The volume's broad synthesis of the current knowledge about immunity and tolerance includes molecular mechanisms of B and T lymphocyte development from the single cell to the entire organism and from single genes to genomes. There is a focus on the development and function of innate cells, including myeloid cells, natural killer cells, and a more recently defined innate lymphoid cell that resembles a T cell. Transcriptional regulation of key immune pathways in innate and adaptive cells of the immune system are covered. The effect of metabolic pathways on immune responses is discussed and, conversely, how immune cells may affect cell and tissue physiology outside of the immune response. Other topics include the protective effect of commensal bacteria, the diverse immune mechanisms underlying chronic infection or immune control in HIV and tuberculosis, and insights into autoimmune diseases that may lead to new clinical therapies.
