O-glycosylated peptides curtail the aggregation and toxicity of human islet amyloid polypeptide [PDF]

Communications Biology
A key pathogenetic pathway of type 2 diabetes (T2D) is pancreatic beta cell failure, losing their capability of producing insulin and regulating blood glucose.

DHA supplemented in peptamen diet offers no advantage in pathways to amyloidosis: is it time to evaluate composite lipid diet? [PDF]

PLoS ONE, 2011
Numerous reports have documented the beneficial effects of dietary docosahexaenoic acid (DHA) on beta-amyloid production and Alzheimer's disease (AD).

Engineering neprilysin activity and specificity to create a novel therapeutic for Alzheimer's disease. [PDF]

PLoS ONE, 2014
Neprilysin is a transmembrane zinc metallopeptidase that degrades a wide range of peptide substrates. It has received attention as a potential therapy for Alzheimer's disease due to its ability to degrade the peptide amyloid beta.

Western Agarose Native GeELution (WANGEL) with beta-amyloid and tau: Novel method to elute proteins or peptides using native agarose gels followed by Lumipulse assay

MethodsX, 2022
Alzheimer´s disease is characterized by hyperphosphorylated tau neurofibrillary tangles and beta-amyloid plaques. Both molecules can be easily measured in human fluids or tissue extracts by immunoassays.

The orphan drug dichloroacetate reduces amyloid beta-peptide production whilst promoting non-amyloidogenic proteolysis of the amyloid precursor protein.

PLoS ONE, 2022
The amyloid cascade hypothesis proposes that excessive accumulation of amyloid beta-peptides is the initiating event in Alzheimer's disease. These neurotoxic peptides are generated from the amyloid precursor protein via sequential cleavage by β- and γ ...

Early Treatment Critical: Bexarotene Reduces Amyloid-Beta Burden In Silico. [PDF]

PLoS ONE, 2016
Amyloid-beta peptides have long been implicated in the pathology of Alzheimer's disease. Bexarotene, a drug approved by the U.S. Food and Drug Administration for treating a class of non-Hodgkin's lymphoma, has been reported to facilitate the removal of ...

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.
