Description

Benjamin J. Tombling and co-authors built in 2026 small peptides that bind LRRC15, a protein found only on cancer support cells, for PET imaging of the tumour microenvironment. Support cells that aid tumours are hard to image directly. Yet their presence shapes treatment response and outlook.

Using a joined library aided by machine learning, the team made locked peptides, notably ML-YSD-07 and ML-PD-03. These bound murine LRRC15 with subnanomolar strength and homed to LRRC15-expressing support cells. PET imaging with fluorine-18-labelled ML-YSD-07 showed specific tumour build-up in a mouse pancreas cancer model rich in LRRC15 support cells. The peptides give a targeted imaging tool for tumours driven by their stromal backing.
