Intercompartmental communication in senescence

FEBS Open Bio, EarlyView.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

Folding mechanisms steer the amyloid fibril formation propensity of highly homologous proteins [PDF]

, 2018
Significant advances in the understanding of the molecular determinants of fibrillogenesis can be expected from comparative studies of the aggregation propensities of proteins with highly homologous structures but different folding pathways.

Cleavage of Amyloid-β Precursor Protein and Amyloid-β Precursor-like Protein by BACE 1 [PDF]

Journal of Biological Chemistry, 2004
Site-specific proteolysis of the amyloid-beta precursor protein (APP) by BACE 1 and gamma-secretase, a central event in Alzheimer disease, releases a large secreted extracellular fragment (called APP(S)), peptides of 40-43 residues derived from extracellular and transmembrane sequences (Abeta), and a short intracellular fragment (APP intracellular ...

Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.

LRP1 Has a Predominant Role in Production over Clearance of Aβ in a Mouse Model of Alzheimer's Disease. [PDF]

, 2019
The low-density lipoprotein receptor-related protein-1 (LRP1) has a dual role in the metabolism of the amyloid precursor protein (APP). In cellular models, LRP1 enhances amyloid-β (Aβ) generation via APP internalization and thus its amyloidogenic ...

[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

Herpes simplex virus interferes with amyloid precursor protein processing [PDF]

, 2005
Background The early events underlying Alzheimer's disease (AD) remain uncertain, although environmental factors may be involved. Work in this laboratory has shown that the combination of herpes simplex virus type 1 (HSV1) in brain and carriage of the

Persistent Bilateral [18F]THK5351 and Migrating Unilateral [18F]FDG Uptake in Anti‐LGI1 Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Anti–leucine‐rich glioma‐inactivated 1 encephalitis (LGI1‐E) can cause persistent cognitive deficits, but the mechanisms remain unclear. A 40‐year‐old woman with LGI1‐E presented with subacute cognitive deficits and showed mild left medial temporal lobe (MTL) swelling and fluid‐attenuated inversion recovery (FLAIR) hyperintensity on initial ...

Tetramethylpyrazine Nitrone (TBN) Reduces Amyloid β Deposition in Alzheimer’s Disease Models by Modulating APP Expression, BACE1 Activity, and Autophagy Pathways

Pharmaceuticals
Alzheimer’s disease (AD) is a neurodegenerative disorder associated with age. A wealth of evidence indicates that the amyloid β (Aβ) aggregates result from dyshomeostasis between Aβ production and clearance, which plays a pivotal role in the pathogenesis

MicroRNA regulation of Alzheimer's Amyloid precursor protein expression

Neurobiology of Disease, 2009
Gene dosage effects of Amyloid precursor protein (APP) can cause familial AD. Recent evidence suggest that microRNA (miRNA) pathways, implicated in gene transcriptional control, could be involved in the development of sporadic Alzheimer's disease (AD ...
