Neuropeptide Y (human) TFA, a compound implicated in Alzheimer's disease (AD), exhibits protective effects against β-Amyloid toxicity in rat cortical neurons.

It is showed that Neuropeptide Y (human) is able to protect cortical neurons from Aβ25-35 toxicity. 2 μM NPY abolishes the toxic effects of Aβ25-35 at 24 and 48 h. The same effect on neuronal survival is observed in neurons exposed to 1 μM and 0.5 μM Neuropeptide Y (human) pretreatments. Pretreatment with Neuropeptide Y (29-64), amide, human (TFA) Increases NGF Synthesis, reduces NGF mRNA, and restores NGF release in cortical neurons exposed to Aβ35-25[1].
