"Lymphocyte Development" presents an extremely up-to-date account of molecular processes involved in the development of lymphocytes. This well written book is based on a graduate course taught by the author. Topics include the selection processes involved in lymphocyte maturation, immune receptor gene rearrangement, signaling pathways involved in cell cycle progression and apoptosis, and the transcriptional regulation of lymphoid ontogeny. The book also covers T cell development and differentiation of helper and cytotoxic T cells as well as the development of Natural Killer lymphocytes. The book finishes with an account of the molecular basis of immunodeficiency syndromes. It will interest researchers in immunology and it will be useful as a supplementary text for a graduate level immunology course.
