β¦ Synopsis
Thymocytes co-expressing the CD4 and CD8 co-receptors differentiate into mature T cells that express either CD4 or CD8 and have helper or cytotoxic functions, respectively. Recent studies indicate that commitment to the CD4+ or CD8+ lineages occurs stochastically, but retention of the appropriate co-receptor is required to complete development.
