ATP Activates OSNs Expressing a Novel Adenosine Receptor A2c
(A) Double fluorescence in situ hybridization for c-Fos (green) and ORs, V1Rs, V2RL1, or TAARs (magenta) on OE sections of 1 mM ATP-exposed fish (n = 3). No double-positive OSNs are observed. See also Table S1.
(B) Double fluorescence in situ hybridization for c-Fos (green) and A2c (magenta) on OE sections of 1 mM ATP-exposed fish (n = 4). Note that all c-Fos-positive OSNs express A2c mRNA. Inset: a magnified view of the boxed region.
(C) Double fluorescence in situ hybridization for A2c (magenta) and Golf or ACIII (green) on OE sections (n = 3). A2c-positive OSNs express Golf and ACIII mRNA. Insets: magnified views of the boxed regions.
