10.1073/pnas.0905390106 | 109,109,936 | Formation of lasting memories is believed to rely on structural alterations at the synaptic level. We had found that increased neuronal activity down-regulates Nogo receptor-1 (NgR1) in brain regions linked to memory formation and storage, and postulated this to be required for formation of lasting memories. We now sho... | 10.1038/nrn2936 | The first demonstration that NgR is linked to specific aspects of memory in vivo |
10.1126/science.1128657 | 107,254,070 | Analogous to learning and memory storage, long-term potentiation (LTP) is divided into induction and maintenance phases. Testing the hypothesis that the mechanism of LTP maintenance stores information requires reversing this mechanism in vivo and finding out whether long-term stored information is lost. This was not pr... | 10.1038/nrn2590 | This paper identified PKMζ as the only molecule currently known to maintain LTM. |
10.1126/science.1095760 | 104,411,637 | The idea that new memories undergo a time-dependent consolidation process after acquisition has received considerable experimental support. More controversial has been the demonstration that established memories, once recalled, become labile and sensitive to disruption, requiring “reconsolidation” to become permanent. ... | 10.1038/nrn2590 | This paper showed that the mechanisms that mediate consolidation and reconsolidation can be doubly dissociated, suggesting that the differences between consolidation and reconsolidation cannot be explained by use of asymmetric protocols. |
10.1126/science.1150541 | 20,797,361 | Reactivated memory undergoes a rebuilding process that depends on de novo protein synthesis. This suggests that retrieval is dynamic and serves to incorporate new information into preexisting memories. However, little is known about whether or not protein degradation is involved in the reorganization of retrieved memor... | 10.1038/nrn2590 | This paper showed that proteins must be degraded in order to transform a reactivated memory from a fixed to a labile state, suggesting that after reactivation degraded proteins need to be replaced through protein synthesis or else the reactivated memory cannot be re-stabilized. |
10.1126/science.160.3827.554 | 61,009,793 | Rats had a memory loss of a fear response when they received an electroconvulsive shock 24 hours after the fear-conditioning trial and preceded by a brief presentation of the conditioned stimulus. No such loss occurred when the conditioned stimulus was not presented. The memory loss in animals given electroconvulsive s... | 10.1038/nrn2590 | This seminal paper provided the first description of the reconsolidation phenomenon but, for historical reasons, reconsolidation remained outside the mainstream literature until 2000. |
10.1523/jneurosci.2049-06.2006 | 123,584,626 | It has been reported that consolidated memories can return to a labile state when reactivated and undergo a process of re-storage, termed reconsolidation, required for later recall. We investigated memory for a nonassociative learning task (habituation) and found that memory for this task also undergoes reconsolidation... | 10.1038/nrn2590 | This paper showed that blocking reconsolidation in nematodes reverses the molecular correlates of LTM to those of naive animals. |
10.1126/science.1086881 | 85,551,457 | In memory consolidation, the memory trace stabilizes and becomes resistant to certain amnesic agents. The textbook account is that for any memorized item, consolidation starts and ends just once. However, evidence has accumulated that upon activation in retrieval, the trace may reconsolidate. Whereas some authors repor... | 10.1038/nrn2590 | This elegant study showed in two different species that consolidation of extinction learning for a memory could inhibit reconsolidation for this memory. |
10.1101/lm.1022308 | 39,412,309 | Understanding the dynamics of memory change is one of the current challenges facing cognitive neuroscience. Recent animal work on memory reconsolidation shows that memories can be altered long after acquisition. When reactivated, memories can be modified and require a restabilization (reconsolidation) process. We recen... | 10.1038/nrn2590 | This paper demonstrated in humans that episodic memory reconsolidation depends on re-exposure to the spatial context in which the original learning occurred, suggesting that the spatial context is crucial for inducing reconsolidation in human episodic memory. |
