Rätt att bo kvar : en handbok i organisering mot hyreshöjningar och gentrifiering
- 2016
-
Book (other academic/artistic)abstract
- Det här är en handbok som skrivits för att användas praktiskt i kampen om hyresrättens framtid. Boken har växt fram ur gemensamma erfarenheter av att ta strid mot renoveringar med höga hyreshöjningar som följd. Det har gett oss både kunskaper om lokal organisering och en övertygelse om vikten av att hyresgäster ska ha rätt till att påverka framtiden i de bostadsområden de bor i. De senaste åren har vi kunnat se hur hyreslägenheter renoveras med omfattande hyreshöjningar som följd. Konsekvenserna har blivit att många hyresgäster har tvingats flytta, ibland från bostadsområden de bott i under lång tid, då de inte längre har råd att betala hyran. Om inte hyresgäster går samman och kräver sina rättigheter kommer inget förändras och flera tusentals människor tvingas flytta. Den här handboken ska användas som ett praktiskt verktyg för lokal organisering. Vi som har gjort den här boken är engagerade i olika rörelser, några av oss är också forskare med inriktning mot bostad- spolitik och stadsutveckling. Boken har tillkommit genom en kollektiv process, där många varit inblandade för att bidra med sina erfarenheter och perspektiv. En lista med alla medverkande inklusive de rörelser som står bakom den här boken finns lägst bak.

The draft genome of the microscopic Nemertoderma westbladi sheds light on the evolution of Acoelomorpha genomes
- 2023

Journal article (peer-reviewed)abstract
- Background: Xenacoelomorpha is a marine clade of microscopic worms that is an important model system for understanding the evolution of key bilaterian novelties, such as the excretory system. Nevertheless, Xenacoelomorpha genomics has been restricted to a few species that either can be cultured in the lab or are centimetres long. Thus far, no genomes are available for Nemertodermatida, one of the group’s main clades and whose origin has been dated more than 400 million years ago.Methods: DNA was extracted from a single specimen and sequenced with HiFi following the PacBio Ultra-Low DNA Input protocol. After genome assembly, decontamination, and annotation, the genome quality was benchmarked using two acoel genomes and one Illumina genome as reference. The gene content of three cnidarians, three acoelomorphs, four deuterostomes, and eight protostomes was clustered in orthogroups to make inferences of gene content evolution. Finally, we focused on the genes related to the ultrafiltration excretory system to compare patterns of presence/absence and gene architecture among these clades.Results: We present the first nemertodermatid genome sequenced from a single specimen of Nemertoderma westbladi. Although genome contiguity remains challenging (N50: 60 kb), it is very complete (BUSCO: 80.2%, Metazoa; 88.6%, Eukaryota) and the quality of the annotation allows fine-detail analyses of genome evolution. Acoelomorph genomes seem to be relatively conserved in terms of the percentage of repeats, number of genes, number of exons per gene and intron size. In addition, a high fraction of genes present in both protostomes and deuterostomes are absent in Acoelomorpha. Interestingly, we show that all genes related to the excretory system are present in Xenacoelomorpha except Osr, a key element in the development of these organs and whose acquisition seems to be interconnected with the origin of the specialised excretory system.Conclusion: Overall, these analyses highlight the potential of the Ultra-Low Input DNA protocol and HiFi to generate high-quality genomes from single animals, even for relatively large genomes, making it a feasible option for sequencing challenging taxa, which will be an exciting resource for comparative genomics analyses.

