What molecular mechanisms enable Gal3 to enhance tau fibrillation upon binding to pTau?
PARTIALLY ADDRESSED
The abstract shows that Gal3 binding to pTau greatly enhances tau fibrillation, but the specific molecular interactions and structural changes driving this enhancement are not explained. Understanding this mechanism is critical for developing targeted therapeutics that could disrupt this pathogenic interaction.
