A novel presenilin 1 mutation (L174M) in a large Cuban family with early onset Alzheimer disease. [PDF]

open access: yes, 2002
We studied a Cuban family with presenile dementia (autosomal dominant) consisting of 281 members within six generations, the proband descended from a Spanish founder. Mean age at onset was 59 years of age.

Alzheimer's presenilin 1 causes chromosome missegregation and aneuploidy [PDF]

open access: yesNeurobiology of Aging, 2008
Mutations in the presenilin 1 gene cause most early onset familial Alzheimer's disease (FAD). Here, we report that a defect in the cell cycle - improper chromosome segregation - can be caused by abnormal presenilin function and therefore may contribute to AD pathogenesis. Specifically we find that either over-expression or FAD mutation in presenilin 1 (

GPND‐AI NULISA: A 15‐Protein AI classifier for diagnosis and co‐pathology profiling across neurodegenerative diseases

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Accurate clinical diagnosis of neurodegenerative diseases remains challenging, particularly when individuals have mixed pathologies. We implemented the generalizable protein‐based neurodegenerative disease artificial intelligence (GPND‐AI) classifier using the NUcleic acid‐Linked Immuno‐Sandwich Assay (NULISA) central nervous ...

Bidirectional regulation of Aβ levels by Presenilin 1 [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance Alzheimer’s disease is the most common neurodegenerative disorder, affecting more than 5 million people in the United States. Multiple lines of evidence suggest that the accumulation of toxic oligomers and aggregates of β-amyloid (Aβ) peptide are the primary causes of neurodegeneration.

Cloning of the Presenilin 2 cDNA and Its Distribution in Brain of the Primate,Microcebus murinus: Coexpression with βAPP and Tau Proteins

open access: yesNeurobiology of Disease, 1998
A 1340-bp cDNA fragment encoding the lemurian presenilin 2 protein (PS2) was isolated from aMicrocebus murinusbrain cDNA library by PCR using oligonucleotide primers based on the nucleotide sequence of the human gene.

rTCT: Rodent Triangle Completion Task to Facilitate Reverse Translational Study of Path Integration

open access: yesHippocampus, Volume 36, Issue 3, May 2026.
ABSTRACT Path integration is navigation in the absence of environmental landmarks and is a primary cognitive mechanism underlying spatial memory. Path integration performance is primarily assessed in humans using the Triangle Completion Task (TCT). In humans, TCT has shown promise for the early diagnosis of Alzheimer's disease.

Functions of p120ctn isoforms in cell-cell adhesion and intracellular signaling [PDF]

open access: yes, 2012
The functions of many organs depend on the generation of an epithelium. The transition from a set of loosely connected nonpolarized cells to organized sheets of closely associated polarized epithelial cells requires the assembly of specialized cell ...

The γ-secretase complex: from structure to function

open access: yesFrontiers in Cellular Neuroscience, 2014
One of the most critical pathological features of Alzheimer’s disease (AD) is the accumulation of β-amyloid (Aβ) peptides that form extracellular senile plaques in the brain. Aβ is derived from β-amyloid precursor protein through sequential cleavage by β-

Quality control of protein import into mammalian mitochondria

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Mitochondrial function depends on the continuous import of hundreds of nuclear‐encoded proteins. Targeting and translocation of mitochondrial proteins is a multistep process that is inherently vulnerable to defects in cytosolic quality control systems as well as perturbations in mitochondrial protein import machinery and organelle function ...

Successful object encoding induces increased directed connectivity in presymptomatic early-onset Alzheimer's disease [PDF]

open access: yes, 2017
Background: Recent studies report increases in neural activity in brain regions critical to episodic memory at preclinical stages of Alzheimer’s disease (AD).
