    Abstract [en]

    Most ribbon worms (phylum: Nemertea) are found in marine environments, where they act as predators and scavengers. They are characterized by an eversible proboscis that is used to hunt for prey and thick mucus covering their skin. Both proboscis and epidermal mucus mediate toxicity to predators and preys. Research into the chemical nature of the substances that render toxicity has not been extensive, but it has nevertheless led to the identification of several compounds of potential medicinal use or for application in biotechnology. This review provides a complete account of the current status of research into nemertean toxins.

    Alpha-nemertides - a novel family of nemertean peptide neurotoxins2018Conference paper (Other academic)
    Abstract [en]

    We recently discovered a novel family of neuroactive peptides in nemerteans, which we have named alpha-nemertides (1). One of these peptides, nemertide alpha-1, has been the subject of detailed studies with regard to structure and effects. The peptide exhibits exceptional potency against a number of arthropod species. Moreover, in vitro experiments suggest that alpha-1 acts primarily on voltage-gated sodium channels, and that this action is selective for arthropods by two orders of magnitude over vertebrate species. Using transcriptomic and proteomic approaches, we have identified 10 alpha-nemertides, but this number is likely to increase. These peptides alongside with a series of mutants are currently under evaluation by our group, with the goal to improve our understanding of structure-function relationships. In addition, we are considering potential practical uses of alpha-nemertides. In this talk, I will describe the current status of this research project.

    Peptide ion channel toxins from the bootlace worm, the longest animal on Earth2018In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 8, article id 4596Article in journal (Refereed)
    Abstract [en]

    Polypeptides from animal venoms have found important uses as drugs, pharmacological tools, and within biotechnological and agricultural applications. We here report a novel family of cystine knot peptides from nemertean worms, with potent activity on voltage-gated sodium channels. These toxins, named the alpha-nemertides, were discovered in the epidermal mucus of Lineus longissimus, the 'bootlace worm' known as the longest animal on earth. The most abundant peptide, the 31-residue long alpha-1, was isolated, synthesized, and its 3D NMR structure determined. Transcriptome analysis including 17 species revealed eight alpha-nemertides, mainly distributed in the genus Lineus. alpha-1 caused paralysis and death in green crabs (Carcinus maenas) at 1 mu g/kg (similar to 300 pmol/kg). It showed profound effect on invertebrate voltage-gated sodium channels (e.g. Blattella germanica Na(v)1) at low nanomolar concentrations. Strong selectivity for insect over human sodium channels indicates that a-nemertides can be promising candidates for development of bioinsecticidal agents.

    The meal as a performance: food and meal practices beyond health and nutrition2018In: Ageing & Society, ISSN 0144-686X, E-ISSN 1469-1779, no 1, p. 83-107Article in journal (Refereed)
    Abstract [en]

    The proportion of elderly people in the population is increasing, presenting a number of new challenges in society. The purpose of this qualitative study was to in- vestigate how elderly persons with motoric eating difficulties perceive and perform their food and meal practices in everyday life. By using Goffman’s concept of performance as a theoretical framework together with Bourdieu’s thinking on habitus, a deeper understanding of food and meal practices is obtained. Semi- structured interviews were conducted with  elderly people (aged between  and  years) and meal observations were carried out with  of these people. Participants were found to manage food and meal practices by continuously adjust- ing and adapting to the new conditions arising as a result of eating difficulties. This was displayed by conscious planning of what to eat and when, avoiding certain foods and beverages, using simple eating aids, but also withdrawing socially during the meals. All these adjustments were important in order to be able to demonstrate proper food and meal behaviour, to maintain the façade and to act according to the perceived norms. As well as being a pleasurable event, food and meals were also perceived in terms of being important for maintaining health and as ‘fuel’ where the main purpose is to sustain life. This was strongly connected to the social context and the ability to enjoy food and meals with family members and friends, which appeared to be particularly crucial due to the impending risk of failing the meal performance.

