IL-27-Induced Type 1 Regulatory T-Cells Produce Oxysterols that Constrain IL-10 Production
The behaviors of lymphocytes, including CD4+ T helper cells, are controlled on many levels by internal metabolic properties. Lipid metabolites have recently been ascribed a novel function as immune response modulators and perturbation of steroids pathways modulates inflammation and potentially promotes a variety of diseases. However, the impact of lipid metabolism on autoimmune disease developm...
متن کاملResident CD141 (BDCA3)+ dendritic cells in human skin produce IL-10 and induce regulatory T cells that suppress skin inflammation
Human skin immune homeostasis, and its regulation by specialized subsets of tissue-residing immune sentinels, is poorly understood. In this study, we identify an immunoregulatory tissue-resident dendritic cell (DC) in the dermis of human skin that is characterized by surface expression of CD141, CD14, and constitutive IL-10 secretion (CD141(+) DDCs). CD141(+) DDCs possess lymph node migratory c...
متن کاملOX40 ligand shuts down IL-10-producing regulatory T cells.
IL-10-producing CD4(+) type 1 regulatory T (Tr1) cells play a critical role in the maintenance of peripheral tolerance. Although immunosuppressive drugs, cytokines, costimulatory molecules, and immature dendritic cells are implicated in the induction of Tr1 cells, the signals that negatively regulate the generation and function of Tr1 cells have been elusive. We report that OX40 ligand (OX40L) ...
متن کاملGATA-3 directly remodels the IL-10 locus independently of IL-4 in CD4+ T cells.
IL-10 is a major regulator in inflammatory responses. Although various transcription factors were defined to enhance IL-10, the molecular mechanism for the initiation of Il-10 transcription, remains unknown. mRNA profiling of six distinct primary CD4+ T cell populations showed differential expression of the transcription factor GATA-3 correlated with levels of IL-10 expression. We showed that e...
متن کاملIL-27 regulates IL-10 and IL-17 from CD4+ cells in nonhealing Leishmania major infection.
Control of infection caused by Leishmania major requires the development of IFN-gamma+CD4+ lymphocytes for the induction of microbicidal activity in host macrophages. We recently reported on the inability of conventionally resistant C57BL/6 mice to successfully resolve infection by an isolate of L. major, despite a strong IFN-gamma response by the host. Susceptibility was caused by Ag-specific ...
