Apocynin is an effective and selective inhibitor of the neutrophil oxidative burst in vitro. Other neutrophil functions, tested in vitro, such as chemotaxis, exocytosis, phagocytosis and intracellular killing of bacteria are unaffected by apocynin. These properties make apocynin a potential
Oxidative stress is implicated in the pathogenesis of allergic asthma and remains an attractive target for the prevention of the disease. Herein, we investigated the anti-inflammatory effects of apocynin, a NADPH oxidase (NOX) inhibitor, in both in vitro and in vivo allergen-induced experimental
OBJECTIVE
This study evaluated the signalling coupled to the alpha1-adrenoceptor-induced stimulation of the Cl-/HCO3- exchanger in hypertension.
METHODS
The Na+ -independent HCO3- transport system activity was assayed as the initial rate of pHi recovery after an alkaline load (CO2/HCO3 removal) in
Central neuropathic pain is a common untreated symptom in progressive multiple sclerosis (PMS) and is associated with poor quality of life and interference with patients' daily activities. The neuroinflammation process and mitochondrial dysfunction in the PMS lesions generate reactive species. The
The present study tested the hypothesis that angiotensin II (Ang II)-induced oxidative stress and Ang II-stimulated Cl(-)/HCO(3)(-) exchanger are increased and related to the differential membrane Ang II type 1 (AT(1)) receptor and reduced nicotinamide-adenine dinucleotide phosphate oxidase
OBJECTIVE
To investigate the dysfunction of vascular smooth muscle in streptozotocin-induced diabetic rats.
METHODS
Rings without endothelium of femoral arteries were suspended in organ chambers for isometric tension recording. The production of oxygen-derived free radicals was measured with
Reactive oxygen species (ROS) are thought to be involved in the pathogenesis of multiple sclerosis (MS) and experimental allergic encephalomyelitis (EAE). In this study we showed that the phagocytosis of myelin by macrophages triggers the production of ROS. We also demonstrated that ROS play a
Exposure to environmental allergens is a major risk factor for asthma development. Allergens possess proteolytic activity that is capable of disrupting the airway epithelium. Although there is increasing evidence pointing to asthma as an epithelial disease, the underlying mechanism that drives
Chronic neuropathic pain is a common consequence of spinal cord injury (SCI), develops over time and negatively impacts quality of life, often leading to substance abuse and suicide. Recent evidence has demonstrated that reactive oxygen species (ROS) play a role in contributing to neuropathic pain
Despite intense investigation, the mechanisms of the different forms of trigeminal neuropathic pain remain substantially unidentified. The transient receptor potential ankyrin 1 channel (encoded by TRPA1) has been reported to contribute to allodynia or hyperalgesia in some neuropathic pain models,
