    • The present invention provides a method of determining or identifying or isolating a cell-penetrating peptide (CPP) or analog or derivative thereof having cell-type selectivity and/or at least capable of passing through a Blood Brain Barrier of an animal subject. This invention also provides CPPs and analogs and derivatives thereof, such as those set forth in SEQ ID NOs: 1-27 of the Sequence Listing, and compositions comprising one or more of the CPPs, including conjugates in which a CPP or analog or derivative thereof is linked to a cargo molecule. The invention also provides methods for transporting cargo molecules across cell membranes to specific locations within cells, and for treating, preventing and/or diagnosing diseases that are treatable by a cargo molecule to which a CPP or analog or derivative of the invention is attached. The invention also provides tailored peptide libraries for use in identifying or isolating CPPs.
    • 本发明提供了确定或鉴定或分离具有细胞类型选择性和/或至少能够通过动物受试者的血液脑屏障的细胞穿透肽(CPP)或其类似物或衍生物的方法。 本发明还提供CPP及其类似物及其衍生物,例如序列表SEQ ID NO:1-27所列的那些,以及包含一种或多种CPP的组合物,包括其中CPP或其类似物或衍生物的缀合物 与货物分子有关。 本发明还提供了将货物分子跨细胞膜运送到细胞内的特定位置,以及用于治疗,预防和/或诊断本发明的CPP或类似物或衍生物所连接的货物分子可治疗的疾病的方法。 本发明还提供用于鉴定或分离CPP的定制肽文库。
