Dear all, It is our great pleasure to announce next BCO seminars by Dr. Vincent Prevot: The seminar will explore: "Semaphorin 3A/Neuropilin-1 Signalling in GnRH system development and adult plasticity”
Date: Thursday 24/4 at 15.15 Location: Lecture hall A101
In addition, you might be interested to have separate meeting with Vincent Prevot. Do not hesitate to connect me (sylvain.sebert@oulu.fimailto:sylvain.sebert@oulu.fi) or Tuire (tuire.salonurmi@oulu.fimailto:tuire.salonurmi@oulu.fi) ### SOME INFO ABOUT VINCENT PREVOT ### Vincent Prevot, Director of Research, Ph.D. in Neuroscience, University of Lille, France Head of the Inserm Research Team “Development and Plasticity of the Postnatal Brain”, Inserm U837, Jean-Pierre Aubert Research Centre. Lille, France
The research undertaken in Vincent Prevot Laboratories uses a combination of genetic, primary cell culture and co-culture, biochemical, electrophysiological, neuroanatomical, immunofluorescent, electron microscopy, advanced imaging techniques and physiological approaches. The research focuses on the study of:
- Neuronal-glial-endothelial communication processes regulating GnRH neurosecretion,
- endothelial and neuronal nitric oxide signaling, glial erbB signalling,
- onset of puberty, ovarian cycle-induced brain plasticity and reproduction. In parallel, Vincent Prevot’s research has interest in studying the role of peripheral hormones (estrogen, leptin, insulin…) on hypothalamic development and function as well as in determining the importance of non-neuronal cells (tanycytes, astrocytes and endothelial cells) in the communication between the peripheral organs and the central nervous system. Finally, the researches also evaluate how pathologies (such as obesity, diabetes) may affect these neurobiological events and, conversely, how impairment of brain communication with the periphery renders the organism prone to develop pathologies (obesity, diabetes, precocious and/or delayed puberty, and infertility).
