Synopsis

It has been 12 years since the first proposal was made to sub- divide mouse CD4 I T cell clones into Th I and Th2 subsets, based on their differences in cytokine production, and 7 years since the first clear demonstration of a similar dichotomy among human T cell clones. In the ensuing period, it has been realized that inappropriate development of Th I or Th2 responses are important features of many immunological and infectious dis- eases. Perhaps the first group of diseases to be understood in terms of preferential Th subset activation were allergic diseases (see PARRONC'HI et aI. , this volume). Several of the major, co- ordinately regulated, features of allergy, including IgE, eosino- philia and mastocytosis, were found to be stimulated by the T- specific cytokines I L-4 and IL-5 and inhibited by the Th I cyto- kine, IFN-. This suggested that the presence and severity of al- lergic responses reflected the relative numbers of Th I and Th2 cells specific for the offending allergen. Similarly, the very dif- ferent consequences of protective Th I and nonprotective Th2 responses to a number of intracellular pathogens have been re- cognized for some time (see TRINCHIERI and SCOTI, and COFF- MAN et aI. , this volume).

Product Description

The two major subsets of CD4+ helper T cells, designated Th1 and Th2, have quite different patterns of cytokine production and, as a consequence, have very different roles in immune responses. The articles in this volume review both basic and clinical studies of T cell heterogeneity, including: - The mechanisms by which Th1 and Th2 cells develop and maintain their differences in cytokine production - The different roles of Th1 and Th2 cells in allergy, autoimmunity and infectious diseases - The prospects and strategies for therapeutic manipulation of Th1 and Th2 cells - The control of Th1 and Th2 responses by regulatory T cell subsets. The volume will give the reader a current view of the development and function of Th1 and Th2 cells and the attempts to treat immunological diseases with therapies directed towards altering the Th1/Th2 balance.
