Abstract
The maintenance of memory CD4 T cells is crucial for the establishment of immunological memory. The Polycomb (PcG) and Trithorax group (TrxG) genes control key developmental regulators such as the homeobox genes, and these two antagonize each other in the same developmental processes. Recently, PcG gene Bmi1 has been found to control memory Th1/Th2 cell survival and TrxG gene MLL is to control the maintenance of memory Th2 cell function selectively. Therefore, in memory CD4 T cells, PcG and TrxG genes appear to control distinct processes in a distinct manner, which indicates a novel regulatory feature of the PcG/TrxG genes.
