Summary
Project Summary The proposed project focuses on our recent discovery that immunological production of the oxysterol 25- Hydroxycholesterol (25HC) potently inhibits the cellular dissemination of two globally important bacterial pathogens, Listeria monocytogenes and Shigella flexneri. The anti-bacterial activity of 25HC is mediated through mobilization of the accessible cholesterol pool from the plasma membrane (PM). Accessible cholesterol is one of three pools into which PM cholesterol is sub-divided and this pool regulates cellular signaling pathways that control lipid homeostasis and cell gro