    Dietary habits of Swedish university students in nutrition science between 2001 and 20162016In: Abstracts. The 11th NORDIC NUTRITION CONFERENCE NNC2016. “Bridging nutrition sciences for better health in the Nordic countries”, 2016, article id P470Conference paper (Other academic)
    Abstract [en]

    While the Swedish nutrition recommendations have been kept relatively constant in recent years, public attitudes to different diets have been swinging faster. The National food survey (Riksmaten), being performed in Sweden only once per decade, cannot identify any corresponding rapid changes in diets. Hence, our understanding of potential fluctuations is limited. During the last 15 years, nutrition students at the Linnaeus University (formerly University of Kalmar) have reported their food intake in the context of the course Diet, Nutrition and Health 7,5 hp. The result is an extensive data set comprising more than 1100 individuals and over 2500 days of food intake reports, and although not originally intended or designed as a study, it became apparent that these data could be of interest as an indicator for national dietary trends. Food intake was reported (by weighing or estimating the amounts) for two weekdays and one weekend day per student, along with age, length, sex and weight. Food intake was translated to nutrient intake using Dietist Net software (Kost & Näringsdata).  Admittedly, the data set has some validity problems: the students differ from the Riksmaten study groups in mean age and geographical distribution, and all data was collected during March-April. As students in a nutrition course, they can also be expected to be more interested and more knowledgeable in the nutrition subject than the average person. Nevertheless, the results clearly demonstrate a substantial change in nutrient intake from 2006 and onwards, where the energy from carbohydrates decreased from above 50% to below 40%, and where the energy intake from fat increased from about 25% to 36%. Further details, such as the effects on the intake of selected micronutrients, will be presented.

    Discovery of novel ion-channel active peptide toxins in a North Sea Ribbon Worm2016Conference paper (Other academic)
    Abstract [en]

    Ribbon worms (nemerteans) are marine predators, which capture their prey using a proboscis containing a mixture of toxins which brings on rapid paralysis [1]. In addition, their epidermis contains thick mucus of similar toxic constitution. One very potent toxin reported in ribbon worm mucus is tetrodotoxin (TTX). However, despite significant efforts, Strand et al. [2] were unable to detect any TTX, neither in the mucus of the ribbon worm Lineus longissimus, nor from Vibrio alginolyticus cultures isolated from and cultivated in the mucus. These observations challenged the notion of general presence of TTX in ribbon worm mucus, and prompted us to look for other toxins [3]. Using LC-MS analysis of mucus extracts, we identified three peptides present in significant amounts. The peptides were sequenced using a combination of MS/MS analysis and transcriptomics, and whereas one of them strongly resembles the only peptide toxin previously characterized from ribbon worms, Neurotoxin B-IV [4], the other two were found to represent a previously unknown class of peptide toxins. The most abundant of these was synthesized, and its 3D structure determined. Preliminary toxicity tests on shore crab (C. maenas) indicated toxicity (through paralysis) on par with that of TTX. Further analyses have indicated that its toxic effects are due to binding to voltage sensitive sodium channels.

     

    With L. longissimus as our primary target, we are now mapping the presence of peptide toxins in ribbon worms, with the objectives to establish routes for synthesis, and to characterize the biological activities and structures of these peptides. The number of peptides of this novel class is increasing, and synthesis and characterization is well underway. The striking potencies of these peptides make them potentially amenable as novel insecticidal or anthelmintic leads, pharmacological tools or in biotechnology applications.

    The Bacterial (Vibrio alginolyticus) Production of Tetrodotoxin in the Ribbon Worm Lineus longissimus: Just a False Positive?2016In: Marine Drugs, ISSN 1660-3397, E-ISSN 1660-3397, Vol. 14, no 4, article id 63Article in journal (Refereed)
    Abstract [en]

    We test previous claims that the bacteria Vibrio alginolyticus produces tetrodotoxin (TTX) when living in symbiosis with the nemertean Lineus longissimus by a setup with bacteria cultivation for TTX production. Toxicity experiments on the shore crab, Carcinus maenas, demonstrated the presence of a paralytic toxin, but evidence from LC-MS and electrophysiological measurements of voltage-gated sodium channel–dependent nerve conductance in male Wistar rat tissue showed conclusively that this effect did not originate from TTX. However, a compound of similar molecular weight was found, albeit apparently non-toxic, and with different LC retention time and MS/MS fragmentation pattern than those of TTX. We conclude that C. maenas paralysis and death likely emanate from a compound <5 kDa, and via a different mechanism of action than that of TTX. The similarity in mass between TTX and the Vibrio-produced low-molecular-weight, non-toxic compound invokes that thorough analysis is required when assessing TTX production. Based on our findings, we suggest that re-examination of some published claims of TTX production may be warranted.

