In primary culture of mouse hippocampal neurons, peptide EDR (200 ng/ml) under conditions of amyloid synaptotoxicity (a model of Alzheimer's disease) increased the number of mushroom spines by 71% and returned this parameter to the normal level. Under the same conditions, tripeptide KED (200 ng/ml) increased the number of mushroom spines in hippocampal neurons by 20%. Tripeptide EDR can be recommended for further experimental study as a candidate neuroprotective agent for prevention and treatment of Alzheimer's disease.
在小鼠海马神经元的原代培养中，在淀粉样突触毒性（阿尔茨海默病模型）条件下，肽EDR（200 ng/ml）使蘑菇状棘突的数量增加了71%，并使该参数恢复到正常水平。在相同条件下，三肽KED（200 ng/ml）使海马神经元中蘑菇状棘突的数量增加了20%。三肽EDR作为预防和治疗阿尔茨海默病的候选神经保护剂，可推荐用于进一步的实验研究。
