Cellular delivery of noncovalently-associated macromolecules by cell-penetrating peptides.
Cellular and nuclear delivery of biomolecules is limited by low membrane permeability. Cell-penetrating peptides (CPPs) can be covalently linked to cargos to improve cellular internalization. Our work indicates that arginine-rich CPPs are also able to interact with a variety of cargos, including DNA, RNA, proteins and nanomaterials, in a noncovalent manner and subsequently effect their delivery...
متن کاملCell penetrating and transytosing peptides: powerful strategies for oral insulin delivery
Insulin is essential for type 1 and advanced type 2 diabetes to maintain blood glucose levels and increase the patient’s longevity. Frequent subcutaneous insulin injections are usually associated with pain, local tissue necrosis, infection and nerve damage. Recently, a number of new delivery methods such as oral insulin delivery have been developed to overcome these limitations and increase pa...
متن کاملRational modifications of cell-penetrating peptides for drug delivery Applications in tumor targeting and oligonucleotide delivery
High molecular weight biomolecules are becoming increasingly important in the development of new therapeutics. However, the hydrophilic nature and size of such molecules creates a major limitation for their application – poor penetration through biological membranes. Over a decade ago, a new class of peptides, cell-penetrating peptides (CPPs), with membrane translocating ability, was discovered...
متن کاملApplications of cell-penetrating peptides in regulation of gene expression.
CPPs (cell-penetrating peptides) can be defined as short peptides that are able to efficiently penetrate cellular lipid bilayers. Because of this remarkable feature, they are excellent candidates regarding alterations in gene expression. CPPs have been utilized in in vivo and in vitro experiments as delivery vectors for different bioactive cargoes. This review focuses on the experiments perform...
متن کاملCell-penetrating peptides, electroporation and drug delivery.
Certain short polycations, such as trans-activating transcriptional activator and oligoarginine, rapidly pass through the plasma membranes of mammalian cells by a mechanism called transduction, as well as by endocytosis and macropinocytosis. These cell-penetrating peptides can carry with them cargos of 30 amino acids, more than the nominal limit of 500 Da and enough to be therapeutic. An analys...
