Dr. Edith Janssen currently serves as the Associate Scientific Director for Immunology at Janssen Pharmaceuticals, a division of Johnson & Johnson. Dr. Janssen is an expert in innate immunology. She collaborated with Dr. Bruce Beutler (Nobel Prize in Medicine, 2011) to understand the relationship between innate and adaptive immunity, which had historically been viewed as separate entities. The novel concept of innate-adaptive immune interaction has contributed significantly to the optimization of vaccines, cancer therapies, and therapies targeting autoimmunity, transplantation, and infection. Her pioneering work in defining the role of CD4+T cell in CD8+T cell priming and memory development, a long-standing paradox in cellular immunology was published in Nature and Nature Immunology.
