Translational diseases models and neurodegeneration

Laboratory of Experimental Medicine
Junior research group

Our group, Translational Disease Models and Neurodegeneration, studies how tau and α-synuclein aggregates form, spread, and disrupt neural systems in Parkinson’s disease, Alzheimer’s disease, and frontotemporal dementias. We focus on the structural and mechanistic steps that turn normal proteins into disease-driving assemblies, and how specific mutations alter their behaviour, stability, and ability to propagate.

We develop targeted strategies that directly engage these processes, including peptide inhibitors that block the α-synuclein NAC region and compounds that interfere with the VQIVYK motif of tau. Alongside these protein-directed approaches, we investigate Bruton’s tyrosine kinase (BTK) as a modulator of neuroinflammation and test BTK inhibitors and BTK-oriented PROTACs to understand how kinase signalling shapes disease progression.

A significant aspect of our work involves linking therapeutic discovery to biomarker development. We refine and apply seed amplification assays (RT-QuIC and IP/RT-QuIC) to detect and functionally characterise pathological tau and α-synuclein seeds in patient samples, and we use these assays to evaluate the impact of candidate inhibitors under clinically relevant conditions.

Our research uses a broad experimental toolbox, including iPSC-derived neurons and glia, 3D neural cultures, organoids, and microfluidic co-culture systems. Across these platforms, our goal is clear: to translate mechanistic insights into therapies and biomarkers that meaningfully advance the early detection and treatment of neurodegenerative diseases.

  • Mechanisms of protein aggregation and spreading
    We study how tau and α-synuclein aggregates form, how mutations alter their structure, and how these assemblies propagate through neural systems.
  • Targeted modulation of disease-driving proteins
    We design and evaluate peptide inhibitors and small-molecule modulators targeting disease-defining motifs such as the VQIVYK region of tau and the NAC domain of α-synuclein, alongside BTK-centered strategies including PROTAC approaches.
  • Functional biomarkers for early detection
    We advance seed amplification assays (RT-QuIC and IP/RT-QuIC) to detect and characterize pathological tau and α-synuclein seeds in patient samples, aiming to improve diagnostic precision and therapeutic monitoring.
  • Human-relevant cellular and tissue models
    We employ iPSC-derived neurons, 3D neural cultures, organoids, and microfluidic BBB models to recreate disease mechanisms and evaluate therapeutic interventions in physiologically meaningful settings.
  • Translational pharmacology and drug repurposing
    We explore kinase-driven pathways, including BTK, and assess repurposed anticancer and targeted agents for their relevance to neurodegenerative disease mechanisms.
  • Peptide inhibitors targeting α-synuclein seed activity
    Developing and validating NAC-focused peptide inhibitors in cellular models, patient-derived seed assays, and mouse models of synucleinopathy.
  • Tau mutation–sensitive inhibitor profiling
    Investigating how specific tau mutations alter aggregation behavior and determining which VQIVYK-targeting agents are most effective against mutation-driven forms of tau pathology.
  • Seed-based biomarker platforms
    Applying automated immunoprecipitation and RT-QuIC workflows to analyze α-synuclein and tau seeds from clinical samples, linking seed biology to therapeutic testing.
  • Advanced iPSC and 3D disease models
    Building and applying iPSC-derived neuronal systems, organoids, and engineered 3D co-cultures to test aggregation, spreading, neuroinflammation, and responses to targeted therapeutics.
  • BTK-directed therapeutic development
    Designing and evaluating BTK inhibitors and BTK-oriented PROTAC degraders, and assessing their impact on neuroinflammatory signaling and aggregation-linked pathology.
