A growing number of diseases in humans, including trauma, certain cancers, and
infection, are known to be associated with l-arginine deficiency. In addition,
l-arginine must be supplemented by diet during pregnancy to aid fetal
development. In conditions of l-arginine depletion, T cell proliferation is
impaired. We have previously shown that neonatal blood has lower l-arginine
levels than adult blood, which is associated with poor neonatal lymphocyte
proliferation, and that l-arginine enhances neonatal lymphocyte proliferation
through an interleukin (IL)-2-independent pathway. In this study, we have further
investigated how exogenous l-arginine enhances neonatal regulatory T-cells
(Tregs) function in relation to IL-10 production under epigenetic regulation.
Results showed that cord blood mononuclear cells (CBMCs) produced higher levels
of IL-10 than adult peripheral blood mononuclear cells (PBMCs) by
phytohemagglutinin stimulation but not by anti-CD3/anti-CD28 stimulation.
Addition of exogenous l-arginine had no effect on transforming growth factor-?
production by PBMCs or CBMCs, but enhanced IL-10 production by neonatal
CD4(+)CD25(+)FoxP3(+) Tregs. Further studies showed that IL-10 promoter DNA
hypomethylation, rather than histone modification, corresponded to the
l-arginine-induced increase in IL-10 production by neonatal CD4(+) T cells. These
results suggest that l-arginine modulates neonatal Tregs through the regulation
of IL-10 promoter DNA methylation. l-arginine supplementation may correct the
Treg function in newborns with l-arginine deficiency.
