Amyloid β-protein (Aβ) assembly is hypothesized to be a seminal neuropathologic event in Alzheimer's disease (AD). We used an unbiased D-amino acid substitution strategy to determine structure-assembly relationships of 76 different Aβ40 and Aβ42 peptides. We determined the effects of the substitutions on peptide oligomerization, secondary structure(More)
Unlike mammals, zebrafish can regenerate their injured spinal cord and regain control of caudal tissues. It was recently shown that Wnt/β-catenin signaling is necessary for spinal cord regeneration in the larval zebrafish. However, the molecular mechanisms of regeneration may or may not be conserved between larval and adult zebrafish. To test this, we(More)
