Peptide PHDP5 May Reverse Cognitive Impairment in Alzheimers Disease (2024 Research)

TLDR: Researchers demonstrated that intranasal administration of the peptide FITC-PHDP5-CPP reverses early cognitive impairment in Alzheimer’s disease (AD) model mice, showing potential as a treatment for AD-associated cognitive decline. Highlights: PHDP5, derived from the pleckstrin homology domain of dynamin 1, inhibits the interaction between dynamin and microtubules, rescuing synaptic dysfunction caused by tau accumulation. The …
