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 “

Exosomes released from breast cancer carcinomas stimulate cell movement [PDF]

, 2015
For metastasis to occur cells must communicate with to their local environment to initiate growth and invasion. Exosomes have emerged as an important mediator of cell-to-cell signalling through the transfer of molecules such as mRNAs, microRNAs, and ...

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 ...

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 ...

On the mechanical interplay between intra- and inter-synchronization during collective cell migration : a numerical investigation [PDF]

, 2013
Collective cell migration is a fundamental process that takes place during several biological phenomena such as embryogenesis, immunity response, and tumorogenesis, but the mechanisms that regulate it are still unclear.

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.

Statistical inference of the mechanisms driving collective cell movement [PDF]

, 2017
Numerous biological processes, many impacting on human health, rely on collective cell movement. We develop nine candidate models, based on advection-diffusion partial differential equations, to describe various alternative mechanisms that may drive ...

Cytorhabdovirus P3 genes encode 30K-like cell-to-cell movement proteins

Virology, 2016
Plant viruses encode movement proteins (MP) to facilitate cell-to-cell transport through plasmodesmata. In this study, using trans-complementation of a movement-defective turnip vein-clearing tobamovirus (TVCV) replicon, we show for the first time for cytorhabdoviruses (lettuce necrotic yellows virus (LNYV) and alfalfa dwarf virus (ADV)) that their P3 ...
