(Submitter supplied) Asthma is the most common chronic pulmonary disease in children. The pathogenesis of asthma is not fully understood,and existing treatments have little effect on some children.MicroRNAs(miRNAs) play a regulatory role in the occurrence and development of asthma,and miRNA therapy is a promising treatment for asthma.The purpose of this study was to explore the differential expression of miRNAs in peripheral blood of children with asthma and to find a miRNA that can alleviate asthma inflammation.We used high-throughput sequencing to analyze miRNA differences in peripheral blood between children with acute asthma attacks and healthy children,target gene prediction and functional enrichment analysis were performed for them..Overall,51 differentially expressed miRNAs were identified,with 9 being upregulated and 42 downregulated.

(Submitter supplied) 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. more...

(Submitter supplied) Group 2 innate lymphoid cells (ILC2s) play a crucial role in allergic diseases by coordinating a complex network of various effector cell lineages involved in type 2 inflammation. However, their function in regulating airway neutrophil infiltration, a deleterious symptom of severe asthma, remains unknown. Here, we observed ILC2-dependent neutrophil accumulation in the bronchoalveolar lavage fluid (BALF) of allergic mice models. more...

(Submitter supplied) To study modulators of inflammatory airway disease, we developed an in vitro bronchial epithelial cell model system based on the BEAS-2B cell line exposed to lipopolysaccharide (LPS) and diesel exhaust particles (DEP). Combined LPS and DEP exposure triggered a molecular inflammatory phenotype, including elevated TSLP and IL-8 mRNA expression, similar to that observed in airway epithelial cells from asthma patients. more...

(Submitter supplied) Background: Adults with at least one copy of the minor allele in the rs6967330 SNP (AA/AG) in the rhinovirus (RV) receptor Cadherin related family member 3 gene (CDHR3), have a higher risk for CRS than those with two copies of the major allele (GG). Objective: To determine if the rs6967330 SNP increased the risk for acute exacerbations of chronic rhinosinusitis (AECRS) in adults and identify if their nasal cells showed a distinct pathophysiologic process activated by RV infection. more...

(Submitter supplied) Lung epithelial cells produce alarmins that promote allergic inflammation, however, the molecular mechanisms that regulate alarmin expression and production have not been fully elucidated. We constructed an integrated single-cell RNA-seq atlas of murine airways, lung, and vagal nerves, which we use to characterize novel lung cell subsets and infer intercellular interactions, including an interaction between podoplanin (PDPN) on alveolar epithelial cells and C-type Lectin-like Receptor-2 (CLEC-2/Clec1b) on alveolar macrophages that controls the expression of IL-33. more...

(Submitter supplied) IL-23-Th17 signaling axis is responsible for neutrophilic inflammation in various barrier tissues. However, mechanistic links between IL-23 and Th17 activation remain unclear, despite of their critical contribution to chronic inflammatory diseases. Here, we discovered a novel signaling pathway linking IL-23 to Th17 activation in our neutrophil-dominant asthma (NDA) model. Through single-cell multi-omics analysis, we identified distinctive CD39+CD9+ interstitial macrophages (IMs) suppressed by IL-23. more...

(Submitter supplied) Females have increased prevalence of many Th17-mediated diseases, including asthma. Androgen signaling decreases Th17-mediated airway inflammation, and Th17 cells rely on glutaminolysis. However, it remains unclear whether androgen receptor (AR) signaling modifies glutamine metabolism to suppress Th17-mediated inflammation. In this experiment, we conducted a CUT & RUN to determine how AR signaling modified histone 3 lysine 27 trimethylation in Th17 cells from WT males, WT females, and ArTfm male mice (n=3 from each group).

(Submitter supplied) Type-2 innate lymphoid cells (ILC2) are part of a growing family of innate lymphocytes known for their crucial role in both the development and exacerbation of allergic asthma. In this study, we aim to elucidate the critical role of the suppressor molecule signal regulatory protein alpha (SIRPα), which interacts with CD47, in controlling ILC2-mediated airway hyperreactivity (AHR). Our data indicate that activated ILC2s upregulate the expression of SIRPα, and the interaction between SIRPα and CD47 effectively suppresses both ILC2 proliferation and effector function. more...

(Submitter supplied) In this proof-of-concept study, we piloted a precision endotyping approach focused on DNA methylation biomarkers (CpG methylation) which are regulatory base modifications to DNA that influence cellular immune responses across the life course. The aims of this study were to (a) pilot a precision endotyping approach in a selected group of children from the Rochester prospective cohort who exhibited characteristics of high respiratory infection allergy/asthma prone (IAP) and low vaccine responsiveness (LVR) in early childhood, compared to non-respiratory infection allergy/asthma prone (NIAP) children and (b) assess whether stimulation of PBMCs with stimuli a vaccine adjuvant that activating activates a pattern recognition receptors (PRRs) could re-shape the epigenome.

(Submitter supplied) Rationale: DNA methylation plays a critical role in asthma development, but differences in DNA methylation associated with asthma severity, especially among adults, are less well-defined. Changes in DNA methylation are influenced by exposure to air pollution, which is a risk factor for asthma exacerbation and severity. Here, we examined how DNA methylomic patterns in adult asthmatics differ by asthma severity and exposure to different components of air pollution. more...

(Submitter supplied) Acute inflammatory exacerbations (AIEs) represent immune-driven deteriorations of many chronic lung conditions, including COPD, asthma, and pulmonary fibrosis (PF). The first line of therapy is represented by broad-spectrum immunomodulation. To better study immune cell heterogeneity during AIE-PF, this work leverages a clinically relevant model of inflammatory exacerbations triggered by mutation in the alveolar epithelial type 2 cell Surfactant Protein-C gene [SP-CI73T]. more...

(Submitter supplied) The beneficial effects of mesenchymal stem cell administration have been reported in numerous preclinical studies. Briefly, decreased levels of Th2-related cytokines, namely IL-4, IL-5, and IL-13, impaired eosinophils infiltration, and mucus secretion within the lung have been recognized as hallmarks of MSC-mediated immunosuppression in OVA-Alumn- induced experimental model. However, to date, the effects of MSCs transfer on mixed airway inflammation remain elusive. more...

(Submitter supplied) Murine counterpart of the region (mG900 region), in which SNPs associated with human asthma are enriched, is located 900 kb downstream from the transcription start site (TSS) of Gata3. Gata3-TSS interacted with mG900 region in only cultured Th2 cells but not in naive CD4 T cells or cultured Th0 cells. The mG900-deficient Th2 cells exhibited reduced interaction between Gata3-TSS and three enhancers.
