title: Neuromedin B-like immunoreactivity in the brain of the green frog (Rana esculenta L.).
abstract: Three rabbit polyclonal antisera, originally developed against neuromedin B and highly selective against ranatensin subfamily molecules, were used to study the distribution of neuromedin B-like immunoreactivity in the brain of Rana esculenta. Immunopositive cell bodies were observed in several brain regions, including medial and lateral septal nuclei, nucleus of the diagonal band of Broca, medial amygdala, ventral striatum, ventromedial and posterior thalamic nuclei, nucleus of the periventricular organ, posterior tuberculum, dorsal, lateral and ventral hypothalamic nuclei, optic tectum, mesencephalic tegmentum and central rhomboencephalic gray. A dense network of immunopositive fibers was also distributed in defined regions of the frog brain, i.e. in the medial pallium, septum, amygdala, ventral thalamus, preoptic area and posterior hypothalamus. The results of the present study, taken with available molecular biology data, indicate that the naturally occurring antigen is probably represented by a ranatensin/litorin-related antigen.
