Publikováno v: PLoS Pathogens, Vol 18, Iss 3, p e1010213 (2022)
The general stress response (GSR) in Listeria monocytogenes plays a critical role in the survival of this pathogen in the host gastrointestinal tract. The GSR is regulated by the alternative sigma factor B (σB), whose role in protection against acid

The σB-Mediated General Stress Response of Listeria monocytogenes: Life and Death Decision Making in a Pathogen
Autor: Duarte N. Guerreiro, Talia Arcari, Conor P. O’Byrne
Publikováno v: Frontiers in Microbiology, Vol 11 (2020)
Sensing and responding to environmental cues is critical for the adaptability and success of the food-borne bacterial pathogen Listeria monocytogenes. A supramolecular multi-protein complex known as the stressosome, which acts as a stress sensing hub

The stressosome is required to transduce low pH signals leading to increased transcription of the amino acid-based acid tolerance mechanisms in Listeria monocytogenes
Autor: Duarte N. Guerreiro, Aoife Boyd, Conor P. O'Byrne
Publikováno v: Access Microbiology. 4
Increasing proton concentration in the environment represents a potentially lethal stress for single-celled microorganisms. To survive in an acidifying environment, the foodborne pathogen Listeria monocytogenes quickly activates the alternative sigma

In Vitro Evolution of Listeria monocytogenes Reveals Selective Pressure for Loss of SigB and AgrA Function at Different Incubation Temperatures

The alternative sigma factor B (σ(B)) contributes to the stress tolerance of the foodborne pathogen Listeria monocytogenes by upregulating the general stress response. We previously showed that σ(B) loss-of-function mutations arise frequently in st

Listeria monocytogenes requires the RsbX protein to prevent SigB-activation under non-stressed conditions
Autor: Hasan Tükenmez, Ana H. Oliveira, Duarte N. Guerreiro, Francisco García-del Portillo, Jörgen Johansson, Charlotte Dessaux, Teresa Tiensuu, Conor P. O'Byrne
Publikováno v: Journal of Bacteriology
The survival of microbial cells under changing environmental conditions requires an efficient reprogramming of transcription, often mediated by alternative sigma factors. The Gram-positive human pathogen Listeria monocytogenes senses and responds to
