Spatial cytoskeleton organization supports targeted intracellular transport [PDF]
The efficiency of intracellular cargo transport from specific source to target locations is strongly dependent upon molecular motor-assisted motion along the cytoskeleton. Radial transport along microtubules and lateral transport along the filaments of the actin cortex underneath the cell membrane are characteristic for cells with a centrosome.

Patterns in Space: Coordinating Adhesion and Actomyosin Contractility at E-cadherin Junctions
Cadherin adhesion receptors are fundamental determinants of tissue organization in health and disease. Increasingly, we have come to appreciate that classical cadherins exert their biological actions through active cooperation with the contractile actin ...

Crosstalk between cell adhesion and the actin cytoskeleton [PDF]
In order to form tissues and to move, cells need to attach to the surrounding environment. Integrins are the major cell adhesion receptors that cells use to attach to the extracellular matrix on the outside of the cell, and to recruit a large adhesion ...

core
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

Theory of active self-organization of dense nematic structures in the actin cytoskeleton [PDF]
The actin cytoskeleton is remarkably adaptable and multifunctional. It often organizes into nematic bundles such as contractile rings or stress fibers. However, how a uniform and isotropic actin gel self-organizes into dense nematic bundles is not fully understood.

A minimal model of plasma membrane heterogeneity requires coupling cortical actin to criticality [PDF]
We present a minimal model of plasma membrane heterogeneity that combines criticality with connectivity to cortical cytoskeleton. Our model is motivated by recent observations of micron-sized critical fluctuations in plasma membrane vesicles that are detached from their cortical cytoskeleton. We incorporate criticality using a conserved order parameter

A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Actin automata: Phenomenology and localizations [PDF]
Actin is a globular protein which forms long filaments in the eukaryotic cytoskeleton, whose roles in cell function include structural support, contractile activity to intracellular signalling. We model actin filaments as two chains of one-dimensional binary-state semi-totalistic automaton arrays to describe hypothetical signalling events therein. Each

Endocytosis, Actin Cytoskeleton, and Signaling [PDF]
Endocytosis is the internalization of plasma membrane proteins and lipids, extracellular molecules, fluids, particles, exosomes, viruses, and bacteria. Endocytic internalization is a conserved process for all eukaryotic cells that is required for diverse cellular functions.
