Modeling Membrane Morphological Change during Autophagosome Formation
iScience, 2020 Summary: Autophagy is an intracellular degradation process that is mediated by de novo formation of autophagosomes. Autophagosome formation involves dynamic morphological changes; a disk-shaped membrane cisterna grows, bends to become a cup-shaped ...

Canards and curvature: nonsmooth approximation by pinching [PDF]
, 2011 In multiple time-scale (singularly perturbed) dynamical systems, canards are counterintuitive solutions that evolve along both attracting and repelling invariant manifolds.

The influence of solid scaffolds on flat and curved lipid membranes
AIP Advances, 2017 Solid-supported membranes have become a common tool to study lipid membrane properties in a controlled environment. One particular example is the study of membrane curvature and its effect on lipid sorting.

Reliable estimation of membrane curvature for cryo-electron tomography.
PLoS Computational Biology, 2020 Curvature is a fundamental morphological descriptor of cellular membranes. Cryo-electron tomography (cryo-ET) is particularly well-suited to visualize and analyze membrane morphology in a close-to-native state and molecular resolution.

Interactions of human islet amyloid polypeptide with lipid structure of different curvatures
Theoretical and Applied Mechanics Letters, 2020 : Curvature is one of the most important features of lipid membranes in living cells, which significantly influences the structure of lipid membranes and their interaction with proteins.

Membrane-mediated interactions between disk-like inclusions adsorbed on vesicles
Frontiers in Physics, 2022 Self-assembly of membrane inclusions plays a key role in biological processes such as cellular signalling and trafficking and has potential applications for designing interfacial devices such as sensors and actuators.

Finite element methods for director fields on flexible surfaces [PDF]
, 2012 We introduce a nonlinear model for the evolution of biomembranes driven by the L-2-gradient flow of a novel elasticity functional describing the interaction of a director field on a membrane with its curvature.

Membranes, 2017 The shape and composition of a membrane directly regulate the localization, activity, and signaling properties of membrane associated proteins. Proteins that both sense and generate membrane curvature, e.g., through amphiphilic insertion motifs ...

eLife, 2020 Vesicle fusion is mediated by assembly of SNARE proteins between opposing membranes. While previous work suggested an active role of SNARE transmembrane domains (TMDs) in promoting membrane merger (Dhara et al., 2016), the underlying mechanism remained ...
