Classification of HEp-2 Staining Pattern Images Using Adapted Multilayer Perceptron Neural Network-Based Intra-Class Variation of Cell Shape

Sensors, 2023
There exists a growing interest from the clinical practice research communities in the development of methods to automate HEp-2 stained cells classification procedure from histopathological images.

Tight Regulation of Mechanotransducer Proteins Distinguishes the Response of Adult Multipotent Mesenchymal Cells on PBCE-Derivative Polymer Films with Different Hydrophilicity and Stiffness

Cells, 2023
Mechanotransduction is a molecular process by which cells translate physical stimuli exerted by the external environment into biochemical pathways to orchestrate the cellular shape and function.

Getting bacterial cells into shape

eLife, 2023
The conformational state of a structural protein in bacteria can vary, depending on the concentration level of potassium ions or the nucleotide bound to it.

Effect of Sintering Temperature and Applied Load on Anode-Supported Electrodes for SOFC Application

Energies, 2016
Anode-supported cells are prepared by a sequence of hot pressing and co-sintering processes for solid oxide fuel cell (SOFC) applications. Commercially available porous anode tape (NiO/YSZ = 50 wt %/50 wt %), anode tape (NiO/YSZ = 30 wt %/70 wt %), and ...

Insights Into the Helical Shape Complex of Helicobacter pylori

Frontiers in Microbiology, 2022
One important factor that promotes the colonization of the upper digestive system of the human pathogen Helicobacter pylori is its helical cell shape. The bacteria cell shape is predominantly defined by its peptidoglycan cell wall. In rod-shaped species,

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

Frontiers 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 ...

Shaping the T cell repertoire [PDF]

The Journal of Immunology, 2005
Today immunologists are well aware of positive and negative selection of developing T cells. This was very different almost three decades ago when MHC-restricted Ag recognition by T cells represented an enormous puzzle in the absence of data on the molecular nature of Ag recognition by T cells ...

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

Cell 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 ...

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

mBio
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

eLife, 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.
