Research Interests

Maria João Silva has been studying Inborn Errors of Metabolism, specifically disorders of energy metabolism associated to Pyruvate Dehydrogenase Complex (PDHc) deficiency and Classical galactosemia. She focused on the development/optimization of methodology allowing PDHc deficiency diagnosis at the biochemical and molecular level. Presently, she is studying the effect of arginine as a chemical chaperone, assisting the correct folding of variant forms of PDHc E1a subunit as a new therapy for the treatment of mild PDHc phenotypes associated with misfolded variants.
