Ammonium Sulfate and Ultrafine Particles Affect Early Onset of Alzheimer’s Disease

Chemical Engineering Transactions, 2021
Recent environmental studies have shown the impact of air quality on human health and in particular, toxicological effect of particulate matter (PM) and ultrafine particles (UFPs) on progression of neurodegenerative diseases.

Decreased Deposition of Beta-Amyloid 1-38 and Increased Deposition of Beta-Amyloid 1-42 in Brain Tissue of Presenilin-1 E280A Familial Alzheimer’s Disease Patients

Frontiers in Aging Neuroscience, 2020
Familial Alzheimer’s Disease (FAD) caused by Presenilin-1 (PS1) mutations is characterized by early onset, cognitive impairment, and dementia. Impaired gamma secretase function favors production of longer beta-amyloid species in PS1 FAD.

Astrocytic Redox Remodeling by Amyloid Beta Peptide [PDF]

Antioxidants & Redox Signaling, 2011
Astrocytes are critical for neuronal redox homeostasis providing them with cysteine needed for glutathione synthesis. In this study, we demonstrate that the astrocytic redox response signature provoked by amyloid beta (Aβ) is distinct from that of a general oxidant (tertiary-butylhydroperoxide [t-BuOOH]).

Casuarictin: A new herbal drug molecule for Alzheimer's disease as inhibitor of presenilin stabilization factor like protein

Heliyon, 2020
Alzheimer's disease is a progressive neurodegenerative disorder. In this disease neurodegeneration occurs due to deposition of aggregated amyloid-beta plaques and neurofibrillary tangles (hyperphosphorylated tau proteins).

Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]

, 2009
The cause(s) of sporadic Alzheimer's disease (sAD) are complex and currently poorly understood. They likely result from a combination of genetic, environmental, proteomic and lipidomic factors that crucially occur only in the aged brain.

Contributions of Mass Spectrometry to the Identification of Low Molecular Weight Molecules Able to Reduce the Toxicity of Amyloid-β Peptide to Cell Cultures and Transgenic Mouse Models of Alzheimer’s Disease

Molecules, 2019
Alzheimer’s Disease affects approximately 33 million people worldwide and is characterized by progressive loss of memory at the cognitive level. The formation of toxic amyloid oligomers, extracellular amyloid plaques and amyloid angiopathy in brain

Insight into the structure of amyloid fibrils from the analysis of globular proteins. [PDF]

PLoS Computational Biology, 2006
The conversion from soluble states into cross-beta fibrillar aggregates is a property shared by many different proteins and peptides and was hence conjectured to be a generic feature of polypeptide chains.

Oxidation destabilizes toxic amyloid beta peptide aggregation [PDF]

Scientific Reports, 2019
AbstractThe aggregation of insoluble amyloid beta (Aβ) peptides in the brain is known to trigger the onset of neurodegenerative diseases, such as Alzheimer’s disease. In spite of the massive number of investigations, the underlying mechanisms to destabilize the Aβ aggregates are still poorly understood. Some studies indicate the importance of oxidation
