Evolution of Nova-dependent splicing regulation in the brain. (1/71)

A large number of alternative exons are spliced with tissue-specific patterns, but little is known about how such patterns have evolved. Here, we study the conservation of the neuron-specific splicing factors Nova1 and Nova2 and of the alternatively spliced exons they regulate in mouse brain. Whereas Nova RNA binding domains are 94% identical across vertebrate species, Nova-dependent splicing silencer and enhancer elements (YCAY clusters) show much greater divergence, as less than 50% of mouse YCAY clusters are conserved at orthologous positions in the zebrafish genome. To study the relation between the evolution of tissue-specific splicing and YCAY clusters, we compared the brain-specific splicing of Nova-regulated exons in zebrafish, chicken, and mouse. The presence of YCAY clusters in lower vertebrates invariably predicted conservation of brain-specific splicing across species, whereas their absence in lower vertebrates correlated with a loss of alternative splicing. We hypothesize that evolution of Nova-regulated splicing in higher vertebrates proceeds mainly through changes in cis-acting elements, that tissue-specific splicing might in some cases evolve in a single step corresponding to evolution of a YCAY cluster, and that the conservation level of YCAY clusters relates to the functions encoded by the regulated RNAs.  (+info)

Currently, the physiological roles of amyloidogenic proteins (APs) in human brain, such as amyloid-β and α-synuclein, are elusive. Given that many APs arose by gene duplication and have been resistant against the pressures of natural selection, APs may be associated with some functions that are advantageous for survival of offspring. Nonetheless, evolvability is the sole physiological quality of APs that has been characterized in microorganisms such as yeast. Since yeast and human brain may share similar strategies in coping with diverse range of critical environmental stresses, the objective of this paper was to discuss the potential role of evolvability of APs in aging-associated neurodegenerative disorders, including Alzheimers disease and Parkinsons disease ...

The immune system long ago evolved ways to recognize pathogenic invaders through their antigens. For instance, these antigens, or fragments of the pathogens, may come from pathogenic proteins that have been taken up and processed into small peptides a few amino acids long, which are then taken up by specialized antigen-presenting cells (APC). The APCs "present" the antigens on their surfaces by displaying them in molecular complexes with the so-called major histocompatibility complex (MHC) proteins. When a pathogen invades the immune system, APCs alert T cells by displaying the pathogenic antigens. When specific T cells see the antigen in the MHC, they generate a systemic immune response designed to lead to the destruction of the pathogen, starting with a cascade of internal activation events.

Although the putative biological consequences of cross-seeding have not been investigated in detail, there are several studies suggesting a molecular cross-talk between misfolded proteins in vivo. Perhaps the most emblematic study of cross-seeding in animal models is the one involving Aβ and tau proteins. The simultaneous brain accumulation of these proteins is the main hallmark of AD. Studies in animal models using various transgenic mice revealed that Aβ is able to accelerate the aggregation of tau; however, it seems that tau aggregates do not have the same effect over Aβ [19], [20]. These findings suggest a possibly unidirectional cross-seeding. However, it is also possible that this outcome may be mediated by indirect processes, for example, Aβ aggregates may activate certain kinases responsible for tau phosphorylation, leading to higher misfolding and aggregation of this protein [21].. Another interaction that has been studied in some detail is between α-synuclein and the misfolded ...
en] Amyloidogenic model peptides are invaluable for investigating assembly mechanisms in disease related amyloids and in protein folding. During aggregation, such peptides can undergo bifurcation leading to fibrils or crystals, however the mechanisms of fibril-to-crystal conversion are unclear. We navigate herein the energy landscape of amyloidogenic peptides by studying a homologous series of hexapeptides found in animal, human and disease related proteins. We observe fibril-to-crystal conversion occurring within single aggregates via untwisting of twisted ribbon fibrils possessing saddle-like curvature and cross-sectional aspect ratios approaching unity. Changing sequence, pH or concentration shifts the growth towards larger aspect ratio species assembling into stable helical ribbons possessing mean-curvature. By comparing atomistic calculations of desolvation energies for association of peptides we parameterise a kinetic model, providing a physical explanation of fibril-to-crystal ...
Each chameleon species has its own color range. In general calm chameleons show green color. They exhibit darker colors like bright yellow to show their anger. It also serves the purpose of threatening others. Male chameleons when want to mate, show lighter, multicolored patterns. Female chameleons show black with orange strips or dark brown color when they are carrying eggs. Chameleons become darker to absorb the heat effectively and show lighter grey color to reflect the light. A sick chameleon appears pale due to lack of sufficient energy to change color. ...

