At the core of their functionality lies the amino acid arginine (Arg or R). The abundance of this positively charged amino acid within a peptide sequence grants it unique properties作者:S Futaki·2001·被引用次数:2264—In this report, we have shown that not only Tat-(48–60) but also variousarginine-rich peptideswere able to translocate through the mouse macrophage membranes.. Cationic arginine-rich peptides (CARPs), a notable subset, are characterized by their strong positive charge, which facilitates their interaction with the negatively charged components of cell membranesArginine-rich peptides. An abundant source of membrane- .... This interaction is a key factor in their ability to penetrate cellular barriers. Research has indicated that arginine-rich CPPs exhibit higher transmembrane efficiency due to bidentate bonding between their guanidinium groups and these negatively charged cellular components.
The mechanisms by which arginine-rich peptides achieve cellular entry are diverse and have been a subject of extensive investigation. While early theories focused on direct passage through the lipid bilayer, current understanding encompasses both endocytic and non-endocytic pathways.作者:S Futaki·2001·被引用次数:2264—We found thatvarious arginine-rich peptideshave a translocation activity very similar to Tat-(48-60). Studies have shown that arginine-rich HIV Tat peptides, for instance, may translocate by destabilizing the plasma membrane and inducing transient pores, a mechanism distinct from direct membrane traversal. Conversely, other arginine-rich cell-penetrating peptides have been observed to enter cells via endocytic routes, such as macropinocytosis. For instance, the uptake of octa-arginine (R8) peptide by HeLa cells was significantly suppressed by macropinocytosis inhibitors, highlighting the role of this specific pathway.Extracellular Microvesicles Modified with Arginine-Rich ... The precise methods of translocation through biological membranes continue to be explored, contributing to a deeper comprehension of their internalization mechanisms.
The implication of these translocation abilities is profound, particularly for intracellular delivery of various mols (molecules).作者:G Tesei·2017·被引用次数:92—Arginine-rich cell-penetrating peptidesare promising candidates for intracellular drug delivery. These cationic peptides spontaneously ... Arginine-rich peptides and polyarginine peptides have demonstrated a significant capacity for penetrating cell membranes, making them promising candidates for delivering therapeutic agents into cells. This opens avenues for treating diseases where drug efficacy is limited by poor cellular uptake. Furthermore, arginine-rich peptides have shown potential as modulators of cellular processes.Arginine-rich peptides. An abundant source of membrane- ... For example, ionic arginine-rich peptides have inspired research into disrupting pathological crystallization, as seen in studies involving galectin-10.
Beyond direct delivery, the inherent properties of these peptides are being explored for other applications. Amphipathic arginine-rich peptide, A2-17, for instance, exhibits membrane perturbation and high cell penetration, suggesting its utility in modulating membrane properties or enhancing the cellular uptake of co-delivered cargo作者:N Schmidt·2010·被引用次数:648—Arginine-richcell-penetratingpeptidesare short cationicpeptidescapable of traversing the plasma membranes of eukaryotic cells.. The ability of arginine-rich peptides to interact with differently charged lipid bilayers is also a crucial aspect of their function, influencing their behavior at the cell surface.
The broader importance of arginine itself cannot be overlooked. As an essential amino acid, L-arginine is an amino acid that helps your body produce proteins, which are fundamental to every cell's function. This fundamental biological role underscores the significance of compounds derived from or rich in this amino acid.
In summary, arginine-rich peptides are a class of molecules with significant implications in cell biology and therapeutics.
