Mechanistic description

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.

Mechanism / pathway

  1. G3BP1
  2. Stress granule assembly / liquid-liquid phase separation
  3. neurodegeneration

Evidence for (3)

  • TDP-43, tau, and α-synuclein co-localize in stress granules where cross-seeding occurs

    PMID:31959759

  • Liquid-liquid phase separation drives pathological protein aggregation

    PMID:32296183

  • Small molecules can modulate biomolecular condensate properties

    PMID:33658718

Evidence against (3)

  • Stress granules may be protective by sequestering aggregation-prone proteins

    PMID:31959759

  • Phase separation is essential for normal cellular function, making modulation risky

    PMID:33658718

  • Many phase separation modulators are toxic at effective concentrations
