This study shows that the normal thymus produces immunoregulatory
CD25+4+8- thymocytes capable of
controlling self-reactive T cells. Transfer of thymocyte suspensions
depleted of CD25+4+8- thymocytes,
which constitute
5% of steroid-resistant mature
CD4+8- thymocytes in normal naive mice,
produces various autoimmune diseases in syngeneic athymic nude mice.
These CD25+4+8- thymocytes are
nonproliferative (anergic) to TCR stimulation in vitro, but potently
suppress the proliferation of other CD4+8- or
CD4-8+ thymocytes; breakage of their anergic
state in vitro by high doses of IL-2 or anti-CD28 Ab simultaneously
abrogates their suppressive activity; and transfer of such
suppression-abrogated thymocyte suspensions produces autoimmune disease
in nude mice. These immunoregulatory
CD25+4+8- thymocytes/T cells are
functionally distinct from activated CD25+4+ T
cells derived from CD25-4+ thymocytes/T cells
in that the latter scarcely exhibits suppressive activity in vitro,
although both CD25+4+ populations express a
similar profile of cell surface markers. Furthermore, the
CD25+4+8- thymocytes appear to
acquire their anergic and suppressive property through the thymic
selection process, since TCR transgenic mice develop similar
anergic/suppressive CD25+4+8-
thymocytes and CD25+4+ T cells that
predominantly express TCRs utilizing endogenous
-chains, but
RAG-2-deficient TCR transgenic mice do not. These results taken
together indicate that anergic/suppressive
CD25+4+8- thymocytes and
peripheral T cells in normal naive mice may constitute a common T cell
lineage functionally and developmentally distinct from other T cells,
and that production of this unique immunoregulatory T cell population
can be another key function of the thymus in maintaining immunologic
self-tolerance.
