Full textAlthough the voluntary intake of drugs of abuse is a behavior largely preserved throughout phylogeny, it is currently unclear whether pathological drug use ("addiction") can be observed in species other than humans. Here, we report that behaviors that resemble three of the essential diagnostic criteria for addiction appear over time in rats trained to self-administer cocaine. As in humans, this addiction-like behavior is present only in a small proportion of subjects using cocaine and is highly predictive of relapse after withdrawal. This addiction-like behaviour seems to be associated with a compulsive seeking of the drug but neither with a differential intake of the drug nor with a disinhibited behaviour or a different anxiety level. This addiction-like behaviour is predicted by behavioural factors relative to anxiety and novelty seeking and is associated with transcriptionnal regulations mainly in the prefrontal cortex

Full textLes hormones thyroïdiennes sont essentielles au bon développement du système nerveux central. Ce dernier est très vulnérable à toute déficience en hormones thyroïdiennes, spécialement à la période périnatale précoce où il dépend entièrement du transfert de la part de la mère. Toute réduction du taux d’hormones thyroïdiennes chez la mère ou le retrait précoces du foetus par la naissance prématurée peut avoir d’importants effets néfastes sur la formation du cerveau de la progéniture à court et long terme. Malgré l’état actuel des connaissances concernant l’effet de la carence en hormones thyroïdiennes sur le développement et la fonction du système nerveux central, leur influence sur les circuits nerveux qui régulent le système cardio-respiratoire reste méconnue. Nous proposons que les hormones thyroïdiennes au cours de la période périnatale du rat soient nécessaires au bon développement du réseau neuronal responsable du contrôle cardio-respiratoire. Afin de tester cette hypothèse, nous avons reproduit un modèle d’hypothyroïdisme expérimental par l’exposition de la femelle sur l’entièreté de la gestation à l’agent anti-thyroïdien méthimazole (MMI). L’évaluation des effets sur la commande respiratoire centrale, la ventilation, la réponse à l’hypoxie et l’inhibition cardio-respiratoire par stimulation du chémoréflexe laryngé a été divisée sur différentes tranches d’âge (jours postnataux : P1-P4-P15). Le traitement de MMI réduit le rythme respiratoire produit centralement dans les premiers jours de vie. Un effet âge dépendant du traitement est présent sur la ventilation de l’animal entier et sa réponse à l’hypoxie. L’inhibition cardio-respiratoire est augmentée chez les animaux déficients en hormones thyroïdiennes lors de la stimulation du chémoréflexe laryngé. L’activation importante du système GABAergique est au coeur des conséquences observées. Enfin, nous proposons que les cellules de type «microglie» pourraient moduler le développement du réseau neuronal de contrôle respiratoire en réponse aux hormones thyroïdiennes. En culture cellulaire, ses fonctions sont augmentées par l’exposition à l’hormone T3 et l’effet dépend du micro-environnement. Nous concluons que les hormones thyroïdiennes sont nécessaires pour la mise en place du système nerveux de contrôle respiratoire et autonome.
Thyroid hormones are essential for the normal development of the central nervous system. The latter presents a high vulnerability to any thyroid hormones deficiency, especially in the early stages of perinatal development, when the mother is the only source for the foetus. At that time, any maternal hypothyroidism or premature birth can alter thyroid hormones supply and compromise brain functions on short and long term. Despite the current state of knowledge concerning the effect of thyroid hormone deficiency on the development and function of the central nervous system, their influence on the nervous circuits that regulate the cardiorespiratory system remains unknown. We propose that thyroid hormones during the perinatal period are necessary for the proper development of the neural network responsible for cardiorespiratory control. To test this hypothesis, we reproduced a model of experimental hypothyroidism by exposing the pregnant dams over the entire gestation to the anti-thyroid agent, methimazole (MMI). Effects of the treatment were evaluated on central respiratory command, ventilation, hypoxic response and cardiorespiratory inhibition by laryngeal chemoreflex stimulation, across multiple age groups (P1-P4-P15). MMI treatment reduces the central respiratory rhythm in the first days of life. An age-dependent effect was noted on whole animal ventilation and hypoxic response. Cardiorespiratory inhibition following laryngeal chemoreflex stimulation is increased in thyroid hormones deficient pups. The enhanced GABAergic system activation is a major player in the consequences observed here. Finally, we proposed that microglia could modulate development of the neuronal respiratory control network in response to thyroid hormones. Using cell culture, we demonstrated that their functions are increased by the exposure to T3 and the effect is mediated by the surrounding microenvironment. We conclude that thyroid hormones are necessary for the proper establishment of the respiratory and autonomic nervous control systems.

