In this sense, proteins such as β-III tubulin (microtubule of dendrites and axons), neurofilament light chain (Nf-L) (structural protein exclusive of neurons), and glial fibrillary acidic protein (GFAP) (structural component of astrocytal cytoskeleton) which are associated with neurodegenerative diseases such as Alzheimer or amyotrophic lateral sclerosis (ALS)38–41 may have a substantial role in SZ. Here, NEFL is linked to neurodegenerative disease.
