Once inhaled, our first line of defense against SARS-CoV-2 is the innate immune response—a system that is intimately linked to epigenetics.
Though there is much to learn about this virus and this disease, we know many ways that epigenetics is involved in infection and immunity.
The severity of disease and the inability to fight it off can, in part, be attributed to epigenetic dysregulation of an aging immune system.
