Neurodegenerative Diseases Group: Prof Gilles Guillemin, Ph.D. Chai Kiat (Edwin) Lim, Ph.D

Prof Guillemin’s team is one of the world’s leading research groups studying neuroactive (toxic or protective or immunomodulator) metabolites derived from tryptophan metabolism and their involvement in neurodegenerative diseases.

Over the last two decades, in collaboration with Prof Brew, he demonstrated the importance of this pathway in Multiple Sclerosis, Alzheimer's disease, and amyotrophic lateral sclerosis. These results have opened promising research avenues, which are being translated into important new prognostic and therapeutic strategies.

Through their important international and national collaborative network, Prof Guillemin and his research team have extended their research to other diseases such as Parkinson’s disease, suicide, depression, autism, schizophrenia breast cancers and brain tumours.

Prof Guillemin work encompasses the:

  • Involvement of quinolinic acid and other tryptophan catabolites in the pathogenesis of neurodegenerative diseases including Motor Neurone Disease (MND), Alzheimer’s disease. Parkinson’s disease, Multiple Sclerosis.
  • Roles of the kynurenine pathway in the persistence and metastasis of breast cancer, brain tumour.
  • Identification of Biomarkers for the prognostic of amyotrophic lateral sclerosis, Alzheimer’s disease. Parkinson’s disease and Multiple Sclerosis.
  • Identification of environmental factors associated with neurodegenerative diseases.
  • Neuroprotective effects of Natural compounds for neurodegenerative diseases.
