Spontaneous signal generation by an excitable system for cell migration

open access: yesFrontiers in Cell and Developmental Biology
Eukaryotic cells exhibit random migration in the absence of extracellular directional cues. This random migration acts as basal motility for various migratory responses such as chemotaxis.

A mobile endocytic network connects clathrin-independent receptor endocytosis to recycling and promotes T cell activation

open access: yesNature Communications, 2018
Endocytosis of T cell receptors (TCR) and their polarized recycling back to the plasma membrane is crucial for T cell activation; however, the underlying mechanisms remain unclear.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Microscopic simulation of membrane molecule diffusion on corralled membrane surfaces [PDF]

open access: yes, 2008
The current understanding of how receptors diffuse and cluster in the plasma membrane is limited. Data from single-particle tracking and laser tweezer experiments have suggested that membrane molecule diffusion is affected by the presence of barriers ...

Surface plasmon driven atomic migration mediated by molecular monolayer

open access: yesPhotoniX
Highly efficient controlling the individual atomic migration is the basis of the modern atomic manufacturing. Although one-by-one atom migration can be realized precisely by STM technique, such a delicate operation is time consuming and restrictive ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Single Molecule Force Extension Measurement on Semi-Flexible Biopolymers Using Magnetic Tweezers [PDF]

open access: yes, 2010
Polymers are pervasive in modern society and are commonly encountered in a wide-range of industrial processes. Polymer chains exhibit complex dynamical phenomena in solutions undergoing convective transport, and a proper understanding of chain dynamics ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
