CD4/CD8 lineage commitment: matching fate with competence

Immunol Rev. 1998 Oct;165:195-207. doi: 10.1111/j.1600-065x.1998.tb01240.x.

Abstract

The outcome of positive selection of T lymphocytes is that there is a close match between the lineage adopted by a particular cell (CD4+ or CD8+) and the specificity of the T-cell receptor for the class of Major Histocompatibility Complex molecule recognized. How this match is obtained has been a matter of debate. We review the evidence, from recent and older experiments, that indicates that the process follows a selective logic, rather than an instructive one.
