Arginine-rich cell-penetrating peptide-modified extracellular vesicles for active macropinocytosis induction and efficient intracellular delivery

Scientific Reports, 2017
Extracellular vesicles (EVs) including exosomes have been shown to play crucial roles in cell-to-cell communication because of their ability to carry biofunctional molecules (e.g., microRNAs and enzymes).

Programmable DNA‐Peptide Hybrid Nanostructures for Potent Neutralization of Multiple Influenza a Virus Subtypes

Advanced Functional Materials, EarlyView.
A multivalent antiviral platform based on honeycomb‐shaped DNA nanostructures (HC–Urumin) is developed to enhance the potency and breadth of the host defense peptide Urumin. Through spatially patterned trimeric presentation, HC–Urumin disrupts influenza A virus entry, improves cell viability, and reduces disease severity in vivo‐offering a modular and ...

Cell-Penetrating Peptides: Mechanisms and Applications

Current Pharmaceutical Design, 2005
A major obstacle in the development of new therapeutic agents is the low bioavailability of hydrophilic substances. Drugs that bind to intracellular targets must penetrate the lipid bilayer surrounding the cell in order to exert their effect. A relatively new research area that addresses this problem by introducing novel transport peptides that ...

CPPpred: prediction of cell penetrating peptides [PDF]

Bioinformatics, 2013
Abstract Summary: Cell penetrating peptides (CPPs) are attracting much attention as a means of overcoming the inherently poor cellular uptake of various bioactive molecules. Here, we introduce CPPpred, a web server for the prediction of CPPs using a N-to-1 neural network.
