Preface
V
How do you discriminate yourself from other people? This question must sound odd to you since you easily recognize others at a glance and, without any effort, would not mistake them for yourself. However, it is not always easy for some people to discriminate themselves from others. For example, patients with schizo-phrenia often talk with “others” living inside themselves. Thus it is likely that nor-mally your brain actively recognizes and remembers the information belonging to yourself and discriminates it from the information provided by others, although you are not conscious of it. This brain function must have been particularly important for most animals to protect their lives from enemies and for species to survive through evolution. Similarly, higher organisms have also acquired their immune system through evolution that discriminates nonself pathogens and self-body to protect their lives from pathogens such as bacteria or viruses.
The brain system may distinguish integrated images of self and nonself created from many inputs, such as vision, sound, smell, and others. The immune system recognizes and distinguishes a variety of structural features of self and nonself components. The latter actually include almost everything but self: for example, bacteria, viruses, toxins, pollens, chemicals, transplanted organs, and even tumor cells derived from self-tissue. To this end the immune system recruits different kinds of immune cells, such as B and T lymphocytes, natural killer (NK) cells, dendritic cells, and macrophages. These cells have specifi c functions and are equipped with distinctive sets of receptors to recognize self and/or nonself compo-nents. B and T lymphocytes have characteristic antigen receptors whose binding specifi cities are extremely diverse among individual cells. This diversity is gener-ated through somatic rearrangement of the genes encoding the antigen receptors. The repertoires of the diverse antigen receptors cover a huge variety of self and nonself antigens, which normally results in tolerance to self antigens and the immune responses to the nonself antigens including antibody production, T-cell-mediated cytotoxicity, and infl ammation. The antigen recognition signal is critically regulated by activating or inhibitory co-receptors on the same cells. The antigens are also recognized by specifi c antibodies bound with Fc receptors on various immune cells. NK and NKT cells express collectively what are called NK receptors
composed of various pairs of receptors, one recognizing a specifi c viral or neoplas-tic antigen and the other self MHC (major histocompatibility complex) antigen on the self cells, and the pair work together to discriminate a target to kill. In addition to the NK receptors, a growing number of the paired immunoglobulin-like receptors have been identifi ed. Finally, Toll-like receptors expressed on the cells such as dendritic cells and macrophages recognize various structural patterns of pathogens to eliminate them as the fi rst defense and also to regulate the immune response by lymphocytes. Single mutations in some of these receptors or their downstream signaling molecules are known to cause autoimmune diseases in mice or humans, suggesting that functions of those immune cells expressing a different set of recep-tors are highly integrated and cooperate in an immune system to decide what is self and what is nonself.
In contrast to the extreme diversity of the receptors, the molecules involved in the signaling from such receptors is relatively limited and often is shared among different receptor systems. Therefore, the immune cells may use a common strategy for processing the signals from these receptors and for making a decision about their next action. The aim of this book is to try to clarify how the immune cells recognize through receptors a diversity of targets, being either self or nonself, how they translate this recognition into signals and transmit the signals, and how fi nally they decide to react or not to play a part in the immune response. For this purpose, an extensive and updated review on each receptor system is described in each chapter by an expert in that area. Although our knowledge is still far from complete, this challenge will give you many clues to discover the principle of the signaling machinery and to understand the complexity of cell interaction through receptor signaling in the immune system. Thus this book will help you to imagine the basic strategy of the immune system to distinguish self and nonself. I believe this chal-lenge is particularly important for basic as well as clinical immunologists who are seeking a breakthrough in the regulation of immune diseases such as autoimmunity and allergy. Also, the concept and strategy of self–nonself discrimination in the immune system might be applied to the brain system as briefl y mentioned above, or as a security system of a computer network.
I would like to thank all the authors for their invaluable contributions and their patience.
