细胞穿膜肽是一类具有穿透细胞膜能力的短肽载体，可以转运小分子化合物、多肽、蛋白质、核酸和纳米颗粒等不具透膜能力的外源分子进入活细胞。

Cell-penetrating peptides ( CPPs ) are short peptide sequences with the ability to cross plasma membranes , therefore can be used as vectors for transport of various exogenous molecules without permeability into living cells , including small chemical molecules , peptides , proteins , nucleic acids and nanoparticles .

穿透机制包括被动转运、载体介导的转运、受体介导的转运、吸收介导的转运和外排泵活性的抑制。

The mechanisms across the BBB involve the passive diffusion , the carrier mediated transport , the receptor mediated endocytosis , the absorptive mediated endocytosis ( transcytosis ) and the inhibition of drug efflux from the CNS .
