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.

Nanoclustering as a dominant feature of plasma membrane organization [PDF]
, 2014 Early studies have revealed that some mammalian plasma membrane proteins exist in small nanoclusters. The advent of super-resolution microscopy has corroborated and extended this picture, and led to the suggestion that many, if not most, membrane ...

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

Actin Cytoskeleton and Golgi Involvement in Barley stripe mosaic virus Movement and Cell Wall Localization of Triple Gene Block Proteins. [PDF]
, 2013 Barley stripe mosaic virus (BSMV) induces massive actin filament thickening at the infection front of infected Nicotiana benthamiana leaves. To determine the mechanisms leading to actin remodeling, fluorescent protein fusions of the BSMV triple gene ...

PECAM-1 engagement counteracts ICAM-1-induced signaling in brain vascular endothelial cells [PDF]
, 2007 Interactions between leukocytes and vascular endothelial cells are mediated by a complex set of membrane adhesion molecules which transduce bi-directional signals in both cell types.