    The toxicity of ribbon worms: alpha-nemertides or tetrodotoxin, or both?2016In: Planta Medica, ISSN 0032-0943, E-ISSN 1439-0221, Vol. 82, no Supplement 1, article id P549Article in journal (Other academic)
    Abstract [en]

    The marine ribbon worms (nemerteans) are predators which capture their prey by everting a proboscis carrying a mixture of toxins which brings on rapid paralysis [1]. Moreover, ribbon worms have a thick layer of epidermal mucus of similar constitution. Tetrodotoxin (TTX) has been identified as one of these toxins [2]. The extreme toxicity of TTX (lethal by ingestion of 0.5-2 mg) is due to its ability to block voltage-gated sodium channels. Although several bacterial species (among these Vibrio sp.) have been linked to its synthesis, the biogenic origin and biosynthesis is unclear. One hypothesis is that TTX production occurs in a symbiotic relationship with its host, in this case the ribbon worm [3]. We have made significant effort to identify TTX in a setup for production through the cultivation of Vibrio alginolyticus in nutrient broth infused with mucus from the ribbon worm Lineus longissimus. Toxicity was demonstrated by fraction injections into shore crabs, but no TTX was found, and it could be shown conclusively that toxicity was unrelated to TTX and the Vibrio culture itself, and rather a constituent of the ribbon worm mucus [4]. The following studies led us to the discovery of a new class of peptides, the alpha-nemertides, in the mucus of the ribbon worms, which could be directly linked to the toxic effects. A literature review of the available evidence for TTX in ribbon worms show that the evidence in most cases are indirect, although notable exceptions exist. This points to the necessity to further investigate the presence and roles of TTX and alpha-nemertides in ribbon worms.

    Eating difficulties, nutrition, meal preferences and experiences among elderly - a literature overview from a Scandinavian context2015In: Journal of Food Research, ISSN 1927-0887, E-ISSN 1927-0895, Vol. 4, no 1, p. 22-37Article in journal (Refereed)
    Abstract [en]

    The risk of malnutrition increases with ageing, resulting in poorer health and higher risk of disease. Eating difficulties are important risk factors for malnutrition. Moreover, independence in relation to food and meals is highly rated by the elderly and has been associated with health and well-being. The purpose of this literature overview was to provide insights into nutritional status, food choice and preferences as well as the meal situations of home-living elderly (65+) people with motoric eating difficulties focusing on Scandinavia. The overall aim is to support independence and to prevent malnutrition. Nutritional status in the elderly was found to be negatively influenced by motoric eating difficulties including problems with manipulating food on the plate and transporting food to the mouth. Motoric eating difficulties may result in practical simplifications such as use of pre-prepared meals, less advanced cooking, and omission of certain meal constituents in order to avoid e.g. mismanagement and spillage. Eating difficulties are often accompanied by feelings of guilt and shame. Choosing smaller portions, reducing the number of eating episodes and not cooking independently have been associated with a higher risk of malnutrition. The nutritional effects of eating difficulties may be exacerbated by diminished chemosensory functions. Furthermore, both past and present food preferences should be considered in order to meet nutritional needs and meal satisfaction. Development of refined and socially accepted eating aids, in combination with tasty and nutritious products, is important in order to promote healthy and independent living among home-living elderly with motoric eating difficulties.

    Molecular Motor Propelled Filaments Reveal Light-Guiding in Nanowire Arrays for Enhanced Biosensing2014In: Nano letters (Print), ISSN 1530-6984, E-ISSN 1530-6992, Vol. 14, no 2, p. 737-742Article in journal (Refereed)
    Abstract [en]

    Semiconductor nanowire arrays offer significant potential for biosensing applications with optical read-out due to their high surface area and due to the unique optical properties of one-dimensional materials. A challenge for optical read-out of analyte-binding to the nanowires is the need to efficiently collect and detect light from a three-dimensional volume. Here we show that light from fluorophores attached along Several mu m long vertical Al2O3 coated gallium phosphide nanowires couples into the wires, is guided along them and emitted at the tip. This enables effective collection of light emitted by fluorescent analytes located at different focal planes along the nanowire. We unequivocally demonstrate the light-guiding effect using a novel method whereby the changes in emitted fluorescence intensity are observed when fluorescent cytoskeletal filaments are propelled by molecular motors along the wires. The findings are discussed in relation to nanobiosensor developments, other nanotechnological applications, and fundamental studies of motor function.

