Role of IL-33/ILC2 in bladder infection

Project description:The impact of IL-33 on urinary tract infections (UTI) was assessed by comparing Il33KO mice with wild-type (WT) mice within the bladder;The effect of ILC2 on UTI was assessed by comparing Il5cre+/DTA+ mice with WT mice within the bladder.

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.

Homeostatic leukotrienes, IL-25, and IL-33 signals on intestinal ILC2 status

Project description:We report the high-throughput profiling of murine intestinal type 2 innate lymphoid cells (ILC2) transcriptome. By obtaining over 8.7 million bases of sequence, we generated genome-wide expression maps of mouse ILC2 without the presense of known activation signals(IL-25, IL-33 receptor) and new non-redundant signal (leukotriene). We find that homeostatic signaling minimally contributes to intestinal ILC2 activation statu. 500 ILC2s were sorted as CD45+Lineage-IL-17RB+

RNA-sequencing of microglia, T cells and ILC2 from the brains of IL-33 treated aged (20-22mos) mice

Project description:ILC2 are potent producers of IL-5 and IL-13 and Th2 cytokines have been found to promote neurogenesis and cognitive functions. We report microglia, brain T cells and ILC2 have a range of differentially expressed genes in IL-33 treated aged mice. Brain ILC2 upregulated a range of neuroprotective genes.

scRNA-sequencing of ILC2 sorted from the choroid plexus and meninges of IL-33 treated aged (20-22 mos) mice

Project description:ILC2 are potent producers of IL-5 and IL-13 and Th2 cytokines. We have found that they promote neurogenesis and cognitive functions in aged mice . We report that CP and meningeal ILC2 from IL-33 treated aged mice have differential expression of Th2 cytokines as well as genes involved in metabolism through scRNA-sequencing.

Analysis of wild type and Sema6d-/- lung ILC2 transcriptomes in IL-33 induced acute lung inflammation

Project description:Semaphorin 6D (Sema6D) have various effects in immune responses. However, the involvement of Sema6D in ILC2 funcions remains unclear. We identified the genes regulated by Sema6D in lung ILC2s during IL-33 induced acute lung inflammation.

IL-33 causes thermogenic failure in aging by expanding dysfunctional adipose ILC2 [bulk rnaseq]

Project description:Aging impairs the integrated immunometabolic responses which have evolved to maintain core body temperature in homeotherms to survive cold-stress, infections, and dietary restriction. Adipose tissue inflammation regulates the thermogenic stress response but how adipose tissue-resident cells instigate thermogenic failure in the aged are unknown. Here, we define alterations in the adipose-resident immune system and identify that type 2 innate lymphoid cells (ILC2) are lost in aging. Restoration of ILC2 numbers in aged mice to levels seen in adults through IL-33 supplementation failed to rescue old mice from metabolic impairment and increased cold-induced lethality. Transcriptomic analyses revealed intrinsic defects in aged ILC2, and adoptive transfer of adult ILC2 are sufficient to protect old mice against cold. Thus, the functional defects in adipose ILC2 during aging drive thermogenic failure.
