Tidskriftsartikel (refereegranskat)abstract
- Previously, apoE-derived ABCA1 agonist peptides have been shown to possess anti-atherosclerotic and possibly antidiabetic properties. Here we assessed the in vitro and in vivo actions of a second generation of ABCA1 peptide agonists, CS6253 and T6991-2, on glucose homeostasis. The results show that these two peptides improve glucose tolerance in a prediabetic diet-induced obesity mouse model by enhancing insulin secretion. It was further demonstrated that T6991-2 also improved glucose tolerance in leptin-deficient (ob/ob) mice. CS6253 increased insulin secretion both under basal conditions and in response to high glucose stimulation in pancreatic INS-1 β-cells rendered leptin receptor deficient with specific siRNA. Additional in vitro cell studies suggest that the CS6253 agonist attenuates hepatic gluconeogenesis and glucose transport. It also potentiates insulin-stimulated glucose uptake and utilization. These observed anti-diabetic actions suggest additional benefits of the CS6253 and T6991-2 ABCA1 peptide agonists for cardiovascular disease beyond their direct anti-atherosclerosis properties previously described.

Ulriksdals slott under 350 år
- 1995
-
Rapport (populärvet., debatt m.m.)abstract
- Studierna har utgått från Ulriksdals slott, uppfört av Jacob De la Gardie för 350 år sedan. Som kungligt slott har Ulriksdal genomgått ombyggnader under 1600 - och 1700-talet, men präglas idag mest av Karl XVs omfattande omdaning på 1850-talet och Gustav VI Adolfs lika genomgripande förändringar på 1920-talet.Slottet har bjudit på rika studiemöjligheter av stilideal, planlösning, interiörgestaltning, snickerikultur och stormtekniska system från hela 350-årsperioden. Genom noggranna uppmätningar och inventeringar på plats kopplade till arkivstudier har slottets komplicerade förändringshistoria kunnat analyseras,

Ultrastructural characterisation of the hydroxyapatite–coated pedicle screw and human bone interface
- 2012
-
Ingår i: International Journal of Nano and Biomaterials. - 1752-8933 .- 1752-8941. ; 4:1, s. 1-11

Tidskriftsartikel (refereegranskat)abstract
- The early fixation of pedicle screws is crucial for improving spinal stabilisation. Firm and immediate fixation between pedicle screws and bone prevents aseptic loosening and implant failure. Coating with hydroxyapatite is a possible method to improve the fixation of metallic implants in bone. In this study, scanning transmission electron microscopy (STEM) has been used to investigate the ultrastructure of the plasma–sprayed hydroxyapatite coating and human bone interface in detail. Focused ion beam sample preparation also enabled the investigation of the bone–lacunae interface. An intimate contact and elemental analysis between bone and HA coatings suggests bioactive fixation. Therefore, coating with hydroxyapatite leads to enhanced biocompatibility at the ultrastructural level and may lead to improved early and long–term fixation of pedicle screws.

Dairy Consumption and Body Mass Index Among Adults : Mendelian Randomization Analysis of 184802 Individuals from 25 Studies
- 2018
-
Ingår i: Clinical Chemistry. - : Oxford University Press (OUP). - 0009-9147 .- 1530-8561. ; 64:1, s. 183-191
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Associations between dairy intake and body mass index (BMI) have been inconsistently observed in epidemiological studies, and the causal relationship remains ill defined.METHODS: We performed Mendelian randomization (MR) analysis using an established dairy intake-associated genetic polymorphism located upstream of the lactase gene (LCT-13910 C/T, rs4988235) as an instrumental variable (IV). Linear regression models were fitted to analyze associations between (a) dairy intake and BMI, (b) rs4988235 and dairy intake, and (c) rs4988235 and BMI in each study. The causal effect of dairy intake on BMI was quantified by IV estimators among 184802 participants from 25 studies.RESULTS: Higher dairy intake was associated with higher BMI (β = 0.03 kg/m2 per serving/day; 95% CI, 0.00–0.06; P = 0.04), whereas the LCT genotype with 1 or 2 T allele was significantly associated with 0.20 (95% CI, 0.14–0.25) serving/day higher dairy intake (P = 3.15 × 10−12) and 0.12 (95% CI, 0.06–0.17) kg/m2 higher BMI (P = 2.11 × 10−5). MR analysis showed that the genetically determined higher dairy intake was significantly associated with higher BMI (β = 0.60 kg/m2 per serving/day; 95% CI, 0.27–0.92; P = 3.0 × 10−4).CONCLUSIONS: The present study provides strong evidence to support a causal effect of higher dairy intake on increased BMI among adults.

