Abstract
A double immunocytochemical procedure, with two different chromogens, was used to compare the respective distributions of estrogen receptor‐immunoreactive cells and gonadotrophin‐releasing hormone‐immunoreactive neurons on the same sections of the brains of adult male and female rainbow trout (Oncorhynchus mykiss). Estrogen receptor‐immunoreactive cells were observed in the ventral and lateral telencephalon, the preoptic region, the mediobasal hypothalamus, and the ventromedial thalamic nucleus. Gonadotrophin‐releasing hormone immunoreactive perikarya were detected in the olfactory bulbs, the ventral telencephalon, the preoptic area, and the mediobasal hypothalamus. Double‐staining studies showed that, although some estrogen receptor‐positive cells were in close proximity to gonadotrophin releasing hormone‐immunoreactive perikarya, careful examination of 550 gonadotrophinreleasing hormone‐positive cells from five adult females and two adult males failed to demonstrate any evidence that gonadotrophin‐releasing hormone neurons coexpress estrogen receptor in the brain of the rainbow trout. The present study provides, for the first time in teleosts, morphological evidence that gonadotrophin‐releasing hormone neurons do not represent major direct targets for estradiol, suggesting that the positive feedback effects of estradiol onto the gonadotrophin‐releasing hormone system are likely to be conveyed via other cell populations. © 1995 Wiley‐Liss, Inc.
