Gut–brain origin
The lane
- Status
- Open. The evidence points both ways; no therapy has been tested to the end.
- Verdict
- Mouse spread, registry data and body-first/brain-first subtypes are suggestive; faecal-transplant trials gave mixed results.
- Family
- Synuclein
- Landmarks
- 14 in this lane, 3 more tagged with it. Advanced 2 · Open 9 · Superseded 1 · Dead end 2
The verdict and status come from the project's branches.yaml and use research wording.