Assessing Low Carbon Transitions : A Conceptual Model
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The present report presents a conceptual assessment model or framework for policy relevant analysis of low carbon transitions. The aim of the study is not to present specific guidelines for how to design assessments of low carbon transitions, but rather to give food for thought on aspects that should be regarded in the design process. The exact design would then depend on the purpose of the assessment, the scope and priorities set for the assessment, and the resources (personal and financial) available for the assessments.We find that there are at least three elements of an assessment model that are important to provide policy relevant knowledge: i) monitoring, ii) policy evaluation, and iii) domain knowledge building processes, including research. Monitoring is here understood as a process that is intended to inform whether society is on track on meeting set-up political priorities. Policy evaluation concentrates on the effects of low carbon transition policies and effects of other policies. Domain knowledge building through research and other processes is important both for identifying relevant assessment criteria and designing monitoring systems, as well as for policy evaluations. A domain knowledge base can include knowledge of i) drivers and barriers for low carbon transitions, ii) the sustainability of various technologies, policies and practices, iii) previous policy experiences, and iv) contextual knowledge of the market, actors, mitigation technologies and pathways, etc. in various sectors. This information and background knowledge will help inform how policies can be redesigned for overcoming the barriers and enable change in various contexts while safeguarding that the changes are not in conflict with other key societal goals and sustainability aspects. Monitoring can cover direct outcomes such as greenhouse gas emissions or diffusion of low carbon technologies. But with a long-term transitions perspective it is also important to look into the preparedness for change with regard to existence of factors such as visions and expectations, knowledge, feasible policies and policy instruments (taking into account stringency as well as coverage and policy coherence), societal norms, innovation networks, or the readiness of key technologies.Evaluation of policies can in turn cover several aspects beyond policy relevance and effectiveness including synergies and conflicts with other objectives. It could also evaluate the consistency of targets with overarching objectives as well as specific strategies, policy instruments or policy packages. In the conceptual assessment model, policy adjustments are expected to be informed by the monitoring process regarding what is needed and by policy evaluation with regard to what works. Together these processes can inform on how both the stringency and the design of policies could be developed over time.

Miljöstyrningsrådets tankesmedja för transformativa lösningar i inköp och upphandling
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Transformativa upphandlingar är inget upphandlingsförfarande som finns beskrivet och reglerat i direktiv och lagar. Det transformativa inköpsarbetet är ett långsiktigt arbete som behöver påbörjas långt innan upphandlaren skriver ihop förfrågningsunderlaget, med andra ord handlar det om ett strategiskt inköpsarbete.Tankesmedjan är ett initiativ där individer från kommuner, landsting, statliga myndigheter, akademi och andra relevanta organisationer samlas för att undersöka hur dagens globala utmaningar kan vändas till möjligheter genom transformativa lösningar inom offentlig upphandling och inköp. Detta sker för att bidra till att uppnå de långsiktiga hållbarhetsmål som formulerats på internationell nivå, EU-nivå, nationell nivå och även i allt större utsträckning på lokal nivå.Tankesmedjans arbete med transformativa lösningar i inköp och upphandling utgår från den upphandlande organisationens behov i förhållande till hållbar utveckling.Tankesmedjans syfte är att se till alla aktiviteter som tillfredsställer organisationens behov av transformativa lösningar. Det kan vara lösningar som leder till innovationer men perspektivet är inte avgränsat till innovationer utan är ett helhetsperspektiv på alla möjliga lösningar.Tankesmedjan initierades och koordinerades av Miljöstyrningsrådet från början av 2013 och fram till Miljöstyrningsrådets nedläggning i juli 2014.Denna skrift är inte en vetenskaplig rapport och inte heller en utredning, det är snarare en stafettpinne. Den handlar om vad Tankesmedjan arbetat med under knappa omständigheter och hur vägen framåt för tankesmedjans fortsatta arbete ser ut nu när Tankesmedjan lämnas över till nästa aktör.Kanske kan skriften även tjäna som inspirationskälla till alla köpande organisationer att söka transformativa lösningar i inköp och upphandling.

Genome-wide single cell annotation of the human protein-coding genes
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- An important quest for the life science community is to deliver a complete annotation of the human building-blocks of life, the genes and the proteins. Here, we report on a genome-wide effort to annotate all protein-coding genes based on single cell transcriptomics data representing all major tissues and organs in the human body, integrated with data from bulk transcriptomics and antibody-based tissue profiling. Altogether, 25 tissues have been analyzed with single cell transcriptomics resulting in genome-wide expression in 444 single cell types using a strategy involving pooling data from individual cells to obtain genome-wide expression profiles of individual cell type. We introduce a new genome-wide classification tool based on clustering of similar expression profiles across single cell types, which can be visualized using dimensional reduction maps (UMAP). The clustering classification is integrated with a new “tau” score classification for all protein-coding genes, resulting in a measure of single cell specificity across all cell types for all individual genes. The analysis has allowed us to annotate all human protein-coding genes with regards to function and spatial distribution across individual cell types across all major tissues and organs in the human body. A new version of the open access Human Protein Atlas (www.proteinatlas.org) has been launched to enable researchers to explore the new genome-wide annotation on an individual gene level.

