Features:

Acer okamotoanum - Acer okamotoanum Extract

Alternative Names: Acer okamotoanum, Ulleungdo maple

Type: Botanical extract / flavonoid-rich plant product

Source: Acer okamotoanum is a maple species native to Korea, particularly Ulleung Island. Experimental studies have used leaf extracts and solvent fractions, including flavonoid-rich ethyl acetate fractions.

Active Constituents: Reported constituents include isoquercitrin, quercitrin, afzelin, and other phenolic and flavonoid compounds.

Function: Acer okamotoanum extracts exhibit antioxidant, anti-inflammatory, cytoprotective, and neuroprotective activities. Experimental studies show reductions in reactive oxygen species, lipid peroxidation, inflammatory signaling, and apoptotic damage, together with preservation of neuronal viability and cellular stress resistance.

Alzheimer's Disease: Preclinical evidence suggests potential neuroprotective and cognition-preserving effects. Acer okamotoanum extract has improved learning and memory and reduced oxidative stress in experimental models involving amyloid-β and metabolic stress. Constituents including isoquercitrin, quercitrin, and afzelin may contribute to these effects through antioxidant, anti-inflammatory, and amyloid-related mechanisms. Clinical efficacy for Alzheimer's disease has not been established.

Type:

PSEN2 - Presenilin 2

Type: Intramembrane aspartyl protease / catalytic γ-secretase complex subunit

Function: PSEN2 is a catalytic component of the γ-secretase complex, together with nicastrin, APH1, and PEN2. The complex performs intramembrane proteolysis of multiple substrates including amyloid precursor protein (APP) and Notch receptors. γ-Secretase cleavage of APP generates amyloid-β peptides including Aβ40 and Aβ42. PSEN2 also participates in endolysosomal, calcium, mitochondrial, and cellular signaling functions.

Alzheimer's Disease: ↕ Altered function. Pathogenic PSEN2 mutations cause rare autosomal-dominant familial Alzheimer's disease by altering γ-secretase processing of APP. Many disease-associated mutations increase the relative production of aggregation-prone Aβ42, producing an increased Aβ42/Aβ40 ratio. The primary Alzheimer's mechanism therefore reflects altered PSEN2/γ-secretase activity rather than a consistent increase or decrease in PSEN2 expression.
