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.

Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.

Novel Therapeutic Hypotheses for Cross-Seeding in Neurodegeneration
Description: DNAJB6 specifically recognizes and suppresses amyloidogenic β-sheet conformations shared across tau, α-synuclein, and TDP-43 aggregates. Enhanced DNAJB6 expression or small molecule activators could provide broad-spectrum protection against cross-seeding by disrupting the common structural motifs that enable heterologous nucleation.
Target: DNAJB6 (DnaJ heat shock protein family member B6)
Supporting Evidence: DNAJB6 pote
