Peptide therapy enhances targeted medicine by providing a modular by M Liu·2021·Cited by 113—Receptor-targeting peptideshave been extensively pursued for improving binding specificity and effective accumulation of drugs at the site of interest, platform for discovery. The design, discovery, and evolution of peptide-based targeting agents have moved from simple discovery methods to complex, computer-aided designs. We are now seeing the use of tumor-targeting peptides that can distinguish between healthy and diseased tissue based solely on the density of peptide-binding receptors for anti-cancer drug delivery.
Furthermore, the design concepts and methods of targeting peptides have expanded into the realm of molecular imaging, where these molecules act as probes to provide real-time data on biological processes.
Why This Field Matters
From my perspective, the shift toward using peptides to target over or exclusively expressed receptors in cancer cells represents a major leap in efficiency. Because peptides are strong candidates for immunotherapy, they are being studied for their ability to modulate immune responses effectively.
Whether we are looking at peptidic ligands or complex receptor-targeting peptides, the fundamental goal remains the same: to learn how targeting peptides enhance selectivity and efficiency. As we continue to refine these peptide-based strategies, the potential for high-precision applications—ranging from diagnostics to advanced delivery platforms—continues to grow.
