Pathophysiological processes in multiple sclerosis frequently not diagnosed by clinicians become available for analysis only on the basis of paraclinical data (biomarkers). Nowadays neurofilament light chain can be defined as a promising biomarker for multiple sclerosis (MS). Neurofilaments are a structural part of normal neuronal processes consisting of light, intermediate and heavy chains. However, a damage of neurons such as neurodegeneration or axonal damage causes the escape of neurofilaments into extracellular space. Cutting-edge highly sensitive methods make it possible to detect neurofilament light chains not only in the cerebrospinal fluid but also in the blood serum thus opening the opportunities to utilize them in routine diagnosis in clinical practice. This review comprises existing data on the possible opportunities for research of serum neurofilament light chains in terms of exacerbations, effectiveness of basic therapy, assessment of individual disability, the atrophy of central nervous system structures. Also, there is some information on comparison of two methods: routine MRI of the brain with the contrast agents and detection of serum neurofilament light chains.

To determine whether serum phosphorylated neurofilament heavy chain (pNfH) levels are elevated before patients were diagnosed with sporadic or familial ALS, and what the prognostic value of these pred...
Gray matter (GM) pathology is closely associated with physical and cognitive impairment in persons with multiple sclerosis (PwMS). Similarly, serum neurofilament light chain (sNfL) levels are related ...
The prognostic value of serum neurofilament light chain (sNfL), a biomarker of neurodegeneration, compared to other prognostic factors of amyotrophic lateral sclerosis (ALS) at the time of diagnosis, ...
To test the hypothesis that serum levels of glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL), which are an intermediate astrocyte and neuron filaments, respectively, are clin...
Neurofilament light chain (NfL) is a marker of neuroaxonal damage. We aimed to study associations between serum NfL (sNfL) concentrations at different time points after ischemic stroke and outcomes.
The investigators hypothesize that serum neurofilament-light chain (NfL) levels can provide information about the level of activity and progression of Multiple Sclerosis at different stage...

Type III intermediate filament proteins that assemble into neurofilaments, the major cytoskeletal element in nerve axons and dendrites. They consist of three distinct polypeptides, the neurofilament triplet. Types I, II, and IV intermediate filament proteins form other cytoskeletal elements such as keratins and lamins. It appears that the metabolism of neurofilaments is disturbed in Alzheimer's disease, as indicated by the presence of neurofilament epitopes in the neurofibrillary tangles, as well as by the severe reduction of the expression of the gene for the light neurofilament subunit of the neurofilament triplet in brains of Alzheimer's patients.

Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.
The smaller subunits of MYOSINS that bind near the head groups of MYOSIN HEAVY CHAINS. The myosin light chains have a molecular weight of about 20 KDa and there are usually one essential and one regulatory pair of light chains associated with each heavy chain. Many myosin light chains that bind calcium are considered "calmodulin-like" proteins.
A pyrrole and heptanoic acid derivative,HYDROXYMETHYLGLUTARYL-COA REDUCTASE INHIBITOR (statin), and ANTICHOLESTEREMIC AGENT that is used to reduce serum levels of LDL-CHOLESTEROL; APOLIPOPROTEIN B; AND TRIGLYCERIDES and to increase serum levels of HDL-CHOLESTEROL in the treatment of HYPERLIPIDEMIAS and prevention of CARDIOVASCULAR DISEASES in patients with multiple risk factors.
A tetrameric protein, molecular weight between 50,000 and 70,000, consisting of 4 equal chains, and migrating on electrophoresis in 3 fractions more mobile than serum albumin. Its concentration ranges from 7 to 33 per cent in the serum, but levels decrease in liver disease.
Spinal Cord Disorders
The spinal cord is a bundle of nerves that runs down the middle of the back which carry signals back and forth between the body and brain. It is protected by vertebrae, which are the bone disks that make up the spine. An accident that damages the verte...
