Tumor‐derived exosomes elicit tumor suppression in murine hepatocellular carcinoma models and humans in vitro
Quan Rao, Bingfeng Zuo, Zhen Lu, Xianjun Gao, Abin You, Chenxuan Wu, Zhi Du, HaiFang Yin – 17 March 2016 – Hepatocellular carcinoma (HCC) remains a global challenge due to high morbidity and mortality rates and poor response to treatment. Immunotherapy, based on introduction of dendritic cells (DCs) activated by tumor cell lysates as antigens ex vivo, shows limited response rates in HCC patients. Here, we demonstrate that tumor cell–derived exosomes (TEXs), displaying an array of HCC antigens, can elicit a stronger immune response than cell lysates in vitro and in vivo.
