NMB is specifically expressed in a subset of TG and DRG neurons and is undetectable in the GG. ISH reveals that Nmb (a, d, g) and Calcb (b, e, h) are expressed in the TG (a–c) and DRG (g–i), but are undetectable in the GG (d–f). In contrast, the ionotrophic ion-channel P2Rx3 is expressed in all ganglia (c, f, i). ISH of sections through the spinal cord (j–l) establishes that Nmb (j) is not expressed, while Tac1 (k) and GRP (l) are found in a small number of interneurons in the dorsal horn.
