# AI-designed proteins neutralise deadly snake-venom toxins and protect mice

Baker lab and DTU researchers (Nature, Jan 2025) used RFdiffusion to design small proteins that bind and neutralise cobra three-finger toxins. Depending on dose, toxin and design, 80–100% of mice survived otherwise lethal doses.

## Key facts
- Designed binders against short- and long-chain three-finger toxins
- 80–100% survival in mice given lethal doses
- Small, stable proteins could be cheaper to make than antibody-based antivenoms

## What happened

The team generated binders computationally, tested a small number in the lab, and confirmed protection in animal models.

## Why it matters

Snakebite kills tens of thousands of people a year, mainly in poor regions. Cheap, designed antitoxins show AI protein design aimed at neglected diseases.
