Résumé : International audience
Plants often rely on external, mutualistic partners to survive and reproduce in resource-limited environments or for protection from enemies. Such interactions, including mycorrhizal symbioses and ant-plant associations, are widespread and play an important role at the ecosystem and community levels. In ant-plant mutualisms, the plants may benefit from both the protection provided by the presence of ants and from the nutrients absorbed from insect debris. However, the role of third partners in plant nutrition, particularly ant-associated fungi, has never before been demonstrated. 2. We investigate this issue in the ant-plant Hirtella physophora. In this model system, Allomerus decemarticulatus ants are involved in two, highly specific interactions: first, with their host plant, and, secondly, with a fungus that they actively manipulate. Moreover, the ants combine both plant trichomes and fungal hyphae to make a trap to capture prey. 3. We empirically demonstrate the existence of a third type of interaction between the fungus and the plant through the use of both experimental enrichments with stable isotopes (15N) and histological approaches. The fungus growing in the galleries plays a role in providing nutrients to the host plant, in addition to the structural role it plays for the ants. Fungus-facilitated nitrogen uptake occurs mainly in old domatia, where abundant hyphae are in close contact with the plant cells. Whether the fungi inside the domatia and those in the galleries are the same is still uncertain. 4. Synthesis. Together, our results show that a fungal partner in an ant-plant mutualism can benefit the plant by improving its nutrient uptake, and they demonstrate the existence of a true tripartite mutualismin this system. Our results add further evidence to the notion that interpretations of some ant-plant symbioses as purely protective mutualisms have overlooked these nutritional aspects.

Résumé : International audience
Few studies have been undertaken to assess the possible effects of bisphenol A (BPA) on the reproductive hormone balance in animals or humans with often contradictory results. We investigated possible direct endocrine disruption by BPA of the fetal testes of 2 rat strains (14.5-17.5 days post-coitum) and humans (8-12 gestational weeks) and under different culture conditions. BPA concentrations of 10-8M and 10-5M for 72h reduced testosterone production by the Sprague-Dawley fetal rat testes, while only 10-5M suppressed it in the Wistar strain. The suppressive effects at 10-5M were seen as early as 24h and 48h in both strains. BPA at 10-7-10-5M for 72h suppressed the levels of fetal rat Leydig cell insulin-like factor 3 (INSL3). BPA exposure at 10-8M, 10-7M, and 10-5M for 72h inhibited testosterone production in fetal human testes. For the lowest doses, the effects observed occurred only when no gonadotrophin was added to the culture media and were associated with a poorly preserved testicular morphology. We concluded that (i) BPA can display anti-androgenic effects both in rat and human fetal testes; (ii) it is essential to ascertain that the divergent effects of endocrine disruptors between species in vitro do not result from the culture conditions used, and/or the rodent strain selected; (iii) the optimization of each in vitro assay for a given species should be a major objective rather than the search of an hypothetical trans-species consensual model-system, as the organization of the testis is intrinsically different between mammalian species; (iv) due to the uncertainty existing on the internal exposure of the human fetal testis to BPA, and the insufficient number of epidemiological studies on the endocrine disruptive effects of BPA, caution should be taken in the extrapolation of our present results to the human reproductive health after fetal exposure to BPA.

Résumé : International audience
Benzo[a]pyrene (B[a]P), the prototype molecule of polycyclic aromatic hydrocarbons, exhibits genotoxic and carcinogenic effects, which has led the International Agency for Research on Cancer to recognize it as a human carcinogen. Besides the well-known apoptotic signals triggered by B[a]P, survival signals have also been suggested to occur, both signals likely involved in cancer promotion. Our previous work showed that B[a]P induced an hyperpolarization of mitochondrial membrane potential (ΔΨm) in rat hepatic epithelial F258 cells. Elevated ΔΨm plays a role in tumor development and progression, and nitric oxide (NO) has been suggested to be responsible for increases in ΔΨm. The present study therefore aimed at evaluating the impact of B[a]P on NO level in F258 cells, and at testing the putative role for NO as a survival signal, notably in link with ΔΨm. Our data demonstrated that B[a]P exposure resulted in an NO production which was dependent upon the activation of the inducible NO synthase. This enzyme activation involved AhR and possibly p53 activation. Preventing NO production not only increased B[a]P-induced cell death but also blocked mitochondrial hyperpolarization. This therefore points to a role for NO as a survival signal upon B[a]P exposure, possibly targeting ΔΨm

