Summary of "Serum Neurofilament Chain Light as diagnostic biomarker for acute cerebral ischemia.Promising tool."

The search for serum markers to detect acute and chronic cerebral damage has become of vital importance in the clinical diagnosis and the monitoring of neurological diseases. In the past few years many studies have found an elevated Neurofilmant Light Chain (sNfL) level in the cerebrospinal fluid among patients with chronic neurodegenerative diseases,[1-3] the concentration of the aforementioned marker in the serum and cerebrospinal fluid has been found to be associated with acute nerve damage, particularly in the central nervous system.[4] This article is protected by copyright.

Serum Neurofilament Light Chain Levels as a Marker of Upper Motor Neuron Degeneration in Patients with Amyotrophic Lateral Sclerosis.

Amyotrophic Lateral Sclerosis (ALS) is the most common motor neuron degeneration disease with a diagnostic delay of about one year after symptoms onset. In ALS, blood neurofilament light chain (NfL) l...

The objective of this study is to test the feasibility of using serum neurofilament light chain (NfL) as a disease biomarker in Chemotherapy Induced Peripheral Neuropathy (CIPN) since this easy access...

Plasma neurofilament light as a potential biomarker of neurodegeneration in Alzheimer's disease.

A growing body of evidence suggests that the plasma concentration of the neurofilament light chain (NfL) might be considered a plasma biomarker for the screening of neurodegeneration in Alzheimer's di...

Serum neurofilament as a predictor of disease worsening and brain and spinal cord atrophy in multiple sclerosis.

Neuro-axonal injury is a key factor in the development of permanent disability in multiple sclerosis. Neurofilament light chain in peripheral blood has recently emerged as a biofluid marker reflecting...

Association of Plasma Neurofilament Light Chain with Neocortical Amyloid-β Load and Cognitive Performance in Cognitively Normal Elderly Participants.

The disruption of neurofilament, an axonal cytoskeletal protein, in neurodegenerative conditions may result in neuronal damage and its release into the cerebrospinal fluid and blood. In Alzheimer's di...

Medical and Biotech [MESH] Definitions

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.

An enzyme that phosphorylates myosin light chains in the presence of ATP to yield myosin-light chain phosphate and ADP, and requires calcium and CALMODULIN. The 20-kDa light chain is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors. The enzyme plays a central role in the regulation of smooth muscle contraction.

A heterodimeric protein that is a cell surface antigen associated with lymphocyte activation. The initial characterization of this protein revealed one identifiable heavy chain (ANTIGENS, CD98 HEAVY CHAIN) and an indeterminate smaller light chain. It is now known that a variety of light chain subunits (ANTIGENS, CD98 LIGHT CHAINS) can dimerize with the heavy chain. Depending upon its light chain composition a diverse array of functions can be found for this protein. Functions include: type L amino acid transport, type y+L amino acid transport and regulation of cellular fusion.

A transmembrane glycoprotein subunit that can dimerize with a variety of light chain subunits (ANTIGENS, CD98 LIGHT CHAINS). This protein subunit serves a diverse array of functions including amino acid transport and cell fusion. Its function is altered depending which of the light chain subunits it interacts with.