A wide range of materials may be encapsulated in a starch matrix by combining the material with a high temperature-stabilized pressurized dispersion of starch in the presence of salt. The temperature-stabilized starch dispersion acts as a protective colloid; upon subsequent rapid reduction of the pressure, the mixture cools and the starch polymer chains collapse upon themselves, encapsulating the core material in particulate form.
Lincontro col cinema nel 1913, chiamato dal boss Mack Sennett per la sua neonata casa di produzione cinematografica Keystone per recitare al fianco di Mabel Normand, Roscoe Arbuckle, Chester Conklin. Diede vita al personaggio di Ambrose, galante, erculeo dongiovanni, dagli occhi infossati in orbite scure, un paio di maestosi baffoni e un ciuffo a dividere la fronte spaziosa. Nel 1914 sarà partner di Charlie Chaplin nei suoi primi cortometraggi Keystone. Con Syd Chaplin e Gloria Swanson alcune apparizioni tra il 1915 e il 1916. Ambrose lascerà la Keystone nel 1917 per seguire Ford Sterling e Pathé Lehrman alla L-KO. La prematura scomparsa di Eric Campbell, magnifica spalla nel ruolo del cattivo, gli varrà la chiamata di Chaplin per sostituirlo in alcuni film seguenti il 1917 e fino alla memorabile interpretazione di Giacomone (Big Jim) nel capolavoro La febbre delloro del (1925)..

[more ▼]. Depositions of proteins in form of amyloid and non-amyloid plaques are common pathogenic signs of more than 20 degenerative diseases affecting the central nervous system or a variety of peripheral tissues. Among the neuropathological conditions, Alzheimers, Parkinsons and the prion diseases, such as Creutzfeldt-Jakob disease (CJD), present ambiguities as regarding their differential diagnosis. At present, their diagnosis must be confirmed by post-mortem examination of the brain. Currently the ante-mortem diagnosis is still based on the integration of multiple data (clinical, paraclinical and biological analyses) because no unique marker exists for such diseases. The detection of specific biomarkers ...
Cryoglobulinemic vasculitis (CV) is an immune-complex-mediated systemic vasculitis involving small-medium sized vessels. A causative role of hepatitis C virus (HCV) in over 4/5 patients has been definitely established on the basis of epidemiological, pathological, and laboratory studies. There is great geographical heterogeneity in the prevalence of CV as well as other HCV-related immuno-lymphoproliferative disorders. Thus, unknown environmental and/or genetic co-factors should contribute to the pathogenesis of these conditions. Due to the biological properties, HCV genomic sequences cannot be integrated into the host genome; the virus could trigger the immunological alterations only indirectly by exerting a chronic stimulus to the immune system. Recent laboratory observations gave us new important insights on the complex pathogenetic mechanism(s) of HCV-related CV. Firstly, the HCV envelop protein E2, able to bind CD81 molecule expressed on B-lymphocytes, might be involved in the first steps of ...