Résumé : International audience
Les plages sableuses constituent une frontière mobile et poreuse entre l'océan ouvert et la terre. La compréhension de la circulation dans les nappes de plage est importante pour une variété de processus physiques, biologiques et chimiques. On cherche à caractériser in-situ la dynamique souterraine sous la zone de swash. Le site atelier est la plage microtidale de Rousty (Camargue, France). L'étude, réalisée sur 48h les 13 et 14 décembre 2014, fait partie d'une plus grande campagne de mesure visant à caractériser la réponse hydro-morphologique de la plage de Rousty à une saison hivernale. La période présentée ici correspond à la phase de déclin d'une tempête modérée. La stratégie retenue dans le cadre de ce projet a été de déployer un réseau de15 capteurs de pression enterrés sous la zone de swash. Les caractéristiques des vagues incidentes, à la fois au large et dans la zone de surf interne, ont été mesurées conjointement à l'utilisation d'un LiDAR terrestre haute fréquence permettant de suivre la surface libre et l'évolution du lit sableux à haute fréquence sur la zone de swash. L'analyse des données moyennées dans le temps a mis en évidence la présence d'un schéma de circulation relativement robuste sous la zone de swash, qui se décale vers le large en suivant la descente du niveau moyen et la diminution de l'activité des vagues. La tendancedominante est un écoulement vers le large, avec une intensité maximale de l'ordre de 0.1mm/s modulé par des infiltrations et exfiltrations dans les parties hautes et basses de la zone de swash, respectivement. L'analyse haute fréquence à des événements de swash sélectionnés ont mis en évidence uncycle souterrain caractéristique.

Résumé : International audience
This study examined whether the antidermatophytic activity of essential oils (EOs) can be used as an indicator for the discovery of active natural products against Leishmania amazonensis. The aerial parts of seven plants were hydro-distilled. Using broth microdilution techniques, the obtained EOs were tested against three strains of dermatophytes (Trichophyton mentagrophytes, Microsporum gypseum and Microsporum canis). To compare the EOs antifungal and antiparasitic effects, the EOs activities against axenic amastigotes of L. amazonensis were concurrently evaluated. For the most promising EOs, their antileishmanial activities against parasites infecting peritoneal macrophages of BALB/c mice were measured. The most interesting antifungal candidates were the EOs from Cymbopogon citratus, Otacanthus azureus and Protium heptaphyllum, whereas O. azureus, Piper hispidum and P. heptaphyllum EOs exhibited the lowest 50% inhibitory concentration (IC 50) values against axenic amastigotes, thus revealing a certain correspondence between both activities. The P. hispidum EO was identified as the most promising product in the results from the infected macrophages model (IC 50 : 4.7 µg/mL, safety index: 8). The most abundant compounds found in this EO were sesquiter-penes, notably curzerene and furanodiene. Eventually, the evaluation of the antidermatophytic activity of EOs appears to be an efficient method for identifying new potential drugs for the treatment of L. amazonensis.

Résumé : International audience
Holocene Lake Mega-Chad (LMC) was the largest late Quaternary water-body in Africa. The development of this giant paleo-lake is related to a northward shift of the isohyetes interpreted as evidence for an enhanced Monsoon (African Humid Period). Numerous preserved coastal features have been described all around the LMC shore. Such features reveal the main paleo-hydrodynamical tendencies. In the context of a closed water-body like LMC, hydrodynamics are forced mainly by winds. We use a three-dimensional numerical model (SYMPHONIE) to simulate the mean hydrodynamics in LMC under both Harmattan-like (northeasterly trade winds) and Monsoon-like (southwesterly winds) forcings. The northern part of LMC displays coastal features, such as sand spits, that are consistent with the simulations forced by Harmattan-like winds. Geomorphic features related to Monsoon-driven hydrodynamics are not clearly expressed. They could have developed during the early stage of LMC but subsequently reworked. At the time of sand-spit building, Harmattan-like driven hydrodynamics prevailed and related coastal features were preferentially preserved in the sedimentary record.

