mThy1 - AS mice administered only control IgG1 suffered dendritic atrophy (as suggested by reduced staining with MAP2) and synaptic loss (evaluated with postsynaptic density - 95 (PSD - 95) and synaptophysin) across several regions of the brain, but this neurodegenerative damage was substantially prevented in mice administered 1H7, 5C1, or 9E4.
Based upon activity in multiple CNS toxicity assays, we identified an exceptionally potent, orally active, neurotrophic molecule called J147 that facilitates memory in normal rodents, and prevents the loss of synaptic proteins and cognitive decline when administered to three - month - old APP / swePS1ΔE9 mice for seven months [7].
