Gene expression profiling of bone marrow and lung ILC2s

ABSTRACT: We found that CD45, a membrane bound tyrosine phosphatase important for T cell development, negatively regulated ILC2s in a cell-intrinsic manner. ILC2s in CD45-deficient mice exhibited enhanced proliferation and maturation in bone marrow and hyperactivated phenotypes in lung with alteration of cell metabolism.

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.

RNA sequencing of mesenteric lymph node ILC2s from non-treated mice

Project description:Transcriptomes of ILC2s sorted as KLRG1+CD127+CD90+Lin-CD45+ cells from mesenteric lymph nodes of non-treated mice were analyzed. The mice were part of the experiments described in PMID: 29496881 and were sequenced together with samples submitted in GSE108884.

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.

PAC1 constrains type II inflammation through promotion of CGRP signaling in ILC2s [scRNA-seq]

Project description:Dysfunction of group II innate lymphoid cells (ILC2s) plays an important role in the development of type II inflammation-related diseases such as asthma and pulmonary fibrosis. Notably, neural signals are increasingly recognized as pivotal regulators of ILC2s. However, how ILC2s intrinsically modulate their responsiveness to these neural signals is still largely unknown. Here, using single-cell RNA sequencing and bulk mRNA sequencing, we report that the immune regulatory molecule PAC1 (phosphatase of activated cells 1) selectively promotes the signaling of neuropeptide CGRP (calcitonin gene-related peptide) in ILC2s. Moreover, PAC1 is necessary for ensuring the expression of CGRP-response genes by influencing chromatin accessibility. In summary, our study demonstrates that PAC1 is an important regulator of ILC2 responses and we propose that PAC1 is a potential target for therapeutic interventions of type II inflammation-related diseases.

Transcriptome of sorted ILC2s in mice fed high-fiber and control diet

Project description:To determine the activation patterns of ILC2s and associated ILC2-intrinsic functional molecules triggered by the high fiber diet, we administered either a control or high fiber diet in WT mice and performed RNA sequencing of FACS-sorted ILC2s from mouse colons. RNAseq libraries were prepared from 1,000 sorted colonic lamina propria ILC2s (CD45+Lin-CD90.2+CD127+KLRG1+) by the Epigenomics Core at WCM using the Clontech SMARTer® Ultra® Low Input RNA Kit V4 (Clontech Laboratories). Libraries were sequenced on an Illumina HiSeq 2500, generating 50 bp single-end reads. Two samples from two control diet-fed WT SPF mice and two samples from two high fiber diet-fed WT SPF mice were used.

Human CD127 negative ILC2s show immunological memory.

Project description:Group 2 Innate Lymphoid Cells (ILC2s) are key players in type 2 immunity and contribute to maintaining homeostasis and responding to inflammation. ILC2s are implicated in the development of type 2 inflammation-mediated chronic disorders like asthma. While memory ILC2s have been identified in mouse, it is unknown whether human ILC2s can acquire immunological memory. Here, we demonstrate the persistence of CD45RO, a marker previously linked to inflammatory ILC2s, in resting ILC2s that have undergone prior activation. A high proportion of these cells concurrently reduce the expression of the canonical ILC marker CD127 in a tissue specific manner. Through isolation and in vitro stimulation of CD127- CD45RO+ ILC2s, we observed an augmented ability to proliferate and produce cytokines. CD127- CD45RO+ ILC2s are found in both healthy and inflamed tissues and display a gene signature of cell activation. Our findings suggest that human ILC2s can acquire innate immune memory and warrants a revision of the current strategies to identify human ILC2s.

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.