10.1084/jem.20110039 | 80,449,560 | Apicomplexa are important pathogens that include the causative agents of malaria, toxoplasmosis, and cryptosporidiosis. Apicomplexan parasites contain a relict chloroplast, the apicoplast. The apicoplast is indispensable and an attractive drug target. The apicoplast is home to a 1-deoxy-d-xylulose-5-phosphate (DOXP) pa... | 10.1038/nrmicro3139 | These authors demonstrated that the insensitivity of T. gondii to fosmidomycin is caused by non-internalization of the drug and that expression of a bacterial GlpT allows fosmidomycin penetration and activity. |
10.1083/jcb.124.4.449 | 41,740,586 | This work describes two unusual features of membrane development in a eukaryotic cell. (a) The induction of an extensive network of tubovesicular membranes by the malaria parasite Plasmodium falciparum in the cytoplasm of the mature erythrocyte, and its visualization with two ceramide analogues C5-DMB-ceramide and C6-N... | 10.1038/nrmicro3139 | These authors show that P. falciparum blood forms elaborate a TVN derived from the parasitophorous vacuole membrane by exporting their own sphingomyelin synthase into the host cell, resulting in the local production of sphingolipids in the network. |
10.1091/mbc.e12-11-0827 | 99,627,713 | The obligate intracellular protozoan Toxoplasma gondii actively invades mammalian cells and, upon entry, forms its own membrane-bound compartment, named the parasitophorous vacuole (PV). Within the PV, the parasite replicates and scavenges nutrients, including lipids, from host organelles. Although T. gondii can synthe... | 10.1038/nrmicro3139 | This study shows that although T. gondii can synthesize sphingolipids de novo , it also scavenges these lipids from the host Golgi apparatus by subverting the structure and functions of this organelle. |
10.1083/jcb.112.2.267 | 60,548,758 | Several intraerythrocytic growth cycles of Plasmodium falciparum could be achieved in vitro using a serum free medium supplemented only with a human high density lipoprotein (HDL) fraction (d = 1.063-1.210). The parasitemia obtained was similar to that in standard culture medium containing human serum. The parasite dev... | 10.1038/nrmicro3139 | This study details how plasma HDL particles support the growth of P. falciparum blood forms by supplying essential lipids, including cholesterol, to the parasite. |
10.1111/j.1600-0854.2012.01398.x | 82,012,020 | The obligate intracellular liver stage of the Plasmodium parasite represents a bottleneck in the parasite life cycle and remains a promising target for therapeutic intervention. During this stage, parasites undergo dramatic morphological changes and achieve one of the fastest replication rates among eukaryotic species.... | 10.1038/nrmicro3139 | This paper shows that Plasmodium berghei liver forms reroute host endocytic structures to the parasitophorous vacuole and use the contents of these organelles as a source of nutrients derived from the medium. |
10.1083/jcb.149.1.167 | 38,903,492 | The obligate intracellular protozoan Toxoplasma gondii resides within a specialized parasitophorous vacuole (PV), isolated from host vesicular traffic. In this study, the origin of parasite cholesterol was investigated. T. gondii cannot synthesize sterols via the mevalonate pathway. Host cholesterol biosynthesis remain... | 10.1038/nrmicro3139 | This study shows that T. gondii is auxotrophic for LDL-derived cholesterol and that interference with LDL endocytosis in the host cell reduces parasite replication. |
10.1111/mmi.12142 | 124,881,408 | Summary Lipid bodies are eukaryotic structures for temporary storage of neutral lipids such as acylglycerols and steryl esters. Fatty acyl‐ CoA and cholesterol are two substrates for cholesteryl ester ( CE ) synthesis via the ACAT reaction. The intracellular parasite T oxoplasma gondii is incapable of sterol synthesis ... | 10.1038/nrmicro3139 | This study shows that T. gondii expresses two ACAT enzymes involved in the storage of cholesterol and that the parasite is particularly vulnerable to ACAT inhibitors. |
10.1146/annurev-med-052209-100430 | 82,879,883 | The brain is the key organ of stress processes. It determines what individuals will experience as stressful, it orchestrates how individuals will cope with stressful experiences, and it changes both functionally and structurally as a result of stressful experiences. Within the brain, a distributed, dynamic, and plastic... | 10.1038/nrn3138 | A recent overview of plasticity of the brain based on animal model studies and human brain research. The overview is based on the conceptual model of allostasis and allostatic load (see reference 3), in which the brain is the central organ of stress and adaptation and regulates and responds to stress hormones and other... |
