最近的研究表明,调节性CD 4 + CD 25 + CD 45 RO + T细胞存在于健康成人的外周血中,并发挥与啮齿动物类似的调节功能。仍然很难理解这些T细胞中的一小部分是如何通过直接的细胞与细胞接触而不是通过分泌免疫抑制细胞因子来调节的,它们如何介导强烈的免疫抑制。在这里,我们表明,人CD 4 + CD 25 + T细胞诱导长期无反应性和产生白细胞介素(IL)-10在CD 4 + CD 25 − T细胞。这些失能的CD 4 + CD 25 − T细胞然后通过IL-10抑制同基因CD 4 + T细胞的增殖,但不依赖于直接细胞接触,类似于所谓的1型调节性T(Tr 1)细胞。CD 4 + CD 25 + T细胞诱导Tr 1样细胞的这种“催化”功能有助于解释它们在维持免疫稳态中的核心作用。
It has been recently demonstrated that regulatory CD4+CD25+ CD45RO+ T cells are present in the peripheral blood of healthy adults and exert regulatory function similar to their rodent counterparts. It remains difficult to understand how the small fraction of these T cells that regulate via direct cell-to-cell contact and not via secretion of immunosuppressive cytokines could mediate strong immune suppression. Here we show that human CD4+CD25+ T cells induce long-lasting anergy and production of interleukin (IL)-10 in CD4+CD25− T cells. These anergized CD4+CD25− T cells then suppress proliferation of syngenic CD4+ T cells via IL-10 but independent of direct cell contact, similar to the so-called type 1 regulatory T (Tr1) cells. This ‘catalytic’ function of CD4+CD25+ T cells to induce Tr1-like cells helps to explain their central role for the maintenance of immune homeostasis.
