As our understanding of biological systems and human diseases advance, humans are now trying to combat cancer with new development of drugs and therapeutic treatments. An aspect that scientists are working on is the development of personalized cancer therapies to train our immune system to recognize and target our own cancer cells. The Wang Lab has developed a new personalized cancer therapy. It is a cancer vaccine that makes cancer-cell derived exosomes more effective antigens for targeting specific tumors. This way, we can get a better chance at utilizing these particles to boost our T cells and Dendritic cells to fight against cancer.
