Prenematic Fluctuations in Nanoparticle-Hosted Systems
Szymon Starzonek, Krzysztof Górny, Zbigniew Dendzik +2
This study combines broadband dielectric spectroscopy (BDS) experiments with molecular dynamics (MD) simulations to investigate the influence of nanoparticle (NP) inclusions on pre…
Coupling Anisotropic Curvature and Nematic Order: Mechanisms of Membrane Shape Remodeling
Yoav Ravid, Samo Penič, Luka Mesarec +4
This study theoretically investigates how anisotropic curved membrane components (CMCs) control vesicle morphology through curvature sensing, nematic alignment, topological defects…
Symmetry and Critical Dynamics in Supercooled Liquid Crystals: Insights into the Glass Transition
Szymon Starzonek, Aleš Iglič, Aleksandra Drozd-Rzoska +1
This study introduces a modeling approach aimed at elucidating the pivotal role of symmetry in phase transitions, focusing specifically on the isotropic-nematic (I-N) transition ch…
Numerical studies of triangulated vesicles with anisotropic membrane inclusions
Yoav Ravid, Samo Penič, Nir Gov +3
In this study, we implement the deviatoric curvature model to examine dynamically triangulated surfaces with anisotropic membrane inclusions. The Monte-Carlo numerical scheme is de…
A minimal physical model for curvotaxis driven by curved protein complexes at the cell's leading edge
Raj Kumar Sadhu, Marine Luciano, Wang Xi +12
Cells often migrate on curved surfaces inside the body, such as curved tissues, blood vessels or highly curved protrusions of other cells. Recent \textit{in-vitro} experiments prov…
Coiling of cellular protrusions around extracellular fibers
Raj Kumar Sadhu, Christian Hernandez-Padilla, Yael Eshed Eisenbach +8
Protrusions at the leading-edge of a cell play an important role in sensing the extracellular cues, during cellular spreading and motility. Recent studies provided indications that…
Theoretical model of efficient phagocytosis driven by curved membrane proteins and active cytoskeleton forces
Raj Kumar Sadhu, Sarah R Barger, Samo Penič +4
Phagocytosis is the process of engulfment and internalization of comparatively large particles by the cell, that plays a central role in the functioning of our immune system. We st…
Modelling cellular spreading and emergence of motility in the presence of curved membrane proteins and active cytoskeleton forces
Raj Kumar Sadhu, Samo Penič, Aleš Iglič +1
Eukaryotic cells adhere to extracellular matrix during the normal development of the organism, forming static adhesion as well as during cell motility. We study this process by con…
