15 صفحه اولLentiviral vector-mediated delivery of lysophosphatidylcholine acyltransferase 1 attenuates airway inflammation in ovalbumin-induced allergic asthmatic mice.
BACKGROUND Lysophosphatidylcholine (LPC) is generated through the hydrolysis of phospha-tidylcholine (PC) by phospholipase A2 and is converted back to PC by lysophosphatidylcholine acyltransferase 1 (LPCAT1). Elevated levels of (LPC) are known to play a pathogenic role in the inflammatory injury of asthma. However, the role of LPCAT1 in asthma has not yet been reported. OBJECTIVE To determine...
متن کاملBronchoconstriction induced by increasing airway temperature in ovalbumin-sensitized rats: role of tachykinins.
This study was carried out to determine the effect of allergic inflammation on the airway response to increasing airway temperature. Our results showed the following: 1) In Brown-Norway rats actively sensitized by ovalbumin (Ova), isocapnic hyperventilation with humidified warm air (HWA) for 2 min raised tracheal temperature (Ttr) from 33.4 ± 0.6°C to 40.6 ± 0.1°C, which induced an immediate an...
متن کاملHypersensitivity of vagal pulmonary C-fibers induced by increasing airway temperature in ovalbumin-sensitized rats.
Our recent study has shown that hyperventilation of humidified warm air (HWA) triggered cough and reflex bronchoconstriction in patients with mild asthma. We suggested that a sensitizing effect on bronchopulmonary C-fibers by increasing airway temperature was involved, but direct evidence was lacking. This study was carried out to test the hypothesis that HWA enhances the pulmonary C-fiber sens...
متن کاملInfliximab alleviates inflammation and ex vivo airway hyperreactivity in asthmatic E3 rats.
Tumor necrosis factor-α (TNF-α) has been implicated in the pathogenesis of asthma, and neutralization of TNF-α is an effective therapy for inflammatory diseases. The present study tested the idea that a TNF-α antibody, infliximab, may be useful in the management of asthma. E3 rats were immunized with ovalbumin (OVA)/alum and received infliximab intra-peritoneally. Two weeks later, OVA-PBS was i...