Author Summary The aggregation of proteins in tissues is associated with the pathogenesis of more than 40 human diseases. The polypeptides underlying disorders such as Alzheimers and Parkinsons are devoid of any regular structure, whereas the polypeptides causing familial amyotrophic lateral sclerosis or nonneuropathic systemic amyloidosis correspond to globular proteins. Little is known about the mechanism by which globular proteins under physiological conditions aggregate from their initially folded and soluble conformations. Interestingly, several of these pathogenic proteins display quaternary structure or are bound to other proteins in their physiological context. In the present work, we show that protein-protein interaction surfaces and regions with high aggregation propensity significantly overlap in these polypeptides. This suggests that the formation of native complexes and self-aggregation reactions probably compete in the cell, explaining why point mutations affecting the interface or the
Autophagy (from the Greek auto - self, phagein - to eat), is the basic cellular catabolic mechanism that involves cell degradation of unnecessary or dysfunctional cellular components through the actions of lysosomes. During this process, targeted cytoplasmic constituents are isolated from the rest of the cell within a double-layered membrane vesicle known as an autophagosome. The autophagosome then fuses with a lysosome and its cargo is degraded and recycled. Autophagy has been implicated in a number of fundamental biological processes including cellular homeostasis, aging, immunity, protein quality control, as well as in many different diseases like cancer, cardiomyopathy, neurodegeneration, infectious diseases and hepatic encephalopathy. While a decreased autophagic activity may intervene with protein degradation, its increased activity appears to facilitate the clearance of aggregation-prone intracytoplasmic pathogenic proteins like mutant huntingtin or α-synuclein, and pathogens, as well as ...
Deleted Sequence (10 minutes) - Heres a treat for Chaplinologists. While production on the main stage was suspended because of fire-and-water damage and reconstruction, Chaplin devised a restaurant scene with himself, Merna Kennedy, Harry Crocker, and Doc Stone, who played twin prize fighters (thanks to double-exposure). Chaplin shot the sequence with the intention of inserting it into the final cut. The rest of The Circus was strong enough to work without it, so the restaurant scene never made the edit. Here it is, a self-contained one-reel short all by itself. The scene opens with a clever bit as the Tramp practices his tightrope routine on an upturned rake before escorting Merna along a still rural-looking Sunset Blvd., where they meet Rex. When the Tramp tries to upstage Rexs gallantry, he instead turns a matrons arm-load of wrapped fish into a sidewalk calamity. After they arrive at the restaurant, the Tramp connives with a bullying fighter to impress Merna, with similar results. The ...

Hidden Markov Models power many state-of-the-art tools in the field of protein bioinformatics. While excelling in their tasks, these methods of protein analysis do not convey directly information on medium and long-range residue-residue interactions. This requires an expressive power of at least context-free grammars. However, application of more powerful grammar formalisms to protein analysis has been surprisingly limited. We have developed a probabilistic grammatical framework for problem-specific protein languages, which has been already successfully applied to recognition of ligand binding sites. The core of the model consists of a probabilistic context-free grammar (PCFG), automatically inferred by a genetic algorithm from only a generic set of expert-based rules and positive training sequences. Here, we show that the PCFG approach matches state-of-the-art performance in two other tasks: classification of transmembrane helix-helix pairs and recognition of amyloidogenic peptides. First, the
Researchers studying the natural history of Alzheimers disease are grappling with a puzzling group of volunteers-amyloid-free and cognitively normal older adults who show other biomarker evidence of neurodegeneration. Initially reported in 2011, sizable numbers of what were, perhaps wrongly, thought to be preclinical AD patients now turn up as having this suspected non-amyloid pathology (SNAP) in two new studies. In a longitudinal analysis of Minnesota seniors, 42 percent of those who eventually racked up high brain amyloid at baseline already had biomarkers suggestive of neurodegeneration even though their brain-amyloid scan was still negative. And a cross-sectional study by researchers in California found that many cognitively normal elderly had neurodegeneration biomarkers in brain regions typically affected by AD, yet lacked Aβ deposition. These California seniors were more likely than those with high brain Aβ to have cerebrovascular disease and perform poorly on cognitive tests. Reported ...
When feeding a veiled chameleon, a combination of at least five different insect sources should be provided. Insects and fruits and vegetables can be combined into a tipped container with a branch inserted inside to allow the animal to exit and enter its food dish and to prevent any insects from escaping. Silkworms, which are soft-bodied caterpillars, can be obtained by mail order from a variety of places and are relatively easy to keep on hand. Fruit flies are ideal for neonate chameleons or smaller species of chameleons. Crickets typically comprise a significant part of a chameleons diet, however, these insects have a poor calcium to phosphorous ratio, and a calcium supplement should be included. Mealworms are great to use in that they can be loaded with nutrients by feeding them fruits and vegetables and then fed to the animal. Zoophobus, which look like larger versions of mealworms, can also be used as food. However, king worms or giant mealworms should be avoided in that these insects ...

