Prion Diseases

Overview
Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of rare, degenerative, and usually fatal diseases that affect the nervous system of humans and animals. They are caused by the misfolding of a normal cellular protein, the prion protein (PrP), into an abnormal form (PrP^Sc).
Key Characteristics
- Misfolded Proteins: Prion diseases are unique because they are caused by a misfolded protein rather than by a virus, bacterium, or other infectious agent.
- Neurodegenerative: They lead to progressive neurodegeneration, resulting in symptoms such as dementia.
- Medical Practice: Relies heavily on psychological-safety to mitigate errors and improve patient outcomes.
AI in Drug Discovery
The landscape of treating complex diseases like prion disorders is being transformed by artificial intelligence.
- Isomorphic Labs: A Google DeepMind spin-off focusing on AI-driven drug design.
- AlphaFold: Advancements in AI are enabling the prediction of protein structures, crucial for understanding protein-misfolding and designing interventions.
- Key Figures: Insights from Rebecca Paul (Head of Medicinal Drug Design) and Max Jaderberg (Chief AI Officer) highlight the shift towards AI-centric medicinal design.
