Small molecules quell toxic alpha-synuclein in preclinical studies

Wren Therapeutics has developed oral small molecules that suppress the production of toxic alpha-synuclein protein forms in cellular and mouse models used to study Parkinson’s disease. The potential first-in-class molecules were designed with Wren’s technology platform to hinder processes involved in the generation of alpha-synuclein oligomers, the…

High Copper Exposure May Promote Disease-driving Protein Clumping

Exposure to high concentrations of copper accelerates the formation of toxic clumps of the alpha-synuclein protein — a hallmark of Parkinson’s disease, a study shows. The study, “Single-Particle Resolution of Copper-Associated Annular α‑Synuclein Oligomers Reveals Potential Therapeutic Targets of Neurodegeneration,” was published in the journal…

ABBV-0805 Reduces Alpha-synuclein Clumping in Mice

ABBV-0805, AbbVie’s experimental antibody-based therapy for Parkinson’s disease, selectively binds to toxic clumps of the alpha-synuclein protein — a hallmark of the disease — preventing their spread and prolonging survival in mouse models of Parkinson’s, a study shows. Also, the investigational antibody was found to bind to harmful…

LL-37 Suppresses Alpha-synuclein Clumping in Parkinson’s

LL-37, a natural antimicrobial molecule present in the brain and gut, selectively binds to harmful clumps of the alpha-synuclein protein — a hallmark of Parkinson’s disease — and prevents their further aggregation and toxic effects in lab-grown nerve cells, a study shows. The discovery of such a strong suppressor…
