Abstract:
:The suppressive effects of CD4+CD25+ regulatory T cells (Tregs) on T cells have been well documented. Here we investigated whether human CD4+CD25+ Tregs can inhibit the proinflammatory properties of monocytes/macrophages. Monocytes and T cells were isolated from peripheral blood of healthy volunteers by magnetic cell separation and cocultured for 40 h. Monocytes were analyzed directly for cytokine production and phenotypic changes or repurified and used in T-cell stimulation and lipopolysaccharide challenge assays. Coculture with CD4+CD25+ Tregs induced minimal cytokine production in monocytes, whereas coculture with CD4+CD25- T cells resulted in large amounts of proinflammatory (tumor necrosis factor-alpha, interferon-gamma, interleukin-6) and regulatory (interleukin-10) cytokines. Importantly, when these CD4+CD25+ Treg-treated monocytes were repurified after coculture and challenged with lipopolysaccharide, they were severely inhibited in their capacity to produce tumor necrosis factor-alpha and interleukin-6 compared with control-treated monocytes. In addition, monocytes that were precultured with CD4+CD25+ Tregs displayed limited upregulation of human leukocyte antigen class II, CD40 and CD80, and downregulation of CD86 compared with control-treated monocytes. This altered phenotype had functional consequences, as shown by the reduction in T cell-stimulatory capacity of Treg-treated monocytes. Together, these data demonstrate that CD4+CD25+ Tregs can exert direct suppressive effects on monocytes/macrophages, thereby affecting subsequent innate and adaptive immune responses.
