Project description:Purpose: To understanding the effects of RORa deficiency on ILC1 cells, we conducted bulk mRNA-seqencing Method: Firstly, we purified liver ILC1 cells (CD45.2+CD3-CD19-NKp46+NK1.1+CD49a+CD49b-) via Fluorescence Activated Cell Sorting, then frozen in -80 °C ultra-low temperature refrigerator, followed by High-throughput sequencing, in three replicates for WT (Rorafl/fl) mice and one replicate for cKO (Ncr1Cre-Rorafl/fl) , using Illumina Hiseq 1500 platform.

Project description:Innate lymphoid cell (ILC) subsets that mirror helper T cells in their effector cytokine profiles have recently emerged as central players in both homeostatic and inflammatory conditions. Like their Th1, Th2 and Th17/Th22 helper T cell counterparts, ILC subsets are categorized based on their expression of specific transcription factors and effector cytokines: group 1 ILC (ILC1) express T-bet and IFN-γ; group 2 ILC (ILC2) express GATA-3 and type 2 effector cytokines such as IL-13 and IL-5; and group 3 ILC (ILC3) express RORgt and the cytokines IL-22 and/or IL-17. Under this nomenclature, natural killer (NK) cells and lymphoid tissue inducers (LTi) are considered ILC1 and ILC3, respectively. ILC1 contain both CD4+ and CD4- populations, but whether this phenotypic characteristic reflects functional differences between these two populations is unknown. These studies examine the gene expression profiles of CD4+ vs CD4- ILC1 in a cohort of healthy control subjects. ILC subsets were isolated from the peripheral blood of healthy control subjects. cDNA was isolated and amplified from sorted populations, and gene expression was analyzed by RNAseq

Project description:Innate lymphoid cells (ILCs) mediate early immunity against infection and participate in tissue inflammation and homeostasis. It is unclear how ILCs acquire effector function, and whether these mechanisms differ between organs. Through multiplexed single-cell mRNA-sequencing we identified cKit+CD127hiTCF-1hi early differentiation stages of T-bet+ ILC1. These cells were present across different organs and had the potential to mature towards CD127intTCF-1int and CD127-TCF-1- ILC1. Paralleling a gradual loss of TCF-1, differentiating ILC1 forfeited their expansion potential while increasing expression of effector molecules, reminiscent of T cell differentiation in secondary lymphoid organs. The transcription factor Hobit was induced in TCF-1hi ILC1s and was required for their effector differentiation. These findings reveal sequential mechanisms of ILC1 lineage commitment and ILC1 effector differentiation that are conserved across tissues. Our analyses suggest that ILC1 emerge as TCF-1hi cells in the periphery and acquire a spectrum of organ-specific effector phenotypes through a uniform Hobit-dependent differentiation pathway driven by local cues.

Project description:Innate lymphoid cells (ILCs) are able to directly respond to alarmin signals and produce an array of effector molecules for immune protection and tissue homeostasis. However, how posttranscriptional machinery in ILCs execute extracellular stimuli towards robust gene expression is yet to understand. Here, we reported a cell type-specific role of N6-methyladenosine (m6A) RNA methylation in ILCs. Inducible deletion of m6A methyltransferase METTL3 had little impact on ILC maintenance in the steady state or cytokine-induced ILC1 or ILC3 activation, but dramatically diminished IL-25-triggered ILC2 response. Specific deletion of Mettl3 in ILC2 significantly attenuated cell expansion, cytokine production, inter-organ migration, and anti-helminth immunity. To investigate the molecular mechanism by which m6A modification regulates ILC response, we subjected IL-12 plus IL-18-activated ILC1 to a m6A-tagged mRNA immunoprecipitation sequencing (meRIP-seq) to identify the m6A modified mRNA.

Project description:Innate and adaptive immune cells can acquire “memory” of encounters with a diverse range of activating signals to tune their response to secondary stimuli. Group 1 innate lymphoid cells (ILC1) are recently discovered tissue-resident sentinels that are essential for early host protection from intracellular pathogens at initial sites of infection. However, whether ILC1 function as short-lived effectors or persist and refine their responsiveness following pathogen challenge is not well understood. Furthermore, whether pathogen-derived antigens directly modulate tissue-resident ILC responses remains unclear. Here, we found that liver-resident ILC1 expand locally and persist following the resolution of mouse cytomegalovirus (MCMV) infection. MCMVexperienced ILC1 acquired stable transcriptional, epigenetic, and phenotypic changes, with an enhanced protective effector response to secondary MCMV challenge. Protective memory ILC1 responses were dependent on the MCMV-encoded glycoprotein m12, but not formed during bystander cytokine activation following heterologous infection. Thus, liver ILC1 acquire adaptive features in a MCMV-specific manner.

Project description:Natural killer (NK) cells and type 1 innate lymphoid cells (ILC1) require the transcription factor STAT4 to elicit rapid effector responses and protect against pathogens. Herein, by combining genetic and transcriptomic approaches, we revealed that STAT4 played an unexpected divergent role in regulating effector differentiation of murine ILC1 and NK cells, during intestinal inflammation. Stat4 deletion in Ncr1-expressing cells led to an increased generation of cytotoxic ILC1 in the inflamed large intestine. By contrast, Stat4-deficient NK cells showed impaired terminal differentiation, characterized by lower levels of IRF-8 and KLRG1. STAT4 expression in NCR+ innate lymphocytes restrained gut inflammation and controlled both systemic IFN-g levels and the number of type 2 adaptive T cells in the large intestine. Collectively our data shed light on shared and distinctive mechanisms of transcriptional regulation driven by STAT4 in NK cells and ILC1 required for protection during intestinal inflammation.
