Tumour-antigen-pulsed mature dendritic cells (DC) have not been as efficient for cancer therapy as hoped to be, due to their sub-optimal antigen-presentation and migration capacities. Here the authors utilise DC progenitors, constitutively expressing IL-12 and an engineered extracellular vesicle-internalizing receptor (EVIR), which give rise to mature conventional type 1 DCs with improved antigen presenting capacities, resulting in improved anti-tumour immunity in a mouse model of melanoma.
