Pathogens exploit cellular functions to create an environment conducive to their persistence and propagation. Viruses and bacteria express effector-proteins or virulence factors, known to interfere at the molecular level with regulatory 'checkpoints' of numerous physiological events in the cell. A newly prominent area of research is the identification of pathogenic effector proteins that function on the host chromatin, their subversion/interference with chromatin regulatory processes, the short/long/heritable effects on the infected cell and the ultimate consequence of their expression at the organismal level.
