A toll-like receptor agonist mimicking microbial signal to generate tumor-suppressive macrophages

Abstract

Turning tumour promoting macrophages into an anti-tumour phenotype is an attractive therapeutic strategy. Here, the authors develop a polysaccharide-based structure that mimicks pathogen-associated molecular patterns and, by activating the toll-like receptors on macrophage surface, promotes a safe anti-tumour immune response in mouse models.
