Abstract

The rise of antibiotic resistance is an increasingly important threat, particularly for infections caused by Pseudomonas aeruginosa. One of the primary mechanisms driving this resistance is the overexpression of efflux pump systems, which enable resistance to a wide range of drugs with different constitutional features. The RND family of efflux pumps, including MexAB-OprM, MexCD-OprJ, MexEF-OprN, and MexXY-OprM, represent an important set of efflux systems in P.aeruginosa, with a broad range of drug specificities. MexAB-OprM was the first efflux pump found to target multiple classes of drugs. MexCD-OprJ exhibits a high degree of sequence similarity to MexABOprM, and has also been shown to extrude a variety of antimicrobial agents. The other efflux pump, MexEF-OprN is able to export. The contributions of the remaining RND efflux pumps to resistance, and the mechanisms governing their expression, have yet to be fully elucidated. This review focuses on details of efflux pump systems in P.aeruginosa resistance mechanisms

Özet

Pseudomonas aeruginosa kaynaklı infeksiyonların tedavisinde antibiyotik direnci her geçen gün önemi artan bir konu olup yapısal olarak farklı birçok antibiyotiğe kazanılmış dirençle ilişkili atım pompa sistemleri dikkat çekicidir. P.aeruginosa atım pompa sistemleri arasında önemli bir yeri olan RND ailesi; MexAB-OprM, MexCD-OprJ, MexEFOprN ve MexXY-OprM gibi atım pompa sistemlerini içermektedir. İlk tanımlanan atım pompası olan MexAB-OprM farklı sınıflardaki ilaçların hücreden dışarı atılmasını sağlamaktadır. MexAB-OprM'ye yüksek derecede benzerliği olduğu sekans çalışmalarıyla gösterilen MexCD-OprJ pompasının da çeşitli antimikrobiyal ajanların atımında rol oynadığı gösterilmiştir. Benzer şekilde MexEF-OprN de dışarı atımı destekleyen bir diğer pompa sistemidir. Diğer RND atım pompalarının dirence katkıları ve ekspresyonlarını kontrol eden faktörler henüz tanımlanmaya başlanmıştır. Bu derlemede P.aeruginosa antibiyotik direnç mekanizmalarından atım pompa sistemleri hakkında mevcut durum ayrıntılı olarak incelenecektir.