Full textThe aim of this work was to study emotional behaviours in rats. This was done by comparing control rats with rats that have been stimulated during infancy (i. E. Postnatal handling) according to an ethoexperimental approach. The observation of risk assessment and approach / avoidance behaviours allowed the demonstration that postnatal handling effects are specifically related to a decrease in anxiety-like behaviours, independently from a more general effect on activity level. In addition, we demonstrated that postnatal handling does not modify defensive reactions during a cat confrontation, but have some effects after the confrontation. This result confirms the existence of a predator innate recognition and suggests that the control of defensive reactions is initially under the control of cerebral structures that are not affected by postnatal handling. The discussion of our results is based on the different components of emotional reactivity

Full textAlcohol ingestion during pregnancy may give rise to Foetal Alcohol Syndrome. To better understand the effects of alcohol during brain growth spurt period on physiology and cognitive function, we studied in rats the effects of pre- and postnatal ethanol exposure on 1) the long-term plasticity of the respiratory neuronal network and 2) hippocampus synaptic plasticity involved in learning and memory processes. After perinatal ethanol exposure, long-term respiratory network facilitation (FLT) was reversed to a long-term respiratory depression in 7d old rats, independent on genetic background of the animals. This reversion was mimicked in vitro by a 5-HT2A/2C receptor agonist, the key actors for FLT, while mRNA levels were modified in respiratory areas. In adolescent offspring, ethanol exposure during brain development lead to a facilitation to induce LTD in CA1 hippocampus field studied in vitro which was due to an increase in the response during low frequency conditioning stimulation. This response and the facilitated DLT were NMDA receptor and NR2B subunit dependant but not NR2A subunit dependant. Protein levels for NR1, NR2A and NR2B were all increased in CA1. The late phase of DLT involved both R-GABAA and B without modification in the number of binding sites for R-GABAA. This work shows that in utero alcohol exposure reverses respiratory network plasticity and facilitates synaptic LTD in the hippocampus. These results suggest that in utero alcohol exposure may lead to long-term maladaptation of respiratory function and that effects of alcoholization last until adolescence and alters LTD, the other cellular mechanism of learning and memory beside hippocampus synaptic LTP

Full textThe Masquelet technique is increasingly used for the reconstruction of long bone defects in tumor, sepsis or trauma surgery. It consists of an interposition in the bone defect, of a polymethylmethacrylate (PMMA) spacer around which forms a biological membrane called the “induced-membrane”. Then, autologous fragmented corticocancellous grafts are inserted into the membrane, leading, whatever the length of the defect, to bone healing in a cellular and molecular process which is not elucidated. To further understand and characterize the development of the membrane and its biological activities, we realized the Masquelet technique for bone reconstruction in a smaller animal model: the Sprague-Dawley rat. We describe the experimental development and validation of a critical size femoral defect (8mm) reconstruction in a rat model. The induced membrane from our model shows some mineralization spots and an osteoclastic activity around the PMMA spacer with TRAP (tartrate resistant acid phosphatase) activity, and CTR (calcitonin receptor) and RANK (Receptor activator of Nuclear factor Kappa B) immunostaining. A single cartilage area into the induced membrane was also displayed in contact with the PMMA. This suggests that this reconstruction process may use the osteoclastic remodeling system. This model represents a key step toward the identification of the cellular processes that are involved in remodeling of the grafts and fast healing of long bone defects using Masquelet technique
