...d-type," p53 peptides in tumors. When presented on dendritic cells, these wild-type p53 peptides may induce an immune response to strengthen the body's natural defenses against cancer and decrease the chance of cancer recurrence and the formation of secondary tumors. "The key to our strategy is to select th...

Study finds novel vaccine curbs brain tumor growth, increases survival

...GFRvIII and compounds that stimulate immune system dendritic cells, which then activate the immune system in general and cytotoxic CD8 cells in particular. "It tricks the body into thinking that EGFRvIII is foreign, and the CD8 cells are sent in to kill the tumor," Heimberger says. After initial therapy - thr...
