Non-redundant functions of group 2 innate lymphoid cells

Project description:Here, we report the generation of a new mouse model based on the Nmur1 promoter as a driver for simultaneous expression of Cre recombinase and green fluorescent protein (GFP), which allows gene targeting in ILC2 without affecting other innate and adaptive immune cells. By removing Id2 and Gata-3 using Cre-mediated gene deletion in Nmur1-expressing cells, we have generated mice with selective and specific deficiency in ILC2. ILC2-deficient mice have decreased eosinophil counts in steady state and are unable to recruit eosinophils in the airways in models of allergic asthma. Further, ILC2-deficient mice fail to mount an appropriate immune and epithelial type 2 response resulting in a profound defect in worm control and a non-protective type 3 immune response. In total, our data establish non-redundant functions for ILC2s in the presence of adaptive immune cells at steady state and during diseases and argue for a multilayered organization of the immune system based on a spatiotemporal division of labor.

Role of a-DR3 on group 3 innate lymphoid cells

Project description:In order to examine the role of a-DR3 on group 3 innate lymphoid cells, we treated Rag1-/-Rorcgfp/+ mice with a-DR3 (4C12) and examine the gene expression in ILC3s with RNA-seq analysis.

RNA-Seq of Group 2 innate lymphoid cells (ILC2) from lung and lymph node

Project description:Group 2 innate lymphoid cells (ILC2) promote the production of a type-2 immunological environment in the uterus and have tissue-specific gene signatures that change with pregnancy.

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.

Group 3 innate lymphoid cells amplify YAP1-driven small intestinal repair

Project description:Ror gamma t-deficient mice lack group 3 Innate Lymphoid Cells (ILC3s) and as a result have increased tissue damage and diminished tissue repair in response to insult. To identify repair programs associated with ILC3 presence the transcriptomes of small intestinal stem cells exposed to damage in the presence or absence of ILC3 were compared. Small intestinal damage was induced in Ror gamma t-deficient Lgr5 reporter mice and littermate controls. Small intestinal epithelial stem cells were purified at days 1 and 4 after damage and subjected to RNA sequencing.
