Physical effects of cholesterol on arterial smooth muscle membranes: evidence of immiscible cholesterol domains and alterations in bilayer width during atherogenesis

Journal of Lipid Research, 1998
Small angle X-ray diffraction was used to examine arterial smooth muscle cell (SMC) plasma membranes isolated from control and cholesterol-fed (2%) atherosclerotic rabbits.

Lipid Nanoparticle Co‐Delivery of mRNA and a Small Molecule Drug for Oral Cancer Chemoimmunotherapy

Advanced Materials, EarlyView.
Co‐encapsulation of p53 mRNA and the small molecule ciclopirox within a lipid nanoparticle yields an all‐in‐one chemoimmunotherapy for oral squamous cell carcinoma. The platform engages caspase‐driven apoptosis in cancer cells while repolarizing tumor‐associated macrophages, achieving tumor reduction in both p53‐susceptible and p53‐resistant models and

The Importance of Bilayer Asymmetry in Biological Membranes: Insights from Model Membranes

Membranes
This mini-review intends to highlight the importance of bilayer asymmetry. Biological membranes are complex structures that are a physical barrier separating the external environment from the cellular content.

Polysaccharide-supported planar bilayer lipid model membranes [PDF]

, 2003
Bilayer lipid membranes were deposited onto two different thin water swellable polymer cushions predominantly by Langmuir-Blodgett trough methods. Membranes consisting of zwitterionic lipids supported by agarose films were shown to be unstable, as ...

Influence of PLIN5 and lipid composition on lipid droplet contact sites with other organelles

Biochemistry and Biophysics Reports
Lipid droplets (LDs) maintain cellular lipid homeostasis through dynamic interactions with other organelles. Understanding how these contact sites form is crucial for uncovering the mechanisms of lipid exchange and signaling. In this study, we used an in

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow

Advanced Materials Interfaces, EarlyView.
A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...
