Neurofilament is a type of protein that plays a crucial role in the structure and function of neurons. It is a key component of the axons of neurons and is found in the cytoskeleton, which provides the framework for these long, thin extensions of the cell. Neurofilaments are composed of three subunits, light, medium, and heavy, which are encoded by different genes.

Research has demonstrated that neurofilaments are involved in the maintenance of axonal diameter, preventing the collapse and degeneration of axons. They also play a role in regulating the velocity of axonal transport, the movement of proteins and other materials along axons. Additionally, neurofilaments have been implicated in the regulation of signaling pathways within neurons, influencing synaptic plasticity and learning and memory.

Abnormalities in neurofilament genes, particularly the heavy neurofilament subunit gene, have been linked to neurodegenerative diseases such as Amyotrophic Lateral Sclerosis (ALS). In these conditions, the absence of functional neurofilaments can lead to symptoms including muscle weakness, atrophy, and spasticity. Research has also implicated neurofilament in neuroprotection, with potential therapeutic applications in treating neurodegenerative diseases.

The protein can be detected in the cerebrospinal fluid, a valuable diagnostic tool for monitoring neurodegenerative diseases. Measurements of neurofilament levels in the cerebrospinal fluid have been correlated with disease progression and cognitive decline in conditions such as Alzheimer's disease and Parkinson's disease. Overall, neurofilaments play a vital role in maintaining neuronal health and are the subject of ongoing research aimed at understanding their function in health and disease.
