Parasite Proximity Drives the Expansion of Regulatory T Cells in Peyer's Patches following Intestinal Helminth Infection

Nicola Harris, Mario Michael Zaiss, Beatrice Volpe, Julia Esser-von Bieren, Ilaria Mosconi, Lalit Kumar Dubey, Luc Xavier Marie Lebon

Helminth infections are typically chronic in nature; however, the exact molecular mechanisms by which these parasites promote or thwart host immunity remain unclear. Worm expulsion requires the differentiation of CD4(+) T cells into Th2 cells, while regula ...

Evolution of division of labor in artificial societies

Pawel Lichocki

Natural and artificial societies often divide the workload between specialized members. For example, an ant worker may preferentially perform one of many tasks such as brood rearing, foraging and nest maintenance. A robot from a rescue team may specialize ...

Arbuscular mycorrhizal fungi reduce the differences in competitiveness between dominant and subordinate plant species

Alexandre Buttler, Pierre Rémi Mariotte, Thomas Spiegelberger, Aurélie Thébault, Claire Meugnier

In grassland communities, plants can be classified as dominants or subordinates according to their relative abundances, but the factors controlling such distributions remain unclear. Here, we test whether the presence of the arbuscular mycorrhizal (AM) fun ...

IL-1β Suppresses Innate IL-25 and IL-33 Production and Maintains Helminth Chronicity

Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Ilaria Mosconi, Nadine Guenat

Approximately 2 billion people currently suffer from intestinal helminth infections, which are typically chronic in nature and result in growth retardation, vitamin A deficiency, anemia and poor cognitive function. Such chronicity results from co-evolution ...

Limitations of response thresholds models of division of labor

Dario Floreano, Laurent Keller, Pawel Lichocki

High levels of cooperation are often cited as the primary reasons for the ecological success of social insects. In social insects, workers perform a multitude of tasks such as foraging, nest construction and brood rearing without central control of how wor ...

Loss of reproductive parasitism following transfer of male-killing Wolbachia to Drosophila melanogaster and Drosophila simulans

Wolbachia manipulate insect host biology through a variety of means that result in increased production of infected females, enhancing its own transmission. A Wolbachia strain (wInn) naturally infecting Drosophila innubila induces male killing, while nativ ...

Neural networks as mechanisms to regulate division of labor

Dario Floreano, Laurent Keller, Pawel Lichocki

In social insects, workers perform a multitude of tasks such as foraging, nest construction and brood rearing without central control of how work is allocated among individuals. It has been suggested that workers choose a task by responding to stimuli gath ...

Redundant Notch1 and Notch2 Signaling Is Necessary for IFNγ Secretion by T Helper 1 Cells During Infection with Leishmania major

Freddy Radtke, Ute Koch, Floriane Auderset

The protective immune response to intracellular parasites involves in most cases the differentiation of IFNγ-secreting CD4(+) T helper (Th) 1 cells. Notch receptors regulate cell differentiation during development but their implication in the polarization ...

An essential Aurora-related kinase transiently associates with spindle pole bodies during Plasmodium falciparum erythrocytic schizogony

Aurora kinases compose a family of conserved Ser/Thr protein kinases playing essential roles in eukaryotic cell division. To date, Aurora homologues remain uncharacterized in the protozoan phylum Apicomplexa. In malaria parasites, the characterization of A ...

Vaccination of mice with chitosan nanogel-associated recombinant NcPDI against challenge infection with Neospora caninum tachyzoites

Peter Käuper, Nicola Rossi

P>The effects of nanogel encapsulation of recombinant NcPDI (recNcPDI) following vaccination of mice by intranasal or intraperitoneal routes and challenge infection with Neospora caninum tachyzoites were investigated. Nanogels were chitosan based, with an ...
