Experimental increase of worker diversity benefits brood production in ants
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Enzyme-assisted high throughput sequencing of an expanded genetic alphabet at single base resolution
With just four building blocks, low sequence information density, few functional groups, poor control over folding, and difficulties in forming compact folds, natural DNA and RNA have been disappointing platforms from which to evolve receptors, ligands ...

The SoftWipe tool and benchmark for assessing coding standards adherence of scientific software
Scientific software from all areas of scientific research is pivotal to obtaining novel insights. Yet the coding standards adherence of scientific software is rarely assessed, even though it might lead to incorrect scientific results in the worst case ...

Though all theories for the origin of life require a source of energy to promote primordial chemical reactions, the nature of energy that drove the emergence of metabolism at origins is still debated. We reasoned that evidence for the nature of energy at

Molecular evolution of the Chlamydiaceae. [PDF]
Phylogenetic analyses of surface antigens and other chlamydial proteins were used to reconstruct the evolution of the Chlamydiaceae. Trees for all five coding genes [the major outer-membrane protein (MOMP), GroEL chaperonin, KDO-transferase, small cysteine-rich lipoprotein and 60 kDa cysteine-rich protein] supported the current organization of the ...

The dual nature of TDC – bridging dendritic and T cells in immunity
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Bacterial N4-methylcytosine as an epigenetic mark in eukaryotic DNA
Eukaryotic DNA can be methylated as 5-methylcytosine and N6-methyladenine, but whether other forms of DNA methylation occur has been controversial. Here the authors show that a bacterial DNA methyltransferase was acquired >60 Mya in bdelloid rotifers ...

In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
