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 ...

Computationally designed GPCR quaternary structures bias signaling pathway activation

Patrick Daniel Barth, Robert Everett Jefferson

Communication across membranes controls critical cellular processes and is achieved by receptors translating extracellular signals into selective cytoplasmic responses. While receptor tertiary structures can be readily characterized, receptor associations ...

FM19G11-Loaded Gold Nanoparticles Enhance the Proliferation and Self-Renewal of Ependymal Stem Progenitor Cells Derived from ALS Mice

Francesco Stellacci

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons. In ALS mice, neurodegeneration is associated with the proliferative restorative attempts of ependymal stem progenitor cells (epSPCs) that normally lie i ...

Computer vision profiling of neurite outgrowth dynamics reveals spatio-temporal modularity of Rho GTPase signaling

Pascal Fua, François Fleuret, Kevin Smith, Germán González Serrano

Rho guanosine triphosphatases (GTPases) control the cytoskeletal dynamics that power neurite outgrowth. This process consists of dynamic neurite initiation, elongation, retraction, and branching cycles that are likely to be regulated by specific spatiotemp ...

Intercellular ultrafast Ca2+ wave in vascular smooth muscle cells: numerical and experimental study

Jean-Jacques Meister, Niccolo Piacentini, Franck Claude Raynaud, Jairo Camilo Quijano Perez

Vascular smooth muscle cells exhibit intercellular Ca2+ waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca2+ wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave w ...

An Exclusion Zone for Ca2+ Channels around Docked Vesicles Explains Release Control by Multiple Channels at a CNS Synapse

Henry Markram, Felix Schürmann, Ralf Schneggenburger, Daniel Keller, Olexiy Kochubey, Yunyun Han, Zsolt Norbert Babai

The spatial arrangement of Ca2+ channels and vesicles remains unknown for most CNS synapses, despite of the crucial importance of this geometrical parameter for the Ca2+ control of transmitter release. At a large model synapse, the calyx of Held, transmitt ...

Cell intrinsic immunity spreads to bystander cells via the intercellular transfer of cGAMP

Andrea Ablasser

The innate immune defence of multicellular organisms against microbial pathogens requires cellular collaboration. Information exchange allowing immune cells to collaborate is generally attributed to soluble protein factors secreted by pathogen-sensing cell ...

Malaria parasites form filamentous cell-to-cell connections during reproduction in the mosquito midgut

Physical contact is important for the interaction between animal cells, but it can represent a major challenge for protists like malaria parasites. Recently, novel filamentous cell-cell contacts have been identified in different types of eukaryotic cells a ...

Membrane nanotubes drawn by optical tweezers transmit electrical signals between mammalian cells over long distances

Horst Vogel, Marinela Gjoni Boillat, Pedro Pascoal, Davor Kosanic

Biological cells continuously change shape allowing essential functions such as cell motility, vesicle-mediated release/uptake of soluble and membrane components or nanotube-mediated cell–cell communications. Here we use single cell micromanipulation to in ...
