Holmium Complex with Phospholipids as 1H NMR Relaxational Sensor of Temperature and Viscosity

open access: yesMolecules, 2022
The sensitivity of Ho–phospholipid complexes to changes in the membrane viscosity of liposomes was checked. An increase in viscosity was observed for DPPC and DMPC near the phase-transition temperature.

The Roles of Membrane Rafts in CD32A-Mediated Phagocytosis [PDF]

open access: yes, 2007
Membrane rafts are highly dynamic heterogeneous sterol- and sphingolipid-rich micro-domains on cell surfaces. They are generally believed to provide residency for cell surface molecules (e.g., adhesion and signaling molecules) and scaffolding to ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Electroformation of Giant Vesicles on a Polymer Mesh

open access: yesMembranes, 2011
Electroformation of cell-sized lipid membrane vesicles (giant vesicles, GVs) from egg yolk phosphatidylcholine under applied electric voltage was examined on a substrate of a polymer mesh placed between two planar indium tin oxide coated glass electrodes.

Acetylcholinesterase Activity Influenced by Lipid Membrane Area and Surface Acoustic Waves

open access: yesMicromachines, 2022
According to the current model of nerve propagation, the function of acetylcholinesterase (AChE) is to terminate synaptic transmission of nerve signals by hydrolyzing the neurotransmitter acetylcholine (ACh) in the synaptic cleft to acetic acid (acetate)

Specific Adhesion of Membranes Simultaneously Supports Dual Heterogeneities in Lipids and Proteins [PDF]

open access: yes, 2015
Membrane adhesion is a vital component of many biological processes. Heterogeneities in lipid and protein composition are often associated with the adhesion site. These heterogeneities are thought to play functional roles in facilitating signalling. Here

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Electroformation of Giant Vesicles on Indium Tin Oxide (ITO)-Coated Poly(ethylene terephthalate) (PET) Electrodes

open access: yesMembranes, 2011
Electroformation of cell-sized lipid membrane vesicles (giant vesicles, GVs) from egg yolk phosphatidylcholine was examined using a poly(ethylene terephthalate) sheet coated with indium tin oxide (ITO-PET) as the electrode material.

Importance of Lipid Composition in the Membrane Dynamics of Urothelial Umbrella Cells [PDF]

open access: yes, 2014
The studies on membrane dynamics in urinary bladder umbrella cells were focused on proteins as important factors for maintaining the permeability barrier and their role as pathways modulators for the discoidal/fusiform endocytic vesicles which is one of ...
