  1. 1. Asymmetric Synthesis of C-Glycosylated Amino Acids : Incorporation in Collagen Glycopeptides and Evaluation in a Model for Rheumatoid Arthritis

    Author : Tomas Gustafsson; Jan Kihlberg; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Total synthesis; stereoselective synthesis; chiral glycine templates; Evan’s alkylation; asymmetric hydrogenation; alpha-amino acid synthesis; C-glycoside; rheumatoid arthritis; MHC; T cell; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes stereoselective syntheses of four amino acids, three of which are C-glycosidic analogues of glycosylated amino acids. The overall goal of the project was to probe the interactions between MHC molecules, glycopeptide antigens and T cell receptors, that are essential for development of collagen induced arthritis.

  2. 2. The role of leucine-rich repeat glycoproteins/proteoglycans in the assembly of collagen matrices

    Author : Liz Svensson; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; Skelett; decorin; Collagen; fibromodulin; extracellular matrix; lumican; collagen fibrillogenesis; Skeleton; rheumatology locomotion; muscle system; Biochemistry; Biokemi; Metabolism;

    Abstract : The properties of different connective tissues depend on the synthesis and assembly of macromolecular structures composed of collagen and other extracellular matrix components. Mechanisms modulating these events play important roles in the formation of a functional tissue. READ MORE

  3. 3. The MHC-glycopeptide-T cell interaction in collagen induced arthritis : a study using glycopeptides, isosteres and statistical molecular design in a mouse model for rheumatoid arthritis

    Author : Lotta Holm; Jan Kihlberg; Morten Grötli; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Rheumatoid arthritis; collagen; T-cell; class II MHC; solid phase peptide synthesis; glycopeptide; peptide isostere; PCA; statistical molecular design; PLS; QSAR; sequence binding motif; Organic chemistry; Organisk kemi;

    Abstract : Rheumatoid arthritis (RA) is an autoimmune disease affecting approximately 1% of the population in the western world. It is characterised by a tissue specific attack of cartilage in peripheral joints. Collagen induced arthritis (CIA) is one of the most commonly used animal models for (RA), with similar symptoms and histopathology. READ MORE
