Figure 5From: Immunohistochemical characterization of nodose cough receptor neurons projecting to the trachea of guinea pigsRepresentative photomicrographs showing nodose neurons retrogradely labeled from the trachea with fluorogold (FG) overlaid with immunoreactivity for (A) α1 Na+/K+ ATPase, (B) α3 Na+/K+ ATPase, (C) vGlut1, (D) vGlut2, (E) NKCC1 or (F) negative control (neg). In panels A and B, the arrows point to FG traced neurons that are immunoreactive for α1 or α3 Na+/K+ ATPase, the arrow heads show traced neurons that are not immunoreactive for α1 or α3 Na+/K+ ATPase and the asterisks show FG-negative neurons that are immunolabeled for α1 or α3 Na+/K+ ATPase. Traced neurons appear red in panel A as the tissue underwent secondary immunoprocessing for FG. Scale bar represents 40 μm.Back to article page
