Lymphoblastoid cell lines as a model to understand amyotrophic lateral sclerosis disease mechanisms.

ABSTRACT: In the past, amyotrophic lateral sclerosis (ALS) has been considered a 'neurocentric' disease; however, new evidence suggests that it should instead be looked at from a 'multisystemic' or 'non-neurocentric' point of view. From 2006, we focused on the study of non-neural cells: ALS patients' peripheral blood mononuclear cells (PMBCs) and lymphoblastoid cell lines (LCLs). Here, we characterize LCLs of sporadic ALS (sALS) and patients carrying SOD1, TARDBP and FUS mutations to identify an ALS biologically relevant molecular signature, and determine whether and how mutations differentially affect ALS-linked pathways. Although LCLs are different from motor neurons (MNs), in LCLs we found some features typical of degenerating MNs in ALS, i.e. protein aggregation and mitochondrial dysfunction. Mo
