Many diseases are driven by proteins interacting with each other inside cells. But blocking these interactions with drugs is difficult because typical "small-molecule" drugs often prove to be too small to grip the broad, flat surfaces involved in protein-protein interactions.

EPFL researchers have developed a type of peptides that can enter cells and block protein interactions considered difficult to target with drugs.
