The ε4 allele of the apolipoprotein E (APOE) gene is a prominent risk factor for Alzheimer’s disease (AD), but its implication in other dementias is less well studied. Read & Research Alzheimer’s More

Inheritance of the ε4 allele of apolipoprotein E (APOE) increases a person’s risk of developing both Alzheimer’s disease (AD) and Lewy body dementia (LBD), yet the underlying mechanisms behind this risk are incompletely understood. The recent identification of reduced APOE DNA methylation in AD postmortem brains prompted this study to Read & Research Alzheimer’s More

The TOMM40 poly-T is a polymorphism in intron 6 of the TOMM40 gene, which is adjacent to and in linkage disequilibrium with APOE. Roses et al identified the association between the length of TOMM40 poly-T with the risk and age of onset of late-onset Alzheimer’s disease (LOAD). Following the original discovery, Read & Research Alzheimer’s More

Levels of amyloid β peptide 42 (Aβ42), total tau, and phosphorylated tau-181 are well-established cerebrospinal fluid (CSF) biomarkers of Alzheimer’s disease, but variability in manual plate-based assays has limited their use. We examined the relationship between CSF biomarkers, as measured by a novel automated immunoassay platform, and amyloid positron emission Read & Research Alzheimer’s More

The synaptic vesicle cycle (SVC) holds center stage in the biology of presynaptic terminals. Through recurrent exocytosis and endocytosis, it facilitates a sequence of events enabling chemical neurotransmission between functionally related neurons. As a fundamental process that links the interior of nerve cells with their environment, the SVC is also Read & Research Alzheimer’s More

Neuroinflammation is now considered to be of pathophysiologic significance in Alzheimer’s disease and other neurodegenerative conditions. Nonetheless, there is no consensus as to what inflammatory mechanisms need to be combated (or facilitated), how therapies for them should be applied, or when they might be efficacious.

The objective of this study was to evaluate amyloid β (Aβ) deposition patterns in different groups of cerebral β amyloidosis: (1) nondemented with amyloid precursor protein overproduction (Down syndrome); (2) nondemented with abnormal processing of amyloid precursor protein (preclinical autosomal dominant Alzheimer disease); (3) presumed alteration in Aβ clearance with Read & Research Alzheimer’s More
