A broad range of cell penetrating peptides (CPPs) are used to deliver drug molecules into cells. These peptides are able to penetrate the lipid layer of the cell membrane in a controlled manner and translocate directly into the cytoplasm. They can be categorized into two broad categories: endocytosis and direct penetration, although there are some differences between them.
Several factors determine the cellular uptake of CPPs. These include the physicochemical properties of the peptide and its cargo, its concentration, the type of cell line, and the temperature at which the uptake studies were performed and the incubation time.
The net charge of the peptide is another important factor that influences the uptake pathway. It is believed that positively charged peptides are more likely to be absorbed than negatively charged ones.
