Research Field
Our research primarily focuses on the mutual interactions between innate/adaptive immune cells and the cancer cells, especially the cancer stem cells. We have discovered key mediators of cancer metastasis which also affect cancer stemness, therapy resistance, and immune evasion through patient-derived xenograft (PDX) technology and thus derived PDX metastasis models. We are intensively studying the immune regulation mechanisms underlying major immune/inflammatory diseases and cancer metastasis. As comprehensive cross-talks have been suggested among various systems in our body, i.e. immune system, endocrine system, nervous system, and tissue repair system in both normal and malignant conditions, we are evaluating the pathophysiological mechanisms of cancer metastasis and therapy resistance by accessing the cross-talks among different systems centering on body/tissue homeostasis system. Based on these studies, we are also focusing on the development of activatable, in situ, and neo-epitope targeting therapeutic cancer vaccines using state of art technologies, i.e. oncolytic virotherapy, exosome-mimetic nanovesicle therapy, and photodynamic immunotherapy to overcome therapy resistant cancer stem cells.
