Neural anticipation of virtual infection triggers an immune response

Once contact with a pathogen has occurred, it might be too late for the immune system to react. Here, we asked whether anticipatory neural responses might sense potential infections and signal to the immune system, priming it for a response. We show that p ...

Self-driving microscopy detects the onset of protein aggregation and enables intelligent Brillouin imaging

Camille Valentine Cathala, Hilal Lashuel, Aleksandra Radenovic, Lely Feletti, Khalid Ashraf Mohie Ibrahim

The process of protein aggregation, central to neurodegenerative diseases like Huntington’s, is challenging to study due to its unpredictable nature and relatively rapid kinetics. Understanding its biomechanics is crucial for unraveling its role in disease ...

Antagonism as a Foraging Strategy in Microbial Communities

Martin Ackermann, Lucas Pierre Antoine Paoli

In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependent antagonism. Using single-cell live imaging and isotopi ...

Clinical Significance of the 5T;12TG Genotype in Pediatric CFSPID: A Retrospective Study

Simon Christian J Boutry

Background: One of the most common genetic variants among individuals with cystic fibrosis screen-positive inconclusive diagnosis (CFSPID) is 5T;12TG. Classified as having “varying clinical consequences” (VVCC), it may produce a wide spectrum of CF phenoty ...

HPV16-Expressing Tumors Release Multiple IL-1 Ligands to Orchestrate Systemic Immunosuppression Whose Disruption Enables Efficacy of a Therapeutic Vaccine

Marjorie Gabrielle Marie Cayatte, Dilara Selin Ozdoganlar, Douglas Hanahan, Krisztian Homicsko, Morgane Marie Lecointre, Jeremy Gilles Louis Guillot

It is well-established that symptomatic cancers evade immune destruction by coalescing tumor microenvironments to suppress adaptive immunity. Additionally, mouse models of cervical and other cancers have revealed a capability of tumors to systemically indu ...

Lactoferrin-osteopontin complexes: insights into intestinal organoid bioavailability and gut microbiota modulation

Loïc Dayon

Lactoferrin (LF) and osteopontin (OPN) are key bioactive milk proteins with significant immunemodulatory, gut, and systemic health benefits. We investigated the bioavailability and intestinal uptake dynamics of bovine LF-OPN soluble complexes (SC) and comp ...

A novel allosteric GCase modulator prevents Tau accumulation in GBA1WT and GBA1L444P/L444P cellular models

Maurizio Molinari

A slow decline in the autophagy-lysosomal pathway is a hallmark of the normal aging brain. Yet, an acceleration of this cellular function may propel neurodegenerative events. In fact, mutations in genes associated with the autophagy-lysosomal pathway can l ...

Convalescent human plasma candidate reference materials protect against Crimean-Congo haemorrhagic fever virus (CCHFV) challenge in an A129 mouse model

Frank William Charlton

Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is spread by infected ticks or direct contact with blood, tissues and fluids from infected patients or livestock. Infection with CCHFV causes severe haemorrhagic fever in humans which is fatal in up to 83 % of ...

Brain mitochondrial diversity and network organization predict anxiety-like behavior in male mice

Maria del Carmen Sandi Perez

The brain and behavior are under energetic constraints, limited by mitochondrial energy transformation capacity. However, the mitochondria-behavior relationship has not been systematically studied at a brain-wide scale. Here we examined the association bet ...

Parental status and markers of brain and cellular age: A 3D convolutional network and classification study

Donal Patrick Hill

Recent research shows prominent effects of pregnancy and the parenthood transition on structural brain characteristics in humans. Here, we present a comprehensive study of how parental status and number of children born/fathered links to markers of brain a ...

Overexpression of human alpha-Synuclein leads to dysregulated microbiome/metabolites with ageing in a rat model of Parkinson disease

Joan Romani Aumedes, Hilal Lashuel, Yogesh Singh Chauhan, Florian Lang

Background Braak's hypothesis states that sporadic Parkinson's disease (PD) follows a specific progression of pathology from the peripheral to the central nervous system, and this progression can be monitored by detecting the accumulation of alpha-Synuclei ...
