  1. 1. PNA and affinity protein tools for selective tumor targeting of radiopharmaceuticals

    Författare :Hanna Tano; Amelie Eriksson Karlström; Per-Åke Nygren; Dario Neri; KTH; []
    Nyckelord :Cancer therapy; targeted radionuclide therapy; affinity proteins; Affibody molecules; CD38; GRPR; HER2; nanobody; peptide; PNA; RM26; pretargeting; Cancerterapi; radionuklid terapi; affinitetsproteiner; affibody molekyler; CD38; GRPR; HER2; nanobody; peptid; PNA; RM26; pretargeting; Biotechnology; Bioteknologi;

    Sammanfattning : Targeted radiotherapy of cancer intends to selectively deliver cytotoxic radionuclides to tumor cells. Affinity proteins of various kinds are explored for this task, and depending on the affinity protein used, different challenges arise. LÄS MER

  3. 2. Synthesis of Aldehyde-Functionalized Building Blocks and Their Use for the Cyclization of Peptides : Applications to Angiotensin II

    Författare :Petra Johannesson; Rob M. J. Liskamp; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Synthesis; Aldehyde; Cyclization; Peptide; Angiotensin II; Ang II; Bioactive Conformation; Solid Phase Peptide Synthesis; Dimethyl Acetal; Farmaceutisk kemi; Syntes; Aldehyd; Cyklisering; Peptid; Bioaktiv konformation; Fast-fas peptidsyntes; Dimetylacetal; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Sammanfattning : This study addresses the issue of how to convert peptides into drug-like non- peptides with retained biological activities at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. LÄS MER

  4. 3. New Proteomics Methods and Fundamental Aspects of Peptide Fragmentation

    Författare :Mikhail Savitski; Roman Zubarev; Per Andren; David Fenyö; Uppsala universitet; []
    Nyckelord :Bioinformatics; Proteomics; Peptide fragmentation; Bioinformatik;

    Sammanfattning : The combination of collision-activated dissociation, (CAD) and electron capture dissociation, (ECD) yielded a 125% increase in protein identification. The S-score was developed for measuring the information content in MS/MS spectra. This measure made it possible to single out good quality spectra that were not identified by a search engine.

  5. 4. HLA class I maturation - in the presence and absence of tapasin

    Författare :Linda Geironson Ulfsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Human leukocyte antigen class I (HLA-I) molecules are present on all nucleated cells and present the cell content to cytotoxic T lymphocytes in the form of peptides. Maturation of HLA-I occurs in the endoplasmic reticulum and results in stable peptide-HLA-I complexes, in the presence of proper quality control. LÄS MER

  7. 5. The quality control of MHC class I antigen presentation

    Författare :Kajsa M Paulsson; Antigen presentation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperone; assembly; COPI; antigenic peptide; TAP; MHC; tapasin; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8+ T cells. The peptides are generated by proteasomes in the cytosol, then translocated across the membrane of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP). LÄS MER
