    IMD Research Round-Up: Lysosomal Storage Disorders
    2025/09/16
    Silvia and Rodrigo are joined by Dr Ray Wang, Director of the multidisciplinary Foundation of Caring Lysosomal Storage Disorder Program at the Children's Hospital of Orange County. Silvia asks Dr Wang and Rodrigo (who also happens to be a researcher in this field) about cutting-edge advances in LSD research: from base editing in Pompe disease and patient-specific in vivo gene editing, to new biomarkers and scoring systems in Gaucher disease, insights into lipid dysregulation across lysosomal storage disorders, and the first clinical trial of anakinra in Sanfilippo syndrome. Papers discussed include: Christensen CL, et al Base editing rescues acid α-glucosidase function in infantile-onset Pompe disease patient-derived cells.

  • Adenosine Kinase

    Adenosine Kinase
    2025/09/09
    What if one enzyme could link metabolism, epigenetics, and therapy across conditions as diverse as epilepsy, cancer, and inflammation? In this episode, we dive into the fascinating world of adenosine kinase (ADK), an ancient enzyme that controls adenosine levels, energy balance, and even DNA methylation. Dr Detlev Boison join us to discuss their recent review in the Journal of Inherited Metabolic Disease, which reframes ADK not just as a metabolic regulator, but as a potential epigenetic drug target. From seizure suppression to cancer immunology, ADK sits at a crossroads, and could be a future key to metabolic and epigenetic medicine.

  • The treatment landscape in CDG

    The treatment landscape in CDG
    2025/08/19
    In this episode, we speak with Irena Muffels and Eva Morava about their recent review, The Therapeutic Future for Congenital Disorders of Glycosylation. We explore the three pillars they propose for advancing CDG treatment: improving disease models, enhancing clinical trial readiness, and finding scalable strategies that move us beyond one-gene-at-a-time approaches. From patient-derived brain organoids to AI-powered outcome assessments and the promise of basket trials, this conversation is a sweeping tour through the innovations shaping the future of CDG care.
