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)
An antiserum raised against the FMRFamide peptide revealed a highly developed peripheral nervous system in the mollusc Helix aspersa. Immunoreactive fibres associated with muscular fibres are observed in all organs. Cell bodies are frequently seen, for example in the digestive and genital tracts. The antiserum also revealed associations between(More)
The Mycobacterium tuberculosis Ser/Thr kinase PknB has been implicated in the regulation of cell growth and morphology in this organism. The extracytoplasmic domain of this membrane protein comprises four penicillin binding protein and Ser/Thr kinase associated (PASTA) domains, which are predicted to bind stem peptides of peptidoglycan. Using a(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)
In the Rat, immunoreactive CRF-containing processes appear in the median eminence between the 18 and the 19th day of the fetal development. They seem to become functional as early as the 19th day since they establish neuro-hemal junctions with the capillaries of the Mantel Plexus. During the pre- and post-natal periods, the number of these fibers increases(More)
A new peptidergic paraventriculo-infundibular system has been revealed using anti-corticoliberin (CRF) antibodies. The localization of its perikarya in the paraventricular nuclei as well as the distribution of its fibres and perivascular nerve-endings within the median eminence are different from those of other systems stained with antibodies directed(More)
Melanin-concentrating hormone (MCH)-like producing neurons were mapped in the brains of several reptiles using antisera (AS) prepared against salmon MCH (sMCH) and peptides derived from the rat MCH precursor (rMCH, NGE, NEI) or cross-reacting with these peptides (anti-GRF37 and anti-alpha-MSH). MCH neurons were detected in the periventricular and lateral(More)
