| Extracted molecule |
total RNA |
| Extraction protocol |
The samples collected pre- and post-challenge were frozen and transported to the laboratory on dry ice, where they were stored at –80°C until RNA extraction.
From 8 PAXgene Blood RNA tubes (PreAnalytiX – Qiagen / BD, Valencia, CA, USA), total intracellular RNA was purified from 2.5 mL of whole-blood according to manufacturer protocols using the RNeasy mini kit (Qiagen, Chatsworth, CA, USA).
The yield and quality of RNA was assessed by NanoDrop 8000 Spectrophotometer (Thermo Scientific, Wilmington, DE, USA) and Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA)

| Data processing |
Raw data normalization using the 'farms' package consisted of quantile normalization and summarization of probe-level data.
Data filtering was also performed using the Informative vs. Non-Informative Calls function in the 'farms' package. Differential gene expression was determined using moderated t-tests in limma using an FDR cut-off of 5%.
All statistical analyses were performed in the statistical computing program R.
