Alzheimer's disease (AD) is emerging as the most prevalent and socially disruptive illness of aging populations as more people live long enough to become affected. Although AD is placing a considerable and increasing burden on patients, caregivers and society, it represents the largest unmet medical need in neurology, because it is currently incurable. In the last few years, the amyloid hypothesis, which points to amyloid β-peptide (Aβ) as the initiating factor in AD, had a central role in the development of therapeutic strategies for AD...

Proteolytic cleavage represents a unique and irreversible posttranslational event regulating the function and half-life of many intracellular and extracellular proteins. The metalloproteinase ADAM10 has raised attention since it cleaves an increasing number of protein substrates close to the extracellular membrane leaflet. This "ectodomain shedding" regulates the turnover of a number of transmembrane proteins involved in cell adhesion and receptor signaling. It can initiate intramembrane proteolysis followed by nuclear transport and signaling of the cytoplasmic domain...

BACKGROUND: ADAM10 and ADAM17 are the best characterized members of the ADAM (A Disintegrin and Metalloproteinase) - family of transmembrane proteases. Both are involved diverse physiological and pathophysiological processes. ADAMs are known to be regulated by posttranslational mechanisms. However, emerging evidence indicates that the plasma membrane with its unique dynamic properties may additionally play an important role in controlling sheddase function. SCOPE OF REVIEW: Membrane events that could contribute to regulation of ADAM-function are summarized...

Acid fibroblast growth factor (aFGF) has shown neuroprotection in Alzheimer's disease (AD) models in previous studies, yet its mechanism is still uncertain. Here we report that the efficacy of Tat-haFGF14-154 is markedly increased when loaded cationic liposomes for intranasal delivery are intranasally administered to APP/PS1 mice. Our results demonstrated that liposomal Tat-haFGF14-154 treatment significantly ameliorated behavioral deficits, relieved brain Aβ burden, and increased the expression and activity of disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) in the brain...

A disintegrin and metalloprotease 10 (ADAM10) is a ubiquitously expressed transmembrane protein which is essential for embryonic development through activation of Notch proteins. ADAM10 regulates over 40 other transmembrane proteins and acts as a 'molecular scissor' by removing their extracellular regions. ADAM10 is also a receptor for α-toxin, a major virulence factor of Staphylococcus aureus Owing to the importance of its substrates, ADAM10 is a potential therapeutic target for cancer, neurodegenerative diseases such as Alzheimer's and prion diseases, bacterial infection and inflammatory diseases such as heart attack, stroke and asthma...

The association between ionising radiation (IR) exposure and risk of cardiovascular diseases (CVD) is well documented, but the underlying mechanism is still poorly understood. As atherosclerotic plaques are the most common cause of CVD, we investigated the effects of IR on one of the critical parameters for atherosclerotic plaque formation - endothelium permeability to macromolecules.We used endothelial cells from human coronary artery as a model of the endothelial layer. Our results show that exposure of this endothelial layer to IR increased its permeability to macromolecules of various sizes in a dose-dependent manner...

The Notch signaling pathway, which is activated by cell-cell contact, is a major regulator of cell fate decisions. Mammalian Notch1 is present at the cell surface as a heterodimer of the Notch extracellular domain associated with the transmembrane and intracellular domains. After ligand binding, Notch undergoes proteolysis, releasing the Notch intracellular domain (NICD) that regulates gene expression. We monitored the early steps of activation with biochemical analysis, immunofluorescence analysis, and live-cell imaging of Notch1-expressing cells...

Alzheimer's disease (AD) is the world's most common form of dementia, in which aggregation of amyloid-β (Aβ) is the hallmark. Unfortunately, few medicines have succeeded to completely cure AD. Yangxue Qingnao (YXQN) is a Chinese traditional medicine, and its pharmacological effect is improving cerebral blood flow. In this study, we firstly demonstrated that YXQN reduced AD-like pathology and cognitive impairment in APPswePS1dE9 (APP/PS1) mice with 2 months administration. Our data showed that YXQN substantially ameliorated behavioral defects in 10-month old APP/PS1 mice using Morris Water Maze and Y-maze tests, in which the cognitive ability of YXQN high-dose group approaches to wild type mice...

The recruitment of blood leukocytes across the endothelium to sites of tissue infection is central to inflammation, but also promotes chronic inflammatory diseases. A disintegrin and metalloproteinase 10 (ADAM10) is a ubiquitous transmembrane molecular scissor that is implicated in leukocyte transmigration by proteolytically cleaving its endothelial substrates. These include VE-cadherin, a homotypic adhesion molecule that regulates endothelial barrier function, and transmembrane chemokines CX3CL1 and CXCL16, which have receptors on leukocytes...

HIV-1 enters the CNS soon after peripheral infection and causes chronic neuroinflammation and neuronal damage that leads to cognitive impairment in 40-70% of HIV-infected people. The nonpathogenic cellular isoform of the human prion protein (PrP(c)) is an adhesion molecule constitutively expressed in the CNS. Previously, our laboratory showed that shed PrP(c) (sPrP(c)) is increased in the cerebrospinal fluid of HIV-infected people with cognitive deficits as compared with infected people with no impairment. In this article, we demonstrate that CCL2 and TNF-α, inflammatory mediators that are elevated in the CNS of HIV-infected people, increase shedding of PrP(c) from human astrocytes by increasing the active form of the metalloprotease ADAM10...

