This study reveals that the chick embryo has active the machinery for the production and degradation of the amyloid beta peptide characteristic of Alzheimer's disease. We cloned the principal beta-amyloid precursor protein isoforms in the chick embryo and observed that they are highly homologous to the human sequences and identical at the C-terminal(More)
Using immunostaining during early zebrafish embryogenesis, we report that the cranial and trunk neural crest expresses the paired box protein Pax7, thus revealing a novel neural crest marker in zebrafish. In the head, we show that Pax7 is broadly expressed in the cranial crest cells, which indicates that duplication of the paralogous group Pax3/7 at the(More)
Neural crest cells are considered a key vertebrate feature that is studied intensively because of their relevance to development and evolution. Here we report the expression of Pax7 in the dorsal non-neural ectoderm and in the trunk neural crest of the early chick embryo. Pax7 is expressed in the trunk neural crest migrating along the ventral and(More)
Recent advances in neuroimaging and cerebrospinal fluid (CSF) biomarker assays have provided evidence of a long preclinical stage of Alzheimer's disease (AD). This period is being increasingly targeted for secondary prevention trials of new therapies. In this context, the interest of a noninvasive, cost-effective amyloid-β (Aβ) blood-based test does not(More)
