Eukaryotic cells are organized into a complex system of subcompartments, each with its distinct protein and lipid composition. A continuous flux of membranes crosses these compartments, and in some cases direct connections exist between the different organ ...
We show that a two-step process, involving spontaneous self-assembly of lipids and apolipoproteins and surface patterning, produces single, supported lipid bilayers over two discrete and independently adjustable length scales. Specifically, an aqueous phas ...
The observation that the membranes of flagella are enriched in sterols and sphingolipids has led to the hypothesis that flagella might be enriched in raft-forming lipids. However, a detailed lipidomic analysis of flagellar membranes is not available. Novel ...
Rather than being distributed homogeneously on the cell surface, proteins are probably aggregated in clusters or in specific domains. Some of these domains (lipid rafts) have lipid compositions, which differ from their surrounding membrane. They have been ...
Phosphoinositides are involved in a large number of processes in cells and it is very demanding to study individual protein-lipid interactions in vivo due to their rapid turnover and involvement in simultaneous events. Supported lipid bilayers (SLBs) conta ...
High-density lipoprotein (HDL) particles are cholesterol and lipid transport containers. Mature HDL particles destined for the liver develop through the formation of intermediate discoidal HDL particles, which are the primary acceptors for cholesterol. Her ...
Erythrocytes are attractive as potential cell-based drug carriers because of their abundance and long life-span in vivo. Existing methods for loading drug cargos into erythrocytes include hypotonic treatments, electroporation, and covalent attachment onto ...
Recent work has demonstrated that charged gold nanoparticles (AuNPs) protected by an amphiphilic organic monolayer can spontaneously insert into the core of lipid bilayers to minimize the exposure of hydrophobic surface area to water. However, the kinetic ...
Hepatitis B surface antigen (HBsAg) subvirus particles produced from yeast share immunological determinants with mature viruses, which enable the use of HBsAg as a potent antigen for human vaccination. Because the intimate structure of such pseudoviral par ...
We report a method for making ultra-thin PDMS membrane devices. Freely suspended membranes as thin as 70 nm have been fabricated. Bulging tests were performed with a custom built fluidic cell to characterize large circular membranes. The fluidic cell allow ...
