Discovery of antibody panel improves therapeutic delivery across the blood-brain barrier, suggesting new treatment options for neurological diseases.

The research aims to develop a panel of transferrin receptor antibodies to enhance drug delivery across the blood-brain barrier.
Utilized a yeast-based antibody discovery platform to identify antibodies targeting TfR.
Examined binding affinities and cross-reactivity of the antibodies.
Evaluated internalization in TfR-expressing cells and brain endothelial cells.
Created a panel of multispecific antibodies for in vivo permeability testing.
Identified diverse antibodies with varying affinities for TfR that do not interfere with transferrin.
Multispecific antibodies showed improved blood-brain barrier uptake compared to traditional antibodies.
The developed panel serves as a new tool for advancing neurological disease treatments.

Boland et al. (2026) studied this question.
