Abstract: The ability to produce vigorous immune responses that spare self tissues and organs depends on the elimination of autoreactive T and B cells. However, purging of immature and mature self-reactive T and B cells is incomplete and may also require the involvement of cells programmed to suppress immune responses(1). Regulatory T cells (T-reg) belonging to the CD4(+) T-cell subset may have a role in preventing untoward inflammatory responses, but T-cell subsets programmed to inhibit the development of autoantibody formation and systemic-lupus-erythematosus-like disease have not yet been defined(2). Here we delineate a CD8(+) regulatory T-cell lineage that is essential for the maintenance of self tolerance and prevention of murine autoimmune disease. Genetic disruption of the inhibitory interaction between these CD8(+) T cells and their target Qa-1(+) follicular T-helper cells results in the development of a lethal systemic-lupus-erythematosus-like autoimmune disease. These findings define a sublineage of CD8 T cells programmed to suppress rather than activate immunity that represents an essential regulatory element of the immune response and a guarantor of self tolerance.
