Endogenous Presentation of CD8+ T Cell Epitopes from Epstein-Barr Virus–encoded Nuclear Antigen 1

Epstein-Barr virus (EBV)-encoded nuclear antigen (EBNA)1 is thought to escape cytotoxic T lymphocyte (CTL) recognition through either self-inhibition of synthesis or by blockade of proteasomal degradation by the glycine-alanine repeat (GAr) domain. Here we show that EBNA1 has a remarkably varied cell type-dependent stability. However, these different degradation rates do not correspond to the level of major histocompatibility complex class I-restricted presentation of EBNA1 epitopes. In spite of the highly stable expression of EBNA1 in B cells, CTL epitopes derived from this protein are efficiently processed and presented to CD8(+) T cells. Furthermore, we show that EBV-infected B cells can readily activate EBNA1-specific memory T cell responses from healthy virus carriers. Functional assays revealed that processing of these EBNA1 epitopes is proteasome and transporter associated with antigen processing dependent. We also show that the endogenous presentation of these epitopes is dependent on the newly synthesized protein rather than the long-lived stable EBNA1. Based on these observations, we propose that defective ribosomal products, not the full-length antigen, are the primary source of endogenously processed CD8(+) T cell epitopes front EBNA1.

Utopien, Epiphanien und Melancholie:Der Norden als Erfahrungs- und Imaginationsraum in der deutschsprachigen Gegenwartsliteratur

Die lange zu bemerkende „markante Absenz der nordischen Hemisphäre als literarischer Raum“ (Uwe Schütte) in der deutschsprachigen Nachkriegsliteratur hat in den letzten Jahren ein Ende gefunden. In Texten so unterschiedlicher Autoren wie Sybille Berg, Klaus Böldl, Melitta Breznik, Judith Hermann, Peter Stamm und Antje Ravic Strubel wird vermehrt der (skandinavische) Norden als literarischer Schauplatz in Form eines schriftstellerischen Imaginationsraums utopischer Qualität gestaltet. Allen Texten ist dabei gemein, dass der Norden als bewusst aufgesuchte Peripherie aufgefasst wird, die im Gegensatz zum mitteleuropäischen Zentrum steht. In der postmodernen Welt der Globalisierung, die sich mit Baudrillard als eine die Wirklichkeit usurpierende Simulation begreifen lässt, bietet der Norden den typischerweise mit melancholischen Zügen gezeichneten, an Entfremdung von ihrer Umwelt leidenden Figuren als Ort räumlicher Extremität die zugleich reale und befremdende Erfahrung einer Natur der Extreme, die trotz der zunehmenden Homogenisierung der vernetzten Welt Fortbestand hat und die den auch im Norden anzutreffenden bedeutungsleeren „Nicht-Orten“ (Marc Augé) der modernen Transitgesellschaft ein Erlebnis von Sinnhaftigkeit und Ursprünglichkeit gegenüber stellt. Obwohl (besonders bei Judith Hermann) Zweifel geübt werden an der Zugänglichkeit und emotionalen Wirksamkeit dieser Naturphänomene, besitzen sie dennoch das Potenzial bei den auf der Suche nach ihrer Identität und nach Selbsterfahrung befindlichen Figuren Erlebnisse von Epiphanien auszulösen. Lässt sich in einigen der Texte (besonders bei Peter Stamm) eine Auflösung der geographischen Umgebung ins Unbestimmte bzw. (bei Judith Hermann) eine bewusste Verfremdung skandinavischer Topographie verzeichnen, so werden bei Antje Ravic Strubel gar die Zuschreibungen von Geschlecht und gender vor nördlicher Kulisse aufgebrochen und es entsteht im Norden sowohl ein Freiraum geschlechtlicher Performanz (Judith Butler) als auch ein allgemeiner Projektionsraum für mögliche Lebensentwürfe – und für eine Aufarbeitung der deutschen Geschichte in Skandinavien, die noch deutlicher bei Melitta Breznik anklingt und den Norden auch als Chronotopos und postkolonialen Raum identifiziert. Ausgehend von diesen grundlegenden Merkmalen der Texte geht dieser Beitrag der Frage nach, wie vor dem Hintergrund des viel beschworenen spatial turn neue Perspektiven auf die aktuelle intensive literarische Auseinandersetzung mit dem Norden als konkreter Ort geographischer Realität und als räumliche Metapher mit epistemologischer Aufladung zu gewinnen sind.

