Cell of Immunoglobulin Synthesis

Cells of Immunoglobulin Synthesis documents the proceedings of a symposium on ""Cells of Immunoglobulin Synthesis"" held at Arden House, on the Harriman Campus of Columbia University from June 9-11, 1978. The meeting was the third of the P & S Biomedical Sciences Symposia.
Starting with the opening address on B lymphocyte differentiation and the tolerance problem, 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 on immunoglobulin genes, messages, and molecules. Part II presents studies on cellular immunoglobulin production. Part III examines membrane immunoglobulins while Part IV focuses on immunoglobulins as regulatory molecules. Part V deals with lymphocyte hybrids. Part VI examines immunoglobulin idiotypes while Part VII contains papers on the ontogeny of immunoglobulin-synthesizing cells.
