As it usually occurs, the development of a scientific field is preceded by a stage that can be called ‘‘prehistory,’’ in which few primitive facts serve for claims that are not based on scientifically structured hypotheses and concepts. We have to admit that the ‘‘prehistoric’’ period in the field of immune–neuroendocrine interactions was a little bit too long, in which holistic statements such as ‘‘the brain and the mind control everything and then ... whynottheimmunesystem?’’predominated.Furthermore,theexperimentalevidence available at that time often derived from a primitive technology or from studies restricted to non-adaptive acute hypersensitivity and anaphylactic reactions. The most solid evidence of endocrineeffectsonimmunitywasthatadrenocorticalhormonesareanti-inflammatoryandcan affectimmuneorgansandthedistributionoflymphoidcells.SuchknowledgeledHansSelyeto predictthatstresscaninfluenceimmuneprocess,apredictionthatisatpresentfullyconfirmed and continuestobe investigatedin detail. Since then, an enormous bulk of information has accumulated indicating that the immune and neuroendocrine systems interact and control each other. Unfortunately, for some time, most immunologists were reluctant to accept the existence of a level of neuroendocrine control of immune processes. Retrospectively, this reluctancy is easy to justify since, at that time, it was still necessary to elucidate crucial intrinsic immune mechanisms. The main concern of immunologists was to understand the immune system from ‘‘within,’’ with a tendency to ignore that immune cells are also exposed to external signals that affect the system. To look ‘‘inside’’ the immune system yielded formidable results. Now, the structure of the main molecules (e.g., antibodies, T-cell receptor) that recognizes the huge universe of antigens is known. The molecular and genetic bases of the differentiation and diversification of immune cells as well as the types and subtypes of cells that participate in an immune response are largely understood. The biochemical pathways of immune cell activation and how these cells interact and receive information from antigen-presenting cells have also been clarified to a great extent. This knowledge showed that immune cells are extremely complex, and that refined interactions between them constitute the basis of different types of immune responses. The identification of efficient autoregulatory mechanisms may suggest that, compared to other physiologic systems, the immune system displays a privileged autonomy. However, a physiological immune response in an organism depends on mechanisms that are under neuro- endocrinecontrol.Themostobviouslevelofsuchdependenceistheneedtocontrolthehighly xiv Foreword demanding metabolic processes that underlie immune cell functions. Another example of dependence is relatedto the circulatorysystems. Indeed, no effective immune response would be possible if immune cells could not circulate and reach the places where antigens are presented. Hormones, neurotransmitters, and neuropeptides can also influence more refined mechanisms underlyingimmunecellactivity.Immunecellsperforminanenvironmentwherealltheseagentsare presentandcanperceiveneuroendocrinesignalsviaspecificreceptors.Thereisclearevidencethat immunecellscanestablishclosecontactswithnervefibersbothinlymphoidorgansandintissues wheretheymeetandrecognizeantigens,andexpandanddevelopaseffectorcells.Itisalsoknown thatcertainimmuneproductsandsomehormonesandneurotransmittersshearsecondintracellular messengers, transcription factors, and post-transcriptional mechanisms, a situation that allows a mutualmodulationoftheireffectsatintracellularlevels.Ontheotherhand,differenttypesofimmune cellsexpressadifferentnumberofreceptorsforagivenneuroendocrineagentandthisnumbervaries afteractivation.Thus,thedistinctsensitivityofrestingandactivatedcellstotheseagentscontributes toimmunospecificityandallowsaneuroendocrinecontrolofdefinedstepsoftheimmuneresponse. It is important to remark here that, under natural conditions, hormones, neurotransmitters, and neuropeptides represent the efferent messengers of complex immune–neuroendocrine regulatory circuits.Indeed,aswithothersystemsunderneuroendocrineregulation,theimmunesystemconveys signalstocentralregulatoryagenciesthatinturnrespondandaffectthecourse,development,and terminationoftheimmuneresponse.Thefirstneuroendocrineimmunoregulatorycircuitwaspostu- lated when it was shown that, following antigenic challenge, immune cell products stimulate the hypothalamus–pituitary–adrenal(HPA)axisandthattheresultingincreaseinglucocorticoidoutput can affect the immune response. The organization of this circuit and its relevance for health and diseaseisthemaintopicofthisvolume. The first chapter (A. Dunn) provides a general perspective of the content of this volume. Then,weconsidereditusefultoofferananatomicalandphysiologicaldescriptionoftheHPA axis (H. Vedder) and an analysis of how glucocorticoids can signal during health and disease (K.SmoakandJ.Cidlowski).Becauseofitscomplementaryphysiologicalfunctioningwiththe HPA axis, the organization of the sympathetic nervous system is included (W. Ja¨nig). Also a briefdescriptionoftheinnate(K.Heeg)andspecific(I.LefkovitsandL.DuPasquier)immune responses, as well as how the immune system functions in the brain (T. Jones, K. Lucin, and P.Popovich),ispresented.Thesecondpartofthisvolumeisdevotedtoeffectsandmechanisms of action of glucocorticoids on immune processes (P. Guyre, M. Yeager, and A. Munck), including their effects on the developing thymus (R. Sacedo´n et al.). The action of catechol- amines (I. Elenkov) on immunity and the dual suppressive and enhancing effects of stress on immunefunction(F.Dhabhar)arealsocoveredinthispart.Thethirdpartofthisvolumedeals with afferent signalsdeliveredtothe brain,endocrineglands,andtheautonomic nervesystem duringimmuneresponses.HowimmunesignalsareprocessedatbrainlevelandaffecttheHPA axis(H.BesedovskyandA.delRey),andtheeffectofinflammatorymediatorsonthepituitary (D. Giacomini et al.), the adrenal glands (I. Vrezas et al.), and the autonomic nervous system (R. Straub et al.) are addressed here. The last part covers the clinical relevance of HPA axis– immune interactions, particularly during sepsis and the multiple organ dysfunction syndrome (I. Vermes and A. Beishuizen) and inflammatory disorders (J. Webster Marketon and E. Sternberg). The development of glucocorticoid resistance during inflammatory diseases (D. Franchimont and G. Chrousos) and the role of glucocorticoids in asthma (P. Barnes) are also discussed. We hope that this volume provides a comprehensive view of the molecular and functional organization oftheimmune–HPAaxiscircuitanditsclinicalrelevance.We alsoexpectthatit
