Mycobacterium tuberculosis Toxin CpnT Is an ESX-5 Substrate and Requires Three Type VII Secretion Systems for Intracellular Secretion

open access: yesmBio, 2021
CpnT, a NAD + glycohydrolase, is the only known toxin that is secreted by Mycobacterium tuberculosis . CpnT is composed of two domains; the C-terminal domain is the toxin, whereas the N-terminal domain is required for secretion.

Three small partner proteins facilitate the type VII-dependent secretion of an antibacterial nuclease

open access: yesmBio, 2023
The type VIIb secretion system (T7SSb) is a multisubunit protein export machine found in Gram-positive Bacillota which plays a key role in interbacterial competition.

Bacterial control of pores induced by the Type Three Secretion System: Mind the gap

open access: yesFrontiers in Immunology, 2016
Type Three secretion Systems (T3SSs) are specialized secretion apparatus involved in the virulence of many Gram-negative pathogens, enabling the injection of bacterial type III effectors into host cells. The T3SS-dependent injection of effectors requires

Comparative Genomics of Aeromonas hydrophila Secretion Systems and Mutational Analysis of hcp1 and vgrG1 Genes From T6SS

open access: yesFrontiers in Microbiology, 2019
Virulent Aeromonas hydrophila causes severe motile Aeromonas septicemia in warmwater fishes. In recent years, channel catfish farming in the U.S.A. and carp farming in China have been affected by virulent A.

Analysis of effectors of the Salmonella Typhimurium SPI‐2 type three secretion system

open access: green, 2011
Salmonella enterica serovar Typhimurium (S. Typhimurium), an intracellular pathogen, causes gastroenteritis in humans and a systemic disease in mice. The ability of Salmonella to replicate inside host cells requires translocation of effector proteins across the vacuolar membrane, mediated by the Salmonella pathogenicity island‐2 (SPI‐2) type three ...

Yersinia pseudotuberculosis YopE prevents uptake by M cells and instigates M cell extrusion in human ileal enteroid-derived monolayers

open access: yesGut Microbes, 2021
Many pathogens use M cells to access the underlying Peyer’s patches and spread to systemic sites via the lymph as demonstrated by ligated loop murine intestinal models.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

An Extract Produced by Bacillus sp. BR3 Influences the Function of the GacS/GacA Two-Component System in Pseudomonas syringae pv. tomato DC3000

open access: yesFrontiers in Microbiology, 2019
The GacS/GacA two-component system is essential for virulence in many plant pathogenic bacteria, and thus represents a promising anti-virulence target.

Diversity of virulence phenotypes among type III secretion negative Pseudomonas aeruginosa clinical isolates. [PDF]

open access: yesPLoS ONE, 2014
Pseudomonas aeruginosa is a frequent cause of acute infections. The primary virulence factor that has been linked to clinical disease is the type III secretion system, a molecular syringe that delivers effector proteins directly into host cells.
