Wnt1 silences chemokine genes in dendritic cells and induces adaptive immune resistance in lung adenocarcinoma

Abstract

The Wnt pathway regulates anti-tumour immunity in melanoma. Here, the authors show that, in lung adenocarcinoma, secretion of the ligand Wnt1 induces immune resistance by impairing the ability of dendritic cells to cross-prime T cells, and that blocking Wnt signalling enhances rejection of tumours by acting both on the cancer and immune cells.