Evidence shows that diabetes increases the risk of developing Alzheimers disease (AD). Many efforts have been done to elucidate the mechanisms linking diabetes and AD. To demonstrate that mitochondria may represent a functional link between both pathologies, we compared the effects of AD and sucrose-induced metabolic alterations on mouse brain mitochondrial bioenergetics and oxidative status. For this purpose, brain mitochondria were isolated from wild-type (WT), triple transgenic AD (3xTg-AD), and WT mice fed 20% sucrose-sweetened water for 7 months. Polarography, spectrophotometry, fluorimetry, high-performance liquid chromatography, and electron microscopy were used to evaluate mitochondrial function, oxidative status, and ultrastructure. Western blotting was performed to determine the AD pathogenic protein levels. Sucrose intake caused metabolic alterations like those found in type 2 diabetes. Mitochondria from 3xTg-AD and sucrose-treated WT mice presented a similar impairment of the ...
Gelatin is made out of animal proteins. When you add water to the gelatin, long chains of protein form. Water gets trapped in the middle of these long chains, and turns the liquid into a semi-solid. Since the enzyme bromelain digests proteins, it eats away at the gelatin. The protein chains collapse, making everything watery again.. In the process of this experiment I did some studying and also learned that papaya, mango, guava, ginger, kiwi and figs also contain protein-digesting enzymes. Isnt that interesting? They will also prevent gelatin from setting up. Our kiwi gelatin followed the same pattern as the pineapple and did not set up!. ...
Chameleons* are among the most distinctive and charismatic of lizards, and a long list of anatomical features makes them unusual relative to other members of the group. Most of the sorts of things I have in mind (those grasping hands and feet, the protrusible tongue and so on) are well known. Less familiar is that chameleons are not all branch-climbing specialists with prehensile tails: the group also includes a substantial number of terrestrial, leaf- and twig-mimicking taxa, many of which are tiny

The review summarizes research into the highly relevant topics of cholinesterase and amyloid aggregation inhibitors connected to tacrine congeners, both of which are associated with neurogenerative diseases. Various opinions will be discussed regarding the dual binding site inhibitors which are characterized by increased inhibitor potency against acetylcholin/butyrylcholine esterase and amyloid formation. It is suggested that these compounds can both raise levels of acetylcholine by binding to the active site, and also prevent amyloid aggregation. In connection with this problem, the mono/dual binding of the multifunctional derivatives of tacrine, their mode of action and their neuroprotective activities are reported. The influence of low molecular compounds on protein amyloid aggregation, which might be considered as a potential therapeutic strategy in the treatment of Alzheimers disease is also reported. Finally, attention is paid to some physico-chemical factors, such as desolvation energies
The IDEAS Study is an observational, open-label, longitudinal cohort study designed to assess the impact of amyloid PET on patient-oriented outcomes in Medicare beneficiaries with mild cognitive impairment (MCI) or dementia of uncertain etiology. The study falls under the Centers for Medicare & Medicaid Services (CMS) Coverage with Evidence Development (CED) policy. A total of 18,488 Medicare beneficiaries meeting Appropriate Use Criteria (AUC) for amyloid PET will be enrolled over 24 months at sites throughout the United States.

