Cell-penetrating peptides and antimicrobial peptides: how different are they?
Some cationic peptides, referred to as CPPs (cell-penetrating peptides), have the ability to translocate across biological membranes in a non-disruptive way and to overcome the impermeable nature of the cell membrane. They have been successfully used for drug delivery into mammalian cells; however, there is no consensus about the mechanism of cellular uptake. Both endocytic and non-endocytic pa...
متن کاملCell-Penetrating Peptides 811 Protein transduction: identification, characterization and optimization
Protein transduction domains (PTDs), both naturally occurring and synthetic, have been increasingly employed to deliver biologically active agents to a variety of cell types in vitro and in vivo. In addition to the previously characterized arginine-rich PTDs, including Tat (transactivator of transcription), Antp (Antennapedia) and PTD-5, we have demonstrated that lysine and ornithine, as well a...
متن کاملCell-penetrating peptides – mechanism of transduction and synthesis – short review
Potential antimicrobial agents may be effective if they are delivered efficiently to their site of action. In many cases, lack of permeability through the cell membrane is the main problem. One of the possible solutions could be a novel intracellular delivery system involving cell-penetrating peptides (CPPs), which may improve the efficiency of many new biopharmaceuticals. Among other things, C...
متن کاملSimple model of the transduction of cell-penetrating peptides.
Cell-penetrating peptides (CPPs) such as HIV's trans-activating transcriptional activator (TAT) and polyarginine rapidly pass through the plasma membranes of mammalian cells by an unknown mechanism called transduction. They may be medically useful when fused to well-chosen chains of fewer than about 35 amino acids. The author offers a simple model of transduction in which phosphatidylserines an...
متن کاملPeptides with Dual Antimicrobial and Anticancer Activities
In recent years, the number of people suffering from cancer and multi-resistant infections has increased, such that both diseases are already seen as current and future major causes of death. Moreover, chronic infections are one of the main causes of cancer, due to the instability in the immune system that allows cancer cells to proliferate. Likewise, the physical debility associated with cance...
