Background: The Apolipoprotein E4 isoform (ApoE4), encoded by the APOE gene, stands out as the most influential genetic factor in late-onset Alzheimer's disease (LOAD). The ApoE4 isoform contributes to metabolic and neuropathological abnormalities during brain aging, with a strong correlation observed in APOE4-positive Alzheimer's disease cases between phosphorylated tau burden and amyloid deposition. Despite compelling evidence of APOE-mediated neuroinflammation influencing the progression of tau-mediated neurodegeneration, the molecular mechanisms underlying these phenomena remain largely unknown.

Alzheimers Dement
December 2024
Edith Cowan University, Perth, Western Australia, Australia.
Background: Accumulation of amyloid beta 42 (Aβ42) senile plaques is the most critical event leading to Alzheimer's disease (AD). Currently approved drugs for AD have not been able to effectively modify the disease. This has caused increasing research interests in health beneficial nutritious plant foods as viable alternative therapy to prevent or manage AD.

Dihydroxytrimethoxyflavone, a natural flavone found in herbal drugs, is documented to be neuroprotective in different model systems. Nevertheless, possible memory improvement effects of dihydroxytrimethoxyflavone via nuclear factor-E2-related factor 2 (Nrf2) (a crucial regulator of antioxidative system) has not been systematically evaluated.

Targeting this multifactorial disease by repurposing FDA approved drugs serves as a faster mode of treatment due to its pre-established human safety. We tested terazosin (TZ), an a-1 adrenergic receptor (AR) antagonist and phosphoglycerate kinase-1 (PGK1) activator as having potential to treat AD.

Shoolini University, Solan, Himachal Pradesh, India.
Background: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive decline, neuroinflammation, and mitochondrial dysfunction. In Alzheimer's, abnormal Mitochondrial Permeability Transition Pore (mPTP) activity may contribute to mitochondrial dysfunction and neuronal damage. Withanolide A, a naturally occurring compound derived from Withania somnifera, have shown potential neuroprotective effects in various neurological disorders.
