by Stanford University Credit: Pixabay/CC0 Public DomainSome cancerous tumors hijack proteins that act as “brakes” on our immune system and use them to form a sort of shield against immune recognition. Immunotherapy treatments have been created that turn off these “brakes” and allow our body to attack foreign-looking cancer cells. To further advance such treatments,...
