Cells Dynamically Adapt to Surface Geometry by Remodeling Their Focal Adhesions and Actin Cytoskeleton

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cells probe their environment and adapt their shape accordingly via the organization of focal adhesions and the actin cytoskeleton. In an earlier publication, we described the relationship between cell shape and physiology, for example, shape-induced ...

Deformation of an elastic cell in a uniform stream and in a circulatory flow [PDF]

open access: yes, 2013
The deformation of a circular, inextensible elastic cell is examined when the cell is placed into two different background potential flows: a uniform stream and a circulatory flow induced by a point vortex located inside the cell. In a circulatory flow a

Essential role of the endocytic site-associated protein Ecm25 in stress-induced cell elongation

open access: yesCell Reports, 2021
Summary: How cells adopt a different morphology to cope with stress is not well understood. Here, we show that budding yeast Ecm25 associates with polarized endocytic sites and interacts with the polarity regulator Cdc42 and several late-stage endocytic ...

IAPs on the move : role of inhibitors of apoptosis proteins in cell migration [PDF]

open access: yes, 2013
Inhibitors of Apoptosis Proteins (IAPs) are a class of highly conserved proteins predominantly known for the regulation of caspases and immune signaling. However, recent evidence suggests a crucial role for these molecules in the regulation of tumor cell

Cell-Responsive Shape Memory Polymers

open access: yesACS Biomaterials Science & Engineering, 2022
Recent decades have seen substantial interest in the development and application of biocompatible shape memory polymers (SMPs), a class of "smart materials" that can respond to external stimuli. Although many studies have used SMP platforms triggered by thermal or photothermal events to study cell mechanobiology, SMPs triggered by cell activity have ...

Secreted retropepsin-like enzymes are essential for stress tolerance and biofilm formation in Pseudomonas aeruginosa

open access: yesmBio
Proteases regulate important biological functions. Here, we present the structural and functional characterization of three previously uncharacterized aspartic proteases in Pseudomonas aeruginosa. We show that these proteases have structural hallmarks of

Distinct regions of H. pylori’s bactofilin CcmA regulate protein–protein interactions to control helical cell shape

open access: yeseLife, 2022
The helical shape of Helicobacter pylori cells promotes robust stomach colonization; however, how the helical shape of H. pylori cells is determined is unresolved.

Shaping Giant Membrane Vesicles in 3D-Printed Protein Hydrogel Cages

open access: yes, 2020
Giant unilamellar phospholipid vesicles are attractive starting points for constructing minimal living cells from the bottom-up. Their membranes are compatible with many physiologically functional modules and act as selective barriers, while retaining a ...

3D Organisation of Cells in Pseudostratified Epithelia

open access: yesFrontiers in Physics, 2022
Pseudostratified epithelia have smooth apical and basal surfaces, yet along the apical-basal axis, cells assume highly irregular shapes, which we introduce as punakoids. They interact dynamically with many more cells than visible at the surface. Here, we

Transient increases in intracellular calcium and reactive oxygen species levels in TCam-2 cells exposed to microgravity [PDF]

open access: yes, 2017
The effects of microgravity on functions of the human body are well described, including alterations in the male and female reproductive systems. In the present study, TCam-2 cells, which are considered a good model of mitotically active male germ cells,
