Project description:To determine the unique gene expression profile of central nervous system (CNS)-associated ILC3, we performed RNA-sequencing on sort-purified ILC3 from the CNS, cervical lymph nodes (cLN) and small intestine lamina propria (SI-LP) during EAE.

Project description:Autoimmune regulator (Aire) plays an indispensable role in the induction of central immune tolerance. We identify a novel subset of Rorγt-dependent innate lymphoid cell-type in secondary lymphoid organs, which presents endogenously generated antigens and contributes to peripheral T cell tolerance. In this experiment, transcriptomes of these Aire-ILC3 cells are characterized in wild-type Balb/C and Aire-/- Balb/C mice [Ramsey, C. et al. (2002) Hum Mol Genet 11:397-409] using RNA-seq method. To obtain the cells, peripheral lymph nodes were minced, enzymatically digested, and Aire-ILC3 cells were FACS-sorted as Lin-, MHCII+, CD80+, IL7Ra+ cells.

Project description:Type-3 innate lymphoid cells (ILC3) regulate homeostasis and orchestrate immunity in the intestine, mediated in part by their bi-directional communication with the intestinal epithelium. In order to define specific interactions between these two compartments, we used a reductionist co-culture system of murine epithelial small intestinal organoids (SIO) with ILC3. The transcriptomic profile of epithelial cells from these co-cultures was analysed by bulk RNAseq.

Project description:In the absence of NR4A2 in T cells mice do not develop early acute EAE, but only a late chronic disease. We examined the mechanism by which NR4A2 can control the pathogencity of T cells in CNS autoimmune disease. To determine how NR4A2 is involved is involved in T cell pathology, we examined expression profiles of T cells during early and late diease in the presence or genetic CD4-specific absence of NR4A2. T cells infiltrating CNS tissues were isolated at peal acute EAE (D18) or during late,chronic EAE (D32). RNA expression was then analysed by genechip to determine the influence of NR4A2 in T cells on these disease stages

Project description:ILC3 contain 3 well-defined subsets, CCR6+ ILC3, NKp46+ ILC3, and CCR6–NKp46– DN ILC3. These subsets had not previously been transcriptionally compared and the extent to which they had shared or unique transcriptional profiles remained unclear. We used microarray to determine transcriptional differences between these 3 subsets and to find putative factors that support the survival of CCR6+ ILC3 during cytokine depletion.

Project description:Iron metabolism is pivotal for cell fitness in the mammalian host. However, its role in group 3 innate lymphoid cells (ILC3s) is unknown. Here we show that transferrin receptor CD71-mediated iron metabolism cell-intrinsically controls ILC3 maintenance, cytokine production and host protection against Citrobacter rodentium infection, and metabolically affects mitochondrial respiration by switching of oxidative phosphorylation toward glycolysis. Iron deprivation or Tfrc deficiency reduces the expression and/or activity of the aryl hydrocarbon receptor (Ahr), a ligand-dependent transcription factor and a key ILC3 regulator. Furthermore, consistent with its role in generation of Ahr ligand, microbiome exerts a negative impact on CD71 expression in an Ahr-dependent manner. Genetic ablation or activation of Ahr in ILC3s leads to CD71 upregulation or downregulation, respectively, suggesting an active suppression of CD71 by Ahr. Iron overload partially restores defective ILC3 compartment in the small intestine of Ahr-deficient mice, representing compensatory action of CD71 upregulation during Ahr deficiency. Mechanistically, Ahr directly binds to the promoter region of the Tfrc locus to inhibit Tfrc transcription. These data collectively demonstrate an under-appreciated role of the Ahr-CD71-iron axis in regulation of ILC3 maintenance and function.

Project description:Group 3 innate lymphoid cells (ILC3) are innate immune effectors that contribute to host defense. Whether ILC3 functions are stably modified following pathogen encounter is unknown. Here we assess the impact of a time-restricted enterobacterial challenge to long-term ILC3 activation. We found that intestinal ILC3 persist for months in an activated state following exposure to Citrobacter rodentium. Upon rechallenge, these “trained” ILC3 proliferate, display enhanced interleukin (IL)-22 responses, and have a superior cell-intrinsic capacity to control infection compared to naïve ILC3. Metabolic changes occur in C. rodentium-exposed ILC3 but only trained ILC3 have enhanced proliferative capacity that contributes to elevated IL-22 production. Accordingly, a limited encounter with a pathogen can promote durable phenotypic and functional changes in intestinal ILC3 that contribute to long-term mucosal defense.
