The actin cytoskeleton is involved in the transport and positioning of Golgi bodies, but the actin-based processes that determine the positioning and motility behavior of Golgi bodies are not well understood. In this work, we have studied the relationship between Golgi body motility behavior and actin organization in intercalary growing root epidermal cells during different developmental stages...

We report a general strategy for spatiotemporal control of actin polymerization in vitro using photoactivatable actin. Caged actin was synthesized by chemically modified lysine residues on monomeric actin and released with focused ultraviolet (UV) illumination. Epifluorescence microscopy revealed nucleation and elongation of individual actin filaments (8 nm in diameter) after localized release ...

Unlike a static and immobile skeleton, the actin cytoskeleton is a highly dynamic network of filamentous actin (F-actin) polymers that continuously turn over. In addition to generating mechanical forces and sensing mechanical deformation, dynamic F-actin networks serve as cellular tracks for myosin motor traffic. However, much of our mechanistic understanding of processive myosins comes from in...

Cell stiffening induced by anticancer microtubule targeting drugs (MTDs) such as vinflunine (VFL), colchicine (COL), and docetaxel (DTX) can be driven crosstalk between actin filaments microtubules.

Dendritic cells (DCs) are crucial for the priming of naive T and initiation adaptive immunity. Priming is initiated at a heterologous cell–cell contact, immunological synapse (IS). While it established that F-actin dynamics regulates signaling cell side little known about cytoskeletal contribution on DC side. Here, we show actin cytoskeleton decisive formation multifocal synaptic structure, whi...
