Potential Reversal of Alzheimer’s Disease pathology by Antibody TB006 Targeting Galectin‐3, the Root Cause of Oligomerization of Amyloid Proteins

Alzheimer’s disease (AD) is a chronic progressive neurodegenerative disorder caused by multiple pathogenic factors including Amyloid‐β (Aβ), phospho‐Tau (pTau), alpha‐synuclein, and ApoE4, etc. It is widely accepted that intermediate oligomeric forms, rather than monomers or mature fibrils, are more neurotoxic. Galectin‐3 (Gal‐3) was reported to be involved in Aβ oligomerization. Here, we show that Gal‐3 promotes oligomerization of Aβ and other pathogenic factors, and TB006, a monoclonal antibody targeting Gal‐3, acts as a possible treatment for AD by degrading neurotoxic oligomers.
