Abstract: Polymer Journal, Published online: 16 June 2026; doi:10.1038/s41428-026-01212-2We developed pH-responsive amphiphilic peptide nanofibers (NFs) that may facilitate cytosolic protein delivery by selectively destabilizing endosomal membranes. The NFs were based on β-sheet-forming peptides conjugated with oligoglutamic acid segments, and the number of Glu residues was varied to optimize pH-responsive activity. Optimized NFs showed strong membrane-destabilizing activity at mildly acidic pH but remai[...]


Our summary: The study presents pH-responsive amphiphilic peptide nanofibers designed to enhance cytosolic protein delivery. These nanofibers destabilize endosomal membranes at mildly acidic pH while remaining stable at neutral pH. When tested with ovalbumin in dendritic cells, they improved MHC class I presentation of the OVA-derived epitope.
