Abstract
- The present study investigates the occurrence of Trk-like neurotrophin receptor proteins in the lizard and frog kidney. In lizard rare TrkB-like immunoreactive cells in intermediate and distal tubules were found. TrkC-like immunoreactive cells were numerous in collecting tubules and became less numerous in collecting ducts. No TrkC-like immunoreactivity was detected in the ureteric duct. In the frog, we observed numerous TrkC-like immunoreactive cells in collecting tubules and ducts while they were scattered among negative epithelial cells in the wolffian duct. TrkB- and TrkA-like immunoreactivity was never found. Western blot analysis demonstrated that the frog and lizard kidney contains TrkC-like protein; TrkB-like protein was present only in the lizard kidney. These results demonstrate for the first time the occurrence of Trk-like proteins in the kidney of amphibians and reptiles, and aid in the assessment of the role of Trk receptor-like proteins in the kidney physiology of vertebrates.
