Structural basis for matrix metalloproteinase-2 (MMP-2)-selective inhibitory action of β-amyloid precursor protein-derived inhibitor.
Unlike other synthetic or physiological inhibitors for matrix metalloproteinases (MMPs), the β-amyloid precursor protein-derived inhibitory peptide (APP-IP) having an ISYGNDALMP sequence has a high selectivity toward MMP-2. Our previous study identified amino acid residues of MMP-2 essential for its selective inhibition by APP-IP and demonstrated that the N to C direction of the decapeptide inh...
متن کاملβ-amyloid precursor protein-deficient mice show reactive gliosis and decreased locomotor activity
In several pedigrees of early onset familial Alzheimer's disease (FAD), point mutations in the beta-amyloid precursor protein (APP) gene are genetically linked to the disease. This finding implicates APP in the pathogenesis of Alzheimer's disease in these individuals. To understand the in vivo function of APP and its processing, we have generated an APP-null mutation in mice. Homozygous APP-def...
متن کاملLysosomal NEU1 deficiency affects Amyloid Precursor Protein levels and amyloid-β secretion via deregulated lysosomal exocytosis
Alzheimer's disease (AD) belongs to a category of adult neurodegenerative conditions, which are associated with intracellular and extracellular accumulation of neurotoxic protein aggregates. Understanding how these aggregates are formed, secreted and propagated by neurons has been the subject of intensive research, but so far no preventive or curative therapy for AD is available, and clinical t...
متن کاملIncreased extracellular amyloid deposition and neurodegeneration in human amyloid precursor protein transgenic mice deficient in receptor-associated protein.
The low-density lipoprotein receptor-related protein (LRP) is an abundant neuronal cell surface receptor that regulates amyloid beta-protein (Abeta) trafficking into the cell. Specifically, LRP binds secreted Abeta complexes and mediates its degradation. Previously, we have shown in vitro that the uptake of Abeta mediated by LRP is protective and that blocking this receptor significantly enhanc...
متن کاملExpression of Matrix Metalloproteinase-2 and -9 in Meningioma
Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis.  Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma.  Materials & Me...
