A likely culprit was a small peptide called crh that is released in a part of the brain associated with stress and anxiety 一个很有可能的“犯罪分子”是一个被称为“ crh ”的短肽，这种短肽会被释放到大脑中和压力与焦虑相关的区域。
2.
And the positive clones were used as the immunogens to immunize mice . both of the serum and phage peptides were add to measure their effects on the growth of huvec ( human umbilical vascular endothelial cell ) 检验这种短肽可否模拟vegf的抗原决定簇诱发机体产生能与vegf结合的抗体，研究小鼠抗血清对huvec (人脐静脉血管内皮细胞)生长的抑制作用以及噬菌体表达的7肽和12肽对huvec生长的抑制作用。
