Dowaidar M. Uptake pathways of cell-penetrating peptides in the context of drug delivery, gene therapy, and vaccine development. Cell Signal 2024; 117:111116. [PMID: 38408550 DOI: 10.1016/j.cellsig.2024.111116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/19/2024] [Accepted: 02/21/2024] [Indexed: 02/28/2024]
Abstract
Cell-penetrating peptides have been extensively utilized for the purpose of facilitating the intracellular delivery of cargo that is impermeable to the cell membrane. The researchers have exhibited proficient delivery capabilities for oligonucleotides, thereby establishing cell-penetrating peptides as a potent instrument in the field of gene therapy. Furthermore, they have demonstrated a high level of efficiency in delivering several additional payloads. Cell penetrating peptides (CPPs) possess the capability to efficiently transport therapeutic molecules to specific cells, hence offering potential remedies for many illnesses. Hence, their utilization is imperative for the improvement of therapeutic vaccines. In contemporary studies, a plethora of cell-penetrating peptides have been unveiled, each characterized by its own distinct structural attributes and associated mechanisms. Although it is widely acknowledged that there are multiple pathways through which particles might be internalized, a comprehensive understanding of the specific mechanisms by which these particles enter cells has to be fully elucidated. The absorption of cell-penetrating peptides can occur through either direct translocation or endocytosis. However, it is worth noting that categories of cell-penetrating peptides are not commonly linked to specific entrance mechanisms. Furthermore, research has demonstrated that cell-penetrating peptides (CPPs) possess the capacity to enhance antigen uptake by cells and facilitate the traversal of various biological barriers. The primary objective of this work is to examine the mechanisms by which cell-penetrating peptides are internalized by cells and their significance in facilitating the administration of drugs, particularly in the context of gene therapy and vaccine development. The current study investigates the immunostimulatory properties of numerous vaccine components administered using different cell-penetrating peptides (CPPs). This study encompassed a comprehensive discussion on various topics, including the uptake pathways and mechanisms of cell-penetrating peptides (CPPs), the utilization of CPPs as innovative vectors for gene therapy, the role of CPPs in vaccine development, and the potential of CPPs for antigen delivery in the context of vaccine development.

Characterization and Evaluation of Cell-Penetrating Activity of Brevinin-2R: An Amphibian Skin Antimicrobial Peptide. Mol Biotechnol 2022; 64:546-559. [PMID: 35013881 DOI: 10.1007/s12033-021-00433-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 12/01/2021] [Indexed: 10/19/2022]
Abstract
Natural peptides have been the source of some important tools to address challenges in protein therapy of diseases. Bypassing cell plasma membrane has been a bottleneck in the intracellular delivery of biomolecules. Among others, cell-penetrating peptides (CPPs) provide an efficient strategy for intracellular delivery of various cargos. Brevinin-2R peptide is an antimicrobial peptide isolated from the skin secretions of marsh frog, Rana ridibunda with semi-selective anticancer properties. Here, we investigated cell-penetrating properties of Brevinin-2R peptide and its ability to deliver functional protein cargos. Bioinformatics studies showed that Brevinin-2R is a cationic peptide with a net charge of + 5 with an alpha-helix structure and a heptameric ring at the carboxylic terminal due to disulfide bond between C19 and C25 amino acids and a hinge region at A10. To evaluate the ability of this peptide as a CPP, β-galactosidase protein and GFP were transfected into HeLa cells. The entry pathway of the peptide/protein complex into the cell was investigated by inhibiting endocytic pathways at 4 °C. It was observed that Brevinin-2R can efficiently transfer β-galactosidase and GFP with 21% and 90% efficacy, respectively. Brevinin-2R opts for endocytosis pathways to enter cells. The cytotoxicity of this peptide against HeLa cells was studied using MTT assay. The results showed that at the concentration of 131.5 μg/ml of Brevinin-2R peptide, the proliferation of 50% of HeLa cells was inhibited. The results of this study suggest that Brevinin-2R peptide can act as a CPP of natural origin and low cytotoxicity.

