Cellular cholesterol licenses Legionella pneumophila intracellular replication in macrophages
December 6, 2022
Host membranes are inherently critical for niche homeostasis of vacuolar pathogens such as Legionella. One membrane component that is often subverted by vacuolar bacteria is cholesterol. We provide experimental evidence that cellular cholesterol promotes L. pneumophila replication within a membrane bound organelle in infected macrophages.
A holobiont view on thrombosis: unravelling the microbiota’s influence on arterial thrombus growth
January 6, 2020
In this article, the authors comment on the study "The microbiota promotes arterial thrombosis in low-density lipoprotein receptor-deficient mice" by Kiouptsi et al. (mBio, 2019) that showed that commensal microbiota, intricately linked to host physiology, may influence cardiovascular disease, as shown by studies using germ-free atherosclerosis-prone mice to examine how microbial presence and diet affect arterial thrombosis and lesion development.
