Focus on Epigenetic Control of Host Defence
Guest Editor: Mathias Merkenschlager

The cells of the immune system, and lymphocytes in particular, have a wide spectrum of programmatic choices when faced with stimuli such as invading pathogens. As a result lymphocytes are great model systems to study cell lineage choice and the regulation of gene expression. In addition to transcription factors, lineage choice and gene regulation are controlled by epigenetic mechanisms: modifications that do not alter the sequence of DNA, but rather change the chemical properties of DNA or the composition and post-translational modifications of proteins, RNA and other molecules that package DNA into chromatin. The power of epigenetic mechanisms is illustrated by the ability of pathogens to subvert host defences by undermining epigenetic mechanisms. In view of our growing understanding of epigenetic mechanisms, now is a good time to consider what epigenetics can teach us about the workings of the immune system. In this focus 8 illustrious researchers in immunology, haematology and epigenetics including Sudha Rao, Rafi Ahmed, George Lacaud, Pierre Ferrier and John O’Shea discuss our current understanding of epigenetic control of host defences.
