Nonconverged Constraints Cause Artificial Temperature Gradients in Lipid Bilayer Simulations. [PDF]
J Phys Chem B, 2021 [Image: see text] Molecular dynamics (MD) simulations have become an indispensable tool to investigate phase separation in model membrane systems. In particular, simulations based on coarse-grained (CG) models have found widespread use due to their ...

Understanding the Functional Properties of Lipid Heterogeneity in Pulmonary Surfactant Monolayers at the Atomistic Level. [PDF]
Front Cell Dev Biol, 2020 Pulmonary surfactant is a complex mixture of lipids and proteins lining the interior of the alveoli, and constitutes the first barrier to both oxygen and pathogens as they progress toward blood circulation.

Membrane curvature sensing and symmetry breaking of the M2 proton channel from Influenza A. [PDF]
ElifeThe M2 proton channel aids in the exit of mature influenza viral particles from the host plasma membrane through its ability to stabilize regions of high negative Gaussian curvature (NGC) that occur at the neck of budding virions.

Biophysical Studies of Cholesterol in Unsaturated Phospholipid Model Membranes [PDF]
, 2013 Cellular membranes contain a staggering diversity of lipids. The lipids are heterogeneously distributed to create regions, or domains, whose physical properties differ from the bulk membrane and play an essential role in modulating the function of ...
