Cholesterol Hinders the Passive Uptake of Amphiphilic Nanoparticles into Fluid Lipid Membranes

Francesco Stellacci, Matteo Gasbarri, Ester Canepa, Giulia Rossi

Plasma membranes represent pharmacokinetic barriers for the passive transport of site-specific drugs within cells. When engineered nanoparticles (NPs) are considered as transmembrane drug carriers, the plasma membrane composition can affect passive NP inte ...

The role of xanthophylls in the supramolecular organization of the photosynthetic complex LHCII in lipid membranes studied by high-resolution imaging and nanospectroscopy

Giovanni Dietler, Jiangtao Zhou

The xanthophyll cycle is a regulatory mechanism operating in the photosynthetic apparatus of plants. It consists of the conversion of the xanthophyll pigment violaxanthin to zeaxanthin, and vice versa, in response to light intensity. According to the curre ...

pH sensing by lipids in membranes: The fundamentals of pH-driven migration, polarization and deformations of lipid bilayer assemblies

Anne-Florence Raphaëlle Bitbol

Most biological molecules contain acido-basic groups that modulate their structure and interactions. A consequence is that pH gradients, local heterogeneities and dynamic variations are used by cells and organisms to drive or regulate specific biological f ...

Optical Antenna-Based Fluorescence Correlation Spectroscopy to Probe the Nanoscale Dynamics of Biological Membranes

Jürgen Brugger, Pamina Winkler, Valentin Flauraud, Raju Regmi

The plasma membrane of living cells is compartmentalized at multiple spatial scales ranging from the nano- to the mesoscale. This nonrandom organization is crucial for a large number of cellular functions. At the nanoscale, cell membranes organize into dyn ...

Monitoring Membrane Lipidome Turnover by Metabolic N-15 Labeling and Shotgun Ultra-High-Resolution Orbitrap Fourier Transform Mass Spectrometry

Yury Tsybin, Konstantin Nagornov, Kristina Srzentic

Lipidomes undergo permanent extensive remodeling, but how the turnover rate differs between lipid classes and molecular species is poorly understood. We employed metabolic N-15 labeling and shotgun ultra-high-resolution mass spectrometry (sUHR) to quantify ...

Solution structure of discoidal high-density lipoprotein particles with a shortened apolipoprotein A-I

Henning Paul-Julius Stahlberg

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 ...

The effects of globotriaosylceramide tail saturation level on bilayer phases

Julian Charles Shillcock

Globotriaosylceramide (Gb(3)) is a glycosphingolipid present in the plasma membrane that is the natural receptor of the bacterial Shiga toxin. The unsaturation level of Gb(3) acyl chains has a drastic impact on lipid bilayer properties and phase behaviour, ...

Influence of the glycocalyx and plasma membrane composition on amphiphilic gold nanoparticle association with erythrocytes

Francesco Stellacci, Paulo Henrique Jacob Silva, Randy Patrick Carney, Ye Yang, Ahmet Bekdemir

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 ...