10.1073/pnas.0507572102 | 42,610,585 | The adrenal hormone corticosterone transcriptionally regulates responsive genes in the rodent hippocampus through nuclear mineralocorticoid and glucocorticoid receptors. Via this genomic pathway the hormone alters properties of hippocampal cells slowly and for a prolonged period. Here we report that corticosterone also... | 10.1038/nrn3138 | This study used patch-clamp recordings to show that applying corticosterone onto hippocampal slices rapidly and reversibly enhances glutamate release and transmission through a non-genomic pathway involving membrane-located mineralocorticoid receptors. |
10.1126/science.1190287 | 104,341,626 | Antidepressant Action of Ketamine In contrast to the weeks or months of treatment required for standard antidepressant medication, ketamine administration produces an antidepressant response within 4 to 6 hours in depressed patients. What lies behind the rapid actions of ketamine? Li et al. (p. 959 ; see the Perspectiv... | 10.1038/nrn3138 | This study demonstrates AMPAR-mediated effects of NMDAR antagonists on synaptic plasticity and behaviour. The paper provides strong evidence to suggest that the antidepressant and anti-stress effects of NMDAR antagonists such as ketamine are, at least in part, mediated by increased excitation of postsynaptic AMPARs. |
10.1073/pnas.89.9.3830 | 875,141 | The recently characterized corticosteroid receptor on amphibian neuronal membranes appears to mediate rapid, stress-induced changes in male reproductive behaviors. Because the transduction mechanisms associated with this receptor are unknown, we performed radioligand binding studies to determine whether this steroid re... | 10.1038/nrn3138 | A key paper showing G-protein-like glucocorticoid receptors in the brain of a newt, Taricha granulosa , which led to the finding of rapid glucocorticoid signalling for the endocannabinoid systems summarized in reference 201. However, recent work (reference 209) showing Ru486 antagonism in the glucocorticoid regulation ... |
10.1126/science.1071184 | 124,251,950 | Harvesting light to produce energy and oxygen (photosynthesis) is the signature of all land plants. This ability was co-opted from a precocious and ancient form of life known as cyanobacteria. Today these bacteria, as well as microscopic algae, supply oxygen to the atmosphere and churn out fixed nitrogen in Earth's vas... | 10.1038/nrmicro2778 | This concept paper outlines the interconnectedness between atmospheric transformation and microbial metabolism now and throughout evolutionary time. |
10.1146/annurev.marine.010908.163855 | 123,187,115 | Ocean warming and increased stratification of the upper ocean caused by global climate change will likely lead to declines in dissolved O 2 in the ocean interior (ocean deoxygenation) with implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitat. Ocean models predict declines of 1 to 7%... | 10.1038/nrmicro2778 | This paper reviews the evidence for global oxygen loss in the oceans over the past 50 years and discusses potential consequences of continued deoxygenation on the ecology and biogeochemistry of marine ecosystems. |
10.1126/science.1156401 | 20,845,774 | Dead zones in the coastal oceans have spread exponentially since the 1960s and have serious consequences for ecosystem functioning. The formation of dead zones has been exacerbated by the increase in primary production and consequent worldwide coastal eutrophication fueled by riverine runoff of fertilizers and the burn... | 10.1038/nrmicro2778 | This influential concept article describes the ecological consequences of episodic or prolonged oxygen starvation on coastal marine ecosystems. |
10.1126/science.1196889 | 104,217,097 | Cryptic Sulfur Cycling Aerobic bacteria and ocean circulation patterns control the formation and distribution of oxygen-minimum zones at moderate depth in the oceans. These habitats host microorganisms that thrive on other metabolic substrates in the absence of oxygen—most commonly, metabolizing thermodynamically favor... | 10.1038/nrmicro2778 | This paper provides the first report of SO 4 2− reduction and concomitant sulphide oxidation in the ETSP OMZ. |
10.1126/science.1203690 | 124,085,094 | Recent studies suggest that unidentified prokaryotes fix inorganic carbon at globally significant rates in the immense dark ocean. Using single-cell sorting and whole-genome amplification of prokaryotes from two subtropical gyres, we obtained genomic DNA from 738 cells representing most cosmopolitan lineages. Multiple ... | 10.1038/nrmicro2778 | This paper reveals the hidden metabolic powers of Arctic96BD-19 and SAR324 bacteria using single-cell genomics techniques. |
10.1111/j.1462-2920.2010.02400.x | 62,314,448 | Summary Simultaneous characterization of taxonomic composition, metabolic gene content and gene expression in marine oxygen minimum zones (OMZs) has potential to broaden perspectives on the microbial and biogeochemical dynamics in these environments. Here, we present a metatranscriptomic survey of microbial community m... | 10.1038/nrmicro2778 | This article provides the first gene expression profiles for sulphide oxidation, denitrification, anammox and nitrification in the ETSP OMZ. |
