Funkcija
[uredi | uredi izvor]Lahki lanac neurofilamenta je biomarker koji se može mjeriti imunološkim testovima u moždanokičmenoj tekućini i plazmi i odražava aksonsko oštećenje u raznim neurološkim poremećajima.[8][9] To je upotrebljiv marker za prećenje bolesti kao što je amiotrofna lateralna skleroza,[10] multipla skleroza[11] i Alzheimerova bolest,[12][13] a od nedavno i Huntingtonova bolest.[14] Veći broj povezan je s povećanjem mortaliteta.[15]
Povezan je s Charcot-Marie-Toothovim bolestima 1F i 2E.[5]

neuroaxonal damage is the pathological substrate of permanent disability in various neurological disorders. ... Here, we review what is known about the structure and function of neurofilaments, discuss analytical aspects and knowledge of age-dependent normal ranges of neurofilaments and provide a comprehensive overview of studies on neurofilament light chain as a marker of axonal injury in different neurological disorders, including multiple sclerosis, neurodegenerative dementia, stroke, traumatic brain injury, amyotrophic lateral sclerosis and Parkinson disease.

The very rapid neurodegeneration of prion disease results in strong signals from surrogate protein markers in the blood that reflect neuronal, axonal, synaptic or glial pathology in the brain: notably the tau and neurofilament light chain proteins.
