NADPH-diaphorase expression in the hypothalamo-hypophysial system of different catfish.
The distribution of NADPH-d activity was studied in the hypothalamus and in the pituitary gland of 15 species of catfish. Seven hypothalamic nuclei, four fiber bundles, as well as cells located in the adenohypophysis were labeled by NADPH-d histochemistry. Reactive somata were found in the nucleus praeopticus periventricularis, the paraventricular division of the nucleus praeopticus, the supraoptic division of the nucleus praeopticus, the nucleus lateralis tuberis, the paraventricular organ, the nucleus recessus lateralis, the nucleus recessus posterioris, and in the adenohypophysis. In some species, an inconsistent number of these structures lacked NADPH-d activity. These results are compatible with the notion that NADPH-d activity expressing cells in the hypothalamus and in the pituitary are involved in the control of hormone regulation.
