  2. 1. The release of histone proteins from cells via extracellular vesicles

    Author : Uma Muthukrishnan; Jonathan Gilthorpe; Miles Trupp; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone; extracellular vesicles; exosomes; extracellular histones extracellular DNA; cellular stress; proteomics; ESCRT complex; Lrrn1; mid-hindbrain organizer; ovarian cancer; ascites;

    Abstract : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. READ MORE

  4. 2. Imaging and Spectroscopic Mapping of Blood Cell Activity : Nanoparticles and Neutrophil Extracellular Traps

    Author : Kalle Bunnfors; Kajsa Uvdal; Caroline Brommesson; Christelle Prinz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrophils; Neutrophil extracellular traps; fluorescence; XPS; TEM;

    Abstract : Imaging and visualization of cell activity when exposed to nanomaterial are of main importance, when investigating biological response to a wide range of biomaterials from medical implants to smart nanoprobes. The ability to provide molecular and chemical information with spatial resolution in the region of sub-µm leads to increased insight and understanding of these biological challenges. READ MORE

  5. 3. Epigenetic influence on cardiovascular protective mechanisms in vivo: explorations of t-PA release and extracellular vesicle genetic content

    Author : Kristina Svennerholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial ischemia; epigenetics; histone deactylase inhibition; t-PA; extracellular vesicles; ischemic preconditioning;

    Abstract : ABSTRACT Background: Ischemic heart disease is one of the leading causes of death globally. This thesis explores endogenous mechanisms protecting against myocardial ischemia in context of epigenetics (changes in gene activity not caused by changes in DNA sequences). READ MORE

  6. 4. Granulocyte Adhesion to Matrix Proteins and the Effect on the Release of Granule Proteins : Development of a Simple Method and its Application in Experimental and Clinical Studies

    Author : Xiaoyan Xu; Joachim Lundahl; Uppsala universitet; []
    Keywords : Medical sciences; Eosinophils; Neutrophils; Adhesion; Release of ECP; Extracellular matrix proteins; Granulocytes; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Abstract : Granulocyte adhesion and release of their granule proteins are key steps during selective accumulation of a certain cell to an inflammatory site. Eosinophils are specifically recruited to sites of allergic inflammation and parasitic infection, whereas neutrophil influx predominates in bacterial infection and rheumatoid arthritis. READ MORE

  7. 5. Tryptophan-related Neurotransmission in the Brain: Disturbances Associated with Experimental Hepatic Encephalopathy

    Author : Peter B F Bergqvist; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tetrodotoxin; serotonin; release; rat; quinolinic acid; potassium; chloroamphetamine; noradrenaline; neurotransmission; microdialysis; hepatic encephalopathy; fenfluramine; drug safety; dopamine; coma; citalopram; ammonia; calcium; brain; tryptophan; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. READ MORE
