Overview

Protein binders reduce TDP-43 amyloid aggregation in cells, suggesting potential for ALS and FTLD therapy.

Key Points

  • The designed protein binders effectively reduced TDP-43 amyloid aggregation in vitro and in cells.
  • NMR and mutagenesis studies were used to characterize the binding mechanism of the proteins.
  • The strategy yielded proteins capable of stabilizing TDP-43 with nanomolar binding affinity.
  • This work provides insights into therapeutic approaches for neurodegenerative diseases like ALS and FTLD.
