Astrocytes and hypothalamic glucose sensing: metabolic role and involvement of astroglial connexins

2012

The hypothalamus plays a pivotal role in the nervous control of glucose homeostasis. This area contains gluco-sensitive neurons. Some of them detect increases in glucose levels and regulate glucose homeostasis by stimulating insulin secretion or inhibiting food intake. It is widely accepted that astrocytes are metabolically coupled to neurons. Lactate, resulting from the metabolism of glucose by astrocytes, is transported via the monocarboxylate transporters (MCTs). In addition, gap junctions (GJ), that form networks within astrocytes, are essential to transfer glucose from the bloodstream to the active neurons. These astroglial GJ mainly consist of connexins 43 and 30 (Cxs).The aims of my …

Communication and Autoinduction in the species Listeria monocytogenes

2014

International audience; In order to withstand changes in their environment, bacteria have evolved mechanisms to sense the surrounding environment, integrate these signals and adapt their physiology to thrive under fluctuating conditions. Among these mechanisms, the ability of bacteria to exchange information between cells has become a dynamic field of interest for microbiologists over the past four decades. First described by Nelson et al.,1 this phenomenon often referred as either cell-cell communication, Quorum Sensing and/or AutoInduction involves the synthesis of small signal molecules called autoinducers. These signal molecules may be sensed by the bacterial population in the vicinity …

2010

Communication orale, résumé; Parmi les mécanismes cellulaires qui participent à la mise en place des biofilms, l’échange de molécules de communication apparaît nécessaire chez de nombreux microorganismes. Listeria monocytogenes est une bactérie ubiquiste responsable de pathologies sévères chez des populations à risque (immunodéprimés, femmes enceintes, personnes âgées) en cas de consommation d’aliments contaminés. Nous avons récemment démontré que le système de communication agr est impliqué au cours de la croissance sessile de cette bactérie (Rieu et al., 2007). Par ailleurs, l’expression du système agr était hétérogène pendant la croissance en biofilm (Rieu et al., 2008) et localisée à sa…

Cartographie de la diversité des sols viticoles de versant par imagerie à haute résolution : contribution à la connaissance des terroirs

2014

The Burgundian vineyard hillslopes (Côte-d’Or, France) exhibit a high diversity of soils resulting from the combination of several natural and anthropogenic factors acting at various spatio-temporal scales. The soil types have major role in viticulture, since they partly determine wine-growing quality. However, soil undergoes important degradation caused by hydric erosion and vineyard management practices. To control this soil heritage for a sustained viticulture in Côte-d’Or, a better knowledge of soil is necessary. The objectives of this work is to characterise vineyard soils and to identify the factors governing their diversity using an interdisciplinary approach crossing geology, geomor…

Complémentarité des données de télédétection pour l'analyse des transformations de l'occupation du sol dans des zones humides urbaines. Application a…

2008

International audience; Dans le cadre d'un programme ECOS-Nord, notre étude analyse les transformations récentes de l'occupation du sol sur deux zones humides urbaines : les hortillonnages d'Amiens et les chinampas de Mexico. Malgré des contextes différents, ces deux espaces sont les supports d'usages et de dynamiques très similaires : des techniques identiques d'agriculture sur l'eau et un déclin de l'activité agricole au XXe siècle au profit de celle des loisirs. L'objectif est double : identifier et quantifier les changements sur chacun des sites, puis les confronter de façon à mettre en évidence les points communs et les spécificités locales, tant dans la nature des changements, que dan…
