Motor Neurone Disease Group

Neurodegenerative diseases have a devastating impact on quality of life and impose a tremendous burden on the health care system. Motor neurone disease (MND) is the most rapidly fatal, with increasing physical disability and death typically within 2-3 years from symptom onset.

Our group has a broad interest in developing and delivering new therapeutics for MND using pioneering stem cell and animal models.

About our research

Our group is primarily focused on understanding the molecular basis of motor neurone disease (MND), also called amyotrophic lateral sclerosis (ALS), to inform rational drug development for treatment. We also research other neurodegenerative diseases affecting motor neurons, including spinal muscular atrophy (SMA) and spinal bulbar muscular atrophy (SBMA), more commonly known as Kennedy’s disease (KD).

Key research questions

  • What is the fundamental cause of ALS?
  • When does motor neuron vulnerability start in ALS?
  • Where does ALS originate in the central nervous system?
  • What is the primary cell death pathway(s) mediating motor neuron loss in ALS?
  • How early do we need to intervene with treatments in ALS?
  • Do ALS, SMA and KD share a common pathogenesis?

Research interests

  • Motor neurone disease (MND)
  • Amyotrophic lateral sclerosis (ALS)
  • Primary lateral sclerosis (PLS)
  • Spinal muscular atrophy (SMA)
  • Kennedy’s disease (KD)
  • Frontotemporal dementia (FTD)

Our approach

Our team employs a combination of cell and molecular biology to unravel MND pathogenesis in patient-derived biosamples, cell culture systems and animal models.  We seek to identify and understand the primary mechanisms underlying motor neuron vulnerability and degeneration in MND, while translating our discoveries into relevant targets for effective intervention. Our group is particularly known for pioneering new and improved models of MND using induced pluripotent stem cell (iPSC) technology, organoids, chemogenetics and genome editing.

Our major outcomes

  • Establishing a large-scale, population-wide library of induced pluripotent stem cells (iPSCs) from Australian MND patients pre-validated for disease phenotypes and drug efficacy (ID MND Initiative).
  • Establishing a multi-omic dataset from Australian MND patient iPSC-derived motor neurons combining deep longitudinal clinical, genomic, transcriptomic and metabolomic profiles to understand heterogeneity (Precision Medicine Program).
  • Our preclinical findings have directly contributed to 5 clinical trials for MND, including re-purposing of the generic drug ambroxol for ALS which is currently under Phase 2 clinical trial.
