Su Chul Jang et al. develop exoSTING, consisting of an engineered extracellular vesicle loaded with a potent cyclic dinucleotide (CDN) agonist of the STING pathway. They find that exoSTING shows more than 100-fold increased potency in in vivo tumor models and has increased tumor retention and lower levels of systemic inflammatory cytokine production as compared to free CDN.
