Visualization and Manipulation of Actin Cytoskeleton with Small-Molecular Probes [PDF]

, 2020
Actin is a ubiquitous cytoskeletal protein, forming a dynamic network that generates mechanical forces in the cell. Here, in order to dissect the complex mechanisms of actin-related cellular functions, we introduce two powerful tools based on a new class

PFA fixation enables artifact-free super-resolution imaging of the actin cytoskeleton and associated proteins

Biology Open, 2016
Super-resolution microscopy (SRM) allows precise localization of proteins in cellular organelles and structures, including the actin cytoskeleton. Yet sample preparation protocols for SRM are rather anecdotal and still being optimized.

Filamin A in platelets: Bridging the (signaling) gap between the plasma membrane and the actin cytoskeleton

Frontiers in Molecular Biosciences, 2022
Platelets are anucleate cells that are essential for hemostasis and wound healing. Upon activation of the cell surface receptors by their corresponding extracellular ligands, platelets undergo rapid shape change driven by the actin cytoskeleton; this ...

Modulation of NF-kappaB activation in Theileria annulata-infected cloned cell lines is associated with detection of parasite-dependent IKK signalosomes and disruption of the actin cytoskeleton [PDF]

, 2010
Apicomplexan parasites within the genus <i>Theileria</i> have the ability to induce continuous proliferation and prevent apoptosis of the infected bovine leukocyte.

Alteration of the cortical actin cytoskeleton deregulates Ca2+ signaling, monospermic fertilization, and sperm entry. [PDF]

PLoS ONE, 2008
BackgroundWhen preparing for fertilization, oocytes undergo meiotic maturation during which structural changes occur in the endoplasmic reticulum (ER) that lead to a more efficient calcium response. During meiotic maturation and subsequent fertilization,

A role for Vps1p, actin, and the Myo2p motor in peroxisome abundance and inheritance in Saccharomyces cerevisiae [PDF]

, 2001
In vivo time-lapse microscopy reveals that the number of peroxisomes in Saccharomyces cerevisiae cells is fairly constant and that a subset of the organelles are targeted and segregated to the bud in a highly ordered, vectorial process.

Studies on the role of cholesterol and coronin 1 in antigen-presenting cells [PDF]

, 2005
Antigen recognition and presentation to subsequently induce an appropriate host response is dependent on the action of antigen-presenting cells such as dendritic cells and macrophages.

Yeast as a Model to Understand Actin-Mediated Cellular Functions in Mammals-Illustrated with Four Actin Cytoskeleton Proteins [PDF]

, 2020
The budding yeast Saccharomyces cerevisiae has an actin cytoskeleton that comprises a set of protein components analogous to those found in the actin cytoskeletons of higher eukaryotes. Furthermore, the actin cytoskeletons of S.

When fat is not bad: the regulation of actin dynamics by phospholipid signaling molecules

Frontiers in Plant Science, 2014
The actin cytoskeleton plays a key role in the plant morphogenesis and is involved in polar cell growth, movement of subcellular organelles, cell division, and plant defense.

Intracellular tension sensor reveals mechanical anisotropy of the actin cytoskeleton

Nature Communications, 2023
The filamentous actin (F-actin) cytoskeleton is a composite material consisting of cortical actin and bundled F-actin stress fibers, which together mediate the mechanical behaviors of the cell, from cell division to cell migration. However, as mechanical
