Kynurenine pathway (KP) is the major pathway of the essential amino acid tryptophan metabolism. We have several projects to understand the role of this pathway in stem cell biology and neurogenesis, and how this relates to diseases like Multiple Sclerosis (MS) where the pathway is dysregulated and produces toxic metabolites capable of killing brain cells. 




Our specific projects include:

  • Understanding KP signalling in adult stem cells and enhancing the brain’s regenerative capacity in neurodegenerative disorders like Multiple Sclerosis (MS).
  • Understanding how remyelination is repaired in MS as a basis for the development of future therapeutics targeting the KP.
  • Role of KP in circulating blood monocytes in progression of MS pathology.
  • Role of KP in Motor Neurone disease (MND) and how KP therapeutic inhibitors can help address the loss of brain cells in this disease
