'Targeting lipid rafts as a strategy against infection and cancer"

 

Short summary of the work: 

Lipid rafts are membrane micro-domains that are enriched in cholesterol, sphingomyelin, sphingolipids and phospholipids. Their importance for living cells is underlined by their involvement in many processes including bacterial and viral entry, cardiovascular and prion diseases as well as cancer. Targeting lipid rafts is emerging as an innovative strategy to limit bacterial or viral infection and to increase the sensitivity to apoptosis of different types of tumours. Behind well-known cholesterol depleting agents (cyclodextrin) new compounds involved in cholesterol homeostasis were recently discovered. These potential drug candidates are capable to modify the lipid rafts composition and to alter the signalling platform associated with them.  Multiple technologies including confocal microscopy to visualize lipid rafts, viability assays to determine the toxic effect of compounds on the cells, offer the opportunity to study in details the changes induced by this new class of cholesterol-targeting agents.
