Most complex biological systems, such as enzyme pathways, are effec tively controlled near the beginning of the process. There is increasing evidence that the same is true for the immune system, with the initial interactions between antigen, antigen-presenting cells, and T cells hav ing a paramount influence on the ensuing events. Thus, analysis of the early stages of the immune responses has been a preoccupation of many immunologists. This has been considerably aided by the capac ity to expand these early events, and 'immortalize' them as clones of T cells, for detailed analysis. The discovery by Morgan, Ruscetti, and Gallo (Science 193, 1007, 1976) of T-cell growth factor (now termed interleukin-2 or IL-2) has had a major impact in immunology that is far from over. The greater ease of handling murine tissues experimentally, with the availability of more precisely defined reagents such as inbred strains, has meant that, to date, most of the work on long-term T-cell cultures has been per formed in the mouse, as summarized by Fathman and Fitch (eds. , Iso lation, Characterization and Utilization of T Lymphocyte Clones, Aca demic Press, NY, 1982). However, the limitations of working with human tissues are counterbalanced by the great long-term importance of understanding disorders of human immune regulation, especially since it is becoming evident that these are far from rare. Immune deficiencies such as agammaglobulinemia and T-cell deficiencies are not common, but immune hyperresponsiveness occurring in allergy and allergiC diseases (e. g.

Isolation, Characterization, and Utilization of T Lymphocyte Clones is a summary of information regarding T lymphocyte clones, including their usefulness. Organized into nine parts, the book begins with discussions on the soluble factors that can influence the growth of cloned T cells and the utilization of T cell hybridomas for analysis of T cell functions, emphasizing the biochemical and functional properties of helper and suppressor factors. The book then looks into the analysis of T cell clones and hybridomas using techniques of somatic cell genetics. The clonal analysis by limiting diluti ...

With a wide variety of investigative approaches, T cell immunology is a vital and open field of study. In T Cell Protocols, Second Edition, an international panel of experts contribute fully updated classic protocols as well as newly established novel techniques for the study of T lymphocyte biology. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters in this volume provide brief introductions to the topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and Notes sections which collect expert tips on troubleshooting and avoiding known pitfalls. Up-to-date and easy to use, T Cell Protocols, Second Edition is an ideal guide for young investigators new to the complex field of immunology as well as a valuable, concise resource for experienced scientists searching for clear, efficacious descriptions of novel methods.
