1. What is the scientific name?Prion protein (PrP)
2. What is the significance?Causative agent of fatal neurodegenerative diseases (TSEs) in mammals, lacking genetic material
3. What are prions and why are they called tiny villains?Prions are tiny misfolded proteins that can trick normal proteins into folding the wrong way. This trick makes them harmful to the brain, like a sneaky villain.
4. How do prions make a normal protein become dangerous?A prion acts like a template, showing a normal protein how to fold incorrectly. The new misfolded protein then keeps copying the wrong shape, creating more prions.

Prion Protein (PrP): A cellular protein that can exist in a normal (PrPC) and a misfolded, infectious form (PrPSc).
Conformational Change: A change in the three-dimensional structure of a protein molecule.
Transmissible Spongiform Encephalopathies (TSEs): A group of fatal neurodegenerative diseases caused by prions, characterized by brain pathology including spongiosis.
