Gene expression profile of ILC2 from naïve wild type mice

Project description:Under unstimulated conditions, there is a low abundance of lung ILC2 cells, which adds to the complexity of analyzing the RNA transcriptome. We examined the expression profile of ILC2 cells of untreated naïve mice.

Expression profile of bcl11b-deficient NAÏVE CD8+ T cells versus wild type

Project description:Naïve CD44low CD25low CD8+ T cells from Bcl11bF/F/dLck-iCre and wild type mice at steady state were sorted at 90% purity, RNA was extracted and profile for mRNA expression to identify mRNAs differentially expressed in Bcl11b-/- naïve CD8+ T cells versus wild type. Naïve CD44low CD25low CD8+ T cells purified from Bcl11bF/F/dLck-iCre and wild type mice and investigated for mRNA expression

Expression data of ILC2 cells from Ets1-deleted and littermate control mice

Project description:The ETS1 transcription factor is required for the development and cytokine-induced expansion of ILC2 ILC2 cells isolated from ETS1-deleted or litter mate control mice were cultured on OP9-DL1 with IL-7 and IL-33. Subsequently, RNA from ICOS+ cells was extracted, labelled and hybridized to Affymetrix microarrays. The goal of this study is to investigate ETS1-dependent genes in developing ILC2 cells.

Amino acid availability acts as a metabolic rheostat to determine the magnitude of ILC2 responses - WT ILC2

Project description:Group 2 innate lymphoid cells (ILC2) are functionally poised, tissue-resident lymphocytes that respond rapidly to damage and infection at mucosal barrier sites. ILC2 reside within complex microenvironments where they are subject to cues from both the diet and invading pathogens – including helminths. Emerging evidence suggests ILC2 are acutely sensitive not only to canonical activating signals, but also perturbations in nutrient availability. In the context of helminth infection, we identify amino acid availability as a nutritional cue in regulating ILC2 responses. ILC2 were found to be uniquely pre-primed to import amino acids via the large neutral amino acid transporters Slc7a5 and Slc7a8. Cell-intrinsic deletion of these transporters individually impaired ILC2 expansion, while concurrent loss of both transporters markedly impaired the proliferative and cytokine producing capacity of ILC2. Moreover, amino acid determined the magnitude of ILC2 responses in part via tuning of mTOR. These findings implicate essential amino acids as a metabolic requisite for optimal ILC2 responses within mucosal barrier tissues.

Dichotomous metabolic networks govern human ILC2 proliferation and function

Project description:Group 2 innate lymphoid cells (ILC2) represent innate homologues of Th2 cells that participate in immune defense and tissue homeostasis through production of type 2 cytokines. While T lymphocytes metabolically adapt to microenvironmental changes, knowledge of human ILC2 metabolism is limited and its key regulators are unknown. Here we show that circulating “naïve” ILC2 have an unexpected metabolic profile with a higher level of oxidative phosphorylation (OXPHOS) than NK cells. Accordingly, ILC2 are severely reduced in patients with mitochondrial disease and impaired OXPHOS. Metabolomic and nutrient receptors analysis reveals ILC2 uptake amino acids to sustain OXPHOS at steady-state. Upon activation with interleukin 33 (IL-33), ILC2 become highly proliferative relying on glycolysis and mTOR to produce IL-13, while continuing to fuel OXPHOS with amino acids to maintain cellular fitness and proliferation. Our results suggest that proliferation and function are metabolically uncoupled in human ILC2, offering new strategies to target ILC2 in disease settings.

Human ILC2 cells stimulated with IL-25, IL-33, or TSLP

Project description:ILC2 cells are a newly described cell type whose biology and contribution to disease are poorly understood. ILC2 cells are activated by allergens, viral infection, and/or epithelial damage via IL-33 and IL-25. ILC2 cells require IL-2, IL-7, IL-25 and IL-33 for their survival and expansion. In mice, ILC2s produce multiple mediators primarily associated with type 2 inflammation (IL-13, IL-5, IL-4, IL-6, IL-9, IL-10, GM-CSF, amphiregulin). ILC2 cells may contribute to the pathology of asthma through multiple mediators that include IL-13-independent pathways. Our goal is to compare transcriptional profiles of IL-33- or IL-25-activated ILC2 cells from blood to characterize these cells and to identify marker(s) that can be utilized to detect them in human tissue. ILC2 cells (Lineage negative, CRTH2+, CD161+, CD127+) were purified from human blood of 5 different donors by flow cytometry. The ILC2 yield ranged from 20,000 to 165,000 cells per donor (0.001-0.008% WBC). Purified ILC2s were expanded in vitro in the presence of IL-2, IL-7, IL-33 and IL-25 (each at 50 ng/ml) for 7-10 days. Expanded cells maintained the ILC2 phenotype (Lineage negative, CRTH2+, CD161+, CD127+). The cells were rested for 2 days in the presence of 1 ng/ml IL-2 and IL-7 and then treated in the presence of 1 ng/ml IL-2 and IL-7 with either media control, IL-25 (50 ng/ml), IL-33 (50 ng/ml), and/or TSLP (50 ng/ml) in combination, for 6 or 24 hours. Whole RNA was isolated via the RNeasy kit (Qiagen). Stratagene Universal Human Reference RNA was used as the reference.
