Ontogeny of CD4+CD25+ regulatory/suppressor T cells in human fetuses.

Abstract excerpt

Little is known about the ontogeny of naturally occurring CD4(+)CD25(+) regulatory/suppressor T cells that play a major role in maintaining self-tolerance in mice and humans. In rodents, thymectomy on day 3 of life leads to multiple organ-specific autoimmune diseases that can be prevented by adoptive transfer of regulatory T cells, suggesting their neonatal development. We investigated regulatory T-cell ontogeny...
