The transcriptome of TRPV1-positive sensory neurons revealed by subgroup-elimination transcriptomics

We developed an approach to rapidly eliminate the subgroup of sensory neurons expressing the heat-gated cation channel TRPV1 from dissociated rat sensory ganglia using agonist treatment followed by density centrifugation. To identify transcripts predomintly expressed in TRPV1-positive neurons, we compared the transcriptome of all cells within sensory ganglia versus all cells without TRPV1 expressing neurons using RNA-Seq.
