Dynamic expression of Id3 defines the stepwise differentiation of tissue-resident regulatory T cells

Project description:Foxp3+ regulatory T (TR) cells are phenotypically and functionally diverse, and broadly distributed in lymphoid and non-lymphoid tissues. However, the pathways guiding the differentiation of tissue-resident TR populations have not been well defined. By regulating E-protein function, Id3 controls the differentiation of CD8+ effector T cells and is essential for TR maintenance and function. We show that dynamic expression of Id3 helps define three distinct mouse TR populations, Id3+CD62LhiCD44lo central (c)TR, Id3+CD62LloCD44hi effector (e)TR and Id3- eTR. Adoptive transfer experiments and transcriptome analyses support a stepwise model of differentiation from Id3+ cTR to Id3+ eTR to Id3- eTR. Furthermore, Id3- eTR have high expression of functional inhibitory markers and a transcriptional signature of tissue-resident TR. Accordingly, Id3- eTR are highly enriched in non-lymphoid organs, but virtually absent from blood and lymph. Thus, we propose that tissue-resident TR develop in a multi-step process associated with Id3 downregulation.

Differentiation and specification of resident tissue macrophages [ID3-KO RNA-seq]

Project description:Tissue resident macrophages are functionally diverse cells that share an embryonic mesodermal origin. However, the mechanism(s) that control their specification remain unclear. We performed transcriptional, molecular and in situ spatio-temporal analyses of macrophage development in mice. We report that Erythro-Myeloid Progenitors generate pre-macrophages (pMacs) that simultaneously colonize the head and caudal embryo from embryonic day (E)9.5 in a chemokine-receptor dependent manner, to further differentiate into tissue F4/80+ macrophages. The core macrophage transcriptional program initiated in pMacs, is rapidly diversified in early macrophages as expression of transcriptional regulators becomes tissue-specific. For example, the preferential expression of the transcriptional regulator Id3 initiated in early fetal liver macrophages appears critical for Kupffer cell differentiation, as inactivation of Id3 causes a selective Kupffer cell deficiency that persists in adults. We propose that colonization of developing tissues by differentiating macrophages is immediately followed by their specification as they establish residence, hereby generating the macrophage diversity observed in post-natal tissues.

Id3 Orchestrates Germinal Center B Cell Development

Project description:Previous studies have demonstrated that E-proteins induce AID expression in activated B cells. Here we have examined the role of Id3 in germinal center (GC) cells. We found that Id3 expression is high in follicular B-lineage cells but declines in GC cells. Immunized mice depleted for Id3 expression displayed a block in germinal center B cell maturation, showed reduced numbers of marginal zone B cells and class switched cells, were associated with decreased antibody titers and lower numbers of plasma cells. In vitro Id3-depleted B cells displayed a defect in class switch recombination. Whereas AID levels were not altered in Id3-depleted activated B cells, the expression of a subset of genes encoding for signaling components of antigen receptor, cytokine receptor and chemokine receptor mediated signaling was significantly impaired. We propose that during the GC reaction Id3 levels decline to activate the expression of genes encoding for signaling components that mediate B cell receptor and or cytokine-mediated signaling to promote the differentiation of GC B cells.

Expression data from sorted Id3-GFP hi Id2-YFP int and Id3-GFP lo Id2-YFP hi activated CD8 T cells

Project description:During an immune response, CD8 T cells fall along a gradient of memory potential, but the regulators of these fate decsisions are not well understood. We utlized Id3-GFP and Id2-YFP reporter mice to elucidate the role of Id3 and Id2 during early CD8 T cell differentiation by gene expression. Id3-GFP hi Id2-YFP int or Id3-GFP lo Id2-YFP hi OT-I cells were sorted into trizol at day 6 of VSV-OVA infection and analyzed by microarray

Gene expression profiles after induced Id3 levels in A431 squamous carcinoma cells

Project description:Previously it has been shown that Id3 can act as an apoptosis-inducer gene in immortalized human keratinocytes. To further investigate the role of Id3 in the progression of skin cancer, the role of Id3 in A431 cells is investigated through ectopic induction of Id3. Microarray analysis is used to guide us the genes and pathways that are significantly altered after Id3 induction.
