Modelling single cell electroporation with bipolar pulse parameters and dynamic pore radii [PDF]

open access: yes, 2010
We develop a model of single spherical cell electroporation and simulate spatial and temporal aspects of the transmembrane potential and pore radii as an effect of any form of applied electric field.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Fusion Pore Selectivity in Chromaffin Cells [PDF]

open access: yesBiophysical Journal, 2017
Healthy physiological conditions depend on dynamic release of neurotransmitters and hormones by exocytosis, which is initiated by the fusion pore. Previous studies show that reduction of extracellular [NaCl] decreases the amperometric foot current, indicating no co-release of anions with transmitter.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Regulation of Exocytotic Fusion Pores by SNARE Protein Transmembrane Domains

open access: yesFrontiers in Molecular Neuroscience, 2017

Minimum Membrane Bending Energies of Fusion Pores [PDF]

open access: yesJournal of Membrane Biology, 2009
Membranes fuse by forming highly curved intermediates, culminating in structures described as fusion pores. These hourglass-like figures that join two fusing membranes have high bending energies, which can be estimated using continuum elasticity models.

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

Vesicular release of glutamate utilizes the proton gradient between the vesicle and synaptic cleft

open access: yesFrontiers in Synaptic Neuroscience, 2010
Glutamate is released from synaptic vesicles following formation of a fusion pore, connecting the vesicle interior with the synaptic cleft. Release is proposed to result from either full fusion of the vesicle with the terminal membrane or by ‘kiss-

Fusion Pore Conductance: Experimental Approaches and Theoretical Algorithms [PDF]

open access: yesBiophysical Journal, 1998
Time-resolved admittance measurements provide the basis for studies showing that membrane fusion occurs through the formation and widening of an initially small pore, linking two previously separated aqueous compartments. Here we introduce modifications to this method that correct the cell-pipette (source) admittance for attenuation and phase shifts ...
