Differential intercellular transmission efficiency of misfolded proteins (tau, α-synuclein, TDP-43) is determined by their distinct conformational epitopes that preferentially engage specific heparan sulfate proteoglycan (HSPG) subtypes on target cells. While tau and α-synuclein form incipient conformers with high-affinity HSPG binding motifs accessible for rapid endocytic uptake, TDP-43 adopts conformations with reduced HSPG affinity, resulting in slower uptake kinetics. Syndecan-3 and glypican
Different misfolded proteins may preferentially associate with distinct lipid raft compositions during membrane fusion events. Targeted lipid raft disruption using specific cholesterol-depleting agents could selectively impair transmission of particular protein species while preserving normal membrane functions.
