Slow vs fast axonal transport
Webb31 juli 2024 · Slow axonal transport (SAT) moves multiple proteins from the soma, where they are synthesized, to the axon terminal. Due to the great lengths of axons, SAT almost exclusively relies on active transport, which is driven by molecular motors. The puzzling feature of slow axonal transport is its bidirectionality. Vesicular cargoes move relatively fast (50–400 mm/day) whereas transport of soluble (cytosolic) and cytoskeletal proteins takes much longer (moving at less than 8 mm/day). The basic mechanism of fast axonal transport has been understood for decades but the mechanism of slow axonal transport is only … Visa mer Axonal transport, also called axoplasmic transport or axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron Visa mer The vast majority of axonal proteins are synthesized in the neuronal cell body and transported along axons. Some mRNA translation has been demonstrated within axons. Axonal transport occurs throughout the life of a neuron and is essential to its growth and survival. Visa mer Whenever axonal transport is inhibited or interrupted, normal physiology becomes pathophysiology, and an accumulation of axoplasm, called an axonal spheroid, may result. Because … Visa mer The rabies virus reaches the central nervous system by retrograde axoplasmic flow. The tetanus neurotoxin is internalised at the neuromuscular junction through binding the nidogen proteins and is retrogradely transported towards the soma in signaling … Visa mer Anterograde (also called "orthograde") transport is movement of molecules/organelles outward, from the cell body (also called soma) to the synapse or Visa mer Retrograde transport shuttles molecules/organelles away from axon termini toward the cell body. Retrograde axonal transport is mediated by cytoplasmic dynein, and is used for example to send chemical messages and endocytosis products … Visa mer • Intraflagellar transport Visa mer

WebbWhereas fast transport delivers vesicular cargoes, slow transport carries cytoskeletal and cytosolic (or soluble) proteins that have critical roles in neuronal structure and function. Although significant progress has been made in dissecting the molecular mechanisms of fast vesicle transport, mechanisms of slow axonal transport are less clear. WebbThe proteins kinesin and dynein are involved in the transport process along neurotubules, and the speed of transport is sometimes divided into two types: fast and slow. 'Fast axonal transport' is extremely slow compared …