10.1101/gr.104521.109 | 17,564,543 | Microbes are the most abundant and diverse organisms on Earth. In contrast to macroscopic organisms, their environmental preferences and ecological interdependencies remain difficult to assess, requiring laborious molecular surveys at diverse sampling sites. Here, we present a global meta-analysis of previously sampled... | 10.1038/nrmicro2778 | This paper describes a useful method for detecting co-occurrence patterns within and between microbial communities using geo-referenced taxonomic and functional-gene information. |
10.1126/science.1060161 | 86,443,661 | An afterimage induced by prior adaptation to a visual stimulus is believed to be due to bleaching of photochemical pigments or neural adaptation in the retina. We report a type of afterimage that appears to require cortical adaptation. Fixating a neon-color spreading configuration led not only to negative afterimages c... | 10.1038/nrn1869 | A clear demonstration that filling-in generates afterimage, which indicates that filling-in is accompanied by some active neural processes. |
10.1068/p190497 | 122,359,969 | The perception of transparency is highly dependent on luminance and perceived depth. An image region is seen as transparent if it is of intermediate luminance relative to adjacent image regions, and if it is perceived in front of another region and has a boundary which provides information that an object is visible thr... | 10.1038/nrn1869 | Shows that filling-in is dramatically affected by the three-dimensional interpretation of the scene. |
10.1128/aem.54.6.1472-1480.1988 | 40,690,332 | A dissimilatory Fe(III)- and Mn(IV)-reducing microorganism was isolated from freshwater sediments of the Potomac River, Maryland. The isolate, designated GS-15, grew in defined anaerobic medium with acetate as the sole electron donor and Fe(III), Mn(IV), or nitrate as the sole electron acceptor. GS-15 oxidized acetate ... | 10.1038/nrmicro3347 | This landmark paper provides the first evidence of organic C oxidation coupled to metal respiration (that is, to the transfer of electrons to Fe( III |
10.1128/aem.62.4.1458-1460.1996 | 104,088,623 | Enrichment and pure cultures of nitrate-reducing bacteria were shown to grow anaerobically with ferrous iron as the only electron donor or as the additional electron donor in the presence of acetate. The newly observed bacterial process may significantly contribute to ferric iron formation in the suboxic zone of aquati... | 10.1038/nrmicro3347 | This work is the first demonstration of microbial Fe( II ) oxidation coupled to nitrate reduction. |
10.1111/gbi.12019 | 62,383,002 | Abstract Nitrate‐reducing, Fe(II)‐oxidizing bacteria were suggested to couple with enzymatic Fe(II) oxidation to nitrate reduction. Denitrification proceeds via intermediates ( , NO) that can oxidize Fe(II) abiotically at neutral and particularly at acidic pH . Here, we present a revised Fe(II) quantification protocol ... | 10.1038/nrmicro3347 | This paper is an excellent example of coupled biotic–abiotic reactions in biogeochemical processes and describes how microbially driven denitrification leads to the formation of a reactive chemical species (that is, NO 2 − ) that prevents the unambiguous identification of enzymatic Fe( II ) oxidation. |
10.1038/ismej.2010.173 | 19,511,123 | Abstract Neutrophilic Fe-oxidizing bacteria (FeOB) are often identified by their distinctive morphologies, such as the extracellular twisted ribbon-like stalks formed by Gallionella ferruginea or Mariprofundus ferrooxydans. Similar filaments preserved in silica are often identified as FeOB fossils in rocks. Although it... | 10.1038/nrmicro3347 | This work tracks the formation of organic stalks by Fe( II )-oxidizing bacteria and suggests why this localization of Fe mineral formation away from the cell occurs and how it could be used as a biosignature. |
10.1126/science.1237331 | 80,282,588 | Superoxide and other reactive oxygen species (ROS) originate from several natural sources and profoundly influence numerous elemental cycles, including carbon and trace metals. In the deep ocean, the permanent absence of light precludes currently known ROS sources, yet ROS production mysteriously occurs. Here, we show ... | 10.1038/nrmicro3347 | This paper shows that superoxide is produced by diverse heterotrophic organisms, which expands superoxide production from sunlit environments into darker waters. |
