Discovery of [18F]-MK-6240: A Positron Emission Tomography (PET) Imaging Agent for Quantification of Neurofibrillary Tangles (NFTs)

Neurofibrillary tangles (NFTs) made up of aggregated tau protein have been identified as the pathologic hallmark of several neurodegenerative diseases including Alzheimer's disease. In vivo detection of NFTs using PET imaging represents a unique opportunity to develop a pharmacodynamic tool to accelerate discovery of new disease modifying therapeutics targeting tau pathology. Herein we present the [...]

Alectos Announces Preclinical Results in TAPP Mouse Model of Alzheimer’s Disease

Oct 26, 2014 – Alectos today announced publication of preclinical studies showing that pharmacological inhibition of O-GlcNAcase (OGA) prevents cognitive decline and amyloid plaque formation in the TAPP mouse model of Alzheimer’s disease. For details, see: Yuzwa, S.A. et al. Mol Neurodegener 9:42 (2014).

Pharmacological inhibition of O-GlcNAcase (OGA) prevents cognitive decline and amyloid plaque formation in bigenic tau/APP mutant mice

BACKGROUND: Amyloid plaques and neurofibrillary tangles (NFTs) are the defining pathological hallmarks of Alzheimer's disease (AD). Increasing the quantity of the O-linked N-acetylglucosamine (O-GlcNAc) post-translational modification of nuclear and cytoplasmic proteins slows neurodegeneration and blocks the formation of NFTs in a tauopathy mouse model. It remains unknown, however, if O-GlcNAc can influence the formation of [...]
