Compounds that modulate the surface tension and composition of biomolecular condensates could prevent the aberrant mixing of tau, α-synuclein, and TDP-43 within stress granules and other membraneless organelles where cross-seeding occurs. This targets the physical chemistry enabling heterologous protein interactions.
