Du bist so schon!” Dann magst du mich in Fesseln schlagen, dann will ich gern zugrunde gehn! Johann Wolfgang von Goethe Faust I, 1699–1702 When, to the Moment then, I say: “Ah, stay a while! You are so lovely!” Then you can grasp me: then you may, Then, to my ruin, I'll go gladly! Johann Wolfgang von Goethe Faust I, 1699–1702 The author dedicates this textbook to the memory of Dr. Leonard Noon (St. Mary’s Hospital, Paddington/Imperial College London, United Kingdom), who helped millions of people with his revolutionary invention, allergen-specific immunotherapy. Preface The immune system is engaged in many fields related to health and illness, includ- ing allergy and nervous diseases, but can play both beneficial and harmful roles in the body. In many ways, it depends on the expression of either “good” or “bad” genes inherited from our ancestors. Such is the course of nature. Of course, our knowledge is still insufficient, but must respond to almost everyday attacks of aller- gens, microbes, tumor cells, and stress. These attacks continue to confront humans and well-being globally; in particular, a deep understanding of the immunologic mechanisms and processes will lead us to healthcare improvement. This manual is written at the interface of allergy, basic immunology, and neuro- science. It may be helpful for postgraduate medical students, clinical allergists, and researchers in fundamental allergy and neuroscience fields. The textbook has been set out in a logical order to allow the reader to understand the basic principles of the subject.