    The alpha-defensin salt-bridge induces backbone stability to facilitate folding and confer proteolytic resistance2012In: Amino Acids, ISSN 0939-4451, E-ISSN 1438-2199, Vol. 43, no 4, p. 1471-1483Article in journal (Refereed)
    Abstract [en]

    Salt-bridge interactions between acidic and basic amino acids contribute to the structural stability of proteins and to protein-protein interactions. A conserved salt-bridge is a canonical feature of the alpha-defensin antimicrobial peptide family, but the role of this common structural element has not been fully elucidated. We have investigated mouse Paneth cell alpha-defensin cryptdin-4 (Crp4) and peptide variants with mutations at Arg(7) or Glu(15) residue positions to disrupt the salt-bridge and assess the consequences on Crp4 structure, function, and stability. NMR analyses showed that both (R7G)-Crp4 and (E15G)-Crp4 adopt native-like structures, evidence of fold plasticity that allows peptides to reshuffle side chains and stabilize the structure in the absence of the salt-bridge. In contrast, introduction of a large hydrophobic side chain at position 15, as in (E15L)-Crp4 cannot be accommodated in the context of the Crp4 primary structure. Regardless of which side of the salt-bridge was mutated, salt-bridge variants retained bactericidal peptide activity with differential microbicidal effects against certain bacterial cell targets, confirming that the salt-bridge does not determine bactericidal activity per se. The increased structural flexibility induced by salt-bridge disruption enhanced peptide sensitivity to proteolysis. Although sensitivity to proteolysis by MMP7 was unaffected by most Arg(7) and Glu(15) substitutions, every salt-bridge variant was degraded extensively by trypsin. Moreover, the salt-bridge facilitates adoption of the characteristic alpha-defensin fold as shown by the impaired in vitro refolding of (E15D)-proCrp4, the most conservative salt-bridge disrupting replacement. In Crp4, therefore, the canonical alpha-defensin salt-bridge facilitates adoption of the characteristic alpha-defensin fold, which decreases structural flexibility and confers resistance to degradation by proteinases.

    Rational Design of Biomimetic Molecularly Imprinted Materials: Theoretical and Computational Strategies for Guiding Nanoscale Structured Polymer Development2011In: Analytical and Bioanalytical Chemistry, ISSN 1618-2642, E-ISSN 1618-2650, Vol. 400, p. 1771-1786Article, review/survey (Refereed)
    Abstract [en]

    In principle, molecularly imprinted polymer science and technology provides a means for ready access to nano-structured polymeric materials of predetermined selectivity. The versatility of the technique has brought it to the attention of many working with the development of nanomaterials with biological or biomimetic properties for use as therapeutics or in medical devices. Nonetheless, the further evolution of the field necessitates the development of robust predictive tools capable of handling the complexity of molecular imprinting systems. The rapid growth in computer power and software over the past decade has opened new possibilities for simulating aspects of the complex molecular imprinting process. We present here a survey of the current status of the use of in silico-based approaches to aspects of molecular imprinting. Finally, we highlight areas where ongoing and future efforts should yield information critical to our understanding of the underlying mechanisms sufficient to permit the rational design of molecularly imprinted polymers.

    Synthesis and ligand recognition of paracetamol selective polymers: semi-covalent versus non-covalent molecular imprinting.2009In: Organic and biomolecular chemistry, ISSN 1477-0520, E-ISSN 1477-0539, Vol. 7, p. 3148-3155Article in journal (Refereed)
    Abstract [en]

    Three molecular imprinting strategies, each based upon a series of ethylene glycol dimethacrylate (EGDMA) cross-linked co-polymers, have been used to produce materials selective for the commonly used analgesic and antipyretic agent paracetamol (p-acetaminophen or 4-acetamidophenol) (1). The polymers were synthesised using either a semi-covalent imprinting strategy based upon 4-acetamidophenyl-(4-vinylphenyl) carbonate (4) or a non-covalent strategy based on methacrylic acid (MAA) as the functional monomer, or by employing a combination of these strategies. Radioligand binding studies demonstrated low template affinity in polymers offering only a single electrostatic interaction point for recognition via the phenolic residue in the template, whereas binding was substantially increased upon the introduction of a second binding mode, namely interaction at the acetamide moiety. HPLC analyses revealed no imprinting effect in the purely semi-covalent system, and only a minor effect in the purely non-covalent systems. However, a pronounced imprinting effect was demonstrated for polymers prepared by a combination of semi-covalent and non-covalent imprinting. This study illustrates a limitation of both the non-covalent and the semi-covalent strategies when it comes to achieving imprinted selectivity for small and poorly functionalised templates such as paracetamol. Parallels with conclusions from studies with antibodies are discussed.
