A major aim in MS field has been the search for biomarkers that enable accurate detection of neuronal damage. Besides MRI, recent studies have shown that neuroaxonal damage can also be tracked by neurofilament detection. Nevertheless, before widespread implementation, a better understanding of the principal contributors for this biomarker is of paramount importance. Therefore, we analyzed neurofilament light chain (NfL) in relapsing (RMS) and progressive MS (PMS), addressing which MRI and clinical variables are better related to this biomarker.

Systematic evaluation of biomarkers in representative populations is needed to validate their clinical utility. In this work, we assessed the diagnostic performance of cerebrospinal fluid neurofilamen...
The effect of vitamin D supplementation on the disease course of multiple sclerosis (MS) is not established. Neurofilament light chain (NFL) is a sensitive marker of axonal degeneration. The aim of th...
Central nervous system (CNS) inflammatory demyelinating disease (IDD) is an immune-mediated disease that is pathologically characterized by demyelination and inflammatory infiltration in the CNS and i...
Neurofilament light (NFL) is a well-validated biomarker for neuronal injury and neurodegeneration. Increased cerebrospinal fluid (CSF) levels have been shown after stroke, as well as in patients with ...
Multiple sclerosis (MS) is a chronic central nervous system immune-mediated disease with an important inflammatory component associated with focal demyelination and widespread neurodegeneration. In mo...
The purpose of this study is to investigate if B vitamin substitution have effect on NFL (neurofilament light protein) plasma levels and neurocognitive performance in HIV-infected individu...
This study will include patients with previously treated systemic relapsed or refractory light-chain (AL) amyloidosis who require further therapy and will be aimed at determining the safet...
The study is an investigator-run, open-label Phase 1 safety study of autologous mesenchymal stem cell transplantation, involving approximately 24 participants with relapsing forms of MS (a...

The purpose of this study is to determine efficacy of lenalidomide and dexamethasone in the treatment of patients with acute Myeloma (light chain)-induced renal failure.
A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form.

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.
Rare autosomal recessive disorder of INTERMEDIATE FILAMENT PROTEINS. The disease is caused by mutations in the gene that codes gigaxonin protein. The mutations result in disorganization of axonal NEUROFILAMENT PROTEINS, formation of the characteristic giant axons, and progressive neuropathy. The clinical features of the disease include early-onset progressive peripheral motor and sensory neuropathies often associated with central nervous system involvement (mental retardation, seizures, DYSMETRIA, and CONGENITAL NYSTAGMUS).
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Multiple Sclerosis MS
Multiple sclerosis (MS) is the most common disabling neurological condition affecting 100,000 young adults in the UK. The condition results from autoimmune damage to myelin, causing interference in nerve signaling. Symptoms experienced depend on the pa...