10.1111/j.1365-2958.2007.05783.x | 107,164,439 | Summary Dissimilatory reduction of metal (e.g. Fe, Mn) (hydr)oxides represents a challenge for microorganisms, as their cell envelopes are impermeable to metal (hydr)oxides that are poorly soluble in water. To overcome this physical barrier, the Gram‐negative bacteria Shewanella oneidensis MR‐1 and Geobacter sulfurredu... | 10.1038/nrmicro3347 | This work highlights the role of multihaem c -type cytochromes in bacterial electron transfer to solid metal oxides and hydroxides. |
10.1073/pnas.0710525105 | 104,382,687 | Bacteria able to transfer electrons to metals are key agents in biogeochemical metal cycling, subsurface bioremediation, and corrosion processes. More recently, these bacteria have gained attention as the transfer of electrons from the cell surface to conductive materials can be used in multiple applications. In this w... | 10.1038/nrmicro3347 | References 123 and 124 demonstrate that the Fe( III )-reducing bacteria S. oneidensis MR-1 produces and secretes flavins that mediate extracellular electron transfer and therefore potentially facilitate the interaction between bacteria and their solid ferric substrate. |
10.1126/science.1089134 | 20,869,312 | A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain. Participants were scanned while playing a virtual ball-tossing game in which they were ultimately excluded. Paralleling results from physical pain ... | 10.1038/nrn3231 | This was the first study to examine the neural correlates of social pain in humans and the first to show activation of affective pain-related neural regions in response to social exclusion. |
10.1126/science.277.5328.968 | 60,159,362 | Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious s... | 10.1038/nrn3231 | This study creatively highlights the role of the dACC in the affective component of pain. |
10.1177/0956797610374741 | 39,363,728 | Pain, whether caused by physical injury or social rejection, is an inevitable part of life. These two types of pain—physical and social—may rely on some of the same behavioral and neural mechanisms that register pain-related affect. To the extent that these pain processes overlap, acetaminophen, a physical pain suppres... | 10.1038/nrn3231 | This study demonstrated that Tylenol, a physical pain reliever, could reduce social pain as well. |
10.1073/pnas.1102693108 | 83,329,012 | How similar are the experiences of social rejection and physical pain? Extant research suggests that a network of brain regions that support the affective but not the sensory components of physical pain underlie both experiences. Here we demonstrate that when rejection is powerfully elicited—by having people who recent... | 10.1038/nrn3231 | This study included both a physical and social pain task, and highlighted overlapping neural activity in response to both tasks. |
10.1073/pnas.0812612106 | 19,378,994 | Scientific understanding of social pain—the hurt feelings resulting from social rejection, separation, or loss—has been facilitated by the hypothesis that such feelings arise, in part, from some of the same neural and neurochemical systems that generate the unpleasant feelings resulting from physical pain. Accordingly,... | 10.1038/nrn3231 | This study demonstrated that a gene linked with physical pain sensitivity ( OPRM1 ) is also associated with rejection sensitivity. |
10.1002/hipo.20520 | 20,389,267 | Abstract Individual medial entorhinal cortex (mEC) ‘grid’ cells provide a representation of space that appears to be essentially invariant across environments, modulo simple transformations, in contrast to multiple, rapidly acquired hippocampal maps; it may therefore be established gradually during rodent development. ... | 10.1038/nrn3766 | This paper proposes the only model for grid cells that is not primarily based on path integration. Grids are formed through a self-organizing mechanism that combines Hebbian plasticity, feedforward spatially selective input and neuronal adaptation. |

Although the identity of the ubiquitinated protein specific to either disorder was unknown, we showed that TDP-43 is the major disease pro... | 10.1038/nrn2420 | This study shows that the tau-negative, ubiquitin-positive lesions in some forms of frontotemporal dementia and amyotrophic lateral sclerosis contain the protein TDP-43. |
10.1126/science.1113694 | 103,827,988 | Neurofibrillary tangles (NFTs) are the most common intraneuronal inclusion in the brains of patients with neurodegenerative diseases and have been implicated in mediating neuronal death and cognitive deficits. Here, we found that mice expressing a repressible human tau variant developed progressive age-related NFTs, ne... | 10.1038/nrn2420 | This study shows that NFT formation is not related to functional impairment in mice. |