Spatiotemporal dissection of the cell cycle with single-cell proteogenomics

Tidskriftsartikel (refereegranskat)abstract
- Spatial and temporal variations among individual human cell proteomes are comprehensively mapped across the cell cycle using proteomic imaging and transcriptomics. The cell cycle, over which cells grow and divide, is a fundamental process of life. Its dysregulation has devastating consequences, including cancer(1-3). The cell cycle is driven by precise regulation of proteins in time and space, which creates variability between individual proliferating cells. To our knowledge, no systematic investigations of such cell-to-cell proteomic variability exist. Here we present a comprehensive, spatiotemporal map of human proteomic heterogeneity by integrating proteomics at subcellular resolution with single-cell transcriptomics and precise temporal measurements of individual cells in the cell cycle. We show that around one-fifth of the human proteome displays cell-to-cell variability, identify hundreds of proteins with previously unknown associations with mitosis and the cell cycle, and provide evidence that several of these proteins have oncogenic functions. Our results show that cell cycle progression explains less than half of all cell-to-cell variability, and that most cycling proteins are regulated post-translationally, rather than by transcriptomic cycling. These proteins are disproportionately phosphorylated by kinases that regulate cell fate, whereas non-cycling proteins that vary between cells are more likely to be modified by kinases that regulate metabolism. This spatially resolved proteomic map of the cell cycle is integrated into the Human Protein Atlas and will serve as a resource for accelerating molecular studies of the human cell cycle and cell proliferation.

Streptococcal M protein promotes IL-10 production by cGAS-independent activation of the STING signaling pathway

Tidskriftsartikel (refereegranskat)abstract
- From an evolutionary point of view a pathogen might benefit from regulating the inflammatory response, both in order to facilitate establishment of colonization and to avoid life-threatening host manifestations, such as septic shock. In agreement with this notion Streptococcus pyogenes exploits type I IFN-signaling to limit detrimental inflammation in infected mice, but the host-pathogen interactions and mechanisms responsible for induction of the type I IFN response have remained unknown. Here we used a macrophage infection model and report that S. pyogenes induces anti-inflammatory IL-10 in an M protein-dependent manner, a function that was mapped to the B- and C-repeat regions of the M5 protein. Intriguingly, IL-10 was produced downstream of type I IFN-signaling, and production of type I IFN occurred via M protein-dependent activation of the STING signaling pathway. Activation of STING was independent of the cytosolic double stranded DNA sensor cGAS, and infection did not induce detectable release into the cytosol of either mitochondrial, nuclear or bacterial DNA–indicating DNA-independent activation of the STING pathway in S. pyogenes infected macrophages. These findings provide mechanistic insight concerning how S. pyogenes induces the type I IFN response and identify a previously unrecognized macrophage-modulating role for the streptococcal M protein that may contribute to curb the inflammatory response to infection.

A European industrial development policy for prosperity and zero emissions

Konferensbidrag (refereegranskat)abstract
- The objective of this paper is to outline and discuss the key elements of an EU industrial development policy consistent with the Paris Agreement. We also assess the current EU Industrial Strategy proposal against these elements. The “well below 2 °C” target sets a clear limit for future global greenhouse gas emissions and thus strict boundaries for the development of future material demand, industrial processes and the sourcing of feedstock; industry must evolve to zero emissions or pay for expensive negative emissions elsewhere. An industrial policy for transformation to net-zero emissions must include attention to directed technological and economic structural change, the demand for emissions intensive products and services, energy and material efficiency, circular economy, electrification and other net-zero fuel switching, and carbon capture and use or storage (CCUS). It may also entail geographical relocation of key basic materials industries to regions endowed with renewable energy. In this paper we review recent trends in green industrial policy. We find that it has generally focused on promoting new green technologies (e.g., PVs, batteries, fuel cells and biorefineries) rather than on decarbonizing the emissions intensive basic materials industries, or strategies for handling the phase-out or repurposing of sunset industries (e.g., replacing fossil fuel feedstocks for chemicals). Based on knowledge about industry and potential mitigation options, and insights from economics, governance and innovation studies, we propose a framework for the purpose of developing and evaluating industrial policy for net-zero emissions. This framework recognizes the need for: directionality; innovation; creating lead markets for green materials and reshaping existing markets; building capacity for governance and change; coherence with the international climate policy regime; and finally the need for a just transition. We find the announced EU Industrial Strategy to be strong on most elements, but weak on transition governance approaches, the need for capacity building, and creating lead markets.

