Understanding the molecular pathogenesis of neurodegenerative diseases: towards the development of effective therapeutic agents for the treatment of ALS and other neurodegenerative diseases

Amyotrophic lateral sclerosis (ALS) is a heterogeneous group of incurable motor neuron diseases (MNDs) characterized by a selective loss of upper and lower motor neurons in the brain and spinal cord.

In 2001, we have identified ALS2 as a causative gene for a recessive type of familial ALS. The ALS2 gene encodes ALS2 (or alsin) that is implicated in axonal outgrowth, cytoprotection from oxidative stress, and proteostasis by regulating the autophagy-endlysoosomal system. However, our understanding of the intricate autophagy-endolysosomal system and its functional linking to other physiological systems in the CNS is still immature.

In our lab, to uncover the molecular mechanisms of a selective neurodegeneration, we are currently focusing on the autophagy-lysosomal and endocytic degradation systems, and implication of their dysfunction to the pathogenesis of ALS/MNDs. Ultimately, through these studies, we aim to develop effective therapeutic agents for the treatment of ALS/MNDs and other neurodegenerative diseases.
