Improved nano-sized cell particles discovered to enhance cancer immunotherapy and reduce side effects
Electron micrograph of artificial extracellular vesicles (magnification 23,000x). Courtesy: NUS Yong Loo Lin School of Medicine Immunotherapy is a type of cancer treatment that uses the body’s own immune system to fight cancer. It stimulates an immune response to more effectively recognize and attack cancer cells. Treatments may involve using substances to boost the immune system, teaching immune cells to…
