sorLA (sorting protein-related receptor) is a type-1 membrane protein of unknown function that expressed in neurons. Its homology to sorting receptors shuttle between the plasma membrane, endosomes, and Golgi suggests related neuronal trafficking processes. Because expression reduced brain patients with Alzheimer's disease (AD), we tested involvement this receptor intracellular transport processing amyloid precursor (APP) β-peptide (Aβ), principal component senile plaques. We demonstrate...

sorLA is a sorting receptor for amyloid precursor protein (APP) genetically linked to Alzheimer's disease (AD). Retromer, an adaptor complex in the endosome-to-Golgi retrieval pathway, has been implicated APP transport because retromer deficiency leads aberrant and processing levels of proteins are altered AD. Here we report that functionally interact neurons control trafficking amyloidogenic APP. We have identified sequence (FANSHY) cytoplasmic domain recognized by VPS26 subunit complex....

Loss of the Sortilin-related receptor 1 (SORL1) gene seems to act as a causal event for Alzheimer's disease (AD). Recent studies have established that loss SORL1, well mutations in autosomal dominant AD genes APP and PSEN1/2, pathogenically converge by swelling early endosomes, AD's cytopathological hallmark. Acting together with retromer trafficking complex, SORL1 has been shown regulate recycling amyloid precursor protein (APP) out endosome, contributing endosomal misprocessing. We...

Megalin is a low-density lipoprotein receptor-related protein (LRP2)expressed in the neuroepithelium and yolk sac of early embryo. Absence megalin expression knockout mice results holoprosencephaly,indicating an essential yet unidentified function forebrain development.

SorLA has been recognized as a novel sorting receptor that regulates trafficking and processing of the amyloid precursor protein (APP) represents significant risk factor for sporadic Alzheimer disease. Here, we investigated cellular mechanisms control intracellular sorLA their relevance APP processing. We demonstrate acts retention in trans-Golgi compartments/trans-Golgi network, preventing release into regular pathways. Proper localization activity are dependent on functional interaction...

sorLA is a recently identified neuronal receptor for amyloid precursor protein (APP) that known to interact with APP and affect its intracellular transport processing. Decreased levels of in the brain Alzheimer's disease (AD) patients elevated amyloid-β peptide (Aβ) sorLA-deficient mice point importance this neurodegenerative disorder. We analyzed cleavage an APP-shedding assay found both and, surprisingly, tail construct inhibited β-site APP-cleaving enzyme (BACE)-dependent manner. In line...

SorLA/LR11-mediated binding results sequestration APP Golgi protection from into amyloid-β peptide (Aβ), principal component senile plaques Alzheimer's disease (AD). To gain insight molecular mechanisms governing sorLA interaction, we have dissected respective interacting domains. Using fluorescence resonance energy transfer (FRET) based assay proximity,...

Abstract The human epidermal growth factor receptor 2 (HER2) is an oncogene targeted by several kinase inhibitors and therapeutic antibodies. While the endosomal trafficking of many other tyrosine kinases known to regulate their oncogenic signalling, prevailing view on HER2 that this predominantly retained cell surface.

Whether or how the pathogenic disruptions in endosomal trafficking observed Alzheimer's disease (AD) are linked to its anatomical vulnerability remain unknown. Here, we began addressing these questions by showing that neurons enriched with a second retromer core, organized around VPS26b, differentially dedicated recycling. Next, imaging mouse models, show trans-entorhinal cortex, region most vulnerable AD, is susceptible VPS26b depletion—a finding validated electrophysiology,...

The established causal genes in Alzheimer's disease (AD), APP, PSEN1, and PSEN2, are functionally characterized using biomarkers, capturing an vivo profile reflecting the disease's initial preclinical phase. Mutations SORL1, encoding endosome recycling receptor SORLA, found 2%–3% of individuals with early-onset AD, SORL1 haploinsufficiency appears to be for AD. To test whether can function as AD gene, we use CRISPR-Cas9-based gene editing develop a model Göttingen minipigs, taking advantage...
