New nanoparticles boost immune system in mice to fight melanoma and breast cancer

Researchers from Vanderbilt University, Yale University, Northwestern University, and AstraZeneca have developed a set of nanoparticles that stimulate the immune system in mice to fight cancer and may eventually do the same in humans. The nanoparticles delivered a nucleic acid molecule that triggers an immune response that is normally used by the body to recognize foreign viruses to help the immune system mount a defense, according to the researchers.
