Advanced Materials, EarlyView.A cholesterol‐conjugated lipid library enabled the identification of a ligand‐free LNP platform for efficient mRNA delivery to brain endothelial cells via systemic administration. This platform achieves selective BBB targeting without disrupting barrier integrity, and enables modulation of neuroinflammation and vascular function without requiring trans‐

Inhibition of HIV Replication by Apolipoprotein A-I Binding Protein Targeting the Lipid Rafts
mBio, 2020 Apolipoprotein A-I binding protein (AIBP) is a protein involved in regulation of lipid rafts and cholesterol efflux. AIBP has been suggested to function as a protective factor under several sets of pathological conditions associated with increased ...

Advanced Science, EarlyView.Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Targeting Lipid Rafts as a Strategy Against Coronavirus
Frontiers in Cell and Developmental Biology, 2021 Lipid rafts are functional membrane microdomains containing sphingolipids, including gangliosides, and cholesterol. These regions are characterized by highly ordered and tightly packed lipid molecules.

Lipid rafts and membrane dynamics [PDF]
Journal of Cell Science, 2005 Cell membranes contain a variety of lipid species that differ in their physico-chemical properties. Lipid-lipid immiscibility gives rise to lateral heterogeneities in the membrane plane, a subset of which are termed lipid rafts ([Simons and Vaz, 2004][1]).

Advanced Science, EarlyView.This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

Role of amphipathic helix of a herpesviral protein in membrane deformation and T cell receptor downregulation. [PDF]
PLoS Pathogens, 2008 Lipid rafts are membrane microdomains that function as platforms for signal transduction and membrane trafficking. Tyrosine kinase interacting protein (Tip) of T lymphotropic Herpesvirus saimiri (HVS) is targeted to lipid rafts in T cells and ...

Advanced Science, EarlyView.This study unravels that bone fracture accelerates diabetic wound healing by releasing exosomal microRNA (miR‐130b‐3p). To mimic this bone‐skin crosstalk, we engineered a self‐assembling agomir‐130b‐3p nanocomplex. Delivered via a photocrosslinkable hydrogel, this bio‐inspired therapy provides sustained localized agomir release.

Angewandte Chemie, EarlyView.We report a super‐resolution strategy that maps cholesterol‐rich membrane domains in whole, intact cells with an effective spatial resolution of ∼40 nm by combining expansion microscopy with a perfringolysin O domain 4 probe. This approach enables direct visualization of the spatial association between CD20 and CD38 complexes and cholesterol‐rich ...