The loss of sensory hair cells from the inner ear is a leading cause of hearing and balance disorders. The mammalian ear has a very limited ability to replace lost hair cells, but the inner ears of non-mammalian vertebrates can spontaneously regenerate hair cells after injury. Prior studies have shown that replacement hair cells are derived from epithelial supporting cells and that the differentiation of new hair cells is regulated by the Notch signaling pathway. The present study examined molecular influences on regeneration in the avian utricle, which has a particularly robust regenerative ability...

Alzheimer's disease (AD), the main form of dementia in the elderly, is the most common progressive neurodegenerative disease characterized by rapidly progressive cognitive dysfunction and behavior impairment. AD exhibits a considerable heritability and great advances have been made in approaches to searching the genetic etiology of AD. In AD genetic studies, methods have developed from classic linkage-based and candidate-gene-based association studies to genome-wide association studies (GWAS) and next generation sequencing (NGS)...

BACKGROUND AND OBJECTIVES: Insulin resistance of the brain is a specific form of type2-diabetes mellitus (T2DM) and the active insulin-signaling pathway plays a neuroprotective role against damaging conditions and Alzheimer's progression. The present study identifies the mediated emerging effects of the Nigella sativa oil (NSO) on the memory enhancing process, its anti-oxidative, acetylcholinestrase (AChE) inhibition, anti-brain insulin resistance and anti-amyloidogenic activities. In addition, the possible role of some anti-diabetic drugs in the neuro-protection processes and their effect in combination with NSO and/or the insulin receptor inhibitor IOMe-AG538 were investigated...

The low-density lipoprotein receptor-related protein 1, LRP1, interacts with APP and affects its processing. This is assumed to be mostly caused by the impact of LRP1 on APP endocytosis. More recently, also an interaction of APP and LRP1 early in the secretory pathway was reported whereat retention of LRP1 in the ER leads to decreased APP cell surface levels and in turn, to reduced Aβ secretion. Here, we extended the biochemical and immunocytochemical analyses by showing via live cell imaging analyses in primary neurons that LRP1 and APP are transported only partly in common (one third) but to a higher degree in distinct fast axonal transport vesicles...

Background -Thioredoxin-1 (TRX1), a ubiquitous 12 kDa protein, exerts anti-oxidant and anti-inflammatory effects. In contrast, the truncated form, called TRX80, produced by macrophages induces up-regulation of pro-inflammatory cytokines. TRX80 also promotes the differentiation of mouse peritoneal and human macrophages toward a pro-inflammatory M1 phenotype. Methods -TRX1 and TRX80 plasma levels were determined using specific ELISA. ADAM-17 and ADAM-10 activities were measured using respectively SensoLyte® 520 ADAM10 Activity Assay Kit *Fluorimetric* and InnoZyme™ TACE Activity Kit...

Physiological non-amyloidogenic processing (NAP) of amyloid precursor holoprotein (hAPP) by α-secretases (e.g., ADAM10) extracellularly sheds neurotrophic/neuroprotective soluble (s)APPα and precludes amyloid-β peptides (Aβs) production via β-secretase amyloidogenic processing (AP). Evidence exists that Aβs interact with calcium-sensing receptors (CaSRs) in human astrocytes and neurons, driving the overrelease of toxic Aβ42/Aβ42-os (oligomers), which is completely blocked by CaSR antagonist (calcilytic) NPS 2143...

An enzyme called ADAM10 cleaves a protein found in synaptic membranes, creating a soluble factor that can fuel the growth of brain tumors. Blocking this enzyme shrinks tumors in xenograft models of pediatric glioblastoma and diffuse intrinsic pontine glioma, two brain cancers with few to no effective drug options, researchers reported at the American Academy of Neurology 2017 Annual Meeting.

Recent findings suggest that upregulated a disintegrin and metalloproteinase (ADAM)10 expression participates in the progression of multiple types of cancer. However, the expression pattern and clinicopathological significance of ADAM10, and its potential prognostic role in laryngeal carcinoma remains to be explored. The present study firstly determined the significantly elevated expression status of ADAM10 protein and messenger RNA in laryngeal carcinoma tissues compared with that in adjacent non-tumor tissues by western blotting and reverse transcription-quantitative polymerase chain reaction analysis...

Tetraspanins are a family of transmembrane proteins that form membrane microdomains. They play important roles in migration, adhesion, and other cellular processes. TspanC8, a subfamily of tetraspanins, were found to associate and promote ADAM10 trafficking and cell surface localization. One of its members, Tspan33, is expressed in activated B cells. Using RT-PCR and flow cytometry, we analyzed the pattern of expression of Tspan33 in B cells from healthy donors. We found Tspan33 expression in early and late stages of B cell development...
