Discovery and characterization of novel stable tau oligomeric complexes: Implications for the role of Tau/phospholipid interactions in regulating its functions in health and disease

Hilal Lashuel, Anne-Laure Mahul Mellier, Nadine Aït Bouziad, Gizem Zorludemir

The microtubule-associated protein Tau plays a central role in the pathogenesis of Alzheimer's disease. Although Tau interaction with membranes is thought to affect some of its physiological functions and its aggregation properties, the sequence determinan ...

Revealing Assembly of a Pore-Forming Complex Using Single-Cell Kinetic Analysis and Modeling

Françoise Gisou van der Goot Grunberg, Felix Naef, Mirko Bischofberger, Daniel Boss, Mircea Ioan Iacovache

Many biological processes depend on the sequential assembly of protein complexes. However, studying the kinetics of such processes by direct methods is often not feasible. As an important class of such protein complexes, pore-forming toxins start their jou ...

Viral RNA Degradation and Diffusion Act as a Bottleneck for the Influenza A Virus Infection Efficiency

Christian Sieben

After endocytic uptake, influenza viruses transit early endosomal compartments and eventually reach late endosomes. There, the viral glycoprotein hemagglutinin (HA) triggers fusion between endosomal and viral membrane, a critical step that leads to release ...

Semisynthetic and in Vitro Phosphorylation of Alpha-Synuclein at Y39 Promotes Functional Partly Helical Membrane-Bound States Resembling Those Induced by PD Mutations

Hilal Lashuel, Bruno Claude Daniel Fauvet, Anne-Laure Mahul Mellier, Carole Desobry, Farah El Turk, Ana Jovicic

Alpha-synuclein is a presynaptic protein of poorly understood function that is linked to both genetic and sporadic forms of Parkinson's disease. We have proposed that alpha-synuclein may function specifically at synaptic vesicles docked at the plasma membr ...

Nano Secondary Ion Mass Spectrometry Imaging of Dopamine Distribution Across Nanometer Vesicles

Anders Meibom, Anna Larsson

We report an approach to spatially resolve the content across nanometer neuroendocrine vesicles in nerve-like cells by correlating super high-resolution mass spectrometry imaging, NanoSIMS, with transmission electron microscopy (TEM). Furthermore, intracel ...

Proteolytic processing of the synaptic cell adhesion molecule neurexin-3beta and the neurobiological functions of the resulting cleavage products

Magda Maria Palczynska

Neurexins are key synaptic cell adhesion molecules involved in synapse specification and maturation. They couple synaptic activity and cell adhesion to regulate activity-dependent synapse development. Recently, neurexin processing by alpha- and gamma- secr ...

Ultrastructural analysis of adult mouse neocortex comparing aldehyde perfusion with cryo fixation

Carl Petersen, Graham Knott, Natalya Korogod

Analysis of brain ultrastructure using electron microscopy typically relies on chemical fixation. However, this is known to cause significant tissue distortion including a reduction in the extracellular space. Cryo fixation is thought to give a truer repre ...

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

Henry Markram, Ralf Schneggenburger, Olexiy Kochubey, Felix Schürmann, Yunyun Han, Daniel Keller, 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 ...
