The thymus is an evolutionarily ancient primary lymphoid organ common to
all vertebrates in which T cell development takes place. Failing thymus
function is associated with immunodeficiency and/or autoimmunity. In
this volume, leading experts provide a comprehensive overview of recent
advances in thymopoiesis research. The chapters cover the development of
the thymic epithelial microenvironment, address the formation of a
diverse and self-tolerant repertoire of T cell receptors as the basis
for cellular immunity, discuss the mechanisms by which progenitor cells
colonize the thymus and detail the molecular basis for T lineage
decisions. The reviews illustrate the important role of the multifaceted
process of thymopoiesis for adaptive immunity.
