Research Article: ?-Glycyrrhetinic Acid Alleviates P. multocida-Induced Vascular Endothelial Inflammation by PARP-Mediated NF-?B and HMGB Signalling Suppression in PIEC Cells
Abstract:
Pasteurella multocida is a zoonotic pathogen with the ability to infect a wide range of hosts including humans as well as domestic, wild and companion animals., Infection with P. multocida is responsible for significant morbidity and mortality in humans and animals., The pathogen is one of the culprits causing major economic losses in the pig industry worldwide because of its persistently high prevalence: % prevalence with pneumonia or progressive atrophic rhinitis (PAR) between and in China, .% prevalence of , samples between and in China, .% prevalence of , isolated swine respiratory cases between and in the United States, .% prevalence between and in South Korea, .% prevalence between and in Korea. In clinically diseased pigs, most P. multocida strains are characterised as capsular type A and D, causing respiratory disorder in pigs, such as PAR, pneumonia, pleurisy and septicaemia.– The haemorrhagic pneumonia caused by P. multocida infection suggests severe injury to the vascular endothelial cells at the site of pathogenesis and is accompanied by increased vascular endothelial permeability. At present, clinical prevention and treatment of P. multocida infection are mainly based on the application of antimicrobials and vaccines,, which do not eliminate the vascular endothelial inflammation injury caused by P. multocida infection but also cause the development of drug resistance. In addition, antimicrobials, glucocorticoids or non-steroidal anti-inflammatory drugs often cause adverse effects such as bacterial endotoxin release, immune suppression or gastric ulcers. Therefore, elucidating the molecular mechanisms of vascular endothelial inflammation injury caused by P. multocida infection and developing adjuvant therapies or effective drugs to control inflammation P. multocida infection are of great scientific interest and application to reduce the harm of P. multocida infection.
