In terms of what cures are being lost:

- Epstein-Barr virus is perhaps the major trigger for multiple sclerosis
- herpes simplex virus causes cold sores, genital herpes, infections in babies, deadly meningitis
- shingles virus causes an intensely painful disease

Avez vous déjà vu ? Des zombosomes transportant de l’alpha synucleine

CC. @fredericblanc.bsky.social
🧠 Brain cells spawn zombielike vesicles.

These mobile structures move, carry mitochondria, and spread alpha synuclein between brain cells despite lacking a nucleus.

They may represent a new mechanism behind neurodegenerative disease spread.
