NeuropeptideY(29-64),amide,human(TFA)和阿尔兹海默症相关，能够保护老鼠皮质神经元对抗淀粉样蛋白毒性。
Neuropeptide Y (29-64), amide, human (TFA) is involved in Alzheimer's disease (AD) and protects rat cortical neurons against β-Amyloid toxicity.
It is showed that Neuropeptide Y (29-64), amide, human (TFA) 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 (29-64), amide, human (TFA) 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].

Cell experiment: | Primary cortical neurons are preincubated either alone (positive control) or with three concentrations of Neuropeptide Y (29-64), amide, human (TFA) (NPY) (0.5, 1, and 2 μM) for 24 h and then exposed to Aβ25-35 (50 μM) or Aβ35-25 (50 μM) for 48 h[1]. |
