Neurons: The Axon

Neurons: The Axon

Axons are long, cytoplasmic processes of nerve cells capable of propagating electrical impulses known as action potentials. The cytoplasm or axoplasm of an axon contains neurofibrils, neurotubules, small vesicles, lysosomes, mitochondria, and various enzymes, all encased within the axolemma, the plasma membrane of the axon.
The axon attaches to the cell body at a cone-shaped elevation called the axon hillock. The initial part of the axon, closest to the hillock, is known as the initial segment....

Natural and Artificial Concepts

Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Heat Engines

Heat Engines

A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

Internal Combustion Engine

Internal Combustion Engine

The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Synaptic Signaling

Synaptic Signaling

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Background:

Myelination is essential for neuronal signaling, survival, and nervous system function.
Myelin disorders, including multiple sclerosis, significantly impact neurological health.
Current in vitro models are limited for studying myelination and developing remyelination therapies.

Purpose of the Study:

To develop a novel experimental platform for studying myelination in vitro.
To investigate the influence of physical and chemical cues on oligodendrocyte behavior and myelin formation.
To create biofidelic synthetic axon mimics for observing myelination processes.

Main Methods:

Fabrication of synthetic axon mimics using 3D printing technology.
Mimics replicate key geometric, mechanical (low stiffness), and surface chemistry properties of biological axons.
Utilized the platform to study oligodendrocyte interaction and myelin production in response to varying axon properties.

Main Results:

Oligodendrocyte myelination (production and wrapping) is dependent on the stiffness, diameter, and ligand coating of the artificial axons.
The synthetic platform allows for direct visualization and quantification of myelin formation.
Demonstrated the ability to assess myelinating cell responses to physical cues and pharmacological agents.

Conclusions:

The developed biofidelic artificial axon platform enables in-depth study of myelination processes.
This model provides new insights into how physical axon properties regulate myelin formation.
The platform holds potential for advancing the development of effective remyelination therapies for neurological diseases.
