Nav1.7 is expressed in human DRG neurons. Representative IHC images show that Nav1.7 colocalizes with TRPV1 and CGRP. A–F, Nav1.7 alone (red; A, B), TRPV1 (C), and CGRP (D) are shown alone in green, and E and F show the colocalization (yellow/orange). The bar graphs in G and H show the group summaries of the IHC data. Scale bar, 100 μm.
