Multifunctionalized Reduced Graphene Oxide Biosensors for Simultaneous Monitoring of Structural Changes in Amyloid-β 40

open access: yesSensors, 2018
Determination of the conformation (monomer, oligomer, or fibril) of amyloid peptide aggregates in the human brain is essential for the diagnosis and treatment of Alzheimer’s disease (AD).

The Protective Role of Carnosic Acid against Beta-Amyloid Toxicity in Rats

open access: yesThe Scientific World Journal, 2013
Oxidative stress is one of the pathological mechanisms responsible for the beta- amyloid cascade associated with Alzheimer’s disease (AD). Previous studies have demonstrated the role of carnosic acid (CA), an effective antioxidant, in combating oxidative

Results of Beta Secretase-Inhibitor Clinical Trials Support Amyloid Precursor Protein-Independent Generation of Beta Amyloid in Sporadic Alzheimer’s Disease

open access: yesMedical Sciences, 2018
The present review analyzes the results of recent clinical trials of β secretase inhibition in sporadic Alzheimer’s disease (SAD), considers the striking dichotomy between successes in tests of β-site Amyloid Precursor Protein-Cleaving ...

The immunotherapy of Alzheimer's disease

open access: yesImmunity & Ageing, 2004
Only a small percentage of patients with Alzheimer's disease benefit from current drug therapy and for only a relatively short time. This is not surprising as the goal of these drugs is to enhance existing cerebral function in Alzheimer patients and not ...

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

open access: yesHeliyon, 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).

Regional distribution of amyloid-Bri deposition and its association with neurofibrillary degeneration in familial British dementia [PDF]

open access: yes, 2001
Familial British dementia (FBD), pathologically characterized by cerebral amyloid angiopathy (CAA), amyloid plaques, and neurofibrillary degeneration, is associated with a stop codon mutation in the BRI gene resulting in the production of an ...

Cerebrospinal Fluid Tau, p-Tau 181 and Amyloid-beta(38/40/42) in Frontotemporal Dementias and Primary Progressive Aphasias [PDF]

open access: yes, 2010
Background/Aims: We determined cerebrospinal fluid (CSF) concentrations of amyloid-beta(A beta)(1-38), A beta(1-40), A beta(1-42), total tau and phospho-tau (p-tau) in order to study their differential expression in frontotemporal dementia (FTD, n = 25 ...

Melatonin-mediated calcineurin inactivation attenuates amyloid beta-induced apoptosis

open access: yesIBRO Neuroscience Reports
Alzheimer’s disease (AD) is the most common age-related progressive neurodegenerative disorder. The accumulation of amyloid beta-peptide is a neuropathological marker of AD.

The Beta Amyloid Dysfunction (BAD) Hypothesis for Alzheimer’s Disease

open access: yesFrontiers in Neuroscience, 2019
Beta amyloid, Aβ 1–42, originally named as Amyloid A4 protein, is one of the most investigated peptides in neuroscience and has attracted substantial interest since its discovery as the main insoluble fibril-type protein in cerebrovascular amyloid ...

The novel amyloid-beta peptide aptamer inhibits intracellular amyloid-beta peptide toxicity

open access: yesNeural Regeneration Research, 2013
Amyloid β peptide binding alcohol dehydrogenase (ABAD) decoy peptide (DP) can competitively antagonize binding of amyloid β peptide to ABAD and inhibit the cytotoxic effects of amyloid β peptide. Based on peptide aptamers, the present study inserted ABAD-DP into the disulfide bond of human thioredoxin (TRX) using molecular cloning technique to ...
