TDP-43 (TAR DNA-binding protein 43) has been identified as a key protein of ubiquitinated inclusions in brains of patients with ALS (amyotrophic lateral sclerosis) or FTLD (frontotemporal lobar degeneration), defining a new pathological disease spectrum. Recently, coding mutations have been identified in the TDP-43 gene (TARDBP), which further confirmed the pathogenic nature of the protein. Today, several animal models have been generated to gain more insight into the disease-causing pathways of the FTLD/ALS spectrum. This mini-review summarizes the current status of TDP-43 models, with a focus on mutant TDP-43.
