Epidemicity conditions in spatial models of infectious diseases

We review the work that has been conducted in the past years to understand when and why significant epidemics may arise even though a disease is not bound to become endemic in the long run i.e. subthreshold outbreaks. In particular, we describe the methods ...

Structural basis of BAK sequestration by MCL-1 in apoptosis

Alexander Myasnikov, Emiko Uchikawa

Apoptosis controls cell fate, ensuring tissue homeostasis and promoting disease when dysregulated. The rate-limiting step in apoptosis is mitochondrial poration by the effector B cell lymphoma 2 (BCL-2) family proteins BAK and BAX, which are activated by i ...

The genetic background shapes the susceptibility to mitochondrial dysfunction and NASH progression

Johan Auwerx, Maroun Bou Sleiman, Jean-David Horacio Morel, Giorgia Benegiamo, Ludger Jan Elzuë Goeminne, Sandra Rodriguez Lopez, Giacomo Vincenzo Giorgio Von Alvensleben, Alexis Maximilien Bachmann

Mice from different genetic backgrounds have widely diverse responses to the same metabolic challenges. Only PWK/PhJ mice show significant mitochondrial dysfunction and progression to fibrotic NASH that resembles human NASH. The PWK/PhJ strain is a novel N ...

Single-Particle Tracking and Trajectory Analysis of Fluorescent Nanodiamonds in Cell-Free Environment and Live Cells

Mayeul Sylvain Chipaux

Diamond magnetometry can provide new insights on the production of free radicals inside live cells due to its high sensitivity and spatial resolution. However, the measurements often lack intracellular context for the recorded signal. In this paper, the po ...

Towards elucidating the structural and cellular determinants of a-synuclein seeding and toxicity

Somanath Jagannath

Although it has been nearly two and half decades since the discovery of alpha-synuclein (aSyn) as the major component of Lewy bodies (LBs), our understanding of the involvement of different aSyn species, their seeding, spreading and toxicity in Parkinson's ...

Alpha-synuclein as a Potential Biomarker for Parkinson’s Disease and Other Synucleinopathies: Gaps, Challenges, and Opportunities

Hilal Lashuel, Pedro José Santana Ribeiro Magalhães

Parkinson's disease (PD), the second most common progressive neurodegenerative disease, develops and progresses for 10-15 years before the clinical diagnostic symptoms of the disease are manifested. Furthermore, several aspects of PD pathology overlap with ...

Alpha-synuclein research: defining strategic moves in the battle against Parkinson's disease

Hilal Lashuel

With the advent of the genetic era in Parkinson's disease (PD) research in 1997, alpha-synuclein was identified as an important player in a complex neurodegenerative disease that affects >10 million people worldwide. PD has been estimated to have an econom ...

Clinical and Genetic Findings of Autosomal Recessive Bestrophinopathy (ARB)

Daniel Francis Schorderet

Mutations in BEST1 cause several phenotypes including autosomal dominant (AD) Best vitelliform macular dystrophy type 2 (BVMD), AD vitreo-retino-choroidopathy (ADVIRC), and retinitis pigmentosa-50 (RP50). A rare subtype of Bestrophinopathy exists with bial ...

Predicting the Occurrence of Variants in RAG1 and RAG2

Jacques Fellay, Flavia Aurelia Shoko Hodel, Dylan Lawless

While widespread genome sequencing ushers in a new era of preventive medicine, the tools for predictive genomics are still lacking. Time and resource limitations mean that human diseases remain uncharacterized because of an inability to predict clinically ...

Calorie restriction slows age-related microbiota changes in an Alzheimer's disease model in female mice

Julia Chiara Vincentini

Alzheimer's disease (AD) affects an estimated 5.8 million Americans, and advanced age is the greatest risk factor. AD patients have altered intestinal microbiota. Accordingly, depleting intestinal microbiota in AD animal models reduces amyloid-beta (A beta ...

Inflammatory arthritis and systemic bone loss are attenuated by gastrointestinal helminth parasites

Nicola Harris, Mario Michael Zaiss, Manuel Kulagin

Infections with different helminth species have been observed to ameliorate a variety of chronic inflammatory diseases. Herein, we show that the natural murine helminth species, Heligmosomoides polygyrus bakeri (Hp) is capable of attenuating disease severi ...

SOD1 silencing in motoneurons or glia rescues neuromuscular function in ALS mice

Patrick Aebischer, Bernard Schneider, Cylia Cloé Rochat, Christopher Towne, Elisabeth Anne Dirren, Julianne Bobela

Objective: Amyotrophic lateral sclerosis is an incurable disorder mainly characterized by motoneuron degeneration. Mutations in the superoxide dismutase 1 (SOD1) gene account for 20% of familial forms of the disease. Mutant SOD1 exerts multiple pathogenic ...

A potent and selective Sirtuin 1 inhibitor alleviates pathology in multiple animal and cell models of Huntington's disease

Protein acetylation, which is central to transcriptional control as well as other cellular processes, is disrupted in Huntington's disease (HD). Treatments that restore global acetylation levels, such as inhibiting histone deacetylases (HDACs), are effecti ...

Molecular basis of telomere syndrome caused by CTC1 mutations

Joachim Lingner, Liuh-Yow Chen, Jana Majerská

Mutations in CTC1 lead to the telomere syndromes Coats Plus and dyskeratosis congenita (DC), but the molecular mechanisms involved remain unknown. CTC1 forms with STN1 and TEN1 a trimeric complex termed CST, which binds ssDNA, promotes telomere DNA synthes ...

Gene expression profiling of R6/2 transgenic mice with different CAG repeat lengths reveals genes associated with disease onset and progression in Huntington's disease

R6/2 transgenic mice with expanded CAG repeats (> 300) have a surprisingly prolonged disease progression and longer lifespan than prototypical parent R6/2 mice (carrying 150 CAGs); however, the mechanism of this phenotype amelioration is unknown. We compar ...

Structure and function of the molecular chaperone Hsp104 from yeast

Hilal Lashuel

The molecular chaperone Hsp104 plays a central role in the clearance of aggregates after heat shock and the propagation of yeast prions. Hsp104's disaggregation activity and prion propagation have been linked to its ability to resolubilize or remodel prote ...
