the association between β2-adrenergic receptor (adrb2) -16arg/gly polymorphism (rs1042713) and chronic obstructive pulmonary disease (copd) risk has been investigated in many published studies. however, the results were inconclusive. a meta-analysis was performed to make a more precise estimation of the relationship.the pubmed, embase, isi web of science, the cochrane database of systematic rev...

Asthma and chronic obstructive pulmonary disease (COPD), chronic airway inflammatory diseases characterized by airflow limitation, have different etiologies and pathophysiologies. Asthma-COPD Overlap (ACO) has recently been used for patients with mixed asthma and COPD. The pathophysiological mechanisms of ACO have not been clearly understood due to the lack of an appropriate murine model. To in...

Animal models play an important role in the understanding of the pathogenesis of chronic obstructive pulmonary disease (COPD). The applicability of findings to human COPD depends upon several factors, including the disease model, and similarities in mouse structure and function between species. There are many examples in the literature of transgenic mice that have contributed to the understandi...

Chronic obstructive pulmonary disease (COPD) is a major health problem and cigarette smoke is the main risk factor for the development of COPD. The characteristic changes in airway morphology, inflammatory cell infiltration and mediator expression in COPD may result from direct effects of cigarette smoke (CS) on airway cells.CS causes lung damage through oxidative stress either by itself or due...

Viral infection is associated with approximately one-half of acute exacerbations of chronic obstructive pulmonary disease (COPD), which in turn, accelerate disease progression. In this study, we infected mice exposed to a combination of elastase and LPS, a constituent of cigarette smoke and a risk factor for development of COPD, with rhinovirus serotype 1B, and examined animals for viral persis...

enhanced immune cell trafficking into the central nervous system (cns) and disruption of the blood brain barrier are pathophysiological hallmarks of neuroinflammatory disorders like multiple sclerosis (ms) and its animal model, experimental autoimmune encephalomyelitis (eae). however, recent studies suggest that the coagulation and the contact-kinin system might also be involved in ms developme...

BACKGROUND Endothelial progenitor cells (EPCs) might play a protective role in COPD. The aim of this study was to investigate whether intratracheal allogeneic transplantation of bone-marrow-derived EPCs would attenuate the development of smoking-induced COPD in mice. METHODS Isolated mononuclear cells from the bone marrow of C57BL/6J mice were cultured in endothelial cell growth medium-2 for ...
