Epigenetics in immune development and in allergic and autoimmune diseases

Abstract

Epigenetic mechanisms such as DNA methylation, histone modification, and micro RNA signaling regulate the activity of the genome. Virtually all aspects of immunity involve some level of epigenetic regulation, whether it be host defense or in mediating tolerance. These processes are critically important in mediating dynamic responses to the environment over the life course of the individual, yet we are only just beginning to understand how dysregulation in these pathways may play a role in immune disease. Here, we give a brief chronological overview of epigenetic processes during immune development in health and disease.

Keywords: DNA methylation; Epigenetics; Immune development; Immune disease; Immune function.
