The transport and assembly of the axonal cytoskeleton
ERV~ cells display a number of unusual properties which are generally viewed as adaptations to their extreme length and regional specialization. The dense and highly organized neurofilament (NF) ~ and microtubule (MT) arrays which serve to support nerve axons provide one example; another is the phenomenon of axonal transport, by which macromolecules synthesized in the cell body move outward alo...
متن کاملSpatial Cytoskeleton Organization Supports Targeted Intracellular Transport.
The efficiency of intracellular cargo transport from specific sources to target locations is strongly dependent upon molecular motor-assisted motion along the cytoskeleton. Radial transport along microtubules and lateral transport along the filaments of the actin cortex underneath the cell membrane are characteristic for cells with a centrosome. The interplay between the specific cytoskeleton o...
متن کاملThe cytoskeleton in plasmodesmata: a role in intercellular transport?
Actin and myosin are components of the plant cell cytoskeleton that extend from cell to cell through plasmodesmata (PD), but it is unclear how they are organized within the cytoplasmic sleeve or how they might behave as regulatory elements. Early work used antibodies to locate actin and myosin to PD, at the electron microscope level, or to pitfields (aggregations of PD in the cell wall), using ...
متن کاملPlasmodesmata and intercellular transport of viral RNA.
Cell-to-cell communication in plants involves the symplastic trafficking of informational protein and RNA macromolecules through cytoplasmic bridges in the plant cell wall known as plasmodesmata. Viruses exploit this route for the spread of infection and are used as a model to study the mechanisms by which macromolecules are targeted to the pore. Studies using tobacco mosaic virus have led to t...
متن کاملCellular Cytoskeleton Dynamics Modulates Non-Viral Gene Delivery through RhoGTPases
Although it is well accepted that the constituents of the cellular microenvironment modulate a myriad of cellular processes, including cell morphology, cytoskeletal dynamics and uptake pathways, the underlying mechanism of how these pathways influence non-viral gene transfer have not been studied. Transgene expression is increased on fibronectin (Fn) coated surfaces as a consequence of increase...
