Unraveling mitochondrial dynamics: exploring asymmetries and function through advanced microscopy

Still displaying characteristics of their bacterial origin, such as autonomous division, motility, and their own genome, mitochondria remain an elusive component of modern eukaryotes. They produce most of the cell's energy in the form of adenosine triphosp ...

Biotechnological Frontiers of DNA Nanomaterials Continue to Expand: Bacterial Infection using Virus-Inspired Capsids

Maartje Martina Cornelia Bastings

The elegant geometry of viruses has inspired bio-engineers to synthetically explore the self-assembly of polyhedral capsids employed to protect new cargo or change an enzymatic microenvironment. Recently, Yang and co-workers used DNA nanotechnology to revi ...

Phylogenetic estimation of the viral fitness landscape of HIV-1 set-point viral load

Jacques Fellay, Luca Ferretti

Set-point viral load (SPVL), a common measure of human immunodeficiency virus (HIV)-1 virulence, is partially determined by viral genotype. Epidemiological evidence suggests that this viral property has been under stabilising selection, with a typical opti ...

Human T-Cell Lymphotropic Virus Type 1 Transactivator Tax Exploits the XPB Subunit of TFIIH during Viral Transcription

Human T-cell lymphotropic virus type 1 (HTLV-1) Tax oncoprotein is required for viral gene expression. Tax transactivates the viral promoter by recruiting specific transcription factors but also by interfering with general transcription factors involved in ...

Infrared nanospectroscopic mapping of a single metaphase chromosome

Giovanni Dietler, Andrzej Kulik, Francesco Simone Ruggeri, Ewelina Wioletta Lipiec

The integrity of the chromatin structure is essential to every process occurring within eukaryotic nuclei. However, there are no reliable tools to decipher the molecular composition of metaphase chromosomes. Here, we have applied infrared nanospectroscopy ...

E-coli-MS2 bacteriophage interactions during solar disinfection of wastewater and the subsequent post-irradiation period

César Pulgarin, Anna Carratala Ripolles, Stefanos Giannakis, Margaux Océane Voumard

In this study, the effect of MS2 bacteriophage on the inactivation of its Escherichia coli host was evaluated in an effort to recreate some the main factors governing solar disinfection of wastewater (namely microbial growth, infection, photonic flux). As ...

An Atomistic Look into Bio-inspired Nanoparticles and their Molecular Interactions with Cells

Francesco Stellacci, Alke Fink, Pablo Campomanes Ramos, Stefano Vanni

Nanoparticles (NPs) have sizes that approach those of pathogens and they can interact with the membranes of eukaryotic cells in an analogous fashion. Typically, NPs are taken up by the cell via the plasma membrane by receptor-mediated processes and subsequ ...

Viral genetic variation accounts for a third of variability in HIV-1 set-point viral load in Europe

Jacques Fellay

HIV-1 set-point viral load-the approximately stable value of viraemia in the first years of chronic infection-is a strong predictor of clinical outcome and is highly variable across infected individuals. To better understand HIV-1 pathogenesis and the evol ...

Positive Selection Drives Preferred Segment Combinations during Influenza Virus Reassortment

Jeffrey David Jensen, Matthieu Foll

Influenza A virus (IAV) has a segmented genome that allows for the exchange of genome segments between different strains. This reassortment accelerates evolution by breaking linkage, helping IAV cross species barriers to potentially create highly virulent ...
