Following spatial A beta aggregation dynamics in evolving Alzheimer's disease pathology by imaging stable isotope labeling kinetics

Anders Meibom, Stéphane Laurent Escrig, Melissa Kathleen Passarelli

beta-Amyloid (A beta) plaque formation is the major pathological hallmark of Alzheimer's disease (AD) and constitutes a potentially critical, early inducer driving AD pathogenesis as it precedes other pathological events and cognitive symptoms by decades. ...

Identification of new Presenilin-1 phosphosites: implication for gamma-secretase activity and A beta production

Romain Hamelin, Patrick Fraering, Marc Moniatte, Mitko Dimitrov, Sébastien Mosser, Alexandre Matz, Blanka Halamoda

An important pathological hallmark of Alzheimer's disease (AD) is the deposition of amyloid-beta (A) peptides in the brain parenchyma, leading to neuronal death and impaired learning and memory. The protease -secretase is responsible for the intramembrane ...

EARLY-ONSET DYSFUNCTION OF RETROSPLENIAL CORTEX PRECEDES OVERT AMYLOID PLAQUE FORMATION IN Tg2576 MICE

Guillaume Poirier

A mouse model of amyloid pathology was used to first examine using a cross sectional design changes in retrosplenial cortex activity in transgenic mice aged 5, 11, 17, and 23 months. Attention focused on: (1) overt amyloid labeled with beta-amyloid((1-42)) ...

Dynamics of the microglial/amyloid interaction indicate a role in plaque maintenance

Tristan Bolmont

Microglial cells aggregate around amyloid plaques in Alzheimer's disease, but, despite their therapeutic potential, various aspects of their reactive kinetics and role in plaque pathogenesis remain hypothetical. Through use of in vivo imaging and quantitat ...

Electron diffraction and high resolution transmission electron microscopy in the characterization of calcium phosphate precipitation from aqueous solutions under biomineralization conditions

Philippe Buffat, Elena Suvorova Buffat

Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...

Calcium phosphate precipitation under biomineralization conditions: Effect of microgravity

Elena Suvorova Buffat

Structure and morphology of solid particles in precipitation from aqueous solutions correlate with formation (solution) conditions and thus reflect the growth mechanism. Calcium phosphate precipitation obtained from dilute aqueous solutions at room and bod ...
