Cholesterol‐dependent cytolysins: The outstanding questions
Sign Up to like & getrecommendations! Published in 2022 at "IUBMB Life"
DOI: 10.1002/iub.2661
Abstract: The cholesterol‐dependent cytolysins (CDCs) are a major family of bacterial pore‐forming proteins secreted as virulence factors by Gram‐positive bacterial species. CDCs are produced as soluble, monomeric proteins that bind specifically to cholesterol‐rich membranes, where they… read more here.

DOI: 10.1038/s41423-021-00827-0
Abstract: Cholesterol is a critical lipid for all mammalian cells, ensuring proper membrane integrity, fluidity, and biochemical function. Accumulating evidence indicates that macrophages rapidly and profoundly reprogram their cholesterol metabolism in response to activation signals to… read more here.

DOI: 10.1038/s41598-017-14002-x
Abstract: Cholesterol distribution in the cell is maintained by both vesicular and non-vesicular sterol transport. Non-vesicular transport is mediated by the interaction of membrane-embedded cholesterol and water-soluble proteins. Small changes to the lipid composition of the… read more here.

DOI: 10.1099/mic.0.001279
Abstract: One-third of the world's population is estimated to be latently infected with Mycobacterium tuberculosis. This reservoir of bacteria is largely resistant to antimicrobial treatment that often only targets actively replicating mycobacteria, with current treatment for… read more here.

DOI: 10.3389/fmicb.2021.691731
Abstract: Treponema pallidum subspecies pallidum, the causative agent of syphilis, traverses the vascular endothelium to gain access to underlying tissue sites. Herein, we investigate the mechanisms associated with T. pallidum traversal of endothelial barriers. Immunofluorescence microscopy… read more here.

DOI: 10.3390/toxins15010004
Abstract: The plasma membrane (PM) protects cells from extracellular threats and supports cellular homeostasis. Some pathogens produce pore-forming toxins (PFTs) that disrupt PM integrity by forming transmembrane pores. High PFT concentrations cause massive damage leading to… read more here.
