The Leukocyte Actin Cytoskeleton
Bulletin de l'Institut Pasteur, 1996The main task of leukocytes is to patrol throughout the body in order to detect and eliminate potentially harmful structures such as invading microorganisms or effete cells. The fulfilment of these functions often requires that cells undergo drastic morphological changes. These changes may be passive, e.g.

Actin and microtubule cytoskeleton interactions
Current Opinion in Plant Biology, 2009Plant cytoskeleton consists of two major networks of protein polymers, actin microfilaments (AFs) and microtubules (MTs). These networks perform numerous functions that are essential for cell division and for maintaining the integrity of cytoplasm required for intracellular transport and cell shape. Besides the more or less indirect cooperation between

SIGNALING TO THE ACTIN CYTOSKELETON
Annual Review of Cell and Developmental Biology, 1998▪ Abstract The actin cytoskeleton is a highly dynamic network composed of actin polymers and a large variety of associated proteins. The main functions of the actin cytoskeleton are to mediate cell motility and cell shape changes during the cell cycle and in response to extracellular stimuli, to organize the cytoplasm, and to generate mechanical ...

Actin cytoskeleton and sperm function
Biochemical and Biophysical Research Communications, 2018For the acquisition of the ability to fertilize the egg, mammalian spermatozoa should undergo a series of biochemical transformations in the female reproductive tract, collectively called capacitation. The capacitated sperm can undergo the acrosomal exocytosis process near or on the oocyte, which allows the spermatozoon to penetrate and fertilize it ...

Integrins and the actin cytoskeleton
Current Opinion in Cell Biology, 2007The ability to connect to the actin cytoskeleton is a key part of the adhesive function of integrins. This linkage between integrins and the cytoskeleton involves a large complex of integrin-associated proteins that function in both the assembly and disassembly of the link.

Biomimetic Models of the Actin Cytoskeleton
Small, 2007AbstractThe cytoskeleton is a complex polymer network that plays an essential role in the functionality of eukaryotic cells. It endows cells with mechanical stability, adaptability, and motility. To identify and understand the mechanisms underlying this large variety of capabilities and to possibly transfer them to engineered networks makes it ...

INTRACELLULAR PATHOGENS AND THE ACTIN CYTOSKELETON
Annual Review of Cell and Developmental Biology, 1998▪ Abstract Many pathogens actively exploit the actin cytoskeleton during infection. This exploitation may take place during entry into mammalian cells after engagement of a receptor and/or as series of signaling events culminating in the engulfment of the microorganism. Although actin rearrangements are a common feature of most internalization events

Actin Cytoskeleton: Through the bottleneck
Current Biology, 1994Like serendipity-alpha and nullo, the newly characterized gene bottleneck is involved in organizing the actin cytoskeleton of the Drosophila embryo to achieve the transition from a syncytium to a cellular blastoderm.

Actin cytoskeleton and cell signaling
Critical Care Medicine, 2000The role of the actin cytoskeleton in the function of eukaryotic cells is ubiquitous. Regulation of actin polymerization allows cells to control their shape, to move, divide, secrete, and phagocytose. Actin filaments provide strength, connections to other cells and the extracellular matrix, paths for intracellular transport and a scaffold for ...

GPCRs and actin–cytoskeleton dynamics
2016A multitude of physiological processes regulated by G protein-coupled receptors (GPCRs) signaling are accomplished by the participation of active rearrangements of the cytoskeleton. In general, it is common that a cross talk occurs among networks of microfilaments, microtubules, and intermediate filaments in order to reach specific cell responses.
