Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to the Special Issue “State of the Art of Membrane Active Peptides, 2nd Edition”. This issue is focused on membrane-active peptides that interact with the cell membrane and exert their biological activity by delivering different molecules inside cells or by disrupting the membrane followed cell lysis. Cell-penetrating peptides (CPPs) surmount the membrane barrier and deliver a great number of cargoes into the cells. CPPs act by the direct translocation of the membrane, pore formation or by endocytic routes. Antimicrobial peptides (AMPs) are components of the innate immunity and serve as first line protection against pathogens. Nowadays, multidrug-resistant bacteria to available antibiotics represent a major challenge, and AMPs are used to create a new generation of antibacterial drugs. Antimicrobial peptides target the bacterial membrane and lyse it using different mechanisms, such as the toroidal pore, the carpet model or the barrel stave model. Membrane-active peptides are considered as promising alternatives to current pharmaceuticals. However, their therapeutic potential is restricted by the current understanding of their molecular mechanism of action.

This Special Issue aims to bring together the latest advances regarding the molecular mechanism of peptide internalization, techniques to reveal these modes of peptide uptake and develop new peptide sequences, biological activity, applications and clinical data.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

  • Molecular mechanisms of membrane-active peptides;
  • Techniques to reveal the molecular mechanisms of membrane-active peptides;
  • Recent advances in applications of membrane-active peptides in biotechnology and medicine;
  • New peptide sequences and their biological activity;
  • Drug delivery systems based on membrane-active peptides.

We look forward to receiving your contributions.

Antibiotic resistance poses a serious threat to public health globally, reducing the effectiveness of conventional antibiotics in treating bacterial infections. ESKAPE pathogens are a group of highly transmissible bacteria that mainly contribute to the spread of antibiotic resistance and cause significant morbidity and mortality in humans. Phylloseptins, a class of antimicrobial peptides (AMPs) derived from Phyllomedusidae frogs, have been proven to have antimicrobial activity via membrane interaction. However, their relatively high cytotoxicity and low stability limit the clinical development of these AMPs. This project aims to study the antimicrobial activity and mechanisms of a phylloseptin-like peptide, phylloseptin-TO2 (PSTO2), following rational amino acid modification. Here, PSTO2 (FLSLIPHAISAVSALAKHL-NH2), identified from the skin secretion of Phyllomedusa tomopterna, was used as the template for modification to enhance antimicrobial activity. Adding positive charges to PSTO2 through substitution with L-lysines enhanced the interaction of the peptides with cell membranes and improved their antimicrobial efficacy. The analogues SRD7 and SR2D10, which incorporated D-lysines, demonstrated significant antimicrobial effects against Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) while also showing reduced haemolytic activity and cytotoxicity, resulting in a higher therapeutic index. Additionally, SRD7, modified with D-lysines, exhibited notable anti-proliferative properties against human lung cancer cell lines, including H838 and H460. This study thus provides a potential development model for new antibacterial and anti-cancer drugs combating antibiotic resistance. Full article

Biosimilars represent medicinal products that exhibit a high degree of similarity to an already sanctioned reference biologic agent, with negligible clinically significant disparities concerning safety, purity, or potency. These therapeutic modalities are formulated as economically viable substitutes for established biologics, thereby facilitating increased accessibility to sophisticated treatments for a range of medical conditions, including infectious diseases caused by bacterial, fungal, and viral pathogens. The current landscape of biosimilars includes therapeutic proteins, such as monoclonal antibodies, antimicrobial peptides, antiviral peptides, and antifungal peptides. Here, we discuss the obstacles inherent in the development of biosimilars, including the rapid mutation rates of pathogens. Furthermore, we discuss innovative technologies within the domain, including antibody engineering, synthetic biology, and cell-free protein synthesis, which exhibit potential for improving the potency and production efficiency of biosimilars. We end with a prospective outlook to highlight the importance and capacity of biosimilars to tackle emerging infectious diseases, highlighting the imperative need for ongoing research and financial commitment.

Peptides possess a number of pharmacologically desirable properties, including greater chemical diversity than other biomolecule classes and the ability to selectively bind to specific targets with high potency, as well as biocompatibility, biodegradability, and ease and low cost of production. Consequently, there has been considerable interest in developing peptide-based therapeutics, including amyloid inhibitors. However, a major hindrance to the successful therapeutic application of peptides is their poor delivery to target tissues, cells or subcellular organelles. To overcome these issues, recent efforts have focused on engineering cell-penetrating peptide (CPP) antagonists of amyloidogenesis, which combine the attractive intrinsic properties of peptides with potent therapeutic effects (i.e., inhibition of amyloid formation and the associated cytotoxicity) and highly efficient delivery (to target tissue, cells, and organelles). This review highlights some promising CPP constructs designed to target amyloid aggregation associated with a diverse range of disorders, including Alzheimer’s disease, transmissible spongiform encephalopathies (or prion diseases), Parkinson’s disease, and cancer.
