Introduction The biological membranes as natural permeable barriers are required for
survival and function of living cells. However, these natural barriers could be a major …

In recent years, vast amounts of data on the mechanisms of neural de-and regeneration
have accumulated. However, only in disproportionally few cases has this led to efficient …

Short oligomers of arginine, either alone or when conjugated to therapeutic agents or large
biopolymers, have been shown to cross readily a variety of biological barriers (eg, lipid …

A diversity of cell-penetrating peptides (CPPs), is known, but so far the only common
denominator for these peptides is the ability to gain cell entry in an energy-independent …

Cell‐penetrating peptides (CPPs) have become widely used vectors for the cellular import of
molecules in basic and applied biomedical research. Despite the broad acceptance of these …

Cell membranes act as protective walls to exclude most molecules that are not actively
imported by living cells. This is an efficient way for a cell to prevent uncontrolled influx or …

Recently, we described a new strategy for the delivery of proteins and peptides into
mammalian cells, based on an amphipathic peptide of 21 residues, Pep-1, which was …

This paper critically reviews reports on the interactions of phospholipids and poly (ethylene
glycol)(PEG)—also called poly (ethylene oxide)(PEO)—with biological systems (model …

Cell-penetrating peptides (CPPs) have been extensively studied during the past decade,
because of their ability to promote the cellular uptake of various cargo molecules, eg …

Cell-penetrating peptides (CPPs) have recently attracted much interest due to their apparent
ability to penetrate cell membranes in an energy-independent manner. Here molecular …
