    Abstract Understanding the origins and developmental trajectory of innate lymphoid cell (ILC) progenitors has been of substantial interest to the fields of ILC biology and immunology. While mature ILC are rare lymphocytes, ILC progenitors represent an even smaller fraction of cells, providing additional challenges in studying them. Moreover, though the approaches to studying these cells are conceptually straightforward, the technical nuances that underlie them can substantially affect the quality of the data. Herein, we provide a detailed protocol for assessing the frequency of ILC progenitors in the bone marrow, their phenotype, and their potential to develop into mature ILC. These methods make up the foundation of in vivo investigations into ILC development, and we hope these thorough protocols and associated notes facilitate additional, high-quality inquiries into this fascinating field.

    Abstract Respiratory syncytial virus (RSV) is a leading cause of hospitalization of infants worldwide each year. Both host and viral factors host factors predispose a subset of what appear to be healthy infants to severe RSV-induced disease. In this review, we outline many genetic and immunologic factors that contribute to airway obstruction that contributes to the severity of RSV infection.

    Abstract Improved approaches to expanding the pool of donor lungs suitable for transplantation are critically needed for the growing population with end-stage lung disease. Cross-circulation (XC) of whole blood between swine and explanted human lungs has previously been reported to enable the extracorporeal recovery of donor lungs that declined for transplantation due to acute, reversible injuries. However, immunologic interactions of this xenogeneic platform have not been characterized, thus limiting potential translational applications. Using flow cytometry and immunohistochemistry, we demonstrate that porcine immune cell and immunoglobulin infiltration occurs in this xenogeneic XC system, in the context of calcineurin-based immunosuppression and complement depletion. Despite this, xenogeneic XC supported the viability, tissue integrity, and physiologic improvement of human donor lungs over 24 hours of xeno-support. These findings provide targets for future immunomodulatory strategies to minimize immunologic interactions on this organ support biotechnology.

    Abstract Strain-specific differences in susceptibility to mouse adenovirus type 1 (MAV-1) are linked to the quantitative trait locus Msq1 on mouse chromosome 15. This region contains 14 Ly6 or Ly6-related genes, many of which are known to be expressed on the surface of immune cells, suggesting a possible role in host defense. We analyzed these genes for polymorphisms between MAV-1-susceptible and MAV-1-resistant inbred mouse strains. Sequencing of cDNAs identified 12 coding-region polymorphisms in 2010109I03Rik, Ly6e, Ly6a, Ly6c1, and Ly6c2, six of which were nonsynonymous and five of which were previously unlisted in dbSNP Build 132. We also clarified sequence discrepancies in GenBank for the coding regions of I830127L07Rik and Ly6g. Additionally, Southern blotting revealed size polymorphisms within the DNA regions of Ly6e, Ly6a, and Ly6g. Collectively, these genetic variations have implications for the structure, function, and/or expression of Ly6 and Ly6-related genes that may contribute to the observed strain-specific differences in susceptibility to MAV-1.

    Abstract Background & aims: Severe injury to the lining of the stomach leads to changes in the epithelium (reprogramming) that protect and promote repair of the tissue, including development of spasmolytic polypeptide-expressing metaplasia (SPEM) and tuft and foveolar cell hyperplasia. Acute gastric damage elicits a type-2 inflammatory response that includes production of type-2 cytokines and infiltration by eosinophils and alternatively activated macrophages. Stomachs of mice that lack interleukin 33 (IL33) or interleukin 13 (IL13) did not undergo epithelial reprogramming after drug-induced injury. We investigated the role of group 2 innate lymphoid cells (ILC2s) in gastric epithelial repair.
    Methods: Acute gastric injury was induced in C57BL/6J mice (wild-type and RAG1 knockout) by administration of L635. We isolated ILC2s by flow cytometry from stomachs of mice that were and were not given L635 and performed single-cell RNA sequencing. ILC2s were depleted from wild-type and RAG1-knockout mice by administration of anti-CD90.2. We assessed gastric cell lineages, markers of metaplasia, inflammation, and proliferation. Gastric tissue microarrays from patients with gastric adenocarcinoma were analyzed by immunostaining.
    Results: There was a significant increase in the number of GATA3-positive ILC2s in stomach tissues from wild-type mice after L635-induced damage, but not in stomach tissues from IL33-knockout mice. We characterized a marker signature of gastric mucosal ILC2s and identified a transcription profile of metaplasia-associated ILC2s, which included changes in expression of Il5, Il13, Csf2, Pd1, and Ramp3; these changes were validated by quantitative polymerase chain reaction and immunocytochemistry. Depletion of ILC2s from mice blocked development of metaplasia after L635-induced injury in wild-type and RAG1-knockout mice and prevented foveolar and tuft cell hyperplasia and infiltration or activation of macrophages after injury. Numbers of ILC2s were increased in stomach tissues from patients with SPEM compared with patients with normal corpus mucosa.
    Conclusions: In analyses of stomach tissues from mice with gastric tissue damage and patients with SPEM, we found evidence of type 2 inflammation and increased numbers of ILC2s. Our results suggest that ILC2s coordinate the metaplastic response to severe gastric injury.

    Abstract Background: IL-33 is one of the most consistently associated gene candidates for asthma identified by using a genome-wide association study. Studies in mice and in human cells have confirmed the importance of IL-33 in inducing type 2 cytokine production from both group 2 innate lymphoid cells (ILC2s) and T
    Objective: We sought to determine the effect of glucagon-like peptide 1 receptor (GLP-1R) signaling on aeroallergen-induced airway IL-33 production and release and on innate type 2 airway inflammation.
    Methods: BALB/c mice were challenged intranasally with Alternaria extract for 4 consecutive days. GLP-1R agonist or vehicle was administered starting either 2 days before the first Alternaria extract challenge or 1 day after the first Alternaria extract challenge.
    Results: GLP-1R agonist treatment starting 2 days before the first Alternaria extract challenge decreased IL-33 release in the bronchoalveolar lavage fluid and dual oxidase 1 (Duox1) mRNA expression 1 hour after the first Alternaria extract challenge and IL-33 expression in lung epithelial cells 24 hours after the last Alternaria extract challenge. Furthermore, GLP-1R agonist significantly decreased the number of ILC2s expressing IL-5 and IL-13, lung protein expression of type 2 cytokines and chemokines, the number of perivascular eosinophils, mucus production, and airway responsiveness compared with vehicle treatment. GLP-1R agonist treatment starting 1 day after the first Alternaria extract challenge also significantly decreased eosinophilia and type 2 cytokine and chemokine expression in the airway after 4 days of Alternaria extract challenge.
    Conclusion: These results reveal that GLP-1R signaling might be a therapy to reduce IL-33 release and inhibit the ILC2 response to protease-containing aeroallergens, such as Alternaria.

    Abstract Mouse adenovirus type 1 (MAV-1) infection causes encephalitis in susceptible strains of mice and alters the permeability of infected brains to small molecules, which indicates disruption of the blood-brain barrier (BBB). Under pathological conditions, matrix metalloproteinases (MMPs) can disrupt the BBB through their proteolytic activity on basement membrane and tight junction proteins. We examined whether MAV-1 infection alters MMP activity
