Primer: Functions and evolution of viral proteins

ABSTRACT Viruses encode an enormous variety of proteins that jointly comprise the largest pool of protein diversity on Earth. At coarse grain, the viral pan-proteome can be partitioned into four classes of proteins that differ in their evolutionary conservation, spread across the...

MAC-explorer: bridging genome-based taxonomy and an identification tool for the Mycobacterium avium complex

The Mycobacterium avium complex (MAC) comprises genetically close nontuberculous mycobacteria responsible for human and animal infections worldwide. Increasing availability of whole-genome sequencing (WGS) data offers new opportunities for genomic surveillance and lineage trackin...

A phosphoinositide and RAB switch controls early macropinocytosis

Macropinocytosis is a non-selective endocytic process by which cells take up large amounts of extracellular fluid into giant vesicles known as macropinosomes. This mechanism is used by immune cells to sample the surroundings for antigens and can be exploited by cancer cells for n...

The human gut microbiome primes fever after vaccination

Fever is a common adverse reaction to vaccination, contributing to vaccine hesitancy and reduced uptake. To understand variation in fever risk, we longitudinally profiled fecal microbiota, oral temperature, and serological markers in 171 healthy adults receiving Severe acute resp...

Super Bloom: Fast and Precise Filter for Streaming k -Mer Queries

Approximate membership query structures are used throughout sequence bioinformatics, from read screening and metagenomic classification to assembly, indexing, and error correction. Among them, Bloom filters remain the default choice. They are not the most efficient structures in...

Provenance and competence for CHIKV and DENV of Aedes albopictus populations

Aedes albopictus is one of the world’s most hazardous invasive species, increasingly implicated in the autochthonous transmission of Chikungunya (CHIKV) and Dengue (DENV) viruses in newly colonized areas. Since invading the Mediterranean Basin several in the early 1980s, recurren...

Mastodon: the command center for large-scale lineage-tracing microscopy datasets

Understanding development in living organisms requires following the divisions, movements, and fates of cells. While advances in microscopy have enabled whole-embryo imaging at the cellular level, extracting and analyzing cell lineages from these massive datasets remains a signif...

Alpha-galactosylceramide as mRNA vaccine adjuvant modulates cellular immunity against tuberculosis and contributes to antigen-specific lung-associated T cells with a TRM-associated phenotype following prime-pull strategy

Tuberculosis (TB) remains the leading cause of death from a single infectious agent worldwide, highlighting the need for improved vaccines beyond the limited protection currently provided by the Bacillus Calmette-Guérin (BCG) vaccine. Here we investigated the immunological impact...

Emotional Responses (Intensity/Valence) Fulfill RDoC Criteria but Remain Excluded From Diagnostic Classifications of Mood Disorders

OBJECTIVES: Categorical classifications of depression, such as DSM-5 and ICD, are limited by high clinical heterogeneity, arbitrary diagnostic thresholds, and weak links to underlying pathophysiology. In line with the Research Domain Criteria (RDoC) framework, this article propos...

Impact of a Specialized Care Pathway for ICU Patients With Disorders of Consciousness: Observational Insights From an Expert Center

ABSTRACT Background Management of lasting disorders of consciousness (DoC) is complex and sometimes requires referral of patients to an expert team. We aimed to evaluate the impact of such specialized expert assessment through the description of a single‐center experience. Method...

Genome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach

Abstract Social behaviour is a heritable trait linked to well-being and mental health, yet it varies across social context, including social domains, informants and development, which may shape its underlying genomic architecture. Here, we conducted a genome-wide meta-regression...

Distinct migratory dendritic cell subsets cooperate to prime tissue-resident memory-like CD8⁺ T cells in mouse tumors

Tumor-infiltrating tissue-resident memory (TRM)-like CD8+ T cells correlate with positive prognosis and better responses to cancer immunotherapy, yet the mechanisms underlying their specification remain ill-understood. Here, we use the KP (KrasG12D, p53-/-) mouse model of lung ad...

Ebola business narrative and the cycle of distrust

Credibility and trust are key to transforming the response

HIPK2 loss promotes TDP-43 cytoplasmic mis-localization through MAPK-pathway and is associated with TDP-43 proteinopathy in vivo

Abstract Homeodomain Interacting Protein Kinase 2 (HIPK2) is a stress sensor kinase that has emerged as a key regulator of neuronal homeostasis and survival. In this study, we investigated the role of HIPK2 in neurodegeneration using both in vivo and in vitro models. We show that...

Advanced molecular poliovirus diagnostics across multiple real-time PCR platforms with locked nucleic acids and primer overhangs

This study details the development and validation of five real-time RT-PCR assays for the intratypic differentiation (ITD) of polioviruses and the discrimination of vaccine-derived polioviruses (VDPVs) utilizing locked nucleic acid (LNA) technology and primer overhangs. Updated a...

A novel 5-FU derivative chemotherapy: a promising pan-cancer treatment to improve antitumor efficacy and overcome therapy resistance

Abstract Management of advanced solid cancers remains challenging, particularly after the development of therapeutic resistance. Here, we synthesized a library of phosphonium-substituted 5-fluorouracil (5-FU) derivatives and evaluated their anticancer activity across multiple tum...

SPEF1 mediates assembly of central pair microtubule complexes in cilia of Tetrahymena

SPEF1 is a conserved calponin-homology domain protein that decorates the seam of central pair microtubules in the distal segment of motile cilia. Here, we show that in the ciliate Tetrahymena, loss of SPEF1 disrupts the central pair throughout the middle segment, which comprises...

A Remarkably Similar Oxygen Electronic Structure in CO-Treated CeO2 and Gd-Doped CeO2 Is Revealed by X-ray Raman Spectroscopy

Abstract CeO2 is a key material for catalytic and electrochemical applications due to its ability to store and release oxygen, linked to the formation of oxygen vacancies and the reversible reduction of Ce4+ cations to Ce3+. In this study, the oxygen K-edge was investigated in bu...

Deep learning recognises antibiotic modes of action from brightfield images

Abstract Antimicrobial resistance is a growing public health threat predicted to cause up to 10 million deaths a year by 2050. To circumvent existing bacterial resistance mechanisms, discovering antibiotics with novel modes of action (MoAs) is crucial. While growth inhibition ass...

Actin and myosin dynamics during epithelial remodeling in avian gastrulation

Epithelial remodeling is powered by contractile forces exerted by the actomyosin cytoskeleton. In invertebrates, pulsatile contractile flows of the medio-apical actomyosin cortex have been shown to be critical in promoting junction contraction, ultimately driving cell rearrangeme...
