Lassa virus activates myeloid dendritic cells but suppresses their ability to stimulate T cells

by Justine Schaeffer, Xavier Carnec, Stéphanie Reynard, Mathieu Mateo, Caroline Picard, Natalia Pietrosemoli, Marie-Agnès Dilliès, Sylvain Baize

Lassa virus (LASV) is responsible for a viral hemorrhagic fever in humans and the death of 3,000 to 5,000 people every year. The immune response to LASV is poorly understood, but type I interferon (IFN-I) and T-cell responses appear to be critical for the host. We studied the response of myeloid dendritic cells (mDC) to (altro…)

Highly competent, non-exhausted CD8+ T cells continue to tightly control pathogen load throughout chronic <i>Trypanosoma cruzi</i> infection

by Angela D. Pack, Matthew H. Collins, Charles S. Rosenberg, Rick L. Tarleton

Trypanosoma cruzi infection is characterized by chronic parasitism of non-lymphoid tissues and is rarely eliminated despite potent adaptive immune responses. This failure to cure has frequently been attributed to a loss or impairment of anti-T. cruzi T cell responses over time, analogous to the T cell dysfunction described for other persistent infections. In this study, we have evaluated the (altro…)

HIV-1 capsids from B27/B57<sup>+</sup> elite controllers escape Mx2 but are targeted by TRIM5α, leading to the induction of an antiviral state

by Natacha Merindol, Mohamed El-Far, Mohamed Sylla, Nasser Masroori, Caroline Dufour, Jia-xin Li, Pearl Cherry, Mélodie B. Plourde, Cécile Tremblay, Lionel Berthoux

Elite controllers (ECs) are a rare subset of HIV-1 slow progressors characterized by prolonged viremia suppression. HLA alleles B27 and B57 promote the cytotoxic T lymphocyte (CTL)-mediated depletion of infected cells in ECs, leading to the emergence of escape mutations in the viral capsid (CA). Whether those mutations modulate CA (altro…)

<i>Arabidopsis</i> class I formins control membrane-originated actin polymerization at pollen tube tips

by Yaxian Lan, Xiaonan Liu, Ying Fu, Shanjin Huang

A population of dynamic apical actin filaments is required for rapid polarized pollen tube growth. However, the cellular mechanisms driving their assembly remain incompletely understood. It was postulated that formin is a major player in nucleating apical actin assembly, but direct genetic and cytological evidence remains to be firmly established. Here we found that both Arabidopsis formin 3 (AtFH3) and formin 5 (AtFH5) (altro…)

A regularity index for dendrites – local statistics of a neuron’s input space

by Laura Anton-Sanchez, Felix Effenberger, Concha Bielza, Pedro Larrañaga, Hermann Cuntz

Neurons collect their inputs from other neurons by sending out arborized dendritic structures. However, the relationship between the shape of dendrites and the precise organization of synaptic inputs in the neural tissue remains unclear. Inputs could be distributed in tight clusters, entirely randomly or else in a regular grid-like manner. Here, we analyze dendritic branching structures using a regularity index R, (altro…)

Functional mechanisms underlie the emergence of a diverse range of plasticity phenomena

by James A. Henderson, Pulin Gong

Diverse plasticity mechanisms are orchestrated to shape the spatiotemporal dynamics underlying brain functions. However, why these plasticity rules emerge and how their dynamics interact with neural activity to give rise to complex neural circuit dynamics remains largely unknown. Here we show that both Hebbian and homeostatic plasticity rules emerge from a functional perspective of neuronal dynamics whereby each neuron learns to encode its own activity in (altro…)

Invasion and effective size of graph-structured populations

by Stefano Giaimo, Jordi Arranz, Arne Traulsen

Population structure can strongly affect evolutionary dynamics. The most general way to describe population structures are graphs. An important observable on evolutionary graphs is the probability that a novel mutation spreads through the entire population. But what drives this spread of a mutation towards fixation? Here, we propose a novel way to understand the forces driving fixation by borrowing techniques from evolutionary demography to quantify (altro…)

Oscillations in working memory and neural binding: A mechanism for multiple memories and their interactions

by Jason E. Pina, Mark Bodner, Bard Ermentrout

Neural oscillations have been recorded and implicated in many different basic brain and cognitive processes. For example, oscillatory neural activity has been suggested to play a role in binding and in the maintenance of information in working memory. With respect to the latter, the majority of work has focused primarily on oscillations in terms of providing a “code” in working memory. However, oscillations may (altro…)

Spore-autonomous fluorescent protein expression identifies meiotic chromosome mis-segregation as the principal cause of hybrid sterility in yeast

by David W. Rogers, Ellen McConnell, Jasmine Ono, Duncan Greig

Genome-wide sequence divergence between populations can cause hybrid sterility through the action of the anti-recombination system, which rejects crossover repair of double strand breaks between nonidentical sequences. Because crossovers are necessary to ensure proper segregation of homologous chromosomes during meiosis, the reduced recombination rate in hybrids can result in high levels of nondisjunction and therefore low gamete viability. Hybrid sterility in interspecific (altro…)
