What are the four human prion diseases?
Background. Human prion diseases, also named transmissible spongiform encephalopathies (TSEs), are fatal neurodegenerative disorders, which include Kuru, Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker syndrome (GSS), and fatal familial insomnia (FFI).
How many different prions are there?
There are around 28 different potions in Minecraft. Some potions have an instant effect, while others last for a specific time duration. Potions have been in the game since Minecraft’s release. Players can brew potions in a brewing stand using blaze powder, potion ingredients, and water bottles.

Is Parkinson’s disease a prion disease?
Formation and aggregation of misfolded proteins in the central nervous system (CNS) is a key hallmark of several age-related neurodegenerative diseases, including Parkinson’s disease (PD), Alzheimer’s disease (AD), and amyotrophic lateral sclerosis (ALS).
How do you classify prions?
Classification. Prions have not been classified in the same way as viruses, thus there are no families, genera, or species. They first are identified by their host species, clinical disease, and their associated lesions (Table 31.1), and then characterized further by their molecular and biological properties.

Symptoms of prion diseases include:
- Rapidly developing dementia.
- Difficulty walking and changes in gait.
- Muscle stiffness.
- Difficulty speaking.
Is Alzheimer’s disease prion?
Credit: Prusiner lab / UCSF Institute for Neurodegenerative Diseases. Two proteins central to the pathology of Alzheimer’s disease act as prions — misshapen proteins that spread through tissue like an infection by forcing normal proteins to adopt the same misfolded shape — according to new UC San Francisco research.
How do humans get prion disease?
Prion diseases can be transmitted through contaminated medical equipment and nervous tissue. Cases where this has happened include transmission through contaminated cornea transplants or dura mater grafts.
