Regulatory T Lymphocytes

Regulatory T Lymphocytes documents the proceedings of a symposium on ""Regulatory T Lymphocytes"" held at Arden House on the Harriman Campus of Columbia University from June 8-10, 1979. The meeting was the fourth of the P&S Biomedical Sciences Symposia. Starting with the opening address on regulatory T lymphocytes and their antigen receptors, the remainder of the book presents the contributions made by researchers at the symposium. These contributions are organized into seven parts. Part I contains studies T cell receptors. Part II presents studies on T cell subpopulations. Parts III and IV examine helper T cells. Parts V and VI deal with suppressor T cells. Part VII contains papers on regulatory T cell circuits.
