Etty Benveniste Copyright © 2006 Taylor & Francis Group, LLC 1622_C000.fm Page vii Wednesday, September 7, 2005 5:16 PM Preface It has been almost exactly 10 years since we began work on the first edition of this book. We were strongly motivated by the explosive growth in knowledge about cytokines/chemokines and cytokine/chemokine signaling, and the potential for appli- cation of this information to understanding the development, physiology, and pathology of the central nervous system (CNS). Our efforts were gratified by considerable interest in the book, which remains in print today (selling three units in the first half of 2004). Using the prosaic descriptor afforded by counting PubMed citations (“Cytokines” AND “Central Nervous System”), there were 2225 papers in this field during more than 28 years captured in the current PubMed index (from 1966 to September 1994), with less than 1000 in the period 1966–1989 and 1244 (56%) appearing in the five years before our first edition (1989–1994). Indeed, the MESH entries for “cytokine” (1991) and “cytokine receptor” (1994) were then still newly- minted. Since then, the pace has only accelerated, with another 6189 papers (74% of all articles on the subject) in the past 10 years, meaning that, during the past decade, every 18 months brought on average as many reports in this field as in the first 23 years. The first edition was organized to present information that would serve overlap- ping purposes for neurobiologists, immunobiologists, and other interested parties. Basic cytokine biology (receptors, signaling, cellular responses) took up the first three chapters, with the fourth devoted to introducing the unique cellular elements of the CNS. Three chapters addressed how these CNS cells respond to cytokine stimulation, with the last six addressing how cytokine interactions play out in the setting of CNS pathology. When preparing the first edition, our feeling was that cytokine biology needed an introduction to neurobiologists for two reasons: (1) receptor structure and post- receptor signaling had achieved a level of coherence and mechanistic detail that could be readily communicated; and (2) there was enough similarity (at times identity) between factors involved in inflammation or immunity and those implicated in neural development, physiology, and repair that familiarity with cytokines was an essential element in the neurobiologist’s cognitive tool kit. Conversely, for immunobiologists, the concepts elaborated on by neurobiologists to understand developmental pattern- ing and networked organ function were so elegant that comprehension of cytokine action in the CNS could only enhance appreciation of ways the immune system might work. These principles remain unaltered. The design of this second edition embraces three chapters on basic cytokine biology, following one chapter on the CNS (cells, tissues, basic pathological reactions to insult). Next are four chapters that integrate cytokine biology into basic CNS processes (development, inflamma- tion, immunity, degeneration/repair). There are five chapters that apply this body of knowledge to disease or pathology (neurodegeneration, neoplasia, multiple sclerosis, Copyright © 2006 Taylor & Francis Group, LLC 1622_C000.fm Page viii Wednesday, September 7, 2005 5:16 PM trauma, infection). Finally, we look forward in a last chapter to the translation of cytokine biology to treatment, an entirely new and welcome topic. Fortunately, the organizing concepts for the first volume remain largely valid. We put forth that the newly-proposed notion of grouping cytokines according to receptor structure would be enduringly useful, and the groups I and II cytokine receptors were presented as illustrative examples. The ongoing utility of this approach can be deduced from following the expanding (but not exploding) field of interleukins. Our first volume indexed 10 interleukins; there are now at least 29. Reassuringly, the newer interleukins fall into families defined by older members (for example, IL-22, IL-24, IL-26, IL-28 and IL-29 are members of the IL-10 family; IL-23 is a member of the IL-12 family; IL-25 is a member of the IL-17 family; and IL-27 is an IL-6 family member), forestalling a bit of ‘shock of the new.’ Remarkably, the families remain functionally defined, as proposed more than a decade ago, by shared receptor subunit utilization. Challenges to usable core memory remain, how- ever: Online Mendelian Inheritance in Man (OMIM) lists no less than 18 TNF superfamily ligands (TNFSFs), signaling to 25 receptors (TNFSFRs). This nomen- clature has been adopted haltingly and spottily, making the relevant literature dense for the casual user. Nevertheless, the critical importance of this group of molecules for neuroimmunology (comprising components such as the p75/LNGFR in addition to TNF, its receptors; Fas and FasL; CD154 and CD40) dictates that the effort must be made. Ready availability of Web-based resources is a welcome aide memoire, growing at about the same pace as new nomenclatures and molecules. The current edition of Cytokines and the CNS is therefore continuous with its predecessor. However, in another sense, it is entirely original, since each chapter was prepared by a new contributor. This evolutionary change was not dictated by any one of the previous authors leaving the field, but rather by our desire to have a fresh look at each topic. The chapters of this second edition cover much of the same ground as previously, but focus more on processes (immunity, inflammation, devel- opment) than individual cell types (oligodendroglia, astrocytes; neurons). The major pathological processes that concern us today (infection, trauma, neurodegeneration; multiple sclerosis) are those discussed previously. We are endlessly grateful to our contributors, whose scholarship and hard work were continuously amazing, and hope that their efforts translate seamlessly to benefit for readers. The advance of knowl- edge in these fields will be apparent to cursory comparison of the first and second editions. Tasks that remain undone are formidable indeed: foremost among them is to understand how cells and tissues integrate simultaneous or sequential multiple cytokine signals to produce biological outcomes. These types of questions demand new methods of analysis, for which the very first drafts have only recently been described. We hope that the biology described in the current book helps to persuade the contemporary and future community of CNS/cytokine researchers that the goal is worth the effort.
