Biomimetic Models of the Actin Cytoskeleton

Small, 2007
AbstractThe 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

Viral manipulations of the actin cytoskeleton

Trends in Microbiology, 1997
Viruses succeed as intracellular parasites because of their ability to invade cells and appropriate the cellular machinery required during their life cycle. The actin cytoskeleton of the host cell does not escape viral infection unscathed, but is often co-opted by the virus at many different stages of its life cycle to facilitate the infection process.

Actin and microtubule cytoskeleton interactions

Current Opinion in Plant Biology, 2009
Plant 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

Evidence of Actin in the Cytoskeleton of Microsporidia

Journal of Eukaryotic Microbiology, 1999
Using transmission electron microscopy, fluorescence microscopy, immuno‐electron microscopy, and biochemical techniques such as 2‐D electrophoresis and immunoblotting, actin was found in all biological stages of the microsporidia Encephalitozoon hellem and Encephalitozoon cuniculi.

Prokaryotic origin of the actin cytoskeleton

Nature, 2001
It was thought until recently that bacteria lack the actin or tubulin filament networks that organize eukaryotic cytoplasm. However, we show here that the bacterial MreB protein assembles into filaments with a subunit repeat similar to that of F-actin-the physiological polymer of eukaryotic actin.

Apoptosis and the yeast actin cytoskeleton

Cell Death & Differentiation, 2009
Actin represents one of the most abundant and extensively studied proteins found in eukaryotic cells. It has been identified as a major target for destruction during the process of apoptosis. Recent research has also highlighted a role for cytoskeletal components in the initiation and inhibition of apoptotic processes.

Cellular Ageing and the Actin Cytoskeleton

2011
For some time the view that the actin cytoskeleton acts primarily as a scaffold, to be assembled in response to a signaling cascade as an end point in the pathway, has prevailed. However, it is now clear that the dynamic nature of the cytoskeleton is linked to downstream signaling events that further modulate cellular activity, and which can determine ...

Role of actin cytoskeleton in podocytes

Pediatric Nephrology, 2020
The selectivity of the glomerular filter is established by physical, chemical, and signaling interplay among its three core constituents: glomerular endothelial cells, the glomerular basement membrane, and podocytes. Functional impairment or injury of any of these three components can lead to proteinuria.

Membrane interactions with the actin cytoskeleton

Current Opinion in Cell Biology, 1994
Recent advances have been made in our understanding of the direct binding of actin to integral membrane proteins. New information has been obtained about indirect actin-membrane associations through spectrin superfamily members and through proteins at the cytoplasmic surfaces of focal contacts and adherens junctions.
