In Silico Structure‐Guided Design of Peptide Candidates Targeting γ‐Secretase Subunit Assembly
ABSTRACT The γ‐secretase complex is a membrane‐embedded protease essential for intramembrane cleavage of substrates such as Notch receptors and the amyloid precursor protein (APP), processes central to cancer progression and Alzheimer's disease (AD) pathology.

Protein Topology of Presenilin 1 [PDF]
Mutations in a gene encoding a multitransmembrane protein, termed presenilin 1 (PS1), are causative in the majority of early-onset cases of AD. To determine the topology of PS1, we utilized two strategies: first, we tested whether putative transmembranes are sufficient to export a protease-sensitive substrate across a lipid bilayer; and second, we ...

Identification of transcription factor binding sites in promoter databases [PDF]
Transcription factors (TFs) are the proteins which regulates the expression of their target genes either in a positive or negative manner. TFs realize this task by binding to a specific DNA sequence contained in promoter regions, via their DNA binding ...

Neuritic plaques increase in the intermediate stage of Alzheimer's neuropathological change. The intermediate stage of Alzheimer's disease was investigated by transcriptomics and immunohistochemistry. This revealed that inflammasome sensors NLRP1, NLRP3, and AIM2 oligomerize with ASC speck to form the inflammasome complex and initiate the downstream ...

The presenilins and Alzheimer's disease [PDF]
The presenilin 1 and presenilin 2 genes have been identified as pathogenic loci involved in the majority of early onset, autosomal dominant Alzheimer's disease. A series of (predominantly) missense mutations have been identified in the two genes which lead to disease. The presenilins are probably eight transmembrane domain proteins with both termini in

Association of active γ-secretase complex with lipid rafts
Cholesterol has been implicated in the pathogenesis of Alzheimer's disease (AD). Although the underlying mechanisms are not yet clear, several studies have provided evidence for the involvement of cholesterol-rich lipid rafts in the production of amyloid

Manipulation of lipid rafts in neuronal cells [PDF]
Lipid rafts are specialized plasma membrane micro-domains highly enriched in cholesterol, sphingolipids and glycosylphosphatidylinositol (GPI) anchored proteins.

Notch signalling is an evolutionarily conserved signalling pathway that directs cell growth and differentiation across multiple tissue types, and its regulation must be controlled across the lifespan. Aberrant Notch signalling due to genetic mutations that occur within the negative regulatory region of the Notch 1 gene is linked to the development of ...

TREM2-dependent effects on microglia in Alzheimer\u27s Disease [PDF]
Alzheimer’s disease (AD) is a late-onset dementia characterized by the deposition of amyloid plaques and formation of neurofibrillary tangles (NFTs) which lead to neuronal loss and cognitive deficits.

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...
