Aim: We performed a transcriptomic analysis of affected dorsal root ganglions in mice following a partial thickness locl burn injury on the left hind feet to gain a better understanding of the molecular changes that accompany burns painMethods: Male C57BL/6 mice aged 6-8 weeks were sacrificed three days after the burn injury and lumbar dorsal root ganglions L3, L4, and L5 were extracted. Four animals were pooled together to form one biological replicate, and samples were gathered in triplicates. Sequencing was conducted on Illumina NextSeq 500 as 75-nucleotide single-end runs and libraries wre prepared using TruSeq stranded total RNA library preparation. Reads were mapped using STAR aligner and samtools, mapped to mm10 (Ensembl), and count tables generated using HTSeq_countResults: We discovered 30 genes differentially expressed following the burns injury in dorsal root ganglions, among which are Atf3, Npy, Lipn, and others. We identified Cckbr and Grin2b as potential pharmaceutical targets for pain.Conclusion: Neurons undergo mainly an inflammatory and regenerative process following a local burn and enriched neuropeptide signalling processes. Cckbr and Grin2b in particular were identified as potential targets in the treatment of burns pain together with other genes identified in our study