Résumé : International audience
The southernmost part of the Ryukyu subduction, where the Philippine Sea Plate is subducting under the Eurasian Plate, is known to be a very seismically active region of transition from a north-dipping subduction along the Ryukyu subduction to an ~ SE-NW collision along the Taiwanese orogenic wedge. In this paper, we will focus on the Ryukyu forearc area close to Taiwan where the deformation is paroxysmal. In order to decipher the nature of the seismic deformation in this region, a three month passive experiment, combining 22 Ocean Bottom Seismometers and 51 onland stations, has been led. Starting from an a-priori heterogeneous model, we have obtained 801 well-located earthquake hypocenters, a precise P-wave tomography model and 14 focal mechanisms. The seismicity along the Ryukyu forearc is mainly located not only in the vicinity of the Interplate Seismogenic Zone (ISZ) but also within both the subducting PSP and the overriding plate. Seismicity within the upper-plate is essentially localized east of Nanao basin where NW-SE extension occurs, and northwest of the Hoping basin where strike-slip dominates. As revealed by both the P-wave velocity structure and the newly derived seismicity, we argue that a sub-vertical step offsetting the subducting PSP around 10 km may support the presence of a trench-parallel tear. The PSP also undergoes extension in its upper part that is probably caused by buckling and slab pull. The P-wave velocity structure reveals three other major features: (1) a continuity between the Central Range and the Ryukyu Arc with a shallower Moho (~ 30 km depth) between ~ 122.3°N and ~ 122.5°N along the Ryukyu Arc, (2) high P-wave velocities along the eastern side of the Central Range and, (3) two bodies with similar high crustal velocities (6.5-7.0 km/s) at 12-18 km depths, embedded within the Ryukyu arc basement, just north of Hoping Basin and north of the Nanao Basin.

Résumé : International audience
We provide new constraints on the modes of mantle exhumation and denudation in the pre-orogenic Pyrenees by investigating the poorly known peridotites located east of the Lherz body, in eastern Ariè ge (Vicdessos, Urs, Bestiac, Caussou and Prades main peridotitic bodies). We show that: (1) numerous peridotite bodies, not described so far, are constituted by decametric to sub-metric outcrops scattered between and around the main outcrops identified by Monchoux (1970); (2) most of the peridotites form blocks and lenses of various sizes, from millimetric monocrystalline grains to hectometric olistoliths, embedded in debris flows involving mainly Mesozoic metasediments; these peridotites can therefore be linked to the S-type peridotites of Lagabrielle et al. (2010), and share similarities with the peridotites of Lherz region (Clerc et al., 2012). All originated from tectono-sedimentary processes associated with mantle exhumation in relation with extreme thinning and breakoff of the continental basement; (3) the various petrographic characters of these peridotites and their heterogeneity in serpentinisation degree imply a peculiar mode of exhumation, which merges mantle fragments inherited from different structural levels; (4) the lack of tectonic structures such as faults and shear planes associated with the ultramafic-rich breccia formation and the presence of neoformation of metamorphic minerals within the matrix preclude their origin as cataclasites related to the Latest Cretaceous and Tertiary Pyrenean contractional deformation. The peridotites of eastern Ariè ge are indisputable witnesses of the presence of an inverted hyper-extended Cretaceous passive margin forming the current North Pyrenean zone. The geometry of the extensional system was complex and probably associated with strike-slip faults and transcurrent motion. ß 2016 The Authors.

Résumé : International audience
The IL-33/ST2 axis plays a protective role in T-cell-mediated hepatitis, but little is known about the functional impact of endogenous IL-33 on liver immunopathology. We used IL-33-deficient mice to investigate the functional effect of endogenous IL-33 in concanavalin A (Con A)-hepatitis. IL-33(-/-) mice displayed more severe Con A liver injury than wild-type (WT) mice, consistent with a hepatoprotective effect of IL-33. The more severe hepatic injury in IL-33(-/-) mice was associated with significantly higher levels of TNF-alpha and IL-1 beta and a larger number of NK cells infiltrating the liver. The expression of Th2 cytokines (IL-4, IL-10) and IL-17 was not significantly varied between WT and IL-33(-/-) mice following Con A-hepatitis. The percentage of CD25(+) NK cells was significantly higher in the livers of IL-33(-/-) mice than in WT mice in association with upregulated expression of CXCR3 in the liver. Regulatory T cells (Treg cells) strongly infiltrated the liver in both WT and IL-33(-/-) mice, but Con A treatment increased their membrane expression of ST2 and CD25 only in WT mice. In vitro, IL-33 had a significant survival effect, increasing the total number of splenocytes, including B cells, CD4(+) and CD8(+) T cells, and the frequency of ST2(+) Treg cells. In conclusion, IL-33 acts as a potent immune modulator protecting the liver through activation of ST2(+) Treg cells and control of NK cells.

