Prof. Cai has long been engaged in research on extracellular vesicles (EVs) and immunity, and has achieved a series of original results. He and his team:
(1) revealed a new mechanism of immunosuppression induced by extracellular vesicles after chemotherapy.
(2) showed a new mechanism for the body to maintain lung and intestinal immune balance mediated by extracellular vesicles.
(3) found a new method for the treatment of autoimmune diseases using exosomes (exosomes, one of EVs) derived from dendritic cells (DCs) modified by immunosuppressive genes.
(4) discovered a new mechanism by which tumor cell-derived exosomes promoted tumor metastasis by domesticating DCs, revealed a new mechanism by which exosomes mediated tumor metastasis via Fas signaling.
(5) discovered serum CD19-positive exosomes could be found to screen early tumors.
(6) found the new function of autophagy in regulating TH9 cell differentiation and the important role of CD69 in maintaining Treg immunosuppressive function.
Recently, the topics that his research group is working on are as follows:
1. Protein neddylation modification regulates exosomes release;
2. Thoracic injection of tumor cell-derived exosomes inhibits lung tumors;
3. Study on the treatment of Her2 positive tumors with engineered exosomes;
4. FBXW7-mediated TH17 cell differentiation participates in bowel inflammation;
5. Study on how TH9 cell exerting its antitumor activity.
