Movement proteins (MPs) are virally encoded factors that mediate transport of viral nucleic acid between plant cells. Many MPs are able to move between cells themselves. This feature serves as the basis for evaluation of the transport activity of individual MPs.

Cyclic GMP and Cell Movement [PDF]
Nature, 1973 THE movement of mammalian cells can be inhibited by agents which mimic or produce increases in the intracellular levels of cyclic 3′,5′-adenosine monophosphate (cyclic AMP)1,2. Goldberg and coworkers3,4 have proposed that in a number of cell types cyclic 3′,5′-guanosine monophosphate (cyclic GMP) promotes cellular events that are antagonistic to those ...

Nuclear movement in multinucleated cells
Development, 2022ABSTRACTNuclear movement is crucial for the development of many cell types and organisms. Nuclear movement is highly conserved, indicating its necessity for cellular function and development. In addition to mononucleated cells, there are several examples of cells in which multiple nuclei exist within a shared cytoplasm.

T-cell movement on the reticular network
Journal of Theoretical Biology, 2012The idea that the apparently random motion of T cells in lymph nodes is a result of movement on a reticular network (RN) has received support from dynamic imaging experiments and theoretical studies. We present a mathematical representation of the RN consisting of edges connecting vertices that are randomly distributed in three-dimensional space, and ...

SIMULATION OF CELL MOVEMENT AND INTERACTION
Journal of Bioinformatics and Computational Biology, 2011A mechanical model of cell motion was developed that reproduced the behaviour of cells in 2-dimensional culture. Cell adhesion was modelled with inter-cellular cross-links that attached for different times giving a range of adhesion strength. Simulations revealed an adhesion threshold below which cell motion was almost unaffected and above which cells

Kinesin Assembly and Movement in Cells
Annual Review of Biophysics, 2011Long-distance transport in eukaryotic cells is driven by molecular motors that move along microtubule tracks. Molecular motors of the kinesin superfamily contain a kinesin motor domain attached to family-specific sequences for cargo binding, regulation, and oligomerization.

Structure and Movement in Cells [PDF]
, 1983 In this introductory chapter I will review basic cellular processes and structures, emphasising the dynamic activity inherent in these biological systems. Our present knowledge of biological structure and functional activity derives from two distinct approaches, structural studies, made on living material in the light microscope and preserved material ...

Caspases are well known for their roles in programmed cell death and for their roles in maturation of inflammatory cytokines. Li et al . now show that caspase 11 also has a role in regulating actin dynamics that contributes to cell migration.

During embryological development cells undergo carefully coordinated movements which, if carried out correctly, will result in the formation of tissues and organs. These morphogenetic movements can be classified as migratory, elongating, folding, or “passive” movements.*

Tracking Movement in Cell Biology
2005This article is an overview of techniques for measuring movement of proteins, vesicles and cells using digital image processing. Diverse techniques have been developed during the last decade. Both strong and weak points of each technique are discussed, together with short description on the actual application.
