Polyargininepeptide Arginine-rich cell-penetrating peptides (CPPs) represent a groundbreaking class of molecules engineered to traverse the formidable barrier of the cell membrane. These short, positively charged peptides owe their remarkable ability to penetrate eukaryotic cells to their high arginine content. Arginine residues, with their positively charged guanidino groups, are instrumental in mediating interactions with the negatively charged cellular membrane. This inherent property makes arginine-rich peptides exceptionally promising for a wide array of biomedical applications, particularly in the realm of intracellular drug delivery.

The fundamental mechanism by which arginine-rich cell-penetrating peptides achieve cellular entry is a subject of ongoing research, but key principles have emerged. Unlike conventional small molecule drugs that can diffuse directly through the lipid bilayer, arginine-rich CPPs utilize more complex pathways作者：BR Liu·2022·被引用次数：34—The membrane-activepeptidesare a term for thepeptidesthat are able to interact with lipid-bilayer membranes to cause leakage as well as damage oncell.... Studies suggest that they do not necessarily pass directly through the lipid membrane but rather interact with it, potentially forming transient pores or utilizing endocytic pathways. For instance, research by Allolio and colleagues (2018) indicates that arginine-rich cell-penetrating peptides can be passively incorporated into vesicles, facilitating their entry into cells. Furthermore, the work of Choe et al.作者：N Schmidt·2010·被引用次数：648—Arginine-rich cell-penetrating peptidesare short cationic peptides capable of traversing the plasma membranes of eukaryotic cells. (2024) highlights the role of membrane deformation and water pores in the translocation of these peptides.

The arginine content is not merely about charge; it influences the peptide's interaction with the cellular environment. Futaki et al. (2017) noted that the guanidino groups of arginine-rich CPPs are capable of forming significant hydrogen bonds, contributing to their strong affinity for cell surfaces.Arginine-rich cell-penetrating peptides induce membrane ...

This implies a dynamic interplay between the peptide and the cell's outer boundary.

Indeed, the efficacy of these peptides is often linked to specific structural characteristics. Lättig-Tünnemann et al. (2011) demonstrated that the transduction efficiency of arginine-rich peptides increases with higher peptide structural rigidity, underscoring the importance of peptide conformation in facilitating cell entry.