Being one of the hallmarks of Alzheimers disease, β-amyloid (Aβ) aggregates induce complicated neurotoxicity. Evidences show that the underlying mechanism of neurotoxicity involves a glutamate receptor subtype, N-methyl-D-aspartate (NMDA) receptor, an increase in intracellular calcium(II) ion loading as well as an elevation in oxidation stress. In this work, among the 35 chemical components of Chinese herbal medicines (CHMs) being screened for inhibitors of Aβ aggregation, four of them, namely albiflorin, aloeemodin, neohesperidin and physcion, were found for the first time to exhibit a potent inhibitory effect on Aβ(1-40) and Aβ(1-42) aggregation. Their neuroprotective capability on primary hippocampal neuronal cells was also investigated by MTT assay, ROS assay and intracellular calcium(II) ion concentration measurement. It was interesting to find that physcion was rather toxic to neuronal cells while albiflorin, aloeemodin and neohesperidin reduced the toxicity and ROS induced by both monomeric
Transthyretin (TTR) is a homotetrameric plasma protein that, as a result of a set of not yet fully characterized conformational changes, forms fibrillar aggregates that are the major protein component of amyloid deposits. More than 80 mutations associated with TTR amyloid deposition have been described in the literature. X-ray crystallography was used to elucidate the three-dimensional structure of two important TTR variants: TTR Y78F, an amyloidogenic protein, and TTR R104H, which is associated with a protective effect over the amyloidogenic V30M mutation. The structures of those two TTR variants have been determined in space group P2(1)2(1)2 to 1.55 and 1.60 angstroms resolution, respectively, using molecular-replacement techniques. Detailed analysis of the protein model for TTR Y78F indicates a destabilization of the contacts between the alpha-helix and AB loop and the body of the molecule, intimately related to the amyloidogenic nature; contrastingly, in the TTR R104H variant new contacts ...
If exosomes offer cells a way to get rid of Aβ, then they could spread the peptide throughout the brain. For now, there is no evidence that neurons take up vesicles with pathogenic proteins in them, said Rajendran. Martin Hallbeck, Linköping University, Sweden, is studying this question in neurons derived from induced pluripotent stem cells made from healthy human fibroblasts. He incubated these neuron cultures with exosomes from neuroblastoma cells laden with fluorescently labeled α-synuclein or Aβ oligomers. Using confocal microscopy, he saw neurons ingest the exosomes and their proteins. When he then co-cultured these cells with fresh neurons that had not been incubated with exosomes, he saw that labeled oligomers of both α-synuclein and Aβ passed between them via exosomes. However, if he blocked endocytosis, the cells took up almost none. "These results suggest that exosomes provide at least one way for toxic aggregates to spread from neuron to neuron," Hallbeck told Alzforum. While he ...
While the film itself isnt much to write home about, Jackie delivers several creative fight sequences in Around the World in 80 Days two which have already made the list. This is the best fight from the film and is one of the best examples of the typical type of fight he would put together for his Hollywood films. While the true fight fan would be disappointed, Chan does little more than simple kicks and punches, but for one looking for more creativity, this sequence is genius. I love the methodical way in which Chan paints a landscape on a canvas during the fight, accidentally punches himself in the mirror and in true Chaplin fashion creates a couple hilarious visual gags going up the side of a building on a rope. In fact, Chan later loses his pants on a statue (with a Chaplin mustache from the art fight earlier) in a reference to Chaplin in the opening scenes of City Lights ...
The "Special Course" which typically launches the annual AANP meeting was anything but typical this year. Rather than the usual series of research presentations which has characterized the first day of the meeting, the 2015 edition of the "Special Course" focused on need-to-know practical topics. Dr. Beatriz Lopes put together a program that offered something for everyone -- from trainee to seasoned practitioner. The morning started with a presentation by Dr. Caterina Giannini on primary CNS lymphoma, as well as its mimickers and precursors. Far from being a straightforward diagnosis, lymphoma -- particularly in the setting of corticosteroid therapy -- can be mistaken for anything from multiple sclerosis to infarct. Next, two eminent scholars from Paris, Drs. Francoise Gray and Elisabeth Tournier-Lasserve, presented a three-part lecture on the hereditary non-amyloid small vessel diseases of the brain. Then Charles Eberhart showed up from Johns Hopkins to provide a primer on ophthalmic pathology, ...
Amanita ceciliae is characterized by bearing a large fruit body with a brown cap 5-12 cm (2.0-4.7 in) across. The cap has charcoal-grey patches, which are easily removable. The stipe is 7-18 cm (2.8-7.1 in) long, white in colour, and there is no ring on it. It is slightly tapered to the top, and has irregular cottony bands girdling the base.. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2-11.7 micrometres.. The cap is 5-12 cm (2.0-4.7 in) across, shape ranging from convex to flat. It is upturned, and has a deep-coloured margin. There is a low umbo. It is grey to a brownish black in colour, darkest in the center and paler towards the margin. Generally smooth, the cap surface is slightly sticky when moist. The cap surface is characterized by having loose, fleecy, charcoal-grey patches of volval remnants scattered across it. The patches are easily removed. The margin is strongly striated. The cap colour may vary, and pale forms are known to exist, ...

