Figure 5. PGP9.5 and TH immunofluorescense demonstrated colabeling and decreased expression in cardiac nerve bundles of 6-OHDA monkeys.

Microphotographs of immunofluorescence staining of PGP9.5 (red; A,E), TH (green; B,F) and counterstained with DAPI (blue nuclei; C,G) in controls (A–D) and 6-OHDA-treated animals (E–H). Colocalization of PGP9.5 and TH expression is identified as yellow. PGP9.5, protein gene product 9.5; TH, tyrosine hydroxylase.
