Caption

Immune cells in the spleen have brought in stowaways: Listeria bacteria, which appear green in the image. Researchers at Washington University School of Medicine in St. Louis have found that the immune cells the bacteria have exploited can be both helpful and harmful in fighting infection. The cells could be particularly useful in efforts to turn the immune system against cancers using vaccines.
