WebMar 7, 2024 · Phosphorylated neurofilament heavy chain (pNfH) is a cytoskeletal structural protein released as a result of axonal damage into the cerebrospinal fluid (CSF), and subsequently into the blood. Due to high specificity for neuronal cell damage, pNfH is advantageous over other biomarkers, for ALS disease identification. WebThe ability of these polymers to bear mechanical tension and compression allows them to form and stabilize cellular architecture and generate cell movements, and their long length allows them to serve as tracks for the movement of intracellular cargoes. lamar odom bunny ranch
