Purpose: The goalsof this study was to compare the transcriptome profiling of dorsal root ganglia (DRG) of animals injected intrathecally with IL4-10 FP, the combination of IL4+IL10 or vehicle, one week after induction of persistent inflammatory pain. Methods: Mice received an intraplantar injection of carrageenan and one week developing inflammatory pain were intrathecally injected with IL4-10 FP, IL4+IL10 or PBS. DRGs were isolated and RNA libraries were prepared with the poly A selection method followed by multiplexing and sequencing on the Illumina NextSeq500® platform in a 1 × 75bp single-read and 350 million reads per lane (Utrecht Sequencing Facility) Results: In vivo IL4-10 FP induces a differential transcriptome than the combination of cytokines in mice with persistent inflammatory pain. Conclusions: The superior analgesic effect observed in mice treated with IL4-10 FP compared to mice injected with the naïve cytokines is derived from an induction of a different transcriptome on the lumbar DRGs. Overall design: RNA was extracted from lumbar DRGs of mice injected intrathecally with IL4-10 FP (n=6), IL4+IL10 (n=5) or PBS; a week after induction of persistent inflammatory pain. Less...
