NCoR1 restrains thymic negative selection by repressing Bim expression to spare thymocytes undergoing positive selection

Johan Auwerx, Shuo Zhang, Na Zhang, Hui Xiao, Ye Zheng

Thymocytes must pass both positive and negative selections to become mature T cells. Negative selection purges thymocytes whose T-cell receptors (TCR) exhibit high affinity to self-peptide MHC complexes (self pMHC) to avoid autoimmune diseases, while posit ...

Form - function relationships in dragonfly mandibles under an evolutionary perspective

Alessandra Patera

Functional requirements may constrain phenotypic diversification or foster it. For insect mouthparts, the quantification of the relationship between shape and function in an evolutionary framework remained largely unexplored. Here, the question of a functi ...

Chromosomal contacts connect loci associated with autism, BMI and head circumference phenotypes

Bart Deplancke, Marion Leleu, Nele Gheldof, Loyse Hippolyte

Copy number variants (CNVs) are major contributors to genomic imbalance disorders. Phenotyping of 137 unrelated deletion and reciprocal duplication carriers of the distal 16p11.2 220 kb BP2-BP3 interval showed that these rearrangements are associated with ...

The corepressor NCOR1 regulates the survival of single-positive thymocytes

Johan Auwerx

Nuclear receptor corepressor 1 (NCOR1) is a transcriptional regulator bridging repressive chromatin modifying enzymes with transcription factors. NCOR1 regulates many biological processes, however its role in T cells is not known. Here we show that Cd4-Cre ...

Toward the identification of cellular mechanisms behind the lethal phenotypes in Plasmodium berghei blood stages with PlasmoGEM and metabolic modeling

Vassily Hatzimanikatis

Recent advances in cell genome editing techniques enable the generation of high-throughput gene knockout data in the malaria parasites in vivo. Integrative analysis of this data can lead to the identification of biological mechanisms that explain the obser ...

Annual glare evaluation for fabrics

Marilyne Andersen, Jan Wienold

Although fabrics are widely used as shading devices, reliable simulation models are rather rare and therefore the choice of a fabric with appropriate material characteristics is difficult. This paper presents a simulation model, which can be applied to mos ...

Bypassing bacterial infection in phage display by sequencing DNA released from phage particles

Christian Heinis, Xudong Kong, Camille Villequey

Phage display relies on a bacterial infection step in which the phage particles are replicated to perform multiple affinity selection rounds and to enable the identification of isolated clones by DNA sequencing. While this process is efficient for wild-typ ...

An Approximate Markov Model for the Wright-Fisher Diffusion and Its Application to Time Series Data

Jeffrey David Jensen, Anna Ferrer Admetlla

The joint and accurate inference of selection and demography from genetic data is considered a particularly challenging question in population genetics, since both process may lead to very similar patterns of genetic diversity. However, additional informat ...

The Impact of Linked Selection in Chimpanzees: A Comparative Study

Jeffrey David Jensen, Susanne Petra Pfeifer

Levels of nucleotide diversity vary greatly across the genomes of most species owing to multiple factors. These include variation in the underlying mutation rates, as well as the effects of both direct and linked selection. Fundamental to interpreting the ...
