Hypothesis
Liquid-Liquid Phase Separation Modifier Therapy
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.

🧪 Overview
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.

Supports
TDP-43, tau, and α-synuclein co-localize in stress granules where cross-seeding occurs
Contradicts
Stress granules may be protective by sequestering aggregation-prone proteins
Contradicts
Phase separation is essential for normal cellular function, making modulation risky
