The phage-encoded PIT4 protein affects multiple two-component systems of Pseudomonas aeruginosa.

ABSTRACT:

Importance

More and more Pseudomonas aeruginosa isolates have become resistant to antibiotics like carbapenem. As a consequence, P. aeruginosa ranks in the top three of pathogens for which the development of novel antibiotics is the most crucial. The pathogen causes both acute and chronic infections, especially in patients who are the most vulnerable. Therefore, efforts are urgently needed to develop alternative therapies. One path explored in this article is the use of bacteriophages and, more specifically, phage-derived proteins. In this study, a phage-derived protein was studied that impacts key virulence factors of the pathogen via interaction with multiple histidine kinases of TCSs. The fundamental insights gained for this protein can therefore serve as inspiration for the development of an anti-virulence compound that targets the bacterial TCS.

Project description:There is a continuously expanding gap between predicted phage gene sequences and their corresponding functions, which has largely hampered the development of phage therapy. Previous studies reported several phage proteins that could interfere with the intracellular processes of the host to obtain efficient infection. But few phage proteins that protect host against phage infection have been identified and characterized in detail. Here, we isolate a phage, vB_Pae_QDWS, capable of infecting Pseudomonas aeruginosa PAO1 and report that its encoded Gp21 protein protects PAO1 against phage infection. Expression of Gp21 regulates bacterial quorum sensing with an inhibitory effect in low cell density and an activation effect in high cell density. By testing the type IV pilus (TFP)-mediated twitching motility and transmission electron microscopy analysis, Gp21 was found to decrease the pilus synthesis. Further, by constructing the TFP synthesis gene pilB mutant and performing adsorption and phage resistance assay, we demonstrated that the Gp21 protein could block phage infection via decreasing the TFP-mediated phage adsorption. Gp21 is a novel protein that inhibits phage efficacy against bacteria. The study deepens our understanding of phage-host interactions. IMPORTANCE The majority of the annotated phage genes are currently deposited as "hypothetical protein" with unknown function. Research has revealed that some phage proteins serve to inhibit or redirect the host intracellular processes for phage infection. Conversely, we report a phage encoded protein Gp21 that protects the host against phage infection. The pathways that Gp21 involved in antiphage defense in Pseudomonas aeruginosa PAO1 interfere with quorum sensing and decrease type IV pilus-mediated phage adsorption. Gp21 is a novel protein with a low sequence homology with other reported twitching inhibitory proteins. As a lytic phage-derived protein, Gp21 expression protects P. aeruginosa PAO1 from reinfection by phage vB_Pae_QDWS, which may explain the well-known pseudolysogeny caused by virulent phages. Our discoveries provide valuable new insight into phage-host evolutionary dynamics.

Project description:Pseudomonas aeruginosa is an opportunistic pathogen that can cause problematic infections at different sites throughout the human body. P. aeruginosa encodes a large suite of over 60 two-component signaling systems that enable cells to rapidly sense and respond to external signals. Previous work has shown that some of these sensory systems contribute to P. aeruginosa pathogenesis, but the virulence-associated processes and phenotypic traits that each of these systems controls are still largely unclear. To aid investigations of these sensory systems, we have generated deletion strains for each of 64 genes encoding histidine kinases and one histidine phosphotransferase in P. aeruginosa PA14. We carried out initial phenotypic characterizations of this collection by assaying these mutants for over a dozen virulence-associated traits, and we found that each of these phenotypes is regulated by multiple sensory systems. Our work highlights the usefulness of this collection for further studies of P. aeruginosa two-component signaling systems and provides insight into how these systems may contribute to P. aeruginosa infection.IMPORTANCEPseudomonas aeruginosa can grow and survive under a wide range of conditions, including as a human pathogen. As such, P. aeruginosa must be able to sense and respond to diverse signals and cues in its environment. This sensory capability is endowed in part by the hundreds of two-component signaling proteins encoded in the P. aeruginosa genome, but the precise roles of each remain poorly defined. To facilitate systematic study of the signaling repertoire of P. aeruginosa PA14, we generated a library of deletion strains, each lacking one of the 64 histidine kinases. By subjecting these strains to a battery of phenotypic assays, we confirmed the functions of many and unveiled roles for dozens of previously uncharacterized histidine kinases in controlling various traits, many of which are associated with P. aeruginosa virulence. Thus, this work provides new insight into the functions of two-component signaling proteins and provides a resource for future investigations.

Project description:In Pseudomonas aeruginosa, the complex multisensing regulatory networks RetS-GacS/GacA have been demonstrated to play key roles in controlling the switch between planktonic and sessile lifestyles. However, whether this multisensing system is involved in the regulation of phage infection has not been investigated. Here, we provide a link between the sensors RetS/GacS and infection of phages vB_Pae_QDWS and vB_Pae_W3. Our data suggest that the sensors kinases RetS and GacS in Pseudomonas aeruginosa play opposite regulatory functions on phage infection. Mutation in retS increased phage resistance. Cellular levels of RsmY and RsmZ increased in PaΔretS and were positively correlated with phage resistance. Further analysis demonstrated that RetS regulated phage infection by affecting the type IV pilus (T4P)-mediated adsorption. The regulation of RetS on phage infection depends on the GacS/GacA two-component system and is likely a dynamic process in response to environmental signals. The findings offer additional support for the rapid emergence of phage resistance. IMPORTANCE Our knowledge on the molecular mechanisms behind bacterium-phage interactions remains limited. Our study reported that the complex multisensing regulatory networks RetS-GacS/GacA of Pseudomonas aeruginosa PAO1 play key roles in controlling phage infection. The main observation was that the mutation in RetS could result in increased phage resistance by reducing the type IV pilus-mediated phage adsorption. The bacterial defense strategy is generally applicable to various phages since many P. aeruginosa phages can use type IV pilus as their receptors. The results also suggest that the phage infection is likely to be regulated dynamically, which depends on the environmental stimuli. Reduction of the signals that RetS favors would increase phage resistance. Our study is particularly remarkable for uncovering a signal transduction system that was involved in phage infection, which may help in filling some knowledge gaps in this field.
