Hydrogen sulfide inhibits A2A adenosine receptor agonist induced β-amyloid production in SH-SY5Y neuroblastoma cells via a cAMP dependent pathway. [PDF]
Alzheimer's disease (AD) is the leading cause of senile dementia in today's society. Its debilitating symptoms are manifested by disturbances in many important brain functions, which are influenced by adenosine.

Abstract Alzheimer's disease (AD) is a progressive, age‐related, neurodegenerative disorder marked by cognitive decline, memory loss, and accumulation of amyloid beta (Aβ) plaques and tau tangles. A key feature of AD is impaired protein homeostasis, often driven by autophagy dysfunction.

Aβ peptides, the major components of Alzheimer’s disease (AD) amyloid deposits, are released following sequential cleavages by secretases of its precursor named the amyloid precursor protein (APP).

Mutations Alter Conformations and Dynamics of APP‐TMDs: An RDC Analysis
How γ‐secretase selects its substrates has been an enigma because of the lack of a consensus sequence. Using residual dipolar couplings, we analyzed the conformations of one substrate and two mutants. Using snapshots of a molecular dynamics trajectory, we analyzed how well structures matched the measured RDC values.

Endosomal Sorting of Amyloid Precursor Protein‐P‐Selectin Chimeras Influences Secretase Processing [PDF]
Amyloid β protein, the major component of the senile plaques in Alzheimer's disease, is generated by secretory and endocytic processing of amyloid precursor protein. Internalized amyloid precursor protein either recycles to the plasma membrane, where α‐secretase resides, or moves to acidic compartment(s) for β‐secretase exposure.

β‐amyloid activates microglia via the TLR/NF‐κB pathway and primes the NLRP3 inflammasome, driving neuroinflammation. β‐asarone counteracts this by activating autophagy, which degrades NLRP3 components and inhibits inflammasome assembly. This reduces IL‐1β maturation, suppresses cytokine release, and alleviates neuronal damage and cognitive deficits in

Amyloid precursor protein (APP) is expressed in a large variety of neural and non-neural cells. The balance between non-pathogenic and pathologic forms of APP processing, mediated by α-secretase and β-secretase respectively, remains a crucial step to ...

Alzheimer's disease (AD) is the most prevalent form of dementia affecting the elderly. Neurodegeneration is caused by the amyloid beta (Aβ) peptide which is generated from the sequential proteolytic cleavage of the Amyloid Precursor Protein (APP) by the ...

Ginsenoside Rg1 (Rg1) from Panax ginseng shows multifunctional health effects. Although oral bioavailability is low and blood–brain barrier (BBB) penetration is limited, delivery systems such as liposomes and nanoparticles may improve exposure. Rg1 reduces inflammation/oxidative stress by inhibiting nuclear factor‐κB (NF‐κB) signaling and reactive ...

Inhibition of amyloid precursor protein secretases reduces recovery after spinal cord injury [PDF]
Amyloid-β (Aβ) is produced through the enzymatic cleavage of amyloid precursor protein (APP) by β (Bace1) and γ-secretases. The accumulation and aggregation of Aβ as amyloid plaques is the hallmark pathology of Alzheimer׳s disease and has been found in other neurological disorders, such as traumatic brain injury and multiple sclerosis.
