Activation-induced cell death of ILC2s via TIGIT suppresses chronic airway allergy

Project description:Chronic allergy induces TIGIT+ ILC2s at the sites of severe inflammation. To clearly isolate and follow the TIGIT+ ILC2s, we generated Tigit-Cre-ERT2: Rosa26-loxp-stop-loxp-tdTomato mice. tdTomato expression was induced in the TIGIT+ ILC2 of the mice by repeated intranasal administration of papain and oral tamoxifen treatment for 19 days. The tdTomato- and + ILC2s were sorted for RNA-seq and ATAC-seq analysis. We then performed gene expression profiling analysis using data obtained from RNA-seq of tdTomaoto- and + ILC2s. To call peaks, ATAC-seq data were aggregated by each unique cell type, and peak summits were called using HOMER.

Expression data from naive, effector and memory-like ILC2s isolated from mouse lungs and those from effector and memory-like ILC2s isolated from mediastinal lymph node

Project description:Group 2 innate lymphoid cells (ILC2s) in the lung are stimulated by inhaled allergens. ILC2s do not directly recognize allergens but they are stimulated by cytokines including interleukin (IL)-33 released by damaged epithelium.Lung ILC2s, upon stimulation, produce T helper 2 cell-type cytokines inducing T cell independent allergic lung inflammation. We now report that lung ILC2s, upon activation by an allergen or IL-33, acquire the properties of memory cells. The activated ILC2s initially proliferate and secrete cytokines, followed by a contraction phase as they stop producing cytokines. Nevertheless, some persist long after the resolution of the inflammation and acquire intrinsic capacities to react to unrelated allergens more vigorously than naÃ¯ve ILC2s, thus mediating a severe allergic lung inflammation. Gene expression profiles of the previously activated ILC2s show a gene signature of memory T cells. These antigen non-specific memory ILC2s may explain why asthma patients are often sensitized to multiple allergens. ILC2s were isolated from mouse lungs from naive and IL-33 injected mice 4 days, 14 days and 4 months after the initial treatment. RNA was extracted from those ILC2 populations and analyzed for gene expression profiles. RNA was also extracted from ILC2s isolated from lung draining mediastinal lymph node (mLN) 4 days and 14 days after IL-33 treatment.

Single nuclei RNA sequencing of skin draining lymph nodes in the setting of skin inflammation and RAG1 fate mapping

Project description:Type 2 inflammation contributes to the pathology of skin diseases such as atopic dermatitis (AD) and urticaria. We previously found that AD-like inflammation induced by calcipotriol in mice is critically mediated by group 2 innate lymphoid cells (ILC2s), while T cells and B cells are dispensable given development of robust AD-like disease in RAG knockout mice. Indeed, we found that in RAG knockout mice AD-like inflammation was worse, with a proportion of ILC2s displaying increased markers of activation. The goal of this study was to characterize transcriptional and epigenomic changes in ILC populations with a history, or not, of expressing RAG1 in the setting of AD-like skin inflammation.

Proteome of group 2 innate lymphoid cells (ILC2s) stimulated with IL33 and TL1A

Project description:We analyzed the total proteome of group 2 innate lymphoid cells (ILC2s) after different stimulation with interleukin-33 (IL-33), a cytokine playing a critical role in human asthma, and TL1A, a TNF-family cytokine also known to activate ILC2s. Upon combined stimulation with IL-33 plus TL1A, we show that lung ILC2s produce high amounts of IL-9 and acquire a transient ‘ILC9’ phenotype. This phenotype is characterized by simultaneous production of large amounts of type 2 cytokines (IL-5, IL-13 and IL-9), induction of the IL-2 receptor CD25 (Il2ra), and of the transcription factors IRF4, JunB and BATF, that form immune-specific complexes known to induce IL-9 expression.

Microarray transcription of murine lung and uterine group 2 innate lymphoid cells (ILC2s) cultured in vitro with or without 17beta-estradiol (estrogen, E2)

Project description:This experiment sought to determine whether estrogen could directly activate changes in gene transcription in lung and uterine ILC2s, whether such changes differed between lung and uterine ILC2s, and compared baseline gene expression between ILC2s from those organs. ILC2s, defined as lineage (CD3e, CD14, CD16/32 and B220) negative, CD25 positive and CD44 high lymphocytes, were sorted by flow cytometry from 8-12 week old BALB/c mice and cultured overnight in RPMI 1640 with 10% charcoal/dextran treated calf serum in the absence or presence of 100 ng/ml estrogen. RNA was extracted from the cells after culture.

Transcriptome of human ILC2s; primary vs IL-1b-primed

Project description:ILC2s regulate type2 immune responses and protect against helminth infection. We found that ILC2s can be expanded in the presence of a combination of cytokines IL-2 and IL-1b. To better understand the functional and phenotypic consequence of IL-1β activation of ILC2s, we utilized whole transcriptome sequencing (RNA-seq) of freshly isolated ILC2s and IL-1β-primed ILC2s. Differential expression analysis revealed a substantial number of genes underwent significant change between the two conditions (total 4,744 gene, FDR<0.01, Fold change >2), among which 3,871 genes were upregulated in IL-1β –primed ILC2s.

Transcription factor Bcl11b controls identity and function of mature innate lymphoid cells type II

Project description:Type-2 innate lymphoid cells (ILC2s) promote anti-helminth responses and contribute to allergies. Though Bcl11b has been previously considered a T-lineage identity transcription factor (TF) that restrains the innate-cell genetic programs, we report here that Bcl11b is highly expressed in mature ILC2s and acts upstream of the key ILC2 TFs Gfi1, Gata-3, and of IL-33 receptor IL1rl1 (T1ST2). Additionally, Bcl11b-/- ILC2s de-repressed Rorγt, Ahr and IL-23 receptor, normally expressed in type-3 ILCs (ILC3s). Consequently, Bcl11b-/- ILC2s lost ILC2 functions and gained ILC3 functions, expanding in response to the protease allergen papain, however producing IL-17 and IL-22, and not IL-5 and IL-13, causing lung neutrophilia rather than eosinophilia, and diminished mucus production. Our results broaden Bcl11b's role from a T-cell only TF, and establishes that Bcl11b sustains mature ILC2 genetic and functional programs and lineage fidelity through positive regulation of essential ILC2 TFs and negative regulation of pivotal ILC3 TFs. RNA-seq analysis on sorted ILC2s from the mLNs of Bcl11bF/F Cre-ERT2 and wildtype mice at steady state following tamoxifen mediated deletion of Bcl11b
