Induction of type I IFNs by intracellular DNA-sensing pathways

A successful antimicrobial immune response involves the coordinate action of cells and soluble factors, with the cytokine family of type I interferons (IFNs) having a central role. Type I IFNs are not only crucial in conferring immediate antimicrobial, mos ...

Kinetic modeling of the yeast sphingolipid metabolism identifies prevalent mutant strains through integration of lipidomic data profiles

Vassily Hatzimanikatis, Paolo Angelino, Howard Riezman, Georgios Savoglidis

Sphingolipids are abundant components of eukaryotic cells. Their localization in the plasma membrane allows for the cell to carry out multiple important functions for its viability. One of the most important roles of the sphingolipids is their ability to f ...

Contractile Tail Machines of Bacteriophages

Petr Leiman

Bacteriophages with contractile tails epitomize the concepts of "virus" and "phage" for many because the tails of these phages undergo a large conformational change - resembling the action of a syringe - upon the attachment to the host cell. The contractil ...

Sirtuins as regulators of metabolism and healthspan

Johan Auwerx, Richardus Houtkooper, Eija Riitta Pirinen

Since the beginning of the century, the mammalian sirtuin protein family (comprising SIRT1-SIRT7) has received much attention for its regulatory role, mainly in metabolism and ageing. Sirtuins act in different cellular compartments: they deacetylate histon ...

On the Equivalence of Schemes for Simulating Bilayers at Constant Surface Tension

Berend Smit

Lipid bilayers are simulated using flexible simulation cells in order to allow for relaxations in area per lipid as bilayer content and temperature are varied. We develop a suite of Monte Carlo (MC) moves designed to generate constant surface tension γ and ...

Unconventional Use of LC3 by Coronaviruses through the Alleged Subversion of the ERAD Tuning Pathway

Maurizio Molinari

Pathogens of bacterial and viral origin hijack pathways operating in eukaryotic cells in many ways in order to gain access into the host, to establish themselves and to eventually produce their progeny. The detailed molecular characterization of the subver ...

ERAD and ERAD tuning: disposal of cargo and of ERAD regulators from the mammalian ER

Maurizio Molinari, Riccardo Bernasconi

The endoplasmic reticulum (ER) is the site of maturation for secretory and membrane proteins in eukaryotic cells. Unsuccessful folding attempts are eventually interrupted and most folding-defective polypeptides are dislocated across the ER membrane and deg ...

The dynamic architecture of Hox gene clusters

Denis Duboule, Jacques Rougemont, Marion Leleu, Daniël Noordermeer

The spatial and temporal control of Hox gene transcription is essential for patterning the vertebrate body axis. Although this process involves changes in histone posttranslational modifications, the existence of particular three-dimensional (3D) architect ...

Novel nanofiber-based triple-layer proton exchange membranes for fuel cell applications

Mohammad Mahdi Hasani-Sadrabadi

New types of triple-layer membranes were fabricated using multi-step impregnation of Nation in electrospun webs based on bead-free nanofibers of sulfonated poly(ether sulfone) (SPES). The results showed that the fabricated nanofiber-filled membrane owing t ...

N-glycan structures: recognition and processing in the ER

Maurizio Molinari, Riccardo Bernasconi

The processing of Winked glycans determines secretory protein homeostasis in the eukaryotic cell. Folding and degradation of glycoproteins in the endoplasmic reticulum (ER) are regulated by molecular chaperones and enzymes recruited by specific oligosaccha ...
