The fundamental characteristic of CPPs is their capacity to bypass the typically restrictive nature of the cell membrane. While the exact mechanisms are still under investigation and likely vary between different CPPs, several models have been proposed. These include direct penetration through the lipid bilayer, formation of transient pores, and endocytosis-mediated pathways.Cell penetrating peptides: overview and applications to the ... Many CPPs share common features, such as a positive net charge and/or an amphipathic nature, which are believed to play a role in their interaction with the negatively charged cell surface and subsequent translocation.

Numerous examples of CPPs have been identified, originating from both natural sources and through synthetic design.作者：S Aroui·2020·被引用次数：18—Example of origin of four CPPs:Maurocalcine, penetratin, tat, and polyarginine.

Arg-rich peptides, such as the Tat peptide and various lengths of oligoarginine chains (e.g., R8 to R12, where R signifies arginine residues), are highly efficient CPPs. The increasing length of oligoarginine chains generally enhances cellular internalization, although this can sometimes come at the cost of elevated cytotoxicity.作者：E BÖHMOVÁ·2018·被引用次数：133—Examples of such compounds arenatural saponins, which are used in molecular biology or microbiology as membrane-permeating substances (Wojciechowski et al. These arginine-rich cell-penetrating peptides (CPPs) are particularly effective due to the strong positive charge conferred by the multiple arginine residues, which facilitates electrostatic interactions with the cell membrane.Examples of cell-penetrating peptides, their origins, ...