ObjectivesTo compare the efficacy, in current clinical practice, of ă first regimens containing abacavir with lamivudine (ABC/3TC) or ă tenofovir with emtricitabine (TDF/FTC) in patients with baseline viral ă load 100000 HIV-1 RNA copies/mL. ă MethodsUsing a prospective cohort, we selected all patients starting a ă first HIV regimen based either on ABC/3TC or on TDF/FTC. The propensity ă score (PS) method was used to limit the indication bias due to the ă observational nature of the data. Adjusting and weighting methods via PS ă were used to compare the effectiveness of a first regimen containing ă ABC/3TC or TDF/FTC. The primary outcome was treatment failure by month ă 12 (M12). ă ResultsOverall, 2781 patients started an antiretroviral (ARV) regimen ă with ABC/3TC or TDF/FTC each in combination with efavirenz, boosted ă atazanavir or boosted darunavir. Among the 2472 uncensored patients ă before M12, 962 (39%) had a baseline viral load 100000 copies/mL of ă whom 294 were in treatment failure at or before M12. Our analyses showed ă no difference between ABC/3TC and TDF/FTC in the risk of treatment ă failure at M12 in patients starting an ARV regimen with a high viral ă load (100000 copies/mL). ă ConclusionsUsing a large prospectively collected cohort of patients ă seeking care in France, we found no evidence that ABC/3TC based regimens ă led to more failures than TDF/FTC based ones in patients with high ă baseline viral loads.

Résumé : International audience
Based on both experimental and clinical data, tamoxifen has been proposed to have cardiovascular benefits, although the mechanism(s) contributing to that protective effect are still poorly understood. In vitro experiments demonstrated that tamoxifen elicits its transcriptional effect through estrogen receptor (ER) α, but other targets can participate in its actions. However, although tamoxifen selectively activates the activating function (AF)-1 of ERα, we recently showed that this ERα subfunction is dispensable for the atheroprotective action of 17β-estradiol (E2), the main ligand of ERs. The goal of the present work is to determine to which extent ERα and its AF-1 mediate the vasculoprotective action of tamoxifen. Our data confirm that tamoxifen exerts an atheroprotective action on low density lipoprotein receptor (LDL-r(-/-)) female mice, but, in contrast to E2, it fails to accelerate reendothelialization after carotid electric injury. Tamoxifen and E2 elicit differences in gene expression profiles in the mouse aorta. Finally, the atheroprotective action of tamoxifen is abrogated in ERα(-/-)LDL-r(-/-) mice and in LDL-r(-/-) mice selectively deficient in ERαAF-1 (ERαAF-1(0/0)LDL-r(-/-)). Our results demonstrate, for the first time to our knowledge, that tamoxifen mediates its actions in vivo through the selective activation of ERαAF-1, which is sufficient to prevent atheroma, but not to accelerate endothelial healing.

Résumé : International audience
Estrogen receptor alpha (ERα) has been recognized now for several decades as playing a key role in reproduction and exerting functions in numerous nonreproductive tissues. In this review, we attempt to summarize the in vitro studies that are the basis of our current understanding of the mechanisms of action of ERα as a nuclear receptor and the key roles played by its two activation functions (AFs) in its transcriptional activities. We then depict the consequences of the selective inactivation of these AFs in mouse models, focusing on the prominent roles played by ERα in the reproductive tract and in the vascular system. Evidence has accumulated over the two last decades that ERα is also associated with the plasma membrane and activates non-nuclear signaling from this site. These rapid/nongenomic/membrane-initiated steroid signals (MISS) have been characterized in a variety of cell lines, and in particular in endothelial cells. The development of selective pharmacological tools that specifically activate MISS and the generation of mice expressing an ERα protein impeded for membrane localization have begun to unravel the physiological role of MISS in vivo. Finally, we discuss novel perspectives for the design of tissue-selective ER modulators based on the integration of the physiological and pathophysiological roles of MISS actions of estrogens.
