WIRES Nanomedicine 2026 Review (Garland et al.): Peptide-Based Cancer Vaccines Materials, Targeting, and Delivery Strategies
A WIRES Nanomedicine and Nanobiotechnology 2026 review by Garland and colleagues synthesizes the materials-science side of peptide-based cancer vaccine development: lipid nanoparticle delivery, dendrimer scaffolds, peptide self-assembly platforms, and adjuvant chemistry. The piece complements the broader review wave by focusing on delivery and formulation rather than antigen selection. Key themes: lipid-nanoparticle-encapsulated peptides show improved bioavailability and immune-cell uptake versus free peptides; self-assembling peptide hydrogels enable sustained antigen release at injection site; CpG and TLR agonist combinations remain the dominant adjuvant approach but with new variants emerging. The review positions peptide vaccines as catching up to mRNA cancer vaccines (BioNTech, Moderna programs) on delivery sophistication.
