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

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 ...

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 ...

Epidemicity conditions in spatial models of infectious diseases

Andrea Rinaldo, Cristiano Trevisin

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 ...

Disentangling Multiple System Atrophy - Structural insights from alpha-synuclein fibrils and tissue pathology

Domenic Burger

Multiple System Atrophy (MSA) is an aggressive neurodegenerative disorder characterized by the formation of Glial Cytoplasmic Inclusions (GCI) containing alpha-synuclein (aSyn) fibrils in brain tissue. The fundamental causes for many neurodegenerative dise ...

Diffusion of brain metabolites highlights altered brain microstructure in type C hepatic encephalopathy: a 9.4 T preliminary study

Cristina Ramona Cudalbu Moldovan, Dunja Simicic, Katarzyna Pierzchala, Jessie Julie Mosso, Guillaume Miro André Briand

Introduction Type C hepatic encephalopathy (HE) is a decompensating event of chronic liver disease leading to severe motor and cognitive impairment. The progression of type C HE is associated with changes in brain metabolite concentrations measured by 1H m ...

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 ...

Nutritional metabolism and cerebral bioenergetics in Alzheimer's disease and related dementias

Johannes Gräff, Giulia Santoni

Disturbances in the brain's capacity to meet its energy demand increase the risk of synaptic loss, neurodegeneration, and cognitive decline. Nutritional and metabolic interventions that target metabolic pathways combined with diagnostics to identify defici ...

Effect of freezing of gait and dopaminergic medication in the biomechanics of lower limbs in the gait of patients with Parkinson's disease compared to neurologically healthy

Solaiman Shokur

Introduction: This study aims to evaluate the effects of medication, and the freezing of gait (FoG) on the kinematic and kinetic parameters of gait in people with Parkinson's disease (pwPD) compared to neurologically healthy. Methods: Twenty-two people wit ...

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 ...

Pathological Relevance of Post-Translationally Modified Alpha-Synuclein (pSer87, pSer129, nTyr39) in Idiopathic Parkinson's Disease and Multiple System Atrophy

Hilal Lashuel, Melek Firat Altay

Aggregated alpha-synuclein (alpha-synuclein) is the main component of Lewy bodies (LBs), Lewy neurites (LNs), and glial cytoplasmic inclusions (GCIs), which are pathological hallmarks of idiopathic Parkinson's disease (IPD) and multiple system atrophy (MSA ...

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 ...

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 ...

Functional connectivity underlying cognitive and psychiatric symptoms in post-COVID-19 syndrome: is anosognosia a key determinant?

Dimitri Nestor Alice Van De Ville, Alessandra Griffa

Lack of awareness of cognitive impairment (i.e. anosognosia) could be a key factor for distinguishing between neuropsychological postCOVID-19 condition phenotypes. In this context, the 2-fold aim of the present study was to (i) establish the prevalence of ...

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 ...

FTLD-TDP assemblies seed neoaggregates with subtype-specific features via a prion-like cascade

Henning Paul-Julius Stahlberg, Amanda Jennifer Lewis, Marta Di Fabrizio

Morphologically distinct TDP-43 aggregates occur in clinically different FTLD-TDP subtypes, yet the mechanism of their emergence and contribution to clinical heterogeneity are poorly understood. Several lines of evidence suggest that pathological TDP-43 fo ...