An industrial policy framework for transforming energy and emissions intensive industries towards zero emissions
- 2021

Tidskriftsartikel (refereegranskat)abstract
- The target of zero emissions sets a new standard for industry and industrial policy. Industrial policy in the twenty-first century must aim to achieve zero emissions in the energy and emissions intensive industries. Sectors such as steel, cement, and chemicals have so far largely been sheltered from the effects of climate policy. A major shift is needed, from contemporary industrial policy that mainly protects industry to policy strategies that transform the industry. For this purpose, we draw on a wide range of literatures including engineering, economics, policy, governance, and innovation studies to propose a comprehensive industrial policy framework. The policy framework relies on six pillars: directionality, knowledge creation and innovation, creating and reshaping markets, building capacity for governance and change, international coherence, and sensitivity to socio-economic implications of phase-outs. Complementary solutions relying on technological, organizational, and behavioural change must be pursued in parallel and throughout whole value chains. Current policy is limited to supporting mainly some options, e.g. energy efficiency and recycling, with some regions also adopting carbon pricing, although most often exempting the energy and emissions intensive industries. An extended range of options, such as demand management, materials efficiency, and electrification, must also be pursued to reach zero emissions. New policy research and evaluation approaches are needed to support and assess progress as these industries have hitherto largely been overlooked in domestic climate policy as well as international negotiations. Key policy insights Energy and emission intensive industries can no longer be complacent about the necessity of zero greenhouse gas (GHG) emissions. Zero emissions require profound technology and organizational changes across whole material value chains, from primary production to reduced demand, recycling and end-of-life of metals, cement, plastics, and other materials. New climate and industrial policies are necessary to transform basic materials industries, which are so far relatively sheltered from climate mitigation. It is important to complement technology R&D with the reshaping of markets and strengthened governance capacities in this emerging policy domain. Industrial transformation can be expected to take centre stage in future international climate policy and negotiations.

Tidskriftsartikel (refereegranskat)abstract
- Anti-neutrophil cytoplasmic antibody associated vasculitides (AAV) are conditions defined by an autoimmune small vessel inflammation. Dying neutrophils are found around the inflamed vessels and the balance between infiltrating neutrophils and macrophages is important to prevent autoimmunity. Here we investigate how sera from AAV patients may regulate macrophage polarization and function. Macrophages from healthy individuals were differentiated into M0, M1, M2a, M2b or M2c macrophages using a standardized protocol, and phenotyped according to their expression surface markers and cytokine production. These phenotypes were compared with those of macrophages stimulated with serum from AAV patients or healthy controls. While the healthy control sera induced a M0 macrophage, AAV serum promoted polarization towards the M2c subtype. No sera induced M1, M2a or M2b macrophages. The M2c subtype showed increased phagocytosis capacity compared with the other subtypes. The M2c polarization found in AAV is consistent with previous reports of increased levels of M2c-associated cytokines.

Tidskriftsartikel (refereegranskat)abstract
- Resolving the spatial distribution of the human proteome at a subcellular level can greatly increase our understanding of human biology and disease. Here we present a comprehensive image-based map of subcellular protein distribution, the Cell Atlas, built by integrating transcriptomics and antibody-based immunofluorescence microscopy with validation by mass spectrometry. Mapping the in situ localization of 12,003 human proteins at a single-cell level to 30 subcellular structures enabled the definition of the proteomes of 13 major organelles. Exploration of the proteomes revealed single-cell variations in abundance or spatial distribution and localization of about half of the proteins to multiple compartments. This subcellular map can be used to refine existing protein-protein interaction networks and provides an important resource to deconvolute the highly complex architecture of the human cell.

- Resolving the molecular details of proteome variation in the different tissues and organs of the human body will greatly increase our knowledge of human biology and disease. Here, we present a map of the human tissue proteome based on an integrated omics approach that involves quantitative transcriptomics at the tissue and organ level, combined with tissue microarray-based immunohistochemistry, to achieve spatial localization of proteins down to the single-cell level. Our tissue-based analysis detected more than 90% of the putative protein-coding genes. We used this approach to explore the human secretome, the membrane proteome, the druggable proteome, the cancer proteome, and the metabolic functions in 32 different tissues and organs. All the data are integrated in an interactive Web-based database that allows exploration of individual proteins, as well as navigation of global expression patterns, in all major tissues and organs in the human body.
