Imaging-derived mean square displacement (iMSD) analysis is applied to macropinosomes to highlight their intrinsic time-evolving nature in terms of structural and dynamic properties. Macropinosomes are then compared to insulin secretory granules (ISGs) as a reference for subcellular structures with time-invariant average structural/dynamic properties.

We describe a modified method for membrane fraction isolation from human cells and sample preparation for the detection of SCAP N-glycosylation and total protein by using western blot. We further introduce a GFP-labeling method to monitor SCAP trafficking using confocal microscopy. This protocol can be used in regular biology laboratories.

Recently available video recording and spatiotemporal mapping (STmap) techniques make it possible to visualize and quantify both propagating and mixing patterns of intestinal motility. The goal of this protocol is to explain the generation and analysis of STmaps using the GastroIntestinal Motility Monitoring (GIMM) system.

While the transport of cell surface proteins is relatively easily studied, visualizing the trafficking of intracellular proteins is much more difficult. Here, we use constructs incorporating photoactivatable GFP and demonstrate a method to accurately follow the amyloid precursor protein from the Golgi apparatus to down-stream compartments and follow its clearance.
FAQs
Signaling pathways coordinate several stages of cargo handling rather than simply initiating movement. They influence route selection, docking at the destination, membrane fusion, and turnover of transported material. This regulation allows delivery to occur at an appropriate cellular location and time, supporting changing demands in axons, dendrites, and synapses.
Motor proteins move sorted transport carriers and organelles along microtubules or actin filaments. These cytoskeletal tracks provide the routes that connect different cellular regions, while carrier sorting helps determine which materials enter transport. Together, these components organize delivery within the extended architecture of a neuron.
Arrival alone does not ensure that cargo becomes functional. Docking positions a carrier at its target site, and fusion enables the transported material to be delivered there. Regulated turnover then helps remove or replace material as needed. These steps are particularly important for maintaining receptor recycling and neurotransmitter release at synapses.
Studies can examine cargo dynamics in living neural cells by focusing on where molecules, vesicles, or organelles move, when delivery occurs, and how route selection, docking, fusion, or turnover changes. Measurement and manipulation of these dynamics can connect intracellular transport behavior with neuronal organization and synaptic activity.
Coordinated trafficking contributes to axon growth, dendritic organization, neurotransmitter release, and receptor recycling at synapses. These outcomes require materials to reach appropriate neuronal regions and to be handled at suitable times. Examining cargo movement therefore helps relate intracellular transport to both structural development and communication between neurons.
Transport defects can disrupt the delivery and handling of molecules, vesicles, or organelles in neural cells. Because trafficking supports axon growth, dendritic organization, neurotransmitter release, and receptor recycling, altered cargo dynamics may help researchers connect intracellular abnormalities with neurodevelopmental disorders and neurodegenerative disease, while guiding strategies to measure or manipulate transport.
