Activity

Blood-Brain Barrier
These peptide-based modulators (Trojans) were non-amyloidogenic, stable in serum and showed minimal

Target

Human brain endothelial cells (EA.hy926)

Assay & Model

Field-emission transmission electron microscope
A3 peptide treated with this peptide, showed higher folds of decrease in fluorescence intensities a
Origin/Source
Tauopathies
These peptides were capable of reducing the tau elicit toxicity by accelerating or impeding the self
