Combining in vivo and in vitro approaches to better understand host-pathogen nutritional interactions. [PDF]
J Anim EcolThis is one of the first studies that use a combination of in vitro and in vivo approaches to tease apart the importance of the ‘top‐down’ and ‘bottom‐up’ effects of host nutrition in determining the outcome of host‐pathogen interactions. Abstract Nutrition often shapes the outcome of host–parasite interactions, however understanding the mechanisms by ...

The regulation of bacterial two‐partner secretion systems
Molecular Microbiology, Volume 120, Issue 2, Page 159-177, August 2023., 2023 Two‐partner secretion (TPS) systems play critical roles in bacterial pathogenesis by allowing the secretion of effector proteins such as cytolysins and adhesins. Here, we explore the diverse regulatory mechanisms that govern TPS system expression, including environmental stimuli, two‐component systems, quorum sensing, and global regulators, providing ...
