Complex Regulation of gamma-Secretase: from Obligatory to Modulatory Subunits
Frontiers in Aging Neuroscience, 2015 gamma-Secretase is a four subunit, 19-pass transmembrane enzyme that cleaves amyloid precursor protein, catalyzing the formation of amyloid beta peptides that form amyloid plaques, which contribute to Alzheimer’s disease pathogenesis.

Controlled cortical impact traumatic brain injury in 3xTg-AD mice causes acute intra-axonal amyloid-β accumulation and independently accelerates the development of tau abnormalities [PDF]
, 2011 Alzheimer\u27s disease (AD) is a neurodegenerative disorder characterized pathologically by progressive neuronal loss, extracellular plaques containing the amyloid-β (Aβ) peptides, and neurofibrillary tangles composed of hyperphosphorylated tau proteins.

Alzheimer-mutant γ-secretase complexes stall amyloid β-peptide production
eLifeMissense mutations in the amyloid precursor protein (APP) and presenilin-1 (PSEN1) cause early-onset familial Alzheimer’s disease (FAD) and alter proteolytic production of secreted 38-to-43-residue amyloid β-peptides (Aβ) by the PSEN1-containing γ ...

A reporter for amyloid precursor protein γ-secretase activity in Drosophila [PDF]
, 2003 A key event in the pathogenesis of Alzheimer's disease (AD) is the deposition of senile plaques consisting largely of a peptide known as β-amyloid (Aβ) that is derived from the amyloid precursor protein (APP).

Advanced Healthcare Materials, EarlyView.Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs

The Uppsala APP Mutation Promotes Wild‐Type Amyloid‐β Aggregation and Deposition In Vivo
Advanced Science, EarlyView.We investigated in vivo cross‐seeding of amyloid‐β (Aβ) isoforms in transgenic mice co‐expressing wild‐typeAβ and the Uppsala‐mutant Aβ variant (AβUpp), lacking six central residues. Weleveraged MALDI‐MS imaging and hyperspectral microscopy to follow spatio‐temporalAβ deposition.

Amyloid proteotoxicity initiates an inflammatory response blocked by cannabinoids. [PDF]
, 2016 The beta amyloid (Aβ) and other aggregating proteins in the brain increase with age and are frequently found within neurons. The mechanistic relationship between intracellular amyloid, aging and neurodegeneration is not, however, well understood.
