Charles A. Janeway, Jr. Diane Martindale dmartindale writescience. He was 60 years old. After earning his medical degree from Harvard Medical School in , Janeway joined a long family line of prominent physicians, which included his great great-grandfather, Edward Janeway, who was a New York City health commissioner. In , he was promoted to a professor of pathology, and in , he became one of the founding members of the newly created section of immunobiology at Yale University School of Medicine.
By this, Janeway meant the requirement for adjuvants, notably those containing bacteria or bacterial extracts, in order to generate immune responses. The adjuvants stimulate phagocytes, which are the cells of the innate immune system that recognize conserved and distinctive features of pathogens.
Unless phagocytes are stimulated, there is no adaptive immune response. This formed the basis of his thinking about the role of costimulatory signals in inducing immune responses. By , Janeway correctly predicted that pattern recognition receptors are what allow cells of the innate immune system to recognize pathogens directly. From his insights, said Paul Travers, deputy director of the Anthony Nolan Research Institute in London and co-author of the Immunobiology textbook, immunologists ultimately came to the role of dendritic cells a type of phagocyte that can present antigens to T cells and the nature of the dialogue between T cells and dendritic cells that shapes the immune response.
One of his proudest achievements was his textbook, which is now in its fifth edition and the leading textbook in immunology. The first edition took seven years to write. Friends, family, and colleagues called him Charlie and knew him as a man who took great pride in training his students, many of whom are now professors in immunology departments around the world. His trademark look was a red pixie hat, which he wore everywhere. Despite this wayward look, Janeway was hugely intelligent and fearlessly outspoken.
Those who knew him agree that Janeway was most brave about his illness. Diagnosed in with the cancer that eventually took his life, he had huge energy and vitality, which even a long and debilitating illness could not subdue for many years. Charlie never gave up. Related Articles.

Dr. Charles Janeway Jr., 60, Expert on Immune System, Dies
Janeway Jr, professor of immunobiology at Yale University School of Medicine in New Haven and one of the pre-eminent modern immunologists, died on 12 April of lymphoma. Most scientists only dream of contributing to a paradigm shift — Janeway personally initiated one. He reasoned that there must be mechanisms to ensure that an immune response is not only specific, but is also appropriate. Now, it is one thing to have a great idea and another to prove it. With Ruslan Medzhitov, a postdoctoral fellow and then colleague at Yale, Janeway showed that mammalian relatives of the Toll protein — a key player in the inflammatory response in fruitflies — constitute one set of pattern-recognition receptors. Indeed, we now know that the Toll-like receptors recognize a wide array of structures associated with various pathogens, including lipopolysaccharide found in the cell wall of many bacteria and double-stranded RNA. Recognition of these molecules by key components of the innate immune system, notably dendritic cells, sets off intracellular signals that equip the cells to direct the priming and differentiation of cells of the adaptive immune system.

The humoral immune response is initiated when B cells that bind antigen are signaled by helper T cells or by certain microbial antigens alone Armed helper T cells activate B cells that recognize the same antigen Antigenic peptides bound to self MHC class II molecules trigger armed helper T cells to make membrane-bound and secreted molecules that can activate a B cell Isotype switching requires expression of CD40L by the helper T cell and is directed by cytokines Antigen-binding B cells are trapped in the T-cell zone of secondary lymphoid tissues and are activated by encounter with armed helper T cells
