Janeway's
Immunobiology is intended for undergraduate and graduate courses in immunology,
as well as for medical students. The book can be used as an introduction to
immunology but its scope is sufficiently comprehensive and deep to be useful
for more advanced students and working immunologists. Immunobiology presents
immunology from the consistent viewpoint of the host's interaction with an
environment full of microbes and pathogens, and illustrates that the loss of
any component of this system increases host susceptibility to some particular
infection. The companion book, Case Studies in Immunology, provides an
additional, integrated discussion of clinical topics (diseases covered in Case
Studies are indicated by a symbol in the margin of Immunobiology).
This eighth
edition retains the overall organization of the previous edition, and chapters
in which the field has made important and rapid developments have been
extensively revised. The discussion of innate immunity has been substantially
expanded and its mechanisms are now treated in two separate chapters, presented
in the order in which a pathogen would encounter innate defenses as it attempts
to establish an infection. The immediate and soluble defenses are treated in
Chapter 2. The complement system is introduced in the context of innate
immunity, with the lectin pathway presented before the classical pathway of
activation. The induced defenses of innate immunity-including a completely
updated treatment of innate sensing-follows in Chapter 3, where various innate
cell subsets and their receptors are also described. Signaling pathways are now
presented as they are encountered, and not confined to a single chapter.
Signaling pathways of the Toll-like receptors and other innate sensors are
described in Chapter 3, while antigen receptor signaling pathways and cytokine
and apoptotic pathways are retained in Chapter 7. Chapter 10 has been revised
to place more emphasis on the trafficking of B cells in peripheral lymphoid
organs and the locations at which they encounter antigen. Mucosal immunology
(Chapter 12) has been expanded to include more discussion of responses to the
commensal microbiota and the role of specialized dendritic cells and regulatory
T cells in maintaining tolerance to food antigens and commensal bacteria. The
last four chapters-the clinical chapters Chapters 13-16)-reinforce the basic
concepts discussed earlier with our latest understanding of the causes of
disease, whether by inherited or acquired immunodeficiencies or by failures of
immunological mechanisms. Chapter 16 describes how the immune response can be
manipulated in attempts to combat infectious diseases, transplant rejection,
and cancer. This chapter includes a complete update of the immunotherapeutics
and vaccine sections. Aspects of evolution, which were confined to the last
chapter of previous editions, are now discussed throughout the book as the
relevant topics are encountered.
