Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity

Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...

Brain matters: unveiling the distinct contributions of region, age, and sex to glia diversity and CNS function

Gioele La Manno, Zahra Moslehi, Nina-Lydia Kazakou

The myelinated white matter tracts of the central nervous system (CNS) are essential for fast transmission of electrical impulses and are often differentially affected in human neurodegenerative diseases across CNS region, age and sex. We hypothesize that ...

The role of the NF-kappaB pathway in Amyotrophic lateral sclerosis pathogenesis

Emma Charlotta Källstig

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor disorder, which results in death within a few years of diagnosis. While the cause of most cases of ALS is unknown, 10% of cases are familial (fALS), and associated with mutations in one of ov ...

A tool for mapping microglial morphology, morphOMICs, reveals brain-region and sex-dependent phenotypes

Kathryn Hess Bellwald, Lida Kanari, Martina Scolamiero

Environmental cues influence the highly dynamic morphology of microglia. Strategies to characterize these changes usually involve user-selected morphometric features, which preclude the identification of a spectrum of context-dependent morphological phenot ...

Fractal analysis in the quantification of medical imaging associated with multiple sclerosis pathology

Maria-Alexandra Paun

Backgrounds: Multiple sclerosis (MS) is an inveterate phlogistic situation characterized by focal and vaguely diffusive de-myelination and neurodegeneration, in the sphere of central nervous system (CNS). The brain's chronic inflammatory reaction includes ...

Diversity of Reactive Astrogliosis in CNS Pathology: Heterogeneity or Plasticity?

Jordan Squair

Astrocytes are essential for the development and homeostatic maintenance of the central nervous system (CNS). They are also critical players in the CNS injury response during which they undergo a process referred to as "reactive astrogliosis." Diversity in ...

Structural control energy of resting-state functional brain states reveals less cost-effective brain dynamics in psychosis vulnerability

Dimitri Nestor Alice Van De Ville, Marie Schaer

How the brain's white-matter anatomy constrains brain activity is an open question that might give insights into the mechanisms that underlie mental disorders such as schizophrenia. Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurodevelopmental dis ...

Anti-Aβ antibodies bound to neuritic plaques enhance microglia activity and mitigate tau pathology

Bernard Schneider, Philippe Colin, Vanessa Laversenne

The brain pathology of Alzheimer’s disease (AD) is characterized by the misfolding and aggregation of both the amyloid beta (Aβ) peptide and hyperphosphorylated forms of the tau protein. Initial Aβ deposition is considered to trigger a sequence of deleteri ...

Dysfunction of homeostatic control of dopamine by astrocytes in the developing prefrontal cortex leads to cognitive impairments

Graham Knott, Corrado Cali, Nicole Déglon, Tamara Zehnder, Luca Pucci, Andrea Chicca

Astrocytes orchestrate neural development by powerfully coordinating synapse formation and function and, as such, may be critically involved in the pathogenesis of neurodevelopmental abnormalities and cognitive deficits commonly observed in psychiatric dis ...

Extra-axonal restricted diffusion as an in-vivo marker of reactive microglia

Gaëtan Olivier D Rensonnet, Anne des Rieux, Benoît Macq

Reactive microgliosis is an important pathological component of neuroinflammation and has been implicated in a wide range of brain diseases including brain tumors, multiple sclerosis, Parkinson's disease, Alzheimer's disease, and schizophrenia. Mapping rea ...

Application of anti-amyloid beta immunization using encapsulated cell technology in mouse models of Alzheimer's disease

Vanessa Laversenne

Alzheimer's disease (AD) is the most common form of dementia in the elderly. AD is characterized by the deposition of two aggregated proteins: Amyloid beta (Aß) and hyperphosphorylated tau. Accumulations of these proteins are thought to be the signature ...

Fractal Analysis Of Brain Glial Cells. Fractal Dimension And Lacunarity

Maria-Alexandra Paun

Both calculated quantities in the paper, fractal dimension and lacunarity respectively, prove high precision as foreteller to classify the glial cells tissue in various brain morphologies. The importance of microglia in neurodegenerative diseases and the i ...

A viral vector based in vivo model of tauopathy to explore therapeutic strategies against tau pathology

Sameer Mohammad Khaleel Nazeeruddin

Tauopathies are neurodegenerative diseases whose common pathological feature is the intraneuronal accumulation of tau aggregates. Tau protein has various roles in the neuron, among which stabilization of microtubules (MT), regulation of synaptic activity o ...

Required growth facilitators propel axon regeneration across complete spinal cord injury

Grégoire Courtine, Mark Andrew Anderson, Nicholas David James, Cheng Wang, Sabry Leonardo Barlatey, Michael V. Sofroniew, Zhigang He

Transected axons fail to regrow across anatomically complete spinal cord injuries (SCI) in adults. Diverse molecules can partially facilitate or attenuate axon growth during development or after injury1,2,3, but efficient reversal of this regrowth failure ...

Perivascular macrophages in health and disease

Michele De Palma

Macrophages are a heterogeneous group of cells that are capable of carrying out distinct functions in different tissues, as well as in different locations within a given tissue. Some of these tissue macrophages lie on, or close to, the outer (abluminal) su ...

A Cell Atlas for the Mouse Brain

Henry Markram, Daniel Keller, Marc-Oliver Gewaltig

Despite vast numbers of studies of stained cells in the mouse brain, no current brain atlas provides region-by-region neuron counts. In fact, neuron numbers are only available for about 4% of brain of regions and estimates often vary by as much as 3-fold. ...

Activation of the STING-dependent type I interferon response reduces microglial reactivity and neuroinflammation

Hilal Lashuel, Ritwik Burai

Brain aging and neurodegeneration are associated with prominent microglial reactivity and activation of innate immune response pathways, commonly referred to as neuroinflammation. One such pathway, the type I interferon response, recognizes viral or mitoch ...

Zika virus causes supernumerary foci with centriolar proteins and impaired spindle positioning

Pierre Gönczy, Coralie Busso, Benita Wolf

Zika virus (ZIKV) causes congenital microcephaly. Although ZIKV can impair cell cycle progression and provoke apoptosis, which probably contributes to disease aetiology through depletion of neural progenitor cells, additional cellular mechanisms may be imp ...

Reducing circuit design complexity for neuromorphic machine learning systems based on Non-Volatile Memory arrays

Yusuf Leblebici, Alessandro Fumarola

Machine Learning (ML) is an attractive application of Non-Volatile Memory (NVM) arrays [1,2]. However, achieving speedup over GPUs will require minimal neuron circuit sharing and thus highly area-efficient peripheral circuitry, so that ML reads and writes ...
