TAR DNA-binding protein 43 oligomers in physiology and pathology

TAR DNA-binding protein 43 (TDP-43) is an RNA/DNA-binding protein involved in RNA regulation and diseases. In 2006, TDP-43 inclusions were found in the disease lesions of several neurodegenerative diseases. It is the pathological hallmark in both amyotrophic lateral sclerosis and frontotemporal lobar dementia. It also presents in a large portion of patients with Alzheimer's disease. TDP-43 is prone to aggregate; however, the role of TDP-43 oligomers remains poorly understood in both physiological and pathological conditions. In this review, we emphasize the role of oligomeric TDP-43 in both physiological and pathological conditions and discuss the potential mechanisms of oligomer formation. Finally, we suggest therapeutic strategies against the TDP-43 oligomers in neurodegenerative diseases.

Automated summary

This review emphasizes the role of oligomeric TDP-43 in both physiological and pathological conditions and discusses the potential mechanisms of oligomer formation. By studying TDP-43 oligomers, we can gain a better understanding of their involvement in neurodegenerative diseases and provide new therapeutic strategies for these diseases.
