The Large Ectodomain of APP Prevents APP from being Directly Cleaved by γ-Secretase
Frontiers in Bioscience-LandmarkBackground: Alzheimer’s disease (AD) is characterized by the deposition of amyloid-β peptide (Aβ) in the brain. Aβ is produced by sequential β- and γ-secretase cleavages of amyloid precursor protein (APP).

A noncanonical role for Jagged1 in endothelial mechanotransduction
The FEBS Journal, EarlyView.This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.

Presenilin-dependent intramembrane cleavage of ephrin-B1
Molecular Neurodegeneration, 2006 Background Presenilin-dependent γ-secretase cleavage of several transmembrane proteins, including amyloid-β precursor protein and Notch, mediates the intramembrane proteolysis to liberate their intracellular domains that are involved in cellular ...

Optimization of photobiomodulation therapy for spinal cord injury: A review
Photochemistry and Photobiology, EarlyView.Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Association of active γ-secretase complex with lipid rafts
Journal of Lipid Research, 2005 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

Human Cyclophilins—An Emerging Class of Drug Targets
Medicinal Research Reviews, Volume 46, Issue 2, Page 475-512, March 2026.ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Novel NOTCH3 alteration expanding the molecular spectrum of pericytic tumours: report of two cases
Histopathology, Volume 88, Issue 4, Page 922-927, March 2026.Introduction Myofibromas are part of the pericytic tumour family, which includes myopericytomas, glomus tumours and angioleiomyomas. While they typically display benign behaviour when arising in the skin and subcutaneous tissues of the head and neck, rare aggressive variants have been reported, particularly those with visceral or intracranial ...

Journal of Cellular and Molecular Medicine, Volume 30, Issue 5, March 2026.ABSTRACT Alzheimer's disease (AD) is a highly complex and multifactorial disorder in which oxidative stress acts as a key amplifying mechanism in the disease progression. Lipofuscin‐like pigments (LFP), end products of lipid peroxidation, reflect oxidative damage and are capable of crossing the blood–brain barrier into the circulation.
