, T-cell receptors, CTLA4, and CD4 ) or from loci of associated diseases (i.e.
Recently, a subset of CD4 +T cells was identified that is present on 5-10% of CD4 +T cells in normal naïve mice and expresses CD25 (the α-chain of IL-2 receptor) [ 4 5 ] . Functional analysis of murine CD4 +CD25 +T cells showed that those cells, which constitutively express cytotoxic T-lymphocyte antigen (CTLA)-4 [ 6 7 8 ] , fail to proliferate or secret cytokines in response to polyclonal or antigen-specific stimulation, but inhibit the activation of conventional responsive T cells [ 1 2 3 8 9 ] . The suppressive activity of the CD4 +CD25 +T cells depends on signaling via the negative regulator of T-cell activation CTLA-4 [ 7 ] and requires a cell-cell interaction that possibly involves cell surface bound transforming growth factor (TGF)-β 1 [ 1 10 ] . It has been shown that B7/CD28 costimulation is essential for the development and homeostasis of the CD4 +CD25 +regulatory T cells [ 6 ] , which play critical roles not only in preventing autoimmunity but also in controlling tumor immunity and transplantation tolerance [ 2 11 ] .
AICD = activation-induced cell death; CTLA = cytotoxic T-lymphocyte antigen; ELISA = enzyme-linked immunosorbent assay; FITC = fluorescein isothiocyanate; IL = interleukin; PE = R-phycoerythrin; PG = proteoglycan; PGIA, proteoglycan-induced arthritis; SCID = severe combined immunodeficient; TCR = T-cell receptor; TGF = transforming growth factor; WT = wild-type.
We were unable to detect linkage at IDDM3 and at CTLA4, for which positive linkages were previously reported.
