Neurofilament - Wikipedia
Neurofilaments (NF) are classed as type IV intermediate filaments found in the cytoplasm of neurons. They are protein polymers measuring 10 nm in diameter and many micrometers in length. [1] . Together with microtubules (~25 nm) and microfilaments (7 nm), they form the neuronal cytoskeleton.
Neurofibrils - an overview | ScienceDirect Topics
Neurofibrils. Neurofibrils are best seen in large neurons, but are present in almost all (Fig. 21G). With metallic-impregnation, they are thin, interlacing, silver-loving threads (up to 2 μm in diameter) running through the cytoplasm and extending into dendrites and axon.
Neurofilaments: Properties, Functions, and Regulation
2012年1月1日 · Neuronal intermediate filaments are the most prominent cytoskeleton component of adult neurons in both central and peripheral nervous system. They include neurofilament triplet proteins, peripherin, α-internexin, nestin, and synemin.
Neurofilaments at a glance - PMC
Neurofilaments from the central nervous system (CNS) are heteropolymers that are composed of four subunits, namely neurofilament heavy, medium and light polypeptides (NFH, NFM and NFL, respectively; also known as NEFH, NEFM and NEFL), as well as α-internexin (Int), whereas in the peripheral nervous system, neurofilaments are made up of NFH, NFM,...
Neurofilaments: neurobiological foundations for biomarker …
Gafson et al. review the neurobiology of neurofilament proteins, including their role in synapses and their contributions to disease pathogenesis, before evaluating the evidence supporting the use of neurofilament concentration measures as biomarkers of neurodegeneration.
Neurofilaments in disease: what do we know? - PMC
Neurofilaments are proteins selectively expressed in the cytoskeleton of neurons, and increased levels are a marker of damage. Elevated neurofilament levels can serve as a marker of ongoing disease activity as well as a tool to measure response to therapeutic intervention.
Neurofibrillary Pathology: An Update | SpringerLink
Neurofibril is the term coined by light microscopists to refer to the fibrillary structures in the neuron. These neurofibers correspond to a variety of linear structures as seen with the electron microscope. The principal fibrils of the normal mature neuron are the neurotubules and the neurofilaments (Fig. 1).

Neurofilaments: A Review and Update | SpringerLink
For decades neuroanatomists have been familiar with a distinctive fibrillar appearance of large mammalian axons after treatment of nervous tissue with various silver stains. These structures were aptly referred to as “neurofibrils.”
