21. Cell-penetrating peptides : Uptake, stability and biological activity
Sammanfattning : Cell-penetrating peptides (CPPs) have emerged as a group of remarkable delivery vectors for various hydrophilic macromolecules, otherwise excluded from cells due to the protective plasma membrane. Unbiased conclusions regarding e.g. LÄS MER
22. Cell-penetrating peptides in protein mimicry and oligonucleotide delivery : Applications and mechanisms
Sammanfattning : The plasma membrane functions as a barrier, restricting entry of hydrophilic pharmaceutical agents. Cell-penetrating peptides (CPPs) are capable of transporting bioactive cargos into the cell and have consequently been extensively investigated for their mechanism of entry and capability to deliver various cargos spanning from peptides to plasmids. LÄS MER
23. Cell-penetrating peptides as delivery vectors for oligonucleotides and proteins : Studies on applications and toxicity
Sammanfattning : Cell-penetrating peptides (CPPs) have for a little bit more than a decade been employed as delivery vectors for a wide range of cargoes, ranging from gold particles to entire plasmids. Although CPP are well studied and utilized in numerous publications, our knowledge about CPP mediated transport is still poor. LÄS MER
24. Cell-penetrating peptides and bioactive cargoes : Strategies and mechanisms
Sammanfattning : The cell membrane is an impermeable barrier for most macromolecules. Recently discovered cell-penetrating peptides (CPPs) have gained lot of attention because they can cross the membrane, and even more, carry cargoes with them. How CPPs enter cells is still not clear, while the delivery of different cargoes has been convincingly shown. LÄS MER
25. Acylated cell-penetrating peptides for nucleic acid delivery
Sammanfattning : In recent decades many new methods have been developed to cure or treat genetical disorders such as cancer, viral infections or inheritable diseases. The problem is that the nucleic acids and their synthetic analogs, oligonucleotides, are not able to cross the cell membrane due to their physicochemical properties like high negative charge and size.
