“…However, Th2 cells can be stimulated to express FOXP3 [80] and the expression of FOXP3 by Th2 cells is associated diminished pathogenic activity [80]. In addition, IL-4 can promote FOXP3 expression in naïve CD4 + cells suggesting a possible interplay between Th2 cells and regulatory cells [81]. If we assume that the current literature describes all regulatory cell subsets we might conclude that the tolerant CD4 + KJ1-26 + regulatory cell population contains a mixture of cell subsets including Tr1 cells, Tregs, and Th2 cells that do or do not express FOXP3.…”

Treatment with a cocktail of CD4 and CD8-specific monoclonal antibodies (mAb) induces long-term transplantation tolerance and regulatory CD4 + T cells that induce tolerance in non-tolerant T cells. In contrast, treatment with a CD4-specific mAb alone fails to induce long-term tolerance. The current study was designed to test the hypothesis that CD8 blockade plays a role in promoting the development of CD4 + regulatory T cells.Using the DO11.10 CD4 + TCR transgenic mouse model we show that treatment with a CD4/CD8-specific mAb cocktail induces antigen-specific tolerance to OVA, measured by a significant decrease in OVA-specific IgG, on challenge with antigen. Although treatment with OVA and the CD4-specific mAb alone also induces a significant decrease in OVA-specific antibody, the number of DO11.10 cells is significantly greater in mice treated with the CD4/CD8-specific mAb cocktail, and this is associated with a significant increase in proliferation of DO11.10 cells in response to specific antigen. DO11.10 cells sorted from mice made tolerant to OVA with the CD4/CD8-specific mAb cocktail promote an OVA-specific IgG1 (Th2-type) response but not an OVA-specific IgG3 (Th1-type) response on transfer into new syngeneic recipients, suggesting their ability to regulate the type of antigen-specific immune response that ensues after priming with antigen. In addition, DO11.10 cells from tolerant mice express markers that are characteristic of CD4 + regulatory cells, including FOXP3, GITR and CTLA4, but not CD25. Taken as a whole, these data suggest that CD8 blockade promotes CD4 + FOXP3 + regulatory CD4 + T cells by promoting their proliferation in tolerant mice.

“…Both can inhibit proliferation of T cells and are also important in the differentiation of T cells into Treg. Recently, IL-4 and IL-13 have also been shown to induce Foxp3 1 T cells from CD4 1 CD25 À T cells [28]. We reasoned that resting B cells must express a cytokine that is not expressed by activated B cells, preferentially enabling resting B cells to increase Treg numbers.…”

Regulatory T cells (Treg) play critical roles in maintaining tolerance and preventing autoimmunity. It is not fully clear how these cells are generated and maintained. Here, we show that resting B cells are able to expand Treg. This expansion requires TGF-b3 and signaling through the TCR and CD28. Upon activation, B cells express less TGF-b3, which reduces their capacity to expand Treg and which also results in increased Treg death. This may ensure that B cells can function as potent professional antigen presenting cells during infections. However, in the absence of any infection, we find that B-cell-deficient lMT mice have decreased percentages of Treg in the periphery. Our data suggest that resting B cells, which may be presenting self-antigens to T cells, can expand and maintain specific Treg and thus might be involved in the prevention of autoimmunity. Key words: B cells . Regulatory T cells . Tolerance Supporting Information available online IntroductionRegulatory T cells (Treg) are a subset of T cells that can actively suppress innate as well as adaptive immunity and have been implicated in self-tolerance, autoimmunity, cancer, transplantation immunology and a myriad of infectious diseases [1][2][3][4][5][6]. There are numerous different subsets of Treg based on their phenotypic markers, amonge which the naturally occurring Treg (nTreg) population is well studied and characterized. nTreg are a subset of CD4 1 T cells expressing CD25 and the transcription factor Forkhead box protein 3 (Foxp3). Foxp3 has been shown to be the master regulator for the generation of nTreg. Although Foxp3 À/À mice lack CD4 1 CD25 1 T cells, expression of Foxp3 in CD4 1 CD25 -T cells is sufficient for converting them into CD4 1 CD25 1 T cells with suppressive function [7,8].CD4 1 CD25 1 Foxp3 1 Treg arise in the thymus and enter into the periphery where they constitute $5-10% of the CD4 1 T cells. nTreg generation in the thymus is thought to require high-affinity peptide-MHC class II interactions in contrast to low-affinity peptide-MHC class II interactions required for positive selection of conventional CD4 1 T cells [9,10]. There are also strong evidences for the generation of CD4 1 CD25 1 Foxp3 1 Treg in the periphery. Experiments carried out in thymectomized or RAG-2-deficient mice lacking CD4 1 CD25 1 T cells show that nTreg can be generated in the periphery from CD4 1 CD25 À T cells [11,12].In addition to co-stimulation via the B7-CD28 and TCR-MHC class II pathways, various cytokines such as IL-2, TGF-b1 and IL-10 have been associated with the generation of peripheral Treg. IL-2 and IL-2R knockout mice have few, if any, nTreg and develop severe lymphoproliferation and autoimmunity [13,14]. TGF-b1 or IL-10 have been shown to expand Treg and even convert CD4 1 CD25 À T cells into CD4 1 CD25 1 T cells with suppressive functions [13,[15][16][17][18].Antigen presenting cells (APC) express both MHC class II as well as B7 molecules and secrete cytokines that may modulate the differentiation of T cells into either T-effector or T-r...

A deficit in IL-4 production has been previously reported in both diabetic human patients and nonobese diabetic (NOD) mice. In addition, re-introducing IL-4 into NOD mice systemically, or as a transgene, led to a beneficial outcome in most studies. Here, we show that prediabetic, 12-wk old female NOD mice have a deficit in IL-4 expression in the pancreatic lymph nodes (PLN) compared to age-matched diabetes-resistant NOD.B10 mice. By bioluminescence imaging, we demonstrated that the PLN was preferentially targeted by bone marrow-derived dendritic cells (DCs) following intravenous (IV) administration. Following IV injection of DCs transduced to express IL-4 (DC/ IL-4) into 12-wk old NOD mice, it was possible to significantly delay or prevent the onset of hyperglycemia. We then focused on the PLN to monitor, by microarray analysis, changes in gene expression induced by DC/IL-4 and observed a rapid normalization of the expression of many genes, that were otherwise under-expressed compared to NOD.B10 PLN. The protective effect of DC/IL-4 required both MHC and IL-4 expression by the DCs. Thus, adoptive cellular therapy, using DCs modified to express IL-4, offers an effective, tissue-targeted cellular therapy to prevent diabetes in NOD mice at an advanced stage of pre-diabetes, and may offer a safe approach to consider for treatment of high risk human pre-diabetic patients.