Ver más] α-Synuclein (αSyn) is a 140-residue amyloid-forming protein whose aggregation is linked to Parkinsons disease (PD). It has also been found to play a critical role in the immune imbalance that accompanies disease progression, a characteristic that has prompted the search for an effective αSyn-based immunotherapy. In this study, we have simultaneously exploited two important features of certain heat-shock proteins (HSPs): their classical "chaperone" activities and their recently discovered and diverse "immunoactive" properties. In particular, we have explored the immune response elicited by immunization of C57BL/6 mice with an αSyn/Hsp70 protein combination in the absence of added adjuvant. Our results show differential effects for mice immunized with the αSyn/Hsp70 complex, including a restrained αSyn-specific (IgM and IgG) humoral response as well as minimized alterations in the Treg (CD4+CD25+Foxp3+) and Teff (CD4+Foxp3−) cell populations, as opposed to significant changes in ...

This course concentrates on close analysis and criticism of a wide range of films, from the early silent period, classic Hollywood genres including musicals, thrillers and westerns, and European and Japanese art cinema. It explores the work of Griffith, Chaplin, Keaton, Capra, Hawks, Hitchcock, Altman, Renoir, DeSica, and Kurosawa. Through comparative reading of films from different eras and countries, students develop the skills to turn their in-depth analyses into interpretations and explore theoretical issues related to spectatorship.

Localized cutaneous amyloidosis (LCA) refers to a condition characterized by the deposition of amyloid or amyloid-like proteins in the dermis. Localized cutaneous amyloidosis encompasses several conditions characterized by amyloid deposition, including macular amyloidosis and lichen amyloidosis.
Cold is normally avoided by ectothermic animals, which rely on environmental temperature to keep their body temperature high. When exposed to cold, metabolic rate slows down, muscles stiffen, and escaping from predators or catching a meal becomes increasingly difficult. This is why the distribution of chameleon species across a wide range of thermal habitats, from deserts to alpine zones, is so intriguing. In 1982, Stephen Reilly reported that some species of chameleons can even feed at body temperatures as low as 3.5°C, allowing them to take advantage of thermal niches other lizards cant exploit. Although these observations were made almost 30 years ago, the answer to how chameleons are able to catch prey at very low temperatures had remained elusive until now.. Christopher Anderson and Stephen Deban, from the University of South Florida, USA, believe the secret is in their tongues. Chameleons are sit-and-wait predators; they ambush their prey by rapidly projecting their sticky tongue once ...
We have produced a panel of 32 unique monoclonal antibodies that recognize common structural elements in amyloid aggregates, like the alpha-synuclein aggregates that are believed to play an important role in PD pathogenesis. Although these antibodies were originally produced against Abeta amyloid from Alzheimer s disease, we found that many of them recognize common or generic epitopes (or antibody binding sites) that occur on amyloid aggregates from a number of different amyloids made from different protein sequences. For some of these antibodies, we have already shown that interact with alpha-synuclein aggregates in vitro. In this project, we will test the immunoreactivity of all of the antibodies against alpha-synuclein oligomers and fibrils. We will also test whether any of the antibodies can detect pathological oligomers in human PD brain. Antibodies that react with pathological amyloid aggregates in brain would represent candidates for therapeutic development.. Relevance to ...
Chaplin F (Chp F) is a secreted surface-active peptide involved in the aerial growth of Streptomyces. While Chp E demonstrates a pH-responsive surface activity, the relationship between Chp F structure, function and the effect of solution pH is unknown. Chp F peptides were found to self-assemble into amyloid fibrils at acidic pH (3.0 or the isoelectric point (pI) of 4.2), with ~99% of peptides converted into insoluble fibrils. In contrast, Chp F formed short assemblies containing a mixture of random coil and β-sheet structure at a basic pH of 10.0, where only 40% of the peptides converted to fibrils. The cysteine residues in Chp F did not appear to play a role in fibril assembly. The interfacial properties of Chp F at the air/water interface were altered by the structures adopted at different pH, with Chp F molecules forming a higher surface-active film at pH 10.0 with a lower area per molecule compared to Chp F fibrils at pH 3.0. These data show that the pH responsiveness of Chp F surface activity is

