Journal ArticleDOI
Ultrastructural plasticity in the rat suprachiasmatic nucleus. Possible involvement in clock entrainment.
Denis Becquet,Clémence Girardet,Fabienne Guillaumond,Anne-Marie François-Bellan,Olivier Bosler,Olivier Bosler +5 more
TL;DR: Evidence is provided that the SCN undergoes rhythmic ultrastructural rearrangements over the 24‐h cycle characterized by day/night changes of the glial, axon terminal, and/or somato‐dendritic coverage of neurons expressing arginine vasopressin (AVP) or vasoactive intestinal peptide (VIP), the two main sources of SCN efferents.
Journal ArticleDOI
The food-contaminant deoxynivalenol modifies eating by targeting anorexigenic neurocircuitry.

Bonnet,Rajae Jdir,Medhi Sadoud,Sylvie Thirion,Catherine Tardivel,Catherine Tardivel,Julien Roux,Bruno Lebrun,Bruno Lebrun,Bruno Lebrun,Nicolas Wanaverbecq,Nicolas Wanaverbecq,Nicolas Wanaverbecq,Lourdes Mounien,Lourdes Mounien,Lourdes Mounien,Jérôme Trouslard,Jérôme Trouslard,Jérôme Trouslard,André Jean,André Jean,André Jean,Michel Dallaporta,Michel Dallaporta,Michel Dallaporta,Jean-Denis Troadec,Jean-Denis Troadec,Jean-Denis Troadec +32 more
TL;DR: The results strongly suggest that during intoxication, DON reaches the brain where it modifies anorexigenic balance, and may lead to reconsider the potential consequences of chronic DON consumption on human eating disorders.
Journal ArticleDOI
Central inflammation and sickness-like behavior induced by the food contaminant deoxynivalenol: a PGE2-independent mechanism.
Clémence Girardet,Marion S. Bonnet,Rajae Jdir,Medhi Sadoud,Sylvie Thirion,Catherine Tardivel,Julien Roux,Bruno Lebrun,Lourdes Mounien,Jérôme Trouslard,André Jean,Michel Dallaporta,Jean-Denis Troadec +12 more
TL;DR: It is shown that the toxin concomitantly affects feeding behavior, body temperature, and locomotor activity after both per os and central administration and reveals that, despite strong similarities, behavioral changes observed after DON intoxication differ from classical sickness behavior evoked by inflammatory cytokines.
Journal ArticleDOI
Daily changes in synaptic innervation of VIP neurons in the rat suprachiasmatic nucleus: contribution of glutamatergic afferents
Clémence Girardet,Marie-Pierre Blanchard,Géraldine Ferracci,Christian Lévêque,Mathias Moreno,Anne-Marie François-Bellan,Denis Becquet,Olivier Bosler +7 more
TL;DR: Data show that the light synchronization process in the SCN involves a selective remodelling of synapses at sites of photic integration, providing a further illustration of how the adult brain may rapidly and reversibly adapt its synaptic architecture to functional needs.
Journal ArticleDOI
Neuroglial and synaptic rearrangements associated with photic entrainment of the circadian clock in the suprachiasmatic nucleus
Clémence Girardet,Denis Becquet,Marie-Pierre Blanchard,Anne-Marie François-Bellan,Olivier Bosler +4 more
TL;DR: Experimental data providing strong indication that these plastic events may subserve synchronization of the clock to the light–dark cycle and that the daily fluctuations of plasma glucocorticoid hormones may act as temporal endocrine signals that may modulate SCN neuroglial plasticity through the rhythmic release of serotonin are also reviewed.
