This research engineers peptide-based "drug cages" that assemble like molecular zippers to deliver medicines only at their intended target. Inspired by natural protein structures, these programmable nanostructures could dramatically reduce chemotherapy side effects by releasing drugs precisely where needed, improving treatment effectiveness while protecting healthy tissues.

This research develops gold nanoparticles coated with peptides to block DNA repair in colorectal cancer cells, helping overcome drug resistance. Laboratory studies show the treatment dramatically reduces cancer cell survival after radiation while minimising toxicity. The approach could provide a safer, more effective therapy for colorectal cancer and other drug-resistant cancers.

This research uses a high-throughput screening platform called EpiScan to identify HIV peptides that bind strongly to MHC molecules and appear on infected cell surfaces. By discovering these immune-visible targets, the work aims to improve detection and elimination of hidden HIV reservoirs, supporting the development of future HIV therapies.

This research investigates how cells select which protein fragments, or peptides, to display to the immune system. Contrary to previous assumptions, peptide presentation appears highly curated rather than random. Understanding these selection rules could improve cancer immunotherapy, enhance antiviral treatments, and provide new insights into autoimmune diseases.
