Defining the Diffusion in Model Membranes Using Line Fluorescence Recovery after Photobleaching

open access: yesMembranes, 2020
In this study, we explore the use of line FRAP to detect diffusion in synthetic lipid membranes. The study of the dynamics of these membrane lipids can, however, be challenging.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Protocol for building synthetic protocell membranes that sense redox using synthetic phospholipids and natural lipids

open access: yesSTAR Protocols
Summary: Sensing is a critical function of artificial cells; however, this is challenging to realize using bottom-up approaches. Here, we present a protocol for building protocell membranes that sense cues important for redox biochemistry and signaling ...

Genetically controlled membrane synthesis in liposomes

open access: yesNature Communications, 2020
Controlled membrane synthesis in liposomes is a prerequisite for synthetic systems emulating the fundamental properties of living cells. Here authors present that a de novo synthesized metabolic pathway converts precursors into a variety of lipids ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Protein regulation by phosphatidylinositol lipids

open access: yes, 1995
Phosphatidylinositol lipids are best known as a source of the second messengers inositol trisphosphate and diacylglycerol. Some phosphatidylinositol lipids may directly regulate cytoskeletal events, however. To understand the role of lipids in signaling,

Membrane lipids and their degradation compounds control GM2 catabolism at intralysosomal luminal vesicles

open access: yesJournal of Lipid Research, 2019
The catabolism of ganglioside GM2 is dependent on three gene products. Mutations in any of these genes result in a different type of GM2 gangliosidosis (Tay-Sachs disease, Sandhoff disease, and the B1 and AB variants of GM2 gangliosidosis), with GM2 as ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Preparation and Characterization of Ginger Lipid-derived Nanoparticles for Colon-targeted siRNA Delivery

open access: yesBio-Protocol, 2020
Synthetic nanoparticle-based drug delivery system is widely known for its ability to increase the efficacy and specificity of loaded drugs, but it often suffers from relatively higher immunotoxicity and higher costs as compared to traditional drug ...

Aminosugar-based immunomodulator lipid A: synthetic approaches [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2018
The immediate immune response to infection by Gram-negative bacteria depends on the structure of a lipopolysaccharide (LPS, also known as endotoxin), a complex glycolipid constituting the outer leaflet of the bacterial outer membrane. Recognition of picomolar quantities of pathogenic LPS by the germ-line encoded Toll-like Receptor 4 (TLR4) complex ...
