Abstract

Contents: Orexin A and B, also known as hypocretin A and B, are hypothalamic neuropeptides arising from a precursor to the 130 amino acid, called pre–pro orexin. They are synthesized mainly in lateral and posterior hypothalamus and are involved in different functions such as regulation of food intake and energy balance. Orexins and orexin receptors were previously described also in different tissues and organs outside the brain. The aim of this study was to demonstrate by means of the immunofluorescence technique, the presence of orexin A in the ovary of cat and dog, to support the hypothesis of the role of this substance also at the level of the female genital system. The presence of orexin A in the ovary either in dog or in cat is in agreement with previous data on the presence and role of orexins in the female genital system of other species.
