Interactions between plant endomembrane systems and the actin cytoskeleton

Frontiers in Plant Science, 2015
Membrane trafficking, organelle movement and morphogenesis in plant cells are mainly controlled by the cytoskeleton. Not all proteins that regulate the actin cytoskeleton and membrane dynamics in animal systems have functional homologues in plants ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

In vivo reorganization of the actin cytoskeleton in leaves of Nicotiana tabacum L. transformed with plastin-GFP. Correlation with light-activated chloroplast responses

BMC Plant Biology, 2009
Background The actin cytoskeleton is involved in the responses of plants to environmental signals. Actin bundles play the role of tracks in chloroplast movements activated by light.

Shielding of actin by the endoplasmic reticulum impacts nuclear positioning

Nature Communications, 2022
The nucleus connects to the actin cytoskeleton for nuclear movement in migrating cells. Here, the authors show that the endoplasmic reticulum shields actin cables to generate asymmetric nucleo-cytoskeleton connections for nuclear positioning.

Arabidopsis ADF5 Acts as a Downstream Target Gene of CBFs in Response to Low-Temperature Stress

Frontiers in Cell and Developmental Biology, 2021
Low temperature is a major adverse environment that affects normal plant growth. Previous reports showed that the actin cytoskeleton plays an important role in the plant response to low-temperature stress, but the regulatory mechanism of the actin ...

Dynamic reorganization of the actin cytoskeleton [PDF]

F1000Research, 2015
Cellular processes, including morphogenesis, polarization, and motility, rely on a variety of actin-based structures. Although the biochemical composition and filament organization of these structures are different, they often emerge from a common origin. This is possible because the actin structures are highly dynamic. Indeed, they assemble, grow, and

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Microvibration stimuli causes localized depolymerization of the actin cytoskeleton of osteoblasts around the nucleus

Journal of Biomechanical Science and Engineering
Reports have indicated that microvibration stimulation activates bone remodeling and promotes bone formation. However, the mechanism by which microvibration stimulation facilitates bone formation remains incompletely understood, and it is unclear how ...

Actin Dynamics at the T Cell Synapse as Revealed by Immune-Related Actinopathies

Frontiers in Cell and Developmental Biology, 2021
The actin cytoskeleton is composed of dynamic filament networks that build adaptable local architectures to sustain nearly all cellular activities in response to a myriad of stimuli. Although the function of numerous players that tune actin remodeling is

Mythical origins of the actin cytoskeleton

Current Opinion in Cell Biology, 2021
The origin of the eukaryotic cell is one of the greatest mysteries in modern biology. Eukaryotic-wide specific biological processes arose in the lost ancestors of eukaryotes. These distinctive features, such as the actin cytoskeleton, define what it is to be a eukaryote.
