Peptide-based and polypeptide-based gene carriers are emerging as the most potentially useful agents in the field of gene therapy. Here we summarize the methods used for the preparation of peptides and polypeptides, address the primary types of peptide-based gene delivery systems, demonstrate their applications in gene therapy, and attempt to propose possible future directions in the development of peptide-based and polypeptide-based gene carriers for specific applications.
