Family Kungalariidae, n. fam., new Mesozoic entactinarian Radiolaria with a nassellarian-type initial spicule

Based on internal structure, a new family of entactinarian radiolarians, the Kungalariidae, is described with three new genera and four species: Kungalaria newcombi, Cachecreekaria californiensis, Transylvanaria devaensis, and T. hattorii. Members of this family have an eccentric internal, nassellarian-type initial spicule with bar MB, rays A, V, L, I, and spine Ax; a medullary shell built above the plane of lateral rays as in the cephalis of many nassellarians; and a spherical to subspherical cortical shell around the medullary shell. This new family is part of a group of Triassic entactinarians structurally intermediate between Entactinaria, or spicule-bearing Spumellaria, and Nassellaria. The new genera and species described occur in the Rhaetian of Queen Charlotte Islands, British Columbia, Aalenian to early-mid Bajocian of central Japan, Cenomanian of California, and Coniacian of Romania.

An evaluation of new parsimony-based versus parametric inference methods in biogeography: a case study using the globally distributed plant family Sapindaceae

Aim  Recently developed parametric methods in historical biogeography allow researchers to integrate temporal and palaeogeographical information into the reconstruction of biogeographical scenarios, thus overcoming a known bias of parsimony-based approaches. Here, we compare a parametric method, dispersal-extinction-cladogenesis (DEC), against a parsimony-based method, dispersal-vicariance analysis (DIVA), which does not incorporate branch lengths but accounts for phylogenetic uncertainty through a Bayesian empirical approach (Bayes-DIVA). We analyse the benefits and limitations of each method using the cosmopolitan plant family Sapindaceae as a case study.Location  World-wide.Methods  Phylogenetic relationships were estimated by Bayesian inference on a large dataset representing generic diversity within Sapindaceae. Lineage divergence times were estimated by penalized likelihood over a sample of trees from the posterior distribution of the phylogeny to account for dating uncertainty in biogeographical reconstructions. We compared biogeographical scenarios between Bayes-DIVA and two different DEC models: one with no geological constraints and another that employed a stratified palaeogeographical model in which dispersal rates were scaled according to area connectivity across four time slices, reflecting the changing continental configuration over the last 110 million years.Results  Despite differences in the underlying biogeographical model, Bayes-DIVA and DEC inferred similar biogeographical scenarios. The main differences were: (1) in the timing of dispersal events - which in Bayes-DIVA sometimes conflicts with palaeogeographical information, and (2) in the lower frequency of terminal dispersal events inferred by DEC. Uncertainty in divergence time estimations influenced both the inference of ancestral ranges and the decisiveness with which an area can be assigned to a node.Main conclusions  By considering lineage divergence times, the DEC method gives more accurate reconstructions that are in agreement with palaeogeographical evidence. In contrast, Bayes-DIVA showed the highest decisiveness in unequivocally reconstructing ancestral ranges, probably reflecting its ability to integrate phylogenetic uncertainty. Care should be taken in defining the palaeogeographical model in DEC because of the possibility of overestimating the frequency of extinction events, or of inferring ancestral ranges that are outside the extant species ranges, owing to dispersal constraints enforced by the model. The wide-spanning spatial and temporal model proposed here could prove useful for testing large-scale biogeographical patterns in plants.

Implication of TNF family members in the immune response to the infection with the intracellular protozoan parasite "Leishmania major"

