P2Y4R immunoreactivity in BON cells. (A) Co-labeling of P2Y4 receptors (green) with 5-HT (red) in BON cells. P2Y4 is co-localized in a subset of BON cells expressing 5-HT immunoreactivity; arrowheads, co-localization of P2Y4 and 5HT immunoreactivities. (B) BON cells labeled for P2Y4 immunoreactivity (green) are counter-stained with DAPI (blue). P2Y4 immunoreactivity is localized around the cell nucleus.