Abstract
Selective permeability of biological membranes represents a significant barrier to the delivery of therapeutic substances into both microorganisms and mammalian cells, restricting the access of drugs into intracellular pathogens. Cell-penetrating peptides usually 5-30 amino acids with the characteristic ability to penetrate biological membranes have emerged as promising antimicrobial agents for treating infections as well as an effective delivery modality for biological conjugates such as nucleic acids, drugs, vaccines, nanoparticles, and therapeutic antibodies. However, several factors such as antimicrobial resistance and poor drug delivery of the existing medications justify the urgent need for developing a new class of antimicrobials. Herein, we review cell-penetrating peptides (CPPs) used to treat microbial infections. Although these peptides are biologically active for infections, effective transduction into membranes and cargo transport, serum stability, and half-life must be improved for optimum functions and development of next-generation antimicrobial agents.

Abstract
The cytotoxic mode of action of four antimicrobial peptides (AMPs) (gomesin, tachyplesin, protegrin, and polyphemusin) against a HeLa cell tumor model is discussed. A study of cell death by AMP stimulation revealed some similarities, including annexin-V externalization, reduction of mitochondrial potential, insensitivity against inhibitors of cell death, and membrane permeabilization. Evaluation of signaling proteins and gene expression that control cell death revealed wide variation in the responses to AMPs. However, the ability to cross cell membranes emerged as an important characteristic of AMP-dependent cell death, where endocytosis mediated by dynamin is a common mechanism. Furthermore, the affinity between AMPs and glycosaminoglycans (GAGs) and GAG participation in the cytotoxicity of AMPs were verified. The results show that, despite their primary and secondary structure homology, these peptides present different modes of action, but endocytosis and GAG participation are an important and common mechanism of cytotoxicity for β-hairpin peptides.

Abstract
Specificity is a crucial condition that hampers the application of non-viral vectors for cancer gene therapy. In a previous study, we developed an efficient gene vector, stearyl-CAMEL, using N-terminal stearylation of the antimicrobial peptide CAMEL. Substance P (SP), an 11-residue neuropeptide, rapidly enters cells after binding to the neurokinin-1 receptor (NK1R), which is expressed in many cancer cell lines. In this study, the NK1R-targeted gene vector stearyl-CMSP was constructed by conjugating SP to the C-terminus of stearyl-CAMEL. Our results indicated that stearyl-CMSP displayed significant transfection specificity for NK1R-expressing cells compared with that shown by stearyl-CAMEL. Accordingly, the stearyl-CMSP/p53 plasmid complexes had significantly higher antiproliferative activity against HEK293-NK1R cells than they did against HEK293 cells, while the stearyl-CAMEL/p53 plasmid complexes did not show this specificity in antiproliferative activity. Consequently, conjugation of the NK1R-targeted ligand SP is a simple and successful strategy to construct efficient cancer-targeted non-viral gene vectors.

Abstract
Although cell-penetrating peptides (CPPs) has been proven to be efficient transporter for drug delivery, ideal peptide vectors for tumor therapy are still being urgently sought. Peptide antagonists have attracted substantial attention as targeting molecules because of their high tumor accumulation and antitumor activity compared with agonists. SPA, a derivative of substance P, is a potent antagonist that exhibits antitumor activity. Based on the amino acid composition of SPA, we speculate that it can translocate across cell membranes as CPPs do. In this study, our results demonstrated that SPA could enter cells similarly to a CPP. As a vector, SPA could efficiently deliver camptothecin and plasmids into cells. In addition, our results showed that SPA exhibited low toxicity to normal cells and high enzymatic stability. Taken together, our results validated the ability of SPA for efficient drug delivery. More importantly, our study opens a new avenue for designing ideal CPPs based on peptide antagonists.

Abstract
Cell penetrating peptides (CPPs), also known as protein transduction domains (PTDs), first identified ~25 years ago, are small, 6-30 amino acid long, synthetic, or naturally occurring peptides, able to carry variety of cargoes across the cellular membranes in an intact, functional form. Since their initial description and characterization, the field of cell penetrating peptides as vectors has exploded. The cargoes they can deliver range from other small peptides, full-length proteins, nucleic acids including RNA and DNA, liposomes, nanoparticles, and viral particles as well as radioisotopes and other fluorescent probes for imaging purposes. In this review, we will focus briefly on their history, classification system, and mechanism of transduction followed by a summary of the existing literature on use of CPPs as gene delivery vectors either in the form of modified viruses, plasmid DNA, small interfering RNA, oligonucleotides, full-length genes, DNA origami or peptide nucleic acids.

