Emergence of collective propulsion through cell-cell adhesion

, 2017
The mechanisms driving the collective movement of cells remain poorly understood. To contribute toward resolving this mystery, a model was formulated to theoretically explore the possible functions of polarized cell-cell adhesion in collective cell ...

Patterns of cell movement within the Dictyostelium slug revealed by cell type-specific, surface labeling of living cells [PDF]

, 1994
There are cells acattered in the rear, prespore region of the Dictyostelium slug that share many of the properties of the prestalk cells and that are therefore called anterior-like cells (ALCs).

Cell-to-cell stimulation of movement in nonmotile mutants of Myxococcus [PDF]

Proceedings of the National Academy of Sciences, 1977
A large number of nonmotile mutants of the gliding bacterium Myxococcus xanthus have been isolated and partly characterized. About [unk] of these mutants are conditional mutants of a novel kind: mutant cells become transiently motile after contact with nonmutant cells or with cells of a different mutant type. These “

HSP70 homolog functions in cell-to-cell movement of a plant virus [PDF]

Proceedings of the National Academy of Sciences, 1999
Plant closteroviruses encode a homolog of the HSP70 (heat shock protein, 70 kDa) family of cellular proteins. To facilitate studies of the function of HSP70 homolog (HSP70h) in viral infection, the beet yellows closterovirus (BYV) was modified to express green fluorescent protein.

A framework for quantification and physical modeling of cell mixing applied to oscillator synchronization in vertebrate somitogenesis [PDF]

, 2017
In development and disease, cells move as they exchange signals. One example is found in vertebrate development, during which the timing of segment formation is set by a ‘segmentation clock’, in which oscillating gene expression is synchronized across a ...

Cell Segmentation and Tracking using CNN-Based Distance Predictions and a Graph-Based Matching Strategy [PDF]

, 2020
The accurate segmentation and tracking of cells in microscopy image sequences is an important task in biomedical research, e.g., for studying the development of tissues, organs or entire organisms.

A coiled-coil interaction mediates cauliflower mosaic virus cell-to-cell movement [PDF]

Proceedings of the National Academy of Sciences, 2005
The function of the virion-associated protein (VAP) of cauliflower mosaic virus (CaMV) has long been only poorly understood. VAP is associated with the virion but is dispensable for virus morphogenesis and replication. It mediates virus transmission by aphids through simultaneous interaction with both the aphid transmission factor and the virion ...

Broad bean wilt virus 2 movement protein VP37 relocalizes the host co-chaperone HOP from the nucleus to plasmodesmata to promote viral intercellular movement

Plant Stress
Plant viruses exploit host cellular machinery to fold, stabilize, and target their movement proteins (MPs) to plasmodesmata (PD), enabling viral cell-to-cell and systemic spread.

Tubule-guided cell-to-cell movement of a plant virus requires class XI myosin motors. [PDF]

PLoS Pathogens, 2011
Cell-to-cell movement of plant viruses occurs via plasmodesmata (PD), organelles that evolved to facilitate intercellular communications. Viral movement proteins (MP) modify PD to allow passage of the virus particles or nucleoproteins.

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.