ASXL1 mutations, previous vascular complications and age at diagnosis predict survival in 85 WHO-defined polycythaemia vera patients
- 2020

In: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 189:5, s. 913-919

Journal article (peer-reviewed)abstract
- Polycythaemia vera (PV) patients have an overall comparatively favourable prognosis, but disease progression is very heterogeneous and life-threatening thrombosis and bleedings are frequent complications in untreated disease. Moreover, transformation to more severe secondary myelofibrosis and acute myeloid leukaemia can occur. The aim of this study was to identify gene mutations that could be used together with clinical data as prognostic markers to guide treatment decisions in PV patients. A well-characterized WHO-defined cohort of PV patients was used. Clinical data and blood values were evaluated and a myeloid sequencing panel was used to screen for additional mutations other than the diagnostic JAK2 V617F and JAK2 exon 12 mutations. In 78% of the PV patients, at least one mutation additional to JAK2 V617F was detected. Additional mutations in genes coding for epigenetic modifiers, like TET2, DNMT3A and ASXL1, were most frequent. When correlated to overall survival, mutations in ASXL1 were significantly associated with inferior survival. In an attempt to obtain prognostic guidance in a larger number of patients, the presence of ASXL1 mutations was combined with age and vascular complications prior to diagnosis. Based on these data we were able to define three risk groups that predicted survival.

Journal article (peer-reviewed)abstract
- ObjectivesBacterial infections are common and a major cause of morbidity and mortality in multiple myeloma (MM). We have investigated the function of polymorphonuclear leukocyte (PMN), the immune system's first line of defense against bacteria, in peripheral blood (PB) and bone marrow (BM) samples from patients with newly diagnosed MM (NDMM), smoldering MM (SMM), monoclonal gammopathy of undetermined significance (MGUS) and healthy controls.MethodsPhagocytosis and oxidative burst in PMN cells from patients and healthy donors were investigated using PhagoTest and PhagoBurst assay.ResultsPMN from NDMM, SMM, and MGUS patients had reduced phagocytosis and oxidative burst ability compared with healthy controls. The dysfunction was most prominent in BM samples from MM, SMM, and MGUS patients. Importantly the reduced phagocytosis in MM patients was restored in patients on lenalidomide therapy. Consistently the ability of Escherichia coli stimulated oxidative burst in BM was reduced for the MM, SMM, and MGUS cohort in contrast to the healthy controls and the patients on lenalidomide treatment.ConclusionOur results show that MM patients have neutrophil dysfunction that could contribute to susceptibility for bacterial infections and that lenalidomide therapy was associated with restored PMN function.

A New Mouse Model That Spontaneously Develops Chronic Liver Inflammation and Fibrosis
- 2016
-
In: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 11:7
-
Journal article (peer-reviewed)abstract
- Here we characterize a new animal model that spontaneously develops chronic inflammation and fibrosis in multiple organs, the non-obese diabetic inflammation and fibrosis (N-IF) mouse. In the liver, the N-IF mouse displays inflammation and fibrosis particularly evident around portal tracts and central veins and accompanied with evidence of abnormal intrahepatic bile ducts. The extensive cellular infiltration consists mainly of macrophages, granulocytes, particularly eosinophils, and mast cells. This inflammatory syndrome is mediated by a transgenic population of natural killer T cells (NKT) induced in an immunodeficient NOD genetic background. The disease is transferrable to immunodeficient recipients, while polyclonal T cells from unaffected syngeneic donors can inhibit the disease phenotype. Because of the fibrotic component, early on-set, spontaneous nature and reproducibility, this novel mouse model provides a unique tool to gain further insight into the underlying mechanisms mediating transformation of chronic inflammation into fibrosis and to evaluate intervention protocols for treating conditions of fibrotic disorders.

The immunomodulatory quinoline-3-carboxamide paquinimod reverses established fibrosis in a novel mouse model for liver fibrosis
- 2018
-
In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 13:9
-
Journal article (peer-reviewed)abstract
- Quinoline-3-carboxamides (Q substances) are small molecule compounds with anti-inflammatory properties. In this study, we used one of these substances, Paquinimod, to treat a novel model for chronic liver inflammation and liver fibrosis, the NOD-Inflammation Fibrosis (N-IF) mouse. We show that treatment of N-IF mice significantly reduced inflammation and resulted in the regression of fibrosis, even when the treatment was initiated after onset of disease. The reduced disease phenotype was associated with a systemic decrease in the number and reduced activation of disease-promoting transgenic natural killer T (NKT)-II cells and their type 2-cytokine expression profile. Paquinimod treatment also led to a reduction of CD115+ Ly6Chi monocytes and CD11b+ F4/80+ CD206+ macrophages.

