RNA-seq analysis of bead-purified B cells of 5-week-old TLR9-/- MRL/lpr mice stimulated in vitro with TLR7 agonists (CL097, invivogen) or left unstimulated.
Purpose: The goal of this study was to develop a B-cell specific gene signature to catalog induced genes after short term in vitro TLR7 stimulation of TLR9-/- MRL/lpr B cells. Methods : Bead purified B cells (5M) from three 5-week-old TLR9-/- MRL/lpr mice were stimulated for 4 hours at 10M/ml with TLR7 agonist CL097 (Invivogen) at 5µg/ml or left unstimulated. RNA was isolated using the RNeasy Plus Mini Kit (QIAGEN). Samples were sequenced on an NextSeq500 (Illumina, Inc) with 2 x 75 bp paired-end reads (20 million reads per sample). Results: a B-cell specific gene signature of induced genes after short term in vitro TLR7 stimulation was cataloged. Overall design: mRNA profiles of TLR9 deficient (TLR9-/-) B cells stimulated in vitro with TLR7 agonists (CL097, Invivogen) or unstimulated, were generated in three replicates, by sequencing on an Illumina NextSeq500 using PE 150 Cycles High Output flowcell.
