Directed cytoskeleton self-organization.

, 2012
International audienceThe cytoskeleton architecture supports many cellular functions. Cytoskeleton networks form complex intracellular structures that vary during the cell cycle and between different cell types according to their physiological role ...

Amoeboid cells undergo durotaxis with soft end polarized NMIIA

eLife
Cell migration towards stiff substrates has been coined as durotaxis and implicated in development, wound healing, and cancer, where complex interplays between immune and non-immune cells are present.

The dynamic status of actin in the regulation of environmental sensing and homeostatic control in Saccharomyces cerevisiae [PDF]

, 2014
Actin is a highly conserved protein in eukaryotes which forms dynamic cytoskeletal structures. Rapid remodeling of actin filaments is important for the regulation of a broad range of critical cellular processes.

NPFs-mediated actin cytoskeleton: a new viewpoint on autophagy regulation

Cell Communication and Signaling
Macroautophagy/autophagy is a lysosome-dependent catabolic process induced by various cellular stress conditions, maintaining the homeostasis of cells, tissues and organs.

MAP2 phosphorylation: mechanisms, functional consequences, and emerging insights

Frontiers in Cellular Neuroscience
Microtubule-associated protein 2 (MAP2) is a key regulator of cytoskeletal dynamics and neuronal function. It stabilizes microtubules, shapes dendrites, influences synaptic plasticity, and regulates transportation and protein synthesis through its ...

Tumor-derived factors impaired motility and immune functions of dendritic cells through derangement of biophysical characteristics and reorganization of cytoskeleton

, 2007
The generation and progress of tumors are accompanied with a marked suppression of human immune system. To explore the mechanisms by which tumors escape from immune recognition, we studied the influences of tumor microenvironment on differentiation of ...

The polar code for patterning: how polarity and the cytoskeleton orchestrate asymmetric cell division during plant development

Frontiers in Cell and Developmental Biology
Cell polarity is fundamental to morphogenesis across living organisms. In plants, a dynamic interplay between polarity cues and the cytoskeleton orchestrates essential asymmetric cell divisions across diverse species.

Kinetic regulation of kinesin’s two motor domains coordinates its stepping along microtubules

eLife
The two identical motor domains (heads) of dimeric kinesin-1 move in a hand-over-hand process along a microtubule, coordinating their ATPase cycles such that each ATP hydrolysis is tightly coupled to a step and enabling the motor to take many steps ...

Cytoskeleton

, 2021
Citoskelet ili stanični kostur je složena mreža bjelančevinastih niti karakterističnih za visoko organiziranu citoplazmu eukariotskih stanica. Sastoji se od najmanje tri tipa struktura: aktinskih filamenata, intermedijarnih filamenata te mikrotubula ...

β-catenin-α-catenin and actomyosin signaling differentially regulate growth cone contours and axon undulation and branching of retinal ganglion cells in situ

Frontiers in Cellular Neuroscience
IntroductionCadherin adhesive and actomyosin signaling are key cytomechanical cues required for neuronal circuit formation, but whether they function together to sculpt developing neurons is not known. Previously, we demonstrated that a β-catenin mutant (
