Cell-Penetrating Peptides: A Challenge for Drug Delivery

TLDR
An overview of the current approaches and the potential of CPP-based drug delivery systems are described and their powerful promise for clinical efficacy is indicated.
Abstract
Cell-penetrating peptide (CPP) is a term that describes relatively short amphipathic and cationic peptides (7–30 amino acid residues) with rapid translocation across the cell membrane. They can be used to deliver molecular bioactive cargoes due to their efficacy in cellular internalization and also to their low cytotoxicity. In this review we provide an overview of the current approaches and describe the potential of CPP-based drug delivery systems and indicate their powerful promise for clinical efficacy.

A truncated HIV-1 Tat protein basic domain rapidly translocates through the plasma membrane and accumulates in the cell nucleus

TL;DR: The main determinants required for Tat translocation within this sequence are delineated by synthesizing several peptides covering the Tat domain from residues 37 to 60 and the domain extending from amino acid 37 to 47, which corresponds to the α-helix structure, is not required for cellular uptake and for nuclear translocation.
