Expression of the EP2 receptor (green) in the DRG. On day 1, co-labeling for EP2 and neurons (MAP2; red) demonstrates that EP2 expression after sham (A) is less than after painful joint injury (B) and that most EP2 is found in neurons. The boxed area in (B) is magnified in (C) to highlight the neuronal expression of EP2. Similarly, on day 7, EP2 expression after sham (D) is less than after joint injury (E). EP2 expressed in the DRG of naïve rats served for comparison (F). Scale bars in (C) and (F) are 20μm. Scale bar in (F) applies to panels A–B and D–F. Nuclei are shown in blue.