Accumulation and fate of mercury in an Everglades aquatic food web

This project examined the pathways of mercury (Hg) bioaccumulation and its relation to trophic position and hydroperiod in the Everglades. I described fish-diet differences across habitats and seasons by analyzing stomach contents of 4,000 fishes of 32 native and introduced species. Major foods included periphyton, detritus/algal conglomerate, small invertebrates, aquatic insects, decapods, and fishes. Florida gar, largemouth bass, pike killifish, and bowfin were at the top of the piscine food web. Using prey volumes, I quantitatively classified the fishes into trophic groups of herbivores, omnivores, and carnivores. Stable-isotope analysis of fishes and invertebrates gave an independent and similar assessment of trophic placement. Trophic patterns were similar to those from tropical communities. I tested for correlations of trophic position and total mercury. Over 4,000 fish, 620 invertebrate, and 46 plant samples were analyzed for mercury with an atomic-fluorescence spectrometer. Mercury varied within and among taxa. Invertebrates ranged from 25–200 ng g −1 ww. Small-bodied fishes varied from 78–>400 ng g −1 ww. Large predatory fishes were highest, reaching a maximum of 1,515 ng−1 ww. Hg concentrations in both fishes and invertebrates were positively correlated with trophic position. I examined the effects of season and hydroperiod on mercury in wild and caged mosquitofish at three pairs of marshes. Nine monthly collections of wild mosquitofish were analyzed. Hydroperiod-within-site significantly affected concentrations but it interacted with sampling period. To control for wild-fish dispersal, and to measure in situ uptake and growth, I placed captive-reared, neonate mosquitofish with mercury levels from 7–14 ng g−1 ww into field cages in the six study marshes in six trials. Uptake rates ranged from 0.25–3.61 ng g−1 ww d −1. As with the wild fish, hydroperiod-within-site was a significant main effect that also interacted with sampling period. Survival exceeded 80%. Growth varied with season and hydroperiod, with greatest growth in short-hydroperiod marshes. The results suggest that dietary bioaccumulation determined mercury levels in Everglades aquatic animals, and that, although hydroperiod affected mercury uptake, its effect varied with season. ^

A preliminary analysis of the correlation of food-web characteristics with hydrology and nutrient gradients in the southern Everglades

We estimated trophic position and carbon source for three consumers (Florida gar, Lepisosteus platyrhincus; eastern mosquitofish, Gambusia holbrooki; and riverine grass shrimp, Palaemonetes paludosus) from 20 sites representing gradients of productivity and hydrological disturbance in the southern Florida Everglades, U.S.A. We characterized gross primary productivity at each site using light/dark bottle incubation and stem density of emergent vascular plants. We also documented nutrient availability as total phosphorus (TP) in floc and periphyton, and the density of small fishes. Hydrological disturbance was characterized as the time since a site was last dried and the average number of days per year the sites were inundated for the previous 10 years. Food-web attributes were estimated in both the wet and dry seasons by analysis of δ15N (trophic position) and δ13C (food-web carbon source) from 702 samples of aquatic consumers. An index of carbon source was derived from a two-member mixing model with Seminole ramshorn snails (Planorbella duryi) as a basal grazing consumer and scuds (amphipods Hyallela azteca) as a basal detritivore. Snails yielded carbon isotopic values similar to green algae and diatoms, while carbon values of scuds were similar to bulk periphyton and floc; carbon isotopic values of cyanobacteria were enriched in C13compared to all consumers examined. A carbon source similar to scuds dominated at all but one study site, and though the relative contribution of scud-like and snail-like carbon sources was variable, there was no evidence that these contributions were a function of abiotic factors or season. Gar consistently displayed the highest estimated trophic position of the consumers studied, with mosquitofish feeding at a slightly lower level, and grass shrimp feeding at the lowest level. Trophic position was not correlated with any nutrient or productivity parameter, but did increase for grass shrimp and mosquitofish as the time following droughts increased. Trophic position of Florida gar was positively correlated with emergent plant stem density.

Atividade antimicrobiana e antioxidante de Licania rigida e Turnera ulmifolia

Introduction: Licania rigida Benth and Turnera ulmifolia Linn. var. elegans are species of semi-arid regional plants used in the treatment of various diseases. Objectives: The purpose of this study was chemically characterize the extracts and fractions and investigate the antimicrobial and antioxidant potential. Methods: For chemical analysis, were performed spectrophotometric quantification of the total phenolic and characterization of the extracts by chromatographic analysis. Evaluation of antioxidant activity was done by determining the radical scavenging capacity DPPH •. Antimicrobial activity was evaluated by agar diffusion, broth microdilutionand time-kill assays. Results: The extracts and fractions L. rigid and T. ulmifolia showed a high phenolic content, the presence of flavonoids, which were determined as chemical markers. It was observed that the extracts of both species performed as sequestering agents in the trial of antioxidant activity in vitro. The L. rigida extract was the only active front strains of S. aureus 33591 (methicillin-resistant), S. aureus 29213, S. epidermidis 12228, and also against the yeast, Candida albicans, Candida dubliniensis, Candida tropicalis, Candida parapsilosis, Candida rugosa, Candida krusei eTrichosporon asahii. Conclusions: Based on these results it is possibly affirm the antioxidant and antimicrobial activity of L. rigida and attributed the presence of polyphenolic flavonoid like responsible.
