The Disease You Will Never Survive

TL;DR

Prions are misfolded proteins that cause incurable diseases by disrupting nerve signals in the brain, leading to organ failure and death.

Transcript

There’s a type of disease that infects a person’s  brain, is incredibly hard to detect, can kill   extremely quickly, and has no known cure. Hi, I’m Lizah, and this is MinuteYIKES.  These deadly, incurable diseases all start  with proteins. Proteins are really long   chains of smaller molecules called amino acids.  Through intricate molecular origa... Read More

Key Insights

• 🤙 Proteins are essential for living organisms, but misfolded proteins called prions can have deadly consequences.
• 🥺 Prions disrupt nerve signals and form clumps in the brain, leading to organ failure and death.
• 🍖 Prion diseases can be caused by chance misfolding or genetic encoding, as well as through consumption of infected meat.
• 🕵️ Detecting and treating prion diseases is challenging due to the difficulty in detecting misfolded proteins.
• 💄 Prions, despite their dangerous nature, have also been found to have positive effects, such as making yeast cells more resilient.
• ⚾ DeepMind's AlphaFold system, based on AI, is helping researchers predict protein structures and accelerate scientific progress in various fields.
• 🥶 DeepMind and EMBL's European Bioinformatics Institute have released a free database, AlphaFold, with predicted protein structures, benefiting millions of researchers worldwide.

Questions & Answers

Q: What are prions, and how do they cause diseases?

Prions are misfolded proteins that disrupt nerve signals in the brain. When they come across normally functioning proteins, they induce the same misfolding, leading to a chain reaction and the formation of clumps within nerve cells.

Q: How do prion diseases differ from other contagious diseases?

Prion diseases are not contagious in the traditional sense and cannot be transmitted through casual contact. However, consuming infected meat, particularly from cows with mad cow disease, can lead to prion infection.

Q: Can prion diseases be detected and treated?

Prions are challenging to detect due to their similarity to normal proteins. Currently, there is no known cure for prion diseases, and researchers are working on technologies to either destroy or refold misfolded proteins.

Q: How common are prion diseases?

Prion diseases, such as Creutzfeldt-Jacobs disease, are extremely rare and are as uncommon as being struck by lightning.

Summary & Key Takeaways

• Proteins are important for various functions in living organisms, but misfolded proteins called prions can cause deadly diseases in the brain.

• Prion diseases, such as Creutzfeldt-Jacobs disease, lead to memory loss, organ failure, and death within a short period.

• Prions can be encoded in a person's DNA or transmitted through infected meat, such as mad cow disease.
