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.