Abstract
Nonviral vector-based gene therapy is a promising strategy for treating a myriad of diseases. Cell-penetrating peptides are gaining increasing attention as vectors for nucleic acid delivery. However, most studies have focused more on the transfection efficiency of these vectors than on their specificity and toxicity. To obtain ideal vectors with high efficiency and safety, we constructed the vector stearyl-TH by attaching a stearyl moiety to the N-terminus of the acid-activated cell penetrating peptide TH in this study. Under acidic conditions, stearyl-TH could bind to and condense plasmids into nanoparticle complexes, which displayed significantly enhanced cellular uptake and transfection efficiencies. In contrast, stearyl-TH lost the capacities of DNA binding and transfection at physiological pH. More importantly, stearyl-TH and the complexes formed by stearyl-TH and plasmids displayed no obvious toxicity at physiological pH. Consequently, the high transfection efficiency under acidic conditions and low toxicity make stearyl-TH a potential nucleic acid delivery vector for gene therapy.

Abstract
Transfection is a process by which oligonucleotides (DNA or RNA) are delivered into living cells. This allows the synthesis of target proteins as well as their inhibition (gene silencing). However, oligonucleotides cannot cross the plasma membrane by themselves; therefore, efficient carriers are needed for successful gene delivery. Recombinant viruses are among the earliest described vectors. Unfortunately, they have severe drawbacks such as toxicity and immunogenicity. In this regard, the development of non-viral transfection vectors has attracted increasing interests, and has become an important field of research. In the first part of this review we start with a tutorial introduction into the biological backgrounds of gene transfection followed by the classical non-viral vectors (cationic organic carriers and inorganic nanoparticles). In the second part we highlight selected recent reports, which demonstrate that hybrid vectors that combine key features of classical carriers are a remarkable strategy to address the current challenges in gene delivery.

Abstract
In 1988, two unrelated papers reported the discovery of peptide vectors with innate cell translocation properties, setting the ground for a new area of research that over the years has grown into considerable therapeutic potential. The vectors, named cell-penetrating peptides (CPPs), constitute a now large and diversified family, sharing the extraordinary ability to diffuse unaltered across cell membranes while ferrying diverse associated cargos. Such properties have made CPPs ideal tools for delivery of nucleic acids, proteins and other therapeutic/diagnostic molecules to cells and tissues via covalent conjugation or complexation. This year 2018 marks the 30th anniversary of a peptide research landmark opening new perspectives in drug delivery. Given its vastness, exhaustive coverage of the main features and accomplishments in the CPP field is virtually impossible. Hence this manuscript, after saluting the above 30th jubilee, focuses by necessity on the most recent contributions, providing a comprehensive list of recognized CPPs and their latest-reported applications over the last two years. In addition, it thoroughly reviews three areas of peptide vector research of particular interest to us, namely (i) efficient transport of low-bioavailability drugs into the brain; (ii) CPP-delivered disruptors of G protein-coupled receptor (GPCRs) heteromers related to several disorders, and (iii) CPP-mediated delivery of useful but poorly internalized drugs into parasites.

Abstract
The roles of microRNAs (miRNAs) in the regulation of metastasis have been widely recognized in the recent years. Mir-10b antagomir (antagomir-10b) was shown to impede metastasis through the down-regulation of mir-10b; however, it could not stunt the growth of primary tumors. In this study we showed that the co-delivery of antagomir-10b with paclitaxel (PTX) by a novel liposomal delivery system modified with an anti-microbial peptide [D]-H6L9 (D-Lip) could significantly both hinder the migration of 4T1 cells and induce evident cellular apoptosis and cell death in the meantime. The histidines in the sequence of [D]-H6L9 allowed the peptide to get protonated under pH5.0 (mimicking the lysosome/endosome environment), and strong membrane lytic effect could thus be activated, leading to the escape of liposomes from the lysosomes and the decrease of of mir-10b expression. The in vivo and ex vivo fluorescence imaging showed that D-Lip could reach 4T1 tumors efficaciously. Incorporation of PTX did not influence the antagomir-10b delivery effect of D-Lip; for the in vivo tumor inhibition assay, compared with all the other groups, the combination of antagomir-10b and PTX delivered by D-Lip could prominently delay the growth of 4T1 tumors and reduce the lung metastases at the same time, and the expression of Hoxd10 in tumors was also significantly up-regulated. Taken together, these results demonstrated that D-Lip could act as a sufficient tool in co-delivering antagomir-10b and PTX.
