title: Development and selection of T cells: how many subsets? How many rules?
abstract: Since the discovery indicating that thymus-derived lymphocytes (T cells) can be divided into two subpopulations: CD8+ (killer) and CD4+ (helper) cells, subsequent studies revealed a bewildering heterogeneity of T cells. In the present review an attempt is made to present the current picture of T cell heterogeneity, introduce some order into the nomenclature, and summarize the rules behind the development and selection of different currently recognized T cell subsets.