Suite à une infection avec le protozoaire Leishmania major (L. major), les souris sensibles de souche BALB/c développent des lésions progressives associées à une maturation des cellules CD4+ TH2 sécrétant de l'IL-4. A l'inverse, les souris résistantes de souche C57BL/6 guérissent à terme, sous l'influence de l'expansion des cellules CD4+ TH1 produisant de l'IFNy qui a un effet synergique avec le TNF ("tumor necrosis factor") sur l'activation des macrophages et leur fonction leishmanicide. Lors de notre étude nous avons montré que des souris C57BL/6 doublement déficientes en TNF et FasL ("Fas ligand") infectées par L. major ne guérissaient ni leur lésions ni ne contrôlaient la réplication de parasites malgré une réponse de type TH1. Bien que l'activité de synthétase inductible de l'oxyde nitrique ("iNOs") soit comparable chez les souris doublement ou simplement déficientes, seules celles déficientes en FasL ont démontré une incapacité à contrôler la réplication parasitaire. De surcroît il est apparu que le FasL a un effet synergique avec l'IFNy. L'adjonction de FasL à une culture cellulaire de macrophages stimulés par l'IFNy conduit à une activation de ces cellules. Celle-ci est démontrée par l'augmentation de la production de TNF et de NO par les macrophages ainsi que par l'élimination des parasites intracellulaires par ces mêmes cellules. Alors que le FasL et l'IFNy semblent essentiels au contrôle de la réplication des pathogènes intracellulaires, la contribution de TNF s'oriente davantage vers le contrôle de l'inflammation. L'activation macrophagique via Fas précède la mort cellulaire qui survient quelques jours plus tard. Cette mort cellulaire programmée était indépendante de la cascade enzymatique des caspases, au vu de l'absence d'effet de l'inhibiteur non-spécifique ZVAD-fmk des caspases. Ces résultats suggèrent que l'interaction Fas-FasL agit comme une costimulation nécessaire à une activation efficace des macrophages, la mort cellulaire survenant consécutivement à l'activation des macrophages.¦-¦Upon infection with the protozoan parasite Leishmania major (L. major), susceptible BALB/c mice develop non healing lesions associated with the maturation of CD4+ TH2 cells secreting IL-4. In contrast, resistant C57BL/6 mice are able to heal their lesions, because of CD4+ TH1 cell expansion and production of high levels of IFNy, which synergizes with tumour necrosis factor (TNF) in activating macrophages to their microbicidal state. In our study we showed that C57BL/6 mice lacking both TNF and Fas ligand (FasL) infected with L. major neither resolved their lesions nor controlled L. major replication despite a strong TH1 response. Although comparable inducible nitric oxide synthase (iNOs) was measured in single or double deficient mice, only mice deficient in FasL failed to control the parasite replication. Moreover FasL synergized with IFNy for the induction of leishmanicidal activity within macrophages infected with L. major in vitro. Addition of FasL to IFNy stimulated macrophages led to their activation, as reflected by the secretion of tumour necrosis factor and nitrite oxide, as well as the induction of their microbicidal activity, resulting in the killing of intracellular L. major. While FasL along with IFNy and iNOs appeared to be essential for the complete control of intracellular pathogen replication, the contribution of TNF appeared more important in controlling the inflammation on the site of infection. Macrophage activation via Fas pathway preceded cell death, which occurred a few days after Fas mediated activation. This program cell death was independent of caspase enzymatic activities as revealed by the lack of effect of ZVAD-fmk, a pan-caspase inhibitor. These results suggested that the Fas-FasL pathway, as part of the classical activation pathway of the macrophages, is essential in the stimulation of macrophage leading to a microbicidal state and to AICD, and may thus contribute to the pathogenesis of L. major infection.

The TPTE gene family: cellular expression, subcellular localization and alternative splicing.

The human TPTE (Transmembrane Phosphatase with TEnsin homology) gene family encodes a PTEN-related tyrosine phosphatase with four potential transmembrane domains. Chromosomal mapping revealed multiple copies of the TPTE gene on chromosomes 13, 15, 21, 22 and Y. Human chromosomes 13 and 21 copies encode two functional proteins, TPIP (TPTE and PTEN homologous Inositol lipid Phosphatase) and TPTE, respectively, whereas only one copy of the gene exists in the mouse genome. In the present study, we show that TPTE and TPIP proteins are expressed in secondary spermatocytes and/or prespermatids. In addition, we report the existence of several novel alternatively spliced isoforms of these two proteins with variable number of transmembrane domains. The latter has no influence on the subcellular localization of these different peptides as shown by co-immunofluorescence experiments. Finally, we identify another expressed TPTE copy, mapping to human chromosome 22, whose transcription appears to be under the control of the LTR of human endogenous retrovirus RTVL-H3.

Impact of family structure on long-term survivors of osteosarcoma

Rapport de synthèse : But du travail : le pronostic des patients atteints d'ostéosarcome s'est considérablement amélioré grâce à l'utilisation de thérapies combinées performantes. Cependant, ces traitements agressifs sont grevés de complications chroniques. Notre travail a consisté à l'évaluation du status fonctionnel, psychologique et familial chez des patients survivants au long cours d'ostéosarcome traités au centre pluridisciplinaire d'oncologie. Patients et méthodes: 15 survivants au long cours d'ostéosarcome ont été évalués à la recherche de séquelles physiques et psychologiques. Pour l'évaluation fonctionnelle, nous avons utilisé la méthode de Enneking. L'évaluation psychologique a été basée sur un test d'évaluation globale (GHQ-28), sur un test de cohésion familiale (FAST test) et sur une échelle d'évaluation de symptômes post-traumatiques. Résultats: sur le plan fonctionnel, seuls 5 patients présentaient des séquelles graves et 10 des handicaps modérés. 4 patients souffraient de symptômes dépressifs. 6 patients ont décrit uns structure familiale déséquilibrée dont 3 des 4 patients avec des symptômes dépressifs, les 4 patients avec symptômes post-traumatiques et 5 des 7 patients avec une mauvaise acceptation émotionnelle. Conclusions: la plupart des patients souffrant d'ostéosarcome présentent une bonne récupération fonctionnelle. Seule une minorité reste sévèrement handicapée. Un tiers des patients souffre de symptômes dépressifs et de stress post-traumatique. Une mauvaise acceptation émotionnelle est fortement liée à une structure familiale déséquilibrée. La situation psychologique et familiale des patients atteints d'ostéosarcome doit donc être rapidement prise en compte afin d'améliorer leur évolution au long cours.
