Abstract:

Despite the success of modern medicine in treating infections, infectious diseases remain a major source of morbidity and mortality worldwide. The evolution of antibiotic resistant strains of bacteria means that new innovations in therapeutics must be pursued to combat this emerging threat. A novel approach is to utilize the anti-infective properties of endogenous host defense peptides by creating smaller synthetic peptides with enhanced protective activities. Some of these peptides directly kill bacteria and many display varied immunomodulatory activities, enhancing the host innate immune res

Abstract:

Nous avons étudié des phages infectant Pseudomonas aeruginosa pour développer des stratégies antibactériennes. Nous avons d’abord étudié les mécanismes des stratégies virales détournant les fonctions bactériennes, et découvert que l’expression du gène phagique gp92 altère la morphologie bactérienne, la motilité et le protéome cellulaire, sans affecter la croissance. Gp92 altère également la réponse au stress membranaire médiée par AlgU, via son interaction avec MucA. Cette perturbation pourrait aider le phage à contrôler la lyse. Enfin, l'expression de gp92 augmente la sensibilité de P. aerugi

Therefore, the inhibition of tyrosinase activity will decrease the transformation to control the hyperpigmentation of skin. That is to say, the hyperpigmentation can be improved by inhibiting the oxidation of tyrosine. Current cosmetics that applied the whitening mechanisms are chemical compounds in the majority, and this study is based on the natural Chinese herb to investigate the whitening effect.

Therefore, inhibiting the growth or enzymatic activities of histamine producing bacteria (HPB) is a critical procedure to prevent histamine poisoning.

However, over the past decades, decreasing effectiveness of conventional antibiotics has caused serious problems because of the rapid emergence of multidrug-resistant (MDR) pathogens. Various researches indicated that antimicrobial peptides (AMPs) have potential to serve as an alternative to antibiotics owing to rapid killing action and high selective toxicity.

To combat these infections novel antibiotic agents are required.
