Kind: research · Impact: medium

## In brief

- A study reports that the blood-brain barrier imports diverse plasma proteins into specific brain cell types via receptor-mediated transport.
- The import process is dysregulated early in Alzheimer's disease models.
- Restoring one diminished liver-derived protein is described in the cell.com summary as a focus of the work.

## Why it matters

The findings suggest that impaired protein transport across the blood-brain barrier may be an early feature of Alzheimer's disease models, pointing to transport pathways as possible therapeutic targets.
