Development of the paraventriculo-infundibular corticoliberin system was studied by immunocytochemical analysis of human hypothalamic sections using antisera raised against rat or ovine corticotropin-releasing factor (CRF). This comparative study confirms the presence of a significant number of CRF-immunoreactive fibers in the median eminence during the(More)
In the central nervous systems of several species belonging to different vertebrate classes, immunocytochemical stainings with an antiserum to ovine CRF 41 show multiple location of CRF perikarya and various areas containing CRF fibres and terminals. These stainings reflect species and interspecies functional adaptations of the CRF neurones which constitute(More)
BACKGROUND The hypothetical responsibility of sperm donation in cytomegalovirus (CMV) transmission to recipients and precautions to prevent this transmission are widely discussed. The aim of this French CECOS Federation study was to evaluate both the reality and the importance of the CMV risk due to donor sperm and the relevance of measures used to screen(More)
Human posterolateral hypothalamic neurons are revealed with an anti GRF 37 serum as soon as the 7th week of fetal life. The same neuronal population can be observed in the adult brain even in hypothalami from old subjects, with the same distribution, and similar immunoreactivity than in fetal stages. These neurons are revealed using a melanin concentrating(More)
Using the indirect immunofluorescence technique, an antiserum to synthetic hpGRF 44 (the 44 residue peptide with high growth hormone releasing activity isolated from a human pancreatic tumor), antibodies of which interact with 40-44 C terminal amino acid sequence, stains a novel neuron system in the adult human hypothalamus. HpGRF-like immunoreactivity(More)
In the human fetus, the first anti CRF-stained fibres appear in the median eminence during the 16th week. From the 17th week, they are more numerous and they establish neurohemal terminals close to the superficial capillaries and around some of the developing intra-eminential vascular loops. In new born infants infundibular CRF-containing processes and(More)
In human fetus, newborn, infant and adult hypothalami, antibodies to ovine corticoliberin-41 stain a paraventriculo-infundibular neuroglandular pathway. The perikarya are located in the paraventricular nucleus, they mainly project to the ventral and lateral areas of the median eminence. Eminential corticoliberin-positive fibres appear during the 16th week(More)
An antiserum raised against synthetic salmon melanin-concentrating hormone (MCH) reveals an extensive neuronal system in the posterior lateral areas of the human hypothalamus. These neurons correspond to those previously described in the rat, which are characterized by expression of MCH-like, alpha-melanotropin-like and human growth hormone-releasing factor(More)
In the rat hypothalamus, antibodies to ovine CRF41 stain neurons of a paraventriculo-infundibular neuroglandular pathway. CRF like immunoreactivity (CLI)-containing perikarya are mostly packed in the parvocellular division of the paraventricular nucleus. Their morphology and topography differ from that of other peptidergic neurons. However a few CLI(More)
