2023
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Anterograde amnesia is the loss of the ability to form new memories. This can be distinguished from retrograde amnesia, which is the loss of old memories. Anterograde amnesia can result from damage to structures in the brain that are involved in the formation of new memories. Patients who have damage to the structures of the medial temporal lobe, including the hippocampus, amygdala, and the surrounding...

Source: Keefe, K. M., et al. Direct Injection of a Lentiviral Vector Highlights Multiple Motor Pathways in the Rat Spinal Cord. J. Vis. Exp. (2019).This video demonstrates the injection of a highly efficient retrograde transport (HiRet) viral vector into the rat spinal cord to trace neuronal pathways. The virus has glycoproteins for synaptic entry and a fluorescent protein coding gene. The needle is inserted into the spinal cord, and the virus suspension is administered at a controlled rate.
FAQs
Their coordination links the cell body with distant synaptic terminals in both directions. Outward delivery supplies terminals with newly synthesized proteins, membrane components, and organelles, while inward return brings signaling endosomes, recycled materials, and damaged components back toward the cell body. Maintaining this exchange supports synaptic function, neuronal survival, and appropriate responses to axonal injury.
Kinesin and dynein provide the directional motor activities, while polarized microtubules serve as the intracellular tracks. Both motors use ATP to travel along those tracks, allowing cargo to move either outward or inward through the axon. Studying this arrangement helps explain how neurons maintain long cellular extensions despite the distance between their cell bodies and synaptic terminals.
Cargo identity reflects the direction and functional purpose of transport. Anterograde movement carries newly synthesized proteins, membrane components, and organelles toward synaptic terminals. Retrograde movement returns signaling endosomes, recycled materials, and damaged components toward the cell body. Comparing these cargo groups helps investigators connect intracellular trafficking with synaptic maintenance, recycling, signaling, and cellular quality control.
Researchers can examine which materials move toward synaptic terminals and which return toward the cell body, then relate those movements to the motors and microtubule polarity involved. This approach connects cargo distribution with neuronal maintenance and signaling. It also provides a framework for investigating how transport changes during axonal injury or in conditions associated with neurodegenerative disease.
The system is especially relevant when researchers investigate axonal maintenance, intracellular signaling, neurodegenerative disease mechanisms, or responses to injury. Because axons connect cell bodies with distant terminals, altered movement can affect the delivery, return, and handling of essential materials. Studying both directions therefore helps relate cellular trafficking to broader neuronal survival and communication.
Axonal transport can serve as a way to trace neural connections because materials move along the axon between the cell body and synaptic terminals. By studying the direction of movement, investigators can relate transported material to the organization of neuronal pathways. This application extends the study of intracellular trafficking beyond cell maintenance to the mapping of neural connectivity.
