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...

Everything you always wanted to know about sleep, but you were afraid to ask: expert concise guide and recommendations on assessing sleep-wake disturbances within a psychiatric context in contemporary times

OBJECTIVE: While disrupted sleep has long been linked to mental disorders there has been a notable decrease in interest and sleep-wake disorders have received low priority in psychiatric care. The aim of the paper was to present a concise guide for evaluating common sleep-wake di...

Antibody-mediated immune surveillance as an organizing axis of gut microbiota structure

Abstract Background The symbiotic interplay between the immune system and the endogenous microbiome is essential for maintaining homeostasis. However, most microbiome research focuses primarily on associations between disease and microbial composition, often overlooking host–micr...

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...

Decline of chaperone-mediated autophagy in aging impairs macrophage clearance of senescent cells

Autophagy dysfunction and senescence are established drivers of aging, but their potential interaction remains poorly understood. Here we show that age-related decline of chaperone-mediated autophagy (CMA), a pathway for selective lysosomal protein degradation, changes senescent...

Targeting the Complement C1 Proteases Using Camelid-Derived Single Domain Antibodies: Production, Characterization and Possible Application for Tissue/Fluid Analysis

Background. The complement C1r and C1s proteases initiate the classical complement pathway within the C1 complex, but emerging evidence points to additional roles in tissues, including cell-intrinsic functions linked to cancer and connective tissue disorders. Few tools are availa...

Temporal trends and seasonal patterns of violent crime in France

Violent behavior is a major public health concern, yet whether different forms of violent crime follow similar or distinct seasonal patterns remains unclear. We analyzed monthly national counts of police-recorded violent offenses in France from January 2016 to December 2024 using...

Autoantibodies neutralizing type I IFNs underlie ~5% of herpes simplex encephalitis in adults.

Inborn errors of type I interferon (IFN-I) immunity account for ∼7-8% of herpes simplex encephalitis (HSE) cases in young children, but the pathogenesis of HSE in adults is largely unknown. We report that IFN-I autoantibodies (auto-Abs) in serum/plasma samples drawn before, durin...

NKCC1 coordinates SPAK-PP1 signalling to regulate KCC2 membrane stability and seizure susceptibility.

Chloride homeostasis, and thereby the efficacy of chloride-permeable GABAA receptor signaling, depends on the dynamic balance between NKCC1 (Na+-K+-2Cl- cotransporter 1) and KCC2 (K+-Cl- cotransporter 2), which respectively mediate chloride influx and extrusion to tightly control...

A family of small proteins links c-di-GMP riboswitch signaling with sporulation in Clostridioides difficile

Abstract Cyclic diguanosine monophosphate (c-di-GMP) is a second messenger that coordinates lifestyle transitions, virulence, and developmental processes in bacteria. In Clostridioides difficile , elevated c-di-GMP levels inhibit sporulation, but the underlying mechanism remained...

Estrogen Receptor Beta Isoforms Interplay Integrates Nuclear and Extra‐Nuclear Signaling to Modulate Human Granulosa Cell Growth

Estradiol (E2) regulates ovarian follicular development and granulosa cell (GC) function primarily through estrogen receptor β (ERβ). Human GCs express several ERβ isoforms, including ERβ1, ERβ2, ERβ4, and ERβ5, but how their relative abundance modulates estrogen signaling remain...

A DNA methylation–based risk score improves prognostic stratification in myelodysplastic neoplasms

Myelodysplastic neoplasms (MDS) are clonal hematopoietic disorders characterized by ineffective hematopoiesis, cytopenias, and variable risk of progression to acute myeloid leukemia (AML). Although mutational data are already implemented into the most recent MDS risk models, (i.e...

Universal random matrix behavior of a Fermionic quantum gas

Since its initial use by Wigner in describing heavy atom spectra, random matrix theory (RMT) has found applications and revealed universal laws in diverse physical contexts, from quantum field theory to disordered systems and wireless communications. A particularly compelling app...

Platelet GPVI drives fibrotic lung remodeling

Platelets are a major reservoir of bioactive mediators, including growth factors such as transforming growth factor β1 (TGF-β1), that regulate vascular repair and tissue remodeling. Beyond these classical functions, platelets also participate in inflammatory hemostasis through ac...

International Modified Delphi Consensus on Assessment and Management of Covert Brain Infarction

BackgroundCovert brain infarction (CBI) is a frequent incidental neuroradiological finding increasingly recognized as clinically relevant due to its association with stroke, cognitive decline, and other adverse outcomes. However, substantial uncertainty remains regarding its opti...

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...

Sensitivity of neutrino oscillations to the Earth’s interior properties

Understanding the Earth’s deep interior remains challenging, as traditional geophysical methods face ambiguities in linking seismic observations to temperature, composition, or mass density variations. Atmospheric neutrinos, produced by the constant flux of cosmic rays colliding...

Medication use during pregnancy in Europe and North America: a systematic review

To describe the mean number of medications used as well as the prevalence of medication use throughout pregnancy in Europe and North America, with a focus on use by trimester, type of medication, and use of harmful medications. A systematic review was performed searching MEDLINE,...

Comprehensive profiling of brain dynamics during anesthesia across phylogeny

Abstract The behavioral effects of anesthetics are highly conserved across species, hinting at shared and fundamental underlying mechanisms. Here we compile a dataset of multiscale neural activity during wakefulness and anesthesia, encompassing human, macaque, marmoset, mouse, ze...

Mole or Early Melanoma? Rethinking Early Detection, Overdiagnosis, and the Benign–Malignant Paradigm

Melanoma early detection has been widely promoted on the assumption that diagnosing early tumors improves outcomes, but epidemiologic data increasingly challenge this assumption. In fair-skinned populations subjected to intensified surveillance, diagnoses of thin invasive and in...
