Epigenetics, aging, and autoimmunity.
Immune senescence is associated with a decline in T- and B-cell immune responses. It is, therefore, perhaps surprising that aging is linked to the appearance of serological and clinical autoimmunity. Here we review the mechanisms that contribute to the increase in inflammatory and autoimmune responses in aging. The bulk of this review will focus on aging-associated changes in epigenetic mechanisms, and in particular DNA methylation, as this has emerged as an attractive mechanistic link between aging and autoimmunity.
