(A) Schematic of superposition of sensory neuron somata and satellite glial cells (SGCs) within the dorsal root ganglion (DRG). (B) Detection of Dbi mRNA expression in human and mouse DRG by reverse transcription (RT) PCR. (C–E) Sections of human (C), rat (D), and mouse (E) DRGs with sensory neuron somata identified with Nissl (green) staining; DBI…
