Amyloid beta

APP, Abeta
This gene encodes a cell surface receptor and transmembrane precursor protein that is cleaved by secretases to form a number of peptides. Some of these peptides are secreted and can bind to the acetyltransferase complex APBB1/TIP60 to promote transcriptional activation, while others form the protein basis of the amyloid plaques found in the brains of patients with Alzheimer disease. Mutations in this gene have been implicated in autosomal dominant Alzheimer disease and cerebroarterial amyloidosis (cerebral amyloid angiopathy). Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008] (from NCBI)

Singh et al., Patiāla, India. In Pharmacol Biochem Behav, May 2014
Ligand activation of RAR and RXR in APP/PS1 transgenic mice ameliorated the symptoms of AD and reduced amyloid accumulation and tau hyperphosphorylation. Retinoids also reduce the production of pro-inflammatory cytokines and chemokines by astrocytes and the microglia.

Overexpression of PLD3 leads to a significant decrease in intracellular amyloid-β precursor protein (APP) and extracellular Aβ42 and Aβ40 (the 42- and 40-residue isoforms of the amyloid-β peptide), and knockdown of PLD3 leads to a significant increase in extracellular Aβ42 and Aβ40.
