Abstract

Objectives: Adoptive transfer of chimeric antigen receptor (CAR)-modified T cells is a form of cancer immunotherapy that has achieved remarkable efficacy in patients with some haematological cancers. However, challenges remain in CAR T-cell treatment of solid tumours because of tumour-mediated immunosuppression. Methods: We have demonstrated that CAR T-cell stimulation through T-cell receptors (TCRs) in vivo can generate durable responses against solid tumours in a variety of murine models. Since Clec9A-targeting tailored nanoemulsion (Clec9A-TNE) vaccine enhances antitumour immune responses through selective activation of Clec9A+ cross-presenting dendritic cells (DCs), we hypothesised that ..
