Stepwise specification of lymphocyte developmental lineages

Abstract

B and T lymphocytes differentiate from multipotent precursors through distinct specification and commitment steps. New findings on the unique role of Pax5 in B-lineage commitment, dichotomous action of Notch signaling in B versus T cell development, and the gene expression changes comprising T-lineage specification and commitment now illuminate this process.

Since the submission of this article, evidence has been published that Pax5 (BSAP) can interfere directly with transactivation functions of PU.1 [84]. This could play a role in repressing myelomonocytic genes during B-lineage commitment. The author is extremely grateful to David H Raulet (University of California, Berkeley), and to Hua Wang, Rochelle Diamond, Michele Anderson, F Chen, Gabriela Hernandez-Hoyos, and Janice Telfer in the author's laboratory for permission to cite results prior to publication. The manuscript was also greatly improved by the critical reading and advice of Eric Davidson, Janice Telfer, and Michele Anderson. Finally, the conceptual framework of this review was enriched by valuable discussions with Michael Levine, Eric Davidson, and members of the Developmental Biology Colloquium at Caltech.
