Peptide fragment corresponding to residues 1 - 40 of Nogo-66, the domain of the myelin protein Nogo that inhibits axonal outgrowth. Acts as a competitive antagonist at the Nogo-66 receptor (NgR); blocks Nogo-66- and CNS myelin-induced inhibition of axonal growth, but does not reduce myelin-associated glycoprotein (MAG) inhibition of neurite outgrowth in vitro. Promotes regeneration of hemisected spinal axons and locomotor recovery following spinal injury in vivo.

Plasminogen Activator Inhibitor 1 (PAI-1)

Chromogranin A (324-337), human 是嗜铬粒蛋白 A 的一个肽片段，可从人的回肠类癌肿瘤中分离出来。嗜铬粒蛋白 A 是一种可溶性糖蛋白，与激素和神经肽一起储存在大多数（神经）内分泌细胞和神经元的分泌颗粒中，它也是神经内分泌肿瘤的血浆标志物。
