Cholesterol-Dependent γ-Secretase Activity in Buoyant Cholesterol-Rich Membrane Microdomains

Neurobiology of Disease, 2002
Buoyant membrane fractions containing presenilin 1 (PS1), an essential component of the γ-secretase complex, and APP CTFβ, a γ-secretase substrate, can be isolated from cultured cells and brain by several different fractionation procedures that are ...

Regulation of T‐cell receptor signalling by membrane microdomains [PDF]

Immunology, 2004
SummaryThere is now considerable evidence suggesting that the plasma membrane of mammalian cells is compartmentalized by functional lipid raft microdomains. These structures are assemblies of specialized lipids and proteins and have been implicated in diverse biological functions.

Arginine Metabolic Disruption Impairs Hair Regeneration via ROS‐Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia

Advanced Science, EarlyView.
Arginine deficiency accelerates androgenetic alopecia. Serum metabolome shows reduced circulating arginine, while local metabolic disruption depletes follicular reserves, triggering reactive oxygen species (ROS) accumulation and mTOR suppression that induce hair miniaturization.

Assessing Membrane Fluidity and Visualizing Fluid Membrane Domains in Bacteria Using Fluorescent Membrane Dyes

Bio-Protocol, 2018
Membrane fluidity is a key parameter of bacterial membranes that undergoes quick adaptation in response to environmental challenges and has recently emerged as an important factor in the antibacterial mechanism of membrane-targeting antibiotics.

Relationship between membrane phosphatidylinositol-4,5-bisphosphate and receptor-mediated inhibition of native neuronal M channels [PDF]

, 2005
The relationship between receptor-induced membrane phosphatidylinositol-4'5'-bisphosphate (PIP2) hydrolysis and M-current inhibition was assessed in single-dissociated rat sympathetic neurons by simultaneous or parallel recording of membrane current and ...

Creating and Modulating Microdomains in Pore‐Spanning Membranes

ChemPhysChem, 2011
AbstractThe architecture of the plasma membrane is not only determined by the lipid and protein composition, but is also influenced by its attachment to the underlying cytoskeleton. Herein, we show that microscopic phase separation of “raft‐like” lipid mixtures in pore‐spanning bilayers is strongly determined by the underlying highly ordered porous ...

Novel Swelling‐Lytic Cell Death Triggered by Cargo‐Free Ionizable Lipid Nanoparticles

Advanced Science, EarlyView.
A cargo‐free ionizable lipid nanoparticles (ipLNP) is found to induce broad swelling‐lytic cell death across multiple cell types. Cell death may be associated with lysosome membrane destabilization, involving ROS increase, lipid peroxidation, and GSDME cleavage.

What is the function of mitochondrial networks? A theoretical assessment of hypotheses and proposal for future research [PDF]

, 2015
Mitochondria can change their shape from discrete isolated organelles to a large continuous reticulum. The cellular advantages underlying these fused networks are still incompletely understood.

Repositioning Antimicrobial Peptides Against WHO‐Priority Fungi

Advanced Science, EarlyView.
The growing burden of drug‐resistant fungal infections, driven by pathogens such as Candida auris, Cryptococcus neoformans, and Aspergillus fumigatus, underscores the urgent need for novel antifungal therapies. This review explores antimicrobial peptides as promising agents with membrane‐disruptive activity, immunomodulatory properties, and delivery ...

Role of Glycosphingolipids in Formation and Function of Membrane Microdomains

Trends in Glycoscience and Glycotechnology, 2001
Recent years have been characterized by a huge interest in the structure and function of mammalian cell membrane lipid domains. The interest in this subject grew further, when their participation in important membrane-associated events such as signal transmission, cell adhesion and lipid/protein sorting was postulated. A common feature of cell membrane
