On today's show, we listen back to a StudioTulsa on Health broadcast from October of last year. At that time, guest host John Henning Schumann spoke with Daniel M. Davis, a Professor of Immunology at the University of Manchester in the UK. The focal point of this discussion was the then-new book that Dr. Davis had out from Oxford University Press, "The Compatibility Gene: How Our Bodies Fight Disease, Attract Others, and Define Our Selves." As was noted of this title in The New York Times, in that newspaper's science section: "[It] will enhance most readers' appreciation for the immune system's heroic daily struggles to prevent their body from being overrun by alien life-forms. The book also explores the immune system's reach into realms as unexpected as choosing a mate, wiring the brain, and determining the success of pregnancies.... [Davis] not only writes gracefully but has taken the trouble to interview the major players in [immunology] about how they made their discoveries. His book is enlivened by many details one would not find in an immunology textbook. Which famous immunologist was into sadomasochism? Which told his wife she had first claim on his love but not on his time? Which one wrote a letter to his deceased wife every week? Read all about it here.... The exact nature of the relationship between the brain and the immune system is far from clear, and Davis does a good job of explaining the nuances.... [His] readable and informative book takes the reader into unexpectedly interesting corners of both the immune system and the lives of immunologists. It is packed with an insider's knowledge --- not just of the field, but of where its bodies are buried."