- INTRODUCTION :Cardiovascular disease (CVD) is a major cause of premature mortality among Systemic lupus erythematosus (SLE) patients. Many studies have measured and evaluated risk factors for premature subclinical atherosclerosis, but few studies are prospective and few have evaluated risk factors for hard endpoints, i.e. clinically important cardiovascular events (CVE). We investigated the impact of traditional and lupus associated risk factors for the first ever CVE in a longitudinal cohort of SLE patients.METHODS : A total of 182 SLE patients (mean age 43.9 years) selected to be free of CVE were included. Cardiovascular and autoimmune biomarkers were measured on samples collected after overnight fasting at baseline. Clinical information was collected at baseline and at follow up. End point was the first ever CVE (ischemic heart, cerebrovascular or peripheral vascular disease or death due to CVD). Impact of baseline characteristics/biomarkers on the risk of having a first CVE was evaluated with Cox regression.RESULTS :Follow up was 99.5% after a mean time of 8.3 years. Twenty-four patients (13%) had a first CVE. In age-adjusted Cox regression, any positive antiphospholipid antibody (aPL), elevated markers of endothelial activation (von Willebrand factor (vWf), soluble vascular cellular adhesion molecule-1 (sVCAM-1)) and fibrinogen predicted CVEs. Of SLE manifestations, arthritis, pleuritis and previous venous occlusion were positively associated with future CVEs while thrombocytopenia was negatively associated. Among traditional risk factors only age and smoking were significant predictors. In a multivariable Cox regression model age, any positive aPL, vWf and absence of thrombocytopenia were all predictors of the first CVE.CONCLUSIONS : In addition to age, positive aPL, biomarkers indicating increased endothelial cell activity/damage, and absence of thrombocytopenia were independent predictors of CVEs in this prospective study. Our results indicate that activation of the endothelium and the coagulation system are important features in SLE related CVD. Furthermore, we observed that the risk of CVEs seems to differ between subgroups of SLE patients.

Deficiency in plasmacytoid dendritic cells and type I interferon signalling prevents diet-induced obesity and insulin resistance in mice

Journal article (peer-reviewed)abstract
- Aims/hypothesis: Obesity is associated with glucose intolerance and insulin resistance and is closely linked to the increasing prevalence of type 2 diabetes. In mouse models of diet-induced obesity (DIO) and type 2 diabetes, an increased fat intake results in adipose tissue expansion and the secretion of proinflammatory cytokines. The innate immune system not only plays a crucial role in obesity-associated chronic low-grade inflammation but it is also proposed to play a role in modulating energy metabolism. However, little is known about how the modulation of metabolism by the immune system may promote increased adiposity in the early stages of increased dietary intake. Here we aimed to define the role of type I IFNs in DIO and insulin resistance. Methods: Mice lacking the receptor for IFN-α (IFNAR−/−) and deficient in plasmacytoid dendritic cells (pDCs) (B6.E2-2fl/fl.Itgax-cre) were fed a diet with a high fat content or normal chow. The mice were analysed in vivo and in vitro using cellular, biochemical and molecular approaches. Results: We found that the development of obesity was inhibited by an inability to respond to type I IFNs. Furthermore, the development of obesity and insulin resistance in this model was associated with pDC recruitment to the fatty tissues and liver of obese mice (a 4.3-fold and 2.7-fold increase, respectively). Finally, we demonstrated that the depletion of pDCs protects mice from DIO and from developing obesity-associated metabolic complications. Conclusions/interpretation: Our results provide genetic evidence that pDCs, via type I IFNs, regulate energy metabolism and promote the development of obesity.
