Datasets of 16S rRNA gene amplicon sequences, metabolites, and soluble immune components in bronchoalveolar lavage samples from severe asthmatic and age-matched control children

Sep 29, 2026

Severe asthma in children is a heterogeneous condition with distinct phenotypes and endotypes. This dataset describes microbiota, metabolites, and soluble immune components measured in bronchoalveolar lavage (BAL) fluids from children with severe asthma and age-matched controls. It provides the complete workflow and data outputs for BAL processing, 16S rRNA gene amplicon sequencing and bioinformatics, untargeted metabolomics analysis, and immune component assays, enabling multi-omics exploration of disease mechanisms and local biomarkers.

FAQs

What types of biological data are included in these bronchoalveolar lavage datasets?

The datasets include 16S rRNA gene amplicon sequencing data, untargeted metabolomics results, and concentrations of soluble immune components measured in BAL samples.

How were the BAL samples collected and processed for analysis?

Bronchoalveolar lavage samples were collected during endoscopy, followed by purification of DNA libraries and sequencing of amplicons, alongside metabolomics measurement by LC–HRMS and immune component assays.

What downstream analyses does the article’s dataset support?

The provided data and associated processing steps support multi-omics investigations of severe asthma mechanisms, identification of local signatures, and comparisons with other cohorts or reference uses for related pulmonary diseases.
