lüll Epigenetic control in the immune response Reiner SLHum Mol Genet 2005[Apr]; 14 Spec No 1 (ä): R41-6Helper T cells engaged in an immune response confront a prevalent challenge for developmentally regulated gene expression: How does a cell give rise to daughter cells with different fates? Additionally, lymphocyte function is intimately associated with the processes of cell division and migration. This imposes an additional burden for daughter cells, to remember inductive events from which they are temporally and spatially removed. An emerging view is that helper T cells use epigenetic mechanisms tied to the structure of chromatin and its covalent modifications to achieve at least two important features of their programmed gene expression. Epigenetic effects organize the ability of signal transduction pathways to generate a restricted set of progeny from a multi-potent progenitor. In addition, epigenetic effects seem to allow dividing cells to memorize, or imprint, signaling events that occurred earlier in their development. Beyond helper T cells, the use of epigenetic effects is emerging as a common strategy in development and function of the mammalian immune system, suggesting that epigenetic effects may play a more prominent role in metazoan cell differentiation than previously appreciated. Lymphocytes are, thus, becoming a tractable system for genetic and biochemical dissection of the ways in which the genome is embedded with regulatory information to achieve developmental complexity.|*Epigenesis, Genetic[MESH]|*Gene Expression Regulation[MESH]|Animals[MESH]|Cell Communication[MESH]|Cell Differentiation[MESH]|Cell Lineage[MESH]|DNA Methylation[MESH]|Humans[MESH]|Immunity/*genetics[MESH]|Models, Biological[MESH]|Signal Transduction[MESH]|T-Lymphocytes/*immunology[MESH] |
