Aguzzi推理说，PrP就是轴突里的信号分子，会使施沃恩细胞健康快乐。
Aguzzi theorizes that PrP is a signaling molecule in axons that's needed to "keep Schwann cells happy."
虽然当PrP缺失时，施沃恩细胞会受到疾病侵袭，蛋白质还是应该存在于轴突以防止疾病发生。这项研究成果发表在本周的《自然——神经系统科学》。
Even though the Schwann cells are the ones affected when PrP is missing, the protein must be present in axons to prevent disease, the researchers report online this week in Nature Neuroscience.
