Lipid-modifying enzyme: New target for pan-viral therapeutics
Three different disease-causing viruses -- poliovirus, coxsackievirus, and hepatitis C -- rely on their unwilling host for the membrane platforms enriched in a specific lipid, phosphatidylinositol 4 phosphate (PI4P) on which ...

Multi-compartment globular structures assembled from polymer-based materials may soon serve as cell prototypes
The cell is a host of many complex reaction pathways. These pathways usually do not interfere with each other because they are contained within membrane-bound compartments, known as organelles. The lipid membrane is extremely ...
