Ontogeny of T-cell precursors: a model for the initial stages of human T-cell development. 1989

B F Haynes, and S M Denning, and K H Singer, and J Kurtzberg

Although most investigators agree that the CD4- CD8- CD3- thymocyte subset represents the most immature intrathymic T cell capable of repopulating the thymus in vivo, little is known of the earliest stages of human T-cell development. Using mAbs to hematopoietic and T-cell lineage molecules in quantitative immunofluorescence studies, new insight has been gained regarding the phenotype of human T-cell precursors before and after colonization of human thymic rudiment. In this article, Barton Haynes and colleagues discuss the sequential expression of CD7, CD4, CD8, CD3, CD2, CD1, CD45, TCR gamma delta and TCR alpha beta, and propose a model defining the stages of T-cell precursors during fetal ontogeny.

D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D019011 Antigens, CD7 Differentiation antigens expressed on pluripotential hematopoietic cells, most human thymocytes, and a major subset of peripheral blood T-lymphocytes. They have been implicated in integrin-mediated cellular adhesion and as signalling receptors on T-cells. CD7 Antigens,CD7 Antigen,Antigen, CD7
