Dynamics of the Actin Cytoskeleton at Adhesion Complexes

Biology, 2021
The shape of cells is altered to allow cells to adapt to their changing environments, including responding to internally generated and externally applied force. Force is sensed by cell surface adhesion proteins that are enriched in sites where cells bind

A functional link between the actin cytoskeleton and lipid rafts during budding of filamentous influenza virions [PDF]

, 2002
Morphogenesis of influenza virus is a poorly understood process that produces two types of enveloped virion: approximately 100-nm spheres and similar diameter filaments that reach 20 microm in length. Spherical particles assemble at plasma membrane lipid

Bending over backwards: BAR proteins and the actin cytoskeleton in mammalian receptor-mediated endocytosis

European Journal of Cell Biology, 2022
The role of the actin cytoskeleton during receptor-mediated endocytosis (RME) has been well characterized in yeast for many years. Only more recently has the interplay between the actin cytoskeleton and RME been extensively explored in mammalian cells ...

Visualization of Endothelial Actin Cytoskeleton in the Mouse Retina [PDF]

, 2012
Angiogenesis requires coordinated changes in cell shape of endothelial cells (ECs), orchestrated by the actin cytoskeleton. The mechanisms that regulate this rearrangement in vivo are poorly understood - largely because of the difficulty to visualize ...

Physical mechanism of the compressive response of F-actin networks: significance of crosslinker unbinding events

Theoretical and Applied Mechanics Letters, 2014
A model of crosslinker unbinding is implemented in a highly coarse-grained granular model of F-actin cytoskeleton. We employ this specific granular model to study the mechanisms of the compressive responses of F-actin networks.

Sensor potency of the moonlighting enzyme-decorated cytoskeleton [PDF]

, 2013
Background: There is extensive evidence for the interaction of metabolic enzymes with the eukaryotic cytoskeleton. The significance of these interactions is far from clear.

Studies on the role of Coronin 1 and the actin cytoskeleton in T cell signaling and survival [PDF]

, 2009
Calcium ions (Ca2+) function as universal second messengers in most if not all eukaryotic cells, including the cells of the immunesystem. Ca2+ signals are required for the proper activation of lymphocytes, such as T-lymphocytes, their proliferation ...

Bardet-Biedl syndrome proteins control cilia length through regulation of actin polymerisation. [PDF]

, 2012
Primary cilia are cellular appendages important for signal transduction and sensing the environment. Bardet-Biedl syndrome proteins form a complex that is important for several cytoskeleton-related processes such as ciliogenesis, cell migration and ...

Modulation of TMEM16A-Channel Activity as Ca2+ Activated Cl− Conductance via the Interaction With Actin Cytoskeleton in Murine Portal Vein

Journal of Pharmacological Sciences, 2014
.: TMEM16A is a major component of Ca2+-activated Cl− channel (CaCC) conductance in murine portal vein smooth muscle cells (mPVSMCs). Here, the regulation of CaCC activity by the actin cytoskeleton was examined in mPVSMCs.

Ultrastructure of the actin cytoskeleton [PDF]

Current Opinion in Cell Biology, 2018
The actin cytoskeleton is the primary force-generating machinery in the cell, which can produce pushing (protrusive) forces using energy of actin polymerization and pulling (contractile) forces via sliding of bipolar filaments of myosin II along actin filaments, as well as perform other key functions.
