  1. 6. Exploitation of interactions with the neonatal Fc receptor to manipulate biological half-lives for therapeutic applications

    Författare :Shengze Yu; Torbjörn Gräslund; Mats Ohlin; KTH; []
    Nyckelord :Glioblastoma Multiforme GBM ; Prolacin Prl ; Prolacin receptor PrlR ; Prolactin antagonist PrlRA ; Albumin binding domain ABD ; serum albumin SA ; half-life extension; FcRn; Affibody; human growth hormone hGH ; immunoglobulin G IgG ; blocking; autoimmune disease; Bioteknologi; Biotechnology;

    Sammanfattning : Protein engineering provides powerful tools to create useful proteins with desired properties. In this thesis, rational design principles have been used for development of fusion proteins that can interact with the neonatal Fc receptor (FcRn) for potential medical applications. FcRn is widely expressed in the human body.

  2. 7. Protein stabilization. Some methods and mechanisms

    Författare :Maria Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER

  3. 8. Ghrelin and CART. Two new islet peptides. Expression, regulation and function

    Författare :Nils Wierup; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endokrinologi; sekretion; diabetologi; Endocrinology; secreting systems; diabetology; histology; endocrinology; islets; CART; Ghrelin cells; insulin secretion; type-2 diabetes; Ghrelin;

    Sammanfattning : Until recently, the islets of Langerhans were thought to harbour four main cell types characterised with respect to principal hormone product. Here we show that the novel hormone ghrelin is expressed in a fifth islet cell type, the islet ghrelin cell, in humans and rodents. LÄS MER

  4. 9. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

    Författare :Mikael Nilsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; VHb; Vitreoscilla hemoglobin; E. coli; Escherichia coli; separation; subunits; ribosomes; Asymmetrical flow field-flow fractionation; flow FFF; optimization; biotechnological production; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. LÄS MER

  5. 10. Poly(Lactide-co-Glycolide) in Controlled-Release Pharmaceuticals - Release Mechanisms

    Författare :Susanne Fredenberg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PLGA; Poly lactide-co-glycolide ; Release mechanism; Diffusion; Controlled Release; Degradation; Protein;

    Sammanfattning : Controlled-release formulations reduce the frequency of injections and better maintain plasma concentrations within the therapeutic window. Poly(D,L-lactide-co-glycolide) (PLG) is currently the most frequently used biodegradable polymer for this application. LÄS MER
