Abstract:
The emergence of antibiotic resistance coupled with the lack of investment by pharmaceutical companies necessitates a new look at how we tackle bacterial infections. An intriguing tactic is the interruption of bacterial communication systems. This non-biocidal approach would circumvent the evolutionary pressure on bacteria to mutate and develop resistance. In many pathogenic microorganisms, communication systems, collectively termed quorum sensing (QS), have been observed to control a number of bacterial behaviours including expression of virulence factors and the development of biofilms. QS signalling molecules and their biomimetics, therefore, represent a rational target for the disruption of cooperative behaviour and thus the development of novel antimicrobial strategies. Herein we review recent developments towards the interference of Pseudomonas aeruginosa QS using signalling molecules and their mimetics.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