  • A protein secreted with insulin travels through the bloodstream and accumulates in the brains of individuals with type 2 diabetes and dementia, in the same manner as the amyloid beta (Αβ) plaques that are associated with Alzheimer's disease, a study by researchers with the UC Davis Alzheimer's Disease Center has found. (ucdavis.edu)
  • The study is the first to identify deposits of the protein, called amylin, in the brains of people with Alzheimer's disease, as well as combined deposits of amylin and Aβ plaques, suggesting that amylin is a second amyloid as well as a new biomarker for age-related dementia and Alzheimer's.

  • Pathologies and dementias of the nervous system such as Alzheimer's disease and Parkinson's disease are associated with tau proteins that have become defective and no longer stabilize microtubules properly. (wikipedia.org)
  • Hyperphosphorylation of the tau protein (tau inclusions, pTau) can result in the self-assembly of tangles of paired helical filaments and straight filaments, which are involved in the pathogenesis of Alzheimer's disease, frontotemporal dementia, and other tauopathies. (wikipedia.org)
  • An alpha-synuclein fragment, known as the non-Abeta component (NAC) of Alzheimer's disease amyloid, originally found in an amyloid-enriched fraction, was shown to be a fragment of its precursor protein, NACP. (wikipedia.org)
  • The number of papers published on simulations of amyloidogenic proteins has increased rapidly during the last decade. (edu.pl)
  • FoldRx's portfolio includes clinical and pre-clinical programs for investigational compounds to treat diseases caused by protein misfolding, which is increasingly recognized as an underlying cause in many chronic degenerative diseases. (bio-medicine.org)
  • Its screening engine is rapid and efficient in evaluating potential treatment candidates in a wide range of diseases caused by misfolded proteins. (bio-medicine.org)
  • Fluorescent proteins (FPs) have great utility in identifying specific cell populations and in studying cellular dynamics in the mouse. (biologists.org)
  • By combining FoldRx's proprietary expertise in identifying and developing treatments for protein misfolding diseases with Pfizer's commercial, medical and regulatory expertise, and global strengths in patient services and reimbursement, we are taking a significant step toward potentially bringing, for the first time, a non-surgical treatment option for underserved patients affected by the deadly disease ATTR-PN," said Geno Germano, president and general manager, Pfizer Specialty Care Business Unit.

  • Atomic structures of low-complexity protein segments reveal kinked β sheets that assemble networks. (alzforum.org)
  • Inhibition or modulation of abnormal protein self-assembly, therefore, is an attractive strategy for prevention and treatment of amyloidoses. (nih.gov)
  • Tau proteins (or τ proteins, after the Greek letter with that name) are proteins that stabilize microtubules. (wikipedia.org)
  • This contrasts with MAP6 (STOP) proteins in the proximal portions of axons, which, in essence, lock down the microtubules and MAP2 that stabilizes microtubules in dendrites. (wikipedia.org)
  • To our knowledge, this report of amyloid-dependent biofilm inhibition by a human protein with no significant bactericidal or bacteriostatic activity is unique. (pnas.org)
  • We used amyloid β-protein (Aβ) to further explore the binding site(s) of CLR01 and the impact of its binding on the assembly process. (nih.gov)
  • Regarding knots, naturally-occurring proteins differ in at least two major aspects with respect to flexible polymers of equivalent length. (mdpi.com)
