  1. 1. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa

    Författare :Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intraepithelial lymphocytes; alimentary tract; intestinal epithelium; gut luminal antigens; gingiva; γδ T cells; immunoelectron microscopy; cytokine mRNA; RT-PCR; extrathymic T cell maturation; RAG-1; periodontitis; mucosal immune system; CD4-CD8- αβ T cells; CD8 γδ T cells;

    Sammanfattning : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. LÄS MER

  3. 2. Dendritic cells in immune and gene therapy against cancer

    Författare :Andreas Lundqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dendritic cells; immunotherapy; gene therapy;

    Sammanfattning : Dendritic cells (DC) are extensively used for vaccine therapy due to their superior T cell stimulatory capacity. However, the modest therapeutic effects reported by most clinical trials using DC, together with the rapid developing field of DC biology suggests important considerations for improvement of the clinical outcome.

  4. 3. Numerical analysis of concrete elements strengthened with carbon fiber reinforced polymers

    Författare :Joakim Lundqvist; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Due to the growing number of ageing reinforced concrete structures such as buildings and bridges, there is an increasing interest in condition assessment and strengthening methods. Deterioration processes and demands for higher loads contribute to this interest. LÄS MER

  5. 4. Isolation, characterization and enzymatic hydrolysis of water-soluble wood polysaccharides

    Författare :Jon Lundqvist; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; size exclusion chromatography; beta-mannosidase; beta-mannanase; endoglucanase; ethyl hydoxyethyl cellulose; metabolism; Biokemi; Biochemistry; Metabolism; microwave irradiation; O-acetyl-galactoglucomannan; isolation;

    Sammanfattning : The need for new renewable products has enhanced the interest in cellulose and hemicellulose as raw material. The wood plant cell wall is a complex mixture of cellulose, hemicellulose, lignin and minor amounts of pectin, proteins and extractives. Several interactions between the compounds make them difficult to separate without modification. LÄS MER

  7. 5. Insights into structure and dynamics of the AAA+ motor of magnesium chelatase

    Författare :Joakim Lundqvist; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; biomathematics biometrics; Bioinformatics; medical informatics; Rhodobacter capsulatus; Tetrapyrrole; Mutants; Magnesium chelatase; Cryo-Electron microscopy single-particle 3D reconstruction; Chlorophyll biosynthesis; AAA proteins; ATPase; medicinsk informatik; biomatematik; Molecular biophysics; Molekylär biofysik; Natural science; Naturvetenskap;

    Sammanfattning : The insertion of Mg2+ into protoporphyrin IX represents the first committed step in the chlorophyll and bacteriochlorophyll biosynthetic pathways. The reaction is catalyzed by the multisubunit enzyme Mg-chelatase, which consists of three subunits, known as I (molecular weight ~40 kDa), D (~70 kDa), and H (~140 kDa). LÄS MER