10.1126/science.1141736 | 100,515,169 | Many potential treatments for Alzheimer's disease target amyloid-β peptides (Aβ), which are widely presumed to cause the disease. The microtubule-associated protein tau is also involved in the disease, but it is unclear whether treatments aimed at tau could block Aβ-induced cognitive impairments. Here, we found that re... | 10.1038/nrn2420 | This study shows that tau reduction protects from Aβ-mediated toxicity and excitotoxicity. |
10.1126/science.1105681 | 103,817,875 | We identified axonal defects in mouse models of Alzheimer's disease that preceded known disease-related pathology by more than a year; we observed similar axonal defects in the early stages of Alzheimer's disease in humans. Axonal defects consisted of swellings that accumulated abnormal amounts of microtubule-associate... | 10.1038/nrn2420 | This study identifies correlates of impaired axonal transport in APP transgenic mice and AD brains. Formation of spheroids increases with reduced kinesin function. |
10.1126/science.1062382 | 83,188,826 | The microtubule-binding protein tau has been implicated in the pathogenesis of Alzheimer's disease and related disorders. However, the mechanisms underlying tau-mediated neurotoxicity remain unclear. We created a genetic model of tau-related neurodegenerative disease by expressing wild-type and mutant forms of human ta... | 10.1038/nrn2420 | This study shows in D. melanogaster that tau-mediated neurodegeneration can occur in the absence of NFT formation. |
10.1073/pnas.97.20.11038 | 45,559,644 | To determine the genetic causes and molecular mechanisms responsible for neurobehavioral differences in mice, we used highly parallel gene expression profiling to detect genes that are differentially expressed between the 129SvEv and C57BL/6 mouse strains at baseline and in response to seizure. In addition, we identifi... | 10.1038/nrn2420 | This study shows differentially regulated genes in subregions of the hippocampus. |
10.1002/ana.20009 | 41,758,566 | Abstract This report describes the first human study of a novel amyloid‐imaging positron emission tomography (PET) tracer, termed Pittsburgh Compound‐B (PIB), in 16 patients with diagnosed mild AD and 9 controls. Compared with controls, AD patients typically showed marked retention of PIB in areas of association cortex... | 10.1038/nrn2420 | This study shows that the Pittsburgh Compound-B (PIB) is a suitable PET tracer in vivo |
10.1073/pnas.2034101100 | 79,386,785 | The lack of a specific biomarker makes preclinical diagnosis of Alzheimer's disease (AD) impossible, and it precludes assessment of therapies aimed at preventing or reversing the course of the disease. The development of a tool that enables direct, quantitative detection of the amyloid-β deposits found in the disease w... | 10.1038/nrn2420 | This study introduces the Pittsburgh Compound-B (PIB) that binds to Aβ plaques in vivo |
10.1073/pnas.092136199 | 83,183,079 | Senile plaques and neurofibrillary tangles, the two hallmark lesions of Alzheimer's disease, are the results of the pathological deposition of proteins normally present throughout the brain. Senile plaques are extracellular deposits of fibrillar β-amyloid peptide (Aβ); neurofibrillary tangles represent intracellular bu... | 10.1038/nrn2420 | This study shows in primary neuronal cultures of Tau −/− mice that tau is needed for Aβ-mediated toxicity. |
10.1126/science.1131864 | 62,551,961 | Protein aggregation is an established pathogenic mechanism in Alzheimer's disease, but little is known about the initiation of this process in vivo. Intracerebral injection of dilute, amyloid-β (Aβ)–containing brain extracts from humans with Alzheimer's disease or β-amyloid precursor protein (APP) transgenic mice induc... | 10.1038/nrn2420 | This study shows shared properties between prions and Aβ with regards to host and agent dictating pathology. |
10.1126/science.1132341 | 62,565,445 | Although BACE1 (beta-site amyloid precursor protein–cleaving enzyme 1) is essential for the generation of amyloid-b peptide in Alzheimer's disease, its physiological function is unclear. We found that very high levels of BACE1 were expressed at time points when peripheral nerves become myelinated. Deficiency of BACE1 r... | 10.1038/nrn2420 | This study identifies a role for the β-secretase BACE in processing neuregulin. |
10.1073/pnas.98.4.2017 | 60,814,142 | Choline acetyltransferase (ChAT; EC 2.3.1.6 ) catalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses. Mutations in genes encoding ChAT affecting motility exist in Caenorhabditis elegans and Drosophila , but no CHAT mutations have been observed in humans to date. He... | 10.1038/nrn1101 | This is the first description of mutations in CHAT in humans.
