Sample preparation and analysis of RNA-Seq data:

…Cells were centrifuged (400g for 15 minutes at 4C), supernatant was collected, and BAL total cell counts and differentials were performed from cytospins. BAL samples from five of the healthy volunteers (samples 1115, Table 1) were cultured with RPMI1640 + 10% human AB serum and supplemented with 1% Antibiotic-Antimycotic (Life Technologies), with or without ultrapure LPS 100 ng/ml (E. coli 0111:B4, List Biological Laboratories, Cat# 421, Lot# 4217A1) at 37C and 5% CO₂ for 6 hours. Ultrapure LPS was chosen to minimize possibility of contamination by other bacterial components [1]. Previous studies have used concentrations of LPS ranging from 10 ng/ml-1000 ng/ml [1214]. The cell culture supernatants were collected and stored at -80C for later use. Total RNA was extracted by miRNeasy Mini Kit (Qiagen). …
