TOMM40 suppression promotes neuronal cholesterol imbalance and molecular and behavioral phenotypes of Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION While the apolipoprotein E (APOE) ε4 allele is a major risk factor for Alzheimer's disease (AD), the role of translocase of outer mitochondrial membrane 40 (TOMM40)—an adjacent gene involved in mitochondrial protein import—is not known. METHODS Human brain tissue, human induced pluripotent stem cell–derived neurons (iNeurons), and

Endosomal Sorting of Amyloid Precursor Protein‐P‐Selectin Chimeras Influences Secretase Processing [PDF]

Traffic, 2001
Amyloid β protein, the major component of the senile plaques in Alzheimer's disease, is generated by secretory and endocytic processing of amyloid precursor protein. Internalized amyloid precursor protein either recycles to the plasma membrane, where α‐secretase resides, or moves to acidic compartment(s) for β‐secretase exposure.

Contribution of the Endosomal-Lysosomal and Proteasomal Systems in Amyloid-β Precursor Protein Derived Fragments Processing

Frontiers in Cellular Neuroscience, 2018
Aβ peptides, the major components of Alzheimer’s disease (AD) amyloid deposits, are released following sequential cleavages by secretases of its precursor named the amyloid precursor protein (APP).

Cellular functions of gamma-secretase-related proteins [PDF]

, 2006
Amyloid-beta pepticle (A beta) is generated by gamma-secretase, a membrane protein complex with an unusual aspartyl protease activity consisting of the four components presenilin, nicastrin, APH-1 and PEN-2. Presenilin is considered the catalytic subunit

A perspective: PLA2G4A as drug target for vascular inflammation in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract Anti‐amyloid therapies for Alzheimer's disease (AD) modestly slow cognitive decline but carry significant risk of amyloid‐related imaging abnormalities (ARIAs), brain swelling, and hemorrhage, particularly in apolipoprotein E ε4 carriers. Cerebral amyloid angiopathy (CAA) and vascular inflammation drive this vulnerability, highlighting the ...

Further Analyses of the Safety of Verubecestat in the Phase 3 EPOCH Trial of Mild-To-Moderate Alzheimer’s Disease [PDF]

, 2019
Background: Verubecestat, a BACE1 inhibitor that reduces Aβ levels in the cerebrospinal fluid of humans, was not effective in a phase 3 trial (EPOCH) of mild-to-moderate AD and was associated with adverse events.

Human iPSC‐derived GABAergic interneuron transplantation restores circuit balance and cognitive function in an Alzheimer's disease model

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) is characterized by disrupted excitatory–inhibitory (E:I) balance and impaired synaptic function, yet current treatments fail to repair these fundamental circuit impairments. METHODS Human induced pluripotent stem cell‐derived post‐mitotic medial ganglionic eminence‐originated inhibitory neurons (MGE‐pINs)

High resolution imaging study of interactions between the 37 kDa/67 kDa laminin receptor and APP, beta-secretase and gamma-secretase in Alzheimer's disease.

PLoS ONE, 2014
Alzheimer's disease (AD) is the most prevalent form of dementia affecting the elderly. Neurodegeneration is caused by the amyloid beta (Aβ) peptide which is generated from the sequential proteolytic cleavage of the Amyloid Precursor Protein (APP) by the ...

Hypoxic regulation of ion channel function and expression [PDF]

, 2002
Acute hypoxia regulates the activity of specific ion channels in a rapid and reversible manner. Such effects underlie appropriate cellular responses to hypoxia which are designed to initiate cardiorespiratory reflexes and contribute importantly to other ...

AS1842856 Reduces β‐Amyloid Burden via Inhibiting PLA2G4A‐Mediated Lysosomal Dysfunction in APP/PS1 Mice

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
AS1842856 reduces intracellular levels of GSK3α/β by binding to them and promoting their exocytosis. This reduction leads to diminished GSK3β‐mediated activation of NF‐κB, resulting in decreased transcription of PLA2G4A and reduced lysosomal damage. Ultimately, this enhances lysosomal degradation of Aβ, lowering Aβ load in APP/PS1 mice.
