Intracellular delivery: exploiting viral membranotropic peptides.

Area of Science:

• Biochemistry
• Molecular Biology
• Cell Biology

Background:

• Understanding disease pathogenesis reveals new molecular targets for diagnosis and therapy.
• Macromolecular drugs require specific intracellular delivery, but biological membranes pose a significant barrier.
• Effective strategies for membrane translocation are crucial for therapeutic molecule delivery.

Purpose of the Study:

• To review viral-derived peptides, particularly those from viral entry proteins, as potential delivery vehicles.
• To highlight the role of membrane perturbation properties in facilitating cellular uptake.
• To explore novel molecular targets for improved disease diagnosis and therapy.

Main Methods:

• Review of scientific literature on viral entry proteins and cell-penetrating peptides (CPPs).
• Analysis of the mechanisms by which viral peptides induce membrane perturbation.
• Evaluation of CPPs as tools for translocating macromolecules across cell membranes.

Main Results:

• Viral entry proteins possess intrinsic properties for membrane perturbation.
• These viral-derived peptides can efficiently translocate macromolecules into cells.
• New translocating peptides are continuously being identified and described.

Conclusions:

• Viral-derived peptides, especially from entry proteins, show promise as drug delivery vehicles.
• Targeting intracellular compartments via membrane perturbation is key for advanced therapeutics.
• Further research into viral peptides can lead to improved diagnostic and therapeutic strategies.
