Our previous findings have demonstrated evidence of astrocytic and axonal injury in the acute phase of COVID-19 by analysing glial fibrillary acidic protein (GFAp), a major structural protein in the astroglial cytoskeleton and a biomarker of astrocytic activation/injury [6], and neurofilament light chain (NfL), an intra-axonal structural protein and a biomarker of neuronal injury [7]. This evidence concerns the gene NEFL and COVID-19.
