Abstract
The emergence and propagation of bacteria resistant to antimicrobial drugs is a serious public health threat worldwide. The current antibacterial arsenal is becoming obsolete, and the pace of drug development is decreasing, highlighting the importance of investment in alternative approaches to treat or prevent infections caused by antimicrobial-resistant bacteria. A significant mechanism of antimicrobial resistance employed by Gram-negative bacteria is the overexpression of efflux pumps that can extrude several compounds from the bacteria, including antimicrobials. The overexpression of efflux pump proteins has been detected in several multidrug-resistant Gram-negative bacteria, drawing attention to these proteins as potential targets against these pathogens. This review will focus on the role of outer membrane proteins from efflux pumps as potential vaccine candidates against clinically relevant multidrug-resistant Gram-negative bacteria, discussing advantages and pitfalls. Additionally, we will explore the relevance of efflux pump outer membrane protein diversity and the possible impact of vaccination on microbiota.
期刊介绍:
JLB is a peer-reviewed, academic journal published by the Society for Leukocyte Biology for its members and the community of immunobiologists. The journal publishes papers devoted to the exploration of the cellular and molecular biology of granulocytes, mononuclear phagocytes, lymphocytes, NK cells, and other cells involved in host physiology and defense/resistance against disease. Since all cells in the body can directly or indirectly contribute to the maintenance of the integrity of the organism and restoration of homeostasis through repair, JLB also considers articles involving epithelial, endothelial, fibroblastic, neural, and other somatic cell types participating in host defense. Studies covering pathophysiology, cell development, differentiation and trafficking; fundamental, translational and clinical immunology, inflammation, extracellular mediators and effector molecules; receptors, signal transduction and genes are considered relevant. Research articles and reviews that provide a novel understanding in any of these fields are given priority as well as technical advances related to leukocyte research methods.
