Book Description
The Fifth International Lymphokine Workshop was convened in Clearwater Beach, Florida, January 11-15, 1987. The theme chosen for the meeting was 'The Molecular Basis of Lymphokine Action," which reflected the opinion of the organizers as to how far the field had moved since the first Lymphokine Workshop only eleven years ago. As was evident at the last Lymphokine Workshop held in 1985, the contribution of molecular biology, particularly in the cloning of lymphokine genes, continues to play an important role in clarifying the structure of lymphokines, providing recombinant (read "pure") proteins for biological studies, and suggesting directions for studies of the molecular basis of lymphokine activity. The most recent lymphokines to yield to molecular cloning meth odology were the B-cell growth and differentiation factors, in partic ular BSF-1 or, as it is sometimes termed, interleukin 4. One of the surprises from this research is the broad spectrum of activities that can be attributed to this molecule, aside from its effects on B-cells, thus perhaps justifying its being called an interleukin. The interleukin 2 symposium demonstrated that even in a well-established research area, controversy and excitement can continue, when evidence was presented by several investigators indicating the presence of a second "converter" protein that changes the affinity of the now classical Tac antigen from a low to a high affinity IL-2 receptor.

Book Description
Biology of the Lymphokines discusses the scope and diversity of lymphokine research. This book focuses on the studies on lymphokines, such as those involving cellular source, chemical nature, purification strategies, and bioassay limitations. The mechanism of lymphokine action, lymphokines in vivo, and value of lymphokine quantitations are also covered. This text describes the repertoire of lymphokines produced by various lymphoblastoid cell lines and its significance for coping with the problem of large scale lymphokine production. The anti-viral and general immunoregulatory properties of interferons and rationale developed for integrating interferons with the family of lymphokines are likewise deliberated. This publication is a good source for students and researchers conducting work on lymphokines.

Book Description
Cytokines are regulatory polypeptides synthesized by a variety of cells in response to injury, inflammation or infection and which act on different tissues by changing gene expression and cellular metabolism. This book provides the results from recent in vitro studies of the structure and function of various cytokines. It offers an up-to-date overview of the latest advances in cytokine research, including research developments dealing with colony stimulating factors, interferons and growth and differentiation factors - as well as classical hormones such as insulin, neurokinin, somatomedin and parathormones. Several newly identified cytokine receptor structures are also discussed, as are certain activities of the recently discovered 8,000-10,000 m.w. cytokine family.

Book Description
Human Lymphokines: The Biological Immune Response Modifiers is a collection of papers presented at the Third International Symposium on Human Lymphokines held on October 15-17, 1981 at the Wadley Institutes of Molecular Medicine in Dallas, Texas. Contributors explore the role of human lymphokines in immune responses and their applications in immunotherapy. The focus is on lymphokines that have either entered clinical trials or are nearing clinical evaluation. Some of the activities of possible immediate significance, such as Glia cell stimulating factor and polyclonal B-cell activator, are also described. This volume is organized into six sections encompassing 56 chapters and begins with an overview of assay systems, touching on topics such as the activation of macrophages by interferon to produce plasminogen and macrophage activation by lymphokine factors. The next sections turn to the production, purification, and biological and chemical characterization of lymphokines. The discussion then shifts to the mechanisms of action of lymphokines in vitro and the use of animal models in lymphokine investigations, including lymphokine fractions in a mouse tumor model and enhancement of natural killing activity by different types of interferon. A great deal of emphasis is placed on macrophage migration inhibitory factor, lymphotoxins, gamma interferon, and interleukins. The book concludes with chapters devoted to the immunoregulatory effects of lymphokines and clinical studies.

Book Description
Lymphokines: A Forum for Immunoregulatory Cell Products deals with immunoregulatory cell products that produce lymphokines. Topics covered include the purification and characterization of transfer factor; activation of cytotoxicity and/or suppressor activity in murine macrophages by lymphokines, lipopolysaccharide, and polyinosinic-polycytidylic acid; and the role of clotting processes in the action of lymphokines on macrophages. A comparison of the immune-modulating effects of interferon and interferon inducers is also presented. Comprised of 13 chapters, this volume begins with a discussion on transfer factor and its ability to react specifically with antigens. The clinical uses of transfer factor are considered with special emphasis on its value as a prophylactic agent. The reader is then introduced to the subject of T cell regulation of the immunoglobulin E (IgE) response via potentiating and suppressor lymphokines, together with the possible clinical application of IgE suppressive factors in the treatment of atopic diseases. Subsequent chapters examine the evidence in favor of the existence of T cell-derived polyclonal B cell activator (PBA) playing a role in both normal antibody responses and autoimmune diseases; the role of suppressor T cells and the associated lymphokines in contact sensitivity in mice; and lymphokine action on macrophages. The book also analyzes the genetics of the response of human and mouse cells to interferons. This monograph will be helpful to practitioners and researchers in the fields of microbiology and immunology.
