In vivo X-ray microtomography locally affects stem radial growth with no immediate physiological impact

Pascal Turberg, Charlotte Grossiord, Laura Mekarni, Hervé Cochard

Microcomputed tomography (mu CT) is a nondestructive X-ray imaging method used in plant physiology to visualize in situ plant tissues that enables assessments of embolized xylem vessels. Whereas evidence for X-ray-induced cellular damage has been reported, ...

An autologous antigen-agnostic dendritic cell therapy that forgoes antigen loading

Michele De Palma

We developed a method for generating dendritic cell progenitors (DCPs) from hematopoietic stem and progenitor cells isolated from bone marrow or blood. When engineered to express IL-12 and FLT3L, these DCPs reprogram the tumor microenvironment and elicit a ...

Heterogeneity and developmental dynamics of mammalian neocortical progenitors

Gioele La Manno, Antonio Herrera Camacho, Leila Haj Abdullah Alieh

The central nervous system develops from a pool of neural progenitors which, depending on their location and time of division, generate cells committed to differentiate into specific kinds of neurons or glia. In the last decades, the developmental neurobio ...

Online interoperable resources for building hippocampal neuron models via the Hippocampus Hub

Armando Romani, Felix Schürmann, Michele Migliore, Luca Leonardo Bologna

To build biophysically detailed models of brain cells, circuits, and regions, a data-driven approach is increasingly being adopted. This helps to obtain a simulated activity that reproduces the experimentally recorded neural dynamics as faithfully as possi ...

Neurogenesis redirects β-catenin from adherens junctions to the nucleus to promote axonal growth

Antonio Herrera Camacho

Here, we show that, in the developing spinal cord, after the early Wnt-mediated Tcf transcription activation that confers dorsal identity to neural stem cells, neurogenesis redirects beta-catenin from the adherens junctions to the nucleus to stimulate Tcfo ...

Comprehensive proteomic analysis of JC polyomavirus-infected human astrocytes and their extracellular vesicles

Alexey Sapozhnik, Samuel Jones

JC polyomavirus (JCPyV) is an opportunistic virus that remains in a latent state in the kidneys and lymphoid organs of more than half of the human adult population. In rare cases of severe immune suppression, the virus is able to establish a lytic infectio ...

Playing Brains: The Ethical Challenges Posed by Silicon Sentience and Hybrid Intelligence in DishBrain

The convergence of human and artificial intelligence is currently receiving considerable scholarly attention. Much debate about the resulting Hybrid Minds focuses on the integration of artificial intelligence into the human brain through intelligent brain- ...

Species-specific regulation of XIST by the JPX/FTX orthologs

Olga Marie Louise Rosspopoff

X chromosome inactivation (XCI) is an essential process, yet it initiates with remarkable diversity in various mammalian species. XIST, the main trigger of XCI, is controlled in the mouse by an interplay of lncRNA genes (LRGs), some of which evolved concom ...

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 ...

Disruption of stem cell niche-confined R-spondin 3 expression leads to impaired hematopoiesis

Freddy Radtke, Ute Koch, Jialin Zhang, Soufiane Boumahdi

Self-renewal and differentiation of stem and progenitor cells are tightly regulated to ensure tissue homeostasis. This regulation is enabled both remotely by systemic circulating cues, such as cytokines and hormones, and locally by various niche-confined f ...

Astrocyte-targeting RNA interference against mutated superoxide dismutase 1 induces motoneuron plasticity and protects fast-fatigable motor units in a mouse model of amyotrophic lateral sclerosis

Patrick Aebischer, Bernard Schneider, Nathalie Marie Géraldine Bernard, Cylia Cloé Rochat

In amyotrophic lateral sclerosis (ALS) caused by SOD1 gene mutations, both cell-autonomous and noncell-autonomous mechanisms lead to the selective degeneration of motoneurons (MN). Here, we evaluate the therapeutic potential of gene therapy targeting mutat ...

Apelin-driven endothelial cell migration sustains intestinal progenitor cells and tumor growth

Michele De Palma, Nadine Fournier, Sina Nassiri, Stefanie Siegert, Mauro Delorenzi, Mario Leonardo Squadrito, Pascale Anderle Pedone, Simone Ragusa, François Renevey

Stem and progenitor cells residing in the intestinal crypts drive the majority of colorectal cancers (CRCs), yet vascular contribution to this niche remains largely unexplored. Vascular endothelial growth factor A (VEGFA) is a key driver of physiological a ...

Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part II: Effects of Facade and Daylight Pattern Geometry

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...
