  • 功能：
    Functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Interaction between APP molecules on neighboring cells promotes synaptogenesis. Involved in cell mobility and transcription regulation through protein-protein interactions. Can promote transcription activation through binding to APBB1-KAT5 and inhibit Notch signaling through interaction with Numb. Couples to apoptosis-inducing pathways such as those mediated by G(O) and JIP. Inhibits G(o) alpha ATPase activity. Acts as a kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1. By acting as a kinesin I membrane receptor, plays a role in axonal anterograde transport of cargo towards synapes in axons. May be involved in copper homeostasis/oxidative stress through copper ion reduction. Can regulate neurite outgrowth through binding to components of the extracellular matrix such as heparin and collagen I and IV. The splice isoforms that contain the BPTI domain possess protease inhibitor activity. Induces a AGER-dependent pathway that involves activation of p38 MAPK, resulting in internalization of amyloid-beta peptide and leading to mitochondrial dysfunction in cultured cortical neurons. Provides Cu(2+) ions for GPC1 which are required for release of nitric oxide (NO) and subsequent degradation of the heparan sulfate chains on GPC1.; Amyloid-beta peptides are lipophilic metal chelators with metal-reducing activity. Binds transient metals such as copper, zinc and iron. Rat and mouse amyloid-beta peptides bind only weakly transient metals and have little reducing activity due to substitutions of transient metal chelating residues. Amyloid-beta protein 42 may activate mononuclear phagocytes in the brain and elicit inflammatory responses. Promotes both tau aggregation and TPK II-mediated phosphorylation. Also binds GPC1 in lipid rafts.; The gamma-CTF peptides as well as the caspase-cleaved peptides, including C31, are potent enhancers of neuronal apoptosis.; N-APP binds TNFRSF21 triggering caspase activation and degeneration of both neuronal cell bodies (via caspase-3) and axons (via caspase-6).

    1. This study uncovered two clear phases in the life of APP23 mice: developmental and aging. Development displays similarities to young carriers of familial Alzheimer's disease (AD) mutations. All gene expression differences between APP23 and control mice correlate with aging. Age-related expression changes appear exacerbated/accelerated in APP23 mice. PMID: 27838490
    2. These results provide evidence for an emerging role of BAG-1M in the regulation of BACE1 expression and AD pathogenesis and that targeting the BAG-1M-NF-kappaB complex may provide a mechanism for inhibiting Abeta production and plaque formation. PMID: 28502705
    3. Conformational changes in a mouse model of Alzheimer's disease-linked amyloid beta and APP take place before the amyloids plaques can be seen. PMID: 28287086

    8. The concentrations of Abeta (1-42) were also significantly higher in early stage Alzheimer's disease (AD) mice compared with WT mice, however, the levels were markedly lower compared with later stage AD mice, as determined by ELISA. In addition to increased levels of Abeta (1-42) in mice with later stage AD, reduced astrocyte staining was observed compared with WT mice. PMID: 29568933

Increased nuclear translocation of histone deacetylase 4 (HDAC4) in ApoE4 astrocytes, compared with the nonpathogenic ApoE3 allele, suggested a mechanistic basis for transcriptional down-regulation of NHE6. PMID: 29946028
    12. This commentary reviews the role of the Alzheimer amyloid peptide Abeta on basal synaptic transmission, synaptic short-term plasticity, as well as short- and long-term potentiation in transgenic mice, with a special focus on N-terminal truncated Abeta4-42. PMID: 29561816
    13. ADAP KO mice developed glomerular pathology. ADAP KO podocytes lack cell protrusions with actin cytoskeleton forming circumferential stress fibers. PMID: 29192064
    14. Therefore, APP modulates Nav1.6 sodium channels through a Go-coupled JNK pathway, which is dependent on phosphorylation of APP at Thr668. PMID: 28008944
    15. These findings suggest that in the absence of CLU, Abeta clearance shifts to perivascular drainage pathways, resulting in fewer parenchymal plaques but more CAA because of loss of CLU chaperone activity, complicating the potential therapeutic targeting of CLU for AD. PMID: 28701379
    16. Chronic Dyrk1 inhibition reversed cognitive deficits in Alzheimer's disease transgenic mice via reduction of APP and phosphorylated tau pathology. PMID: 28779511
    17. The findings provide a model for initiation of synaptic dysfunction whereby exposure to physiologic levels of amyloid beta for a prolonged period of time causes microstructural changes at the synapse which result in increased transmitter release, failure of synaptic plasticity, and memory loss. PMID: 27581852
    18. The results of the present study substantiate that cGMP has a role in the endocytic pathway of APP and suggest a scenario where the cyclic nucleotide enhances the production of Abeta by favoring the trafficking of APP from the cell cortex to the endolysosomal compartment. PMID: 28789837
    19. Study showed that the APP Osaka mutation has dual effects: it causes a loss-of-function of APP and gain-of-toxic-function of Abeta, though the latter seems to come out only after the former causes GABAergic depletion. Also present OSK-KI mice as a mouse model to replicate the hereditary form of recessive familial Alzheimer's disease. PMID: 28760161
    20. Enhancing mitochondrial proteostasis reduces amyloid-beta proteotoxicity PMID: 29211722
    21. Results show that the duration of UP state, which is a key feature of cortical synaptic integration occurring predominantly during slow-wave sleep, is significantly increased in the prefrontal cortex in the absence of APP. This was accompanied by a specific reduction in the glutamine synthetase and tissue GABA content and sequential upregulation in the levels of GABA-B receptor expression. PMID: 27552836
    22. results support the hypothesis that the miR-132/212 network, including Sirt1 and likely other target genes, contributes to abnormal Abeta metabolism and senile plaque deposition in AD. PMID: 27484949
    23. Activation of CaMKIV by soluble amyloid-beta1-42 impedes trafficking of axonal vesicles and impairs activity-dependent synaptogenesis PMID: 28698220

