or in combination with a Tie2 inhibitor. The expression of total- and phospho-Tie2, PI3K and phospho-Akt, blood perfusion, pericyte coverage, IgG extravasation, neuron survival and neurological deficits were evaluated by western blot, fluorescein-5-isothiocyanate-dextran staining, immunohistochemistry, Nissl staining and modified neurological severity scores respectively...

BACKGROUND: Neutrophil extracellular traps (NETs) play a crucial role in host defense, but excess and prolonged interaction of NETs with platelets can cause severe inflammation and host organ damage. Modification of histone H3 by citrullination is involved in in vitro NET formation. The phosphodiesterase III inhibitor, cilostazol (Ciz), which has a protective effect on liver sinusoidal endothelial cells and inhibits platelet aggregation, may prevent organ damage caused by excess NETosis...

Abnormal angiogenesis plays a major role in the development of early stage diabetic nephropathy. Vascular endothelial growth factor (VEGF) is a classical proangiogenic factor that regulates abnormal glomerular angiogenesis linked to glomerular hypertrophy in the early stage of diabetic nephropathy. Leucine-rich α -2-glycoprotein-1 (LRG1) was recently reported as a novel proangiogenic factor that is expressed in endothelial cells and promotes angiogenesis by modulating the transforming growth factor- β signaling pathway...

Stem cell therapy is one of the promising strategies for the treatment of ischemic heart disease. However, the clinical application of stem cells transplantation is limited by low cell engraftment in the infarcted myocardium. Taking advantage of pretargeting and bioorthogonal chemistry, we engineered a pretargeting and bioorthogonal chemistry (PTBC) system to capture endogenous circulating stem cells and target them to the injured heart for effective repair. Two bioorthogonal antibodies were i.v. administrated with a pretargeting interval (48 h)...

BACKGROUND: A complex inflammatory response mediates the systemic effects of burn shock. Disruption of the endothelial glycocalyx causes shedding of structural glycoproteins, primarily syndecan-1 (SDC-1), leading to endothelial dysfunction. These effects may be mitigated by resuscitative interventions. MATERIALS AND METHODS: Sprague-Dawley rats were used to create small, medium, and large burns and uninjured controls. Three different intravenous resuscitation protocols were applied within each group: Lactated Ringer's (LR) alone, LR plus fresh frozen plasma (FFP), or LR plus albumin...

BACKGROUND: Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease in which comprehensive inflammation-related cytokines are involved. These cytokines are commonly produced by immune cells and specific nonimmune cells including keratinocytes, endothelial cells and fibroblasts. This raises the question of whether fibroblasts in OLP lesions contribute to the inflammatory process upon inflammatory simulation. METHODS: Primary cultured Oral lichen-planus-associated fibroblasts (OLP AFs, n = 5) and normal buccal mucosal fibroblasts (NFs, n = 5) were examined by immunohistochemistry, Western blotting and reverse transcription-polymerase chain reactions (RT-PCR)...
