Abstract Insect neuropeptides and peptide hormones have been the subject of research for more than a century, evolving from early bioassays with crude extracts to modern genomic and structural approaches. Initially discovered as mysterious regulators of molting and reproduction, these small signaling molecules are now recognized as master regulators of insect physiology. They govern essential […]
A New Twist in Viral Gene Delivery Gene therapy holds the promise of treating diseases at their source by rewriting faulty genetic instructions. Central to this approach are retroviral vectors—viruses repurposed to deliver therapeutic genes into human cells. Despite their potential, one major hurdle remains: getting these vectors to efficiently attach and enter target cells. […]
Abstract Targeted protein degradation (TPD) has revolutionized modern drug discovery, yet plasma membrane proteins—critical in cancer, immunity, and metabolism—have remained stubbornly difficult to degrade. Traditional PROTACs act only on intracellular targets, while lysosome-based systems like LYTACs depend on tissue-specific receptors and suffer from efficiency limitations. A recent Nature Communications study introduces a novel solution: Cell-Penetrating […]
Abstract Peptide self-assembly has traditionally been understood through the framework of an “assembly code,” in which the primary sequence is thought to dictate supramolecular architecture. While this concept has enabled rational design of predictable nanostructures, growing evidence demonstrates that peptide assembly is profoundly context-dependent. Environmental variables—including pH, ionic strength, solvent conditions, and molecular crowding—reshape assembly […]
Abstract Metabolic dysfunction–associated steatohepatitis (MASH) represents the progressive and clinically significant form of metabolic dysfunction–associated steatotic liver disease (MASLD), a condition now recognized as the most common cause of chronic liver disease worldwide. Closely linked to obesity, type 2 diabetes mellitus, and cardiovascular morbidity, MASH carries a substantial risk of cirrhosis, hepatocellular carcinoma, and mortality, […]
Abstract Hydrogels such as gelatin methacryloyl (GelMA) hold great promise for regenerative medicine, offering biocompatibility, photocurability, and adaptability for in situ repair and 3D bioprinting. Yet, their inherent brittleness limits performance in load-bearing applications like cartilage and bone regeneration. Inspired by the mechanical resilience of intervertebral discs, researchers have developed a reinforcement strategy using peptide-based […]
Abstract Antimicrobial peptides (AMPs) are promising candidates for combating multidrug-resistant pathogens, yet their therapeutic potential is often limited by host cytotoxicity and proteolytic instability. This study focuses on Esculentin-1a(1–21)NH₂ [Esc(1-21)], a frog-skin–derived AMP with potent Gram-negative activity, and explores a novel optimization strategy: site-specific incorporation of an isopeptide bond at selected lysine residues. Five analogs […]
Abstract As cancer therapies evolve, precision and adaptability have become critical. Peptide-functionalized nanoparticles are emerging as next-generation tools that combine the targeting accuracy of peptides with the delivery efficiency of nanomaterials. These smart systems enable selective drug, gene, and natural product delivery to tumors while minimizing off-target effects. Peptides serve not only as targeting ligands […]
Abstract Cosmetic peptides are rapidly transforming the landscape of anti-aging skincare. These short chains of amino acids offer targeted benefits by stimulating collagen production, promoting skin healing, and minimizing muscle contractions that lead to wrinkles. This blog explores the four main types of peptides—signal, carrier, neurotransmitter inhibitors, and enzyme inhibitors—highlighting their unique roles in skin […]
Abstract Peptide-based therapeutics are emerging as powerful tools across a wide range of medical fields, including metabolic disease, cancer, and infectious disease. Once limited by poor stability and challenging delivery, modern peptides are now benefiting from advanced engineering, smart delivery platforms, and precision targeting strategies. This blog explores how structural modifications, such as cyclization and […]