    25. The cognitive function of APP/PS1 mice was impaired at 10months of age; moreover, the hypermetabolic state identified in various brain regions at 5months of age was also significantly decreased. PMID: 29107091
    26. APP heterozygosity results in greater decreases of cortical APP in Transgenic (Tg) versus non-Tg mice. Mutant huntingtin transgenic mice develop brain iron accumulation as a result of greater suppression of APP levels. Elevated brain iron in Tg mice was associated with a decline in motor endurance consistent with a disease promoting effect of iron in the YAC128 model of human Huntington's Disease. PMID: 28550267
    27. Mass spectrometry analysis of APP intracellular domains revealed differential processing of APP-C83, APP-C89, and APP-C99 by gamma-secretase already at the epsilon-cleavage stage.

PMID: 28591569
    28. Data show that exosomal amyloid precursor protein C-terminal fragments (APP-CTFs) and bis(monoacylglycero)phosphate (BMP) as candidate biomarkers diagnostic of endolysosomal dysfunction associated with neurodegenerative disorders. PMID: 29348617

    30. Conducted in vivo extracellular recording to investigate cholinergic compound action potentials of the superior cervical ganglion (SCG) in APP(-/-) and littermate wild-type (WT) mice; found that APP not only regulates presynaptic activity, but also affects postsynaptic function at cholinergic synapses in SCG; also alpha4beta2 and alpha7 nicotinic acetylcholine receptors are reduced in the absence of APP.

    40. Combining a murine APP-deficient and a human APP-transgenic strain, we were able to analyse the progression of the cortical amyloidosis independent of the murine variant. The lack of endogenous mAPP resulted in accelerated deposition and, thus, increased number of senile plaques and higher levels of aggregated hAbeta. PMID: 28637503
    41. our findings indicate that sortilin is a beneficial protein for the reduction of amyloid pathology in APP/PS1 mice by promoting APP degradation PMID: 29056359
    42. APP levels then decrease progressively as a function of age in close relationship with the gradual normalization of FMRP and hnRNP C levels. PMID: 26048669
    43. a 99-aa C-terminal fragment of APP,C99, in addition to its localization in endosomes, can also be found in mitochondria-associated endoplasmic reticulum (ER) membranes, where it is normally processed rapidly by gamma-secretase. PMID: 29018038

    45. results suggest that PrP(C) recognizes structural features common to both Abeta oligomers and fibril ends and that this interaction could contribute to the neurotoxic effect of Abeta aggregates. PMID: 28842494
    46. Our study provides the first direct evidence that Abeta, an AD-linked factor, is associated to the pathogenesis of ALS and provides molecular clues to understand common aggregation mechanisms in the pathogenesis of neurodegenerative diseases. PMID: 28864422
    47. These data provide evidence that amyloid beta acts to enhance tau pathology by increasing the formation of tau species capable of seeding new aggregates. PMID: 28500862
    48. Although hyperactivity and hypersynchronicity were respectively detected in mice expressing the PS2-N141I or the APP Swedish mutant alone, the increase in cross-frequency coupling specifically characterized the 6-month-old PS2APP mice, just before the surge of the cognitive decline PMID: 27889678
