Environmental andLifestyle Factors That Shape thee Epigenome

Epigenetic marks are malleable andd respond to a wige range of exposaures. understanding how these factors influence autoimte risk is central to o both prevention and management. The interplay between genetics andd environment is often mediated by epigenetic changes.

Microbial and viral infections can alter host epigenetic landscapes. Epstein-Barr virus (EBV) encodes proteins such as LMP1 and EBNA2 that requilt host DNMTs andd HDAC, modifying methylation and histone marks to promote viral latency and distorst impete regulation. EBV infection is a strong risk factor for SLE and MS.
