    Keywords : airway obstruction; antigen; capsaicin; epithelium; inflammatory mediators; sensory neurons; tube preparation; tachykinins; formoterol; histamine; presynaptic inhibition; in vitro; guinea pig; MEDICINE; MEDICIN;

    Abstract : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. READ MORE

  4. 7. Feedback Enhancement of Immune Responses by IgE, IgM, and IgG3 Antibodies

    Author : Zhoujie Ding; Birgitta Heyman; Eva Severinson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgE; IgM; IgG3; antibody responses; T-cell responses; antigen transportation; antigen presentation; complement; complement receptors 1 and 2; Immunologi; Immunology;

    Abstract : Antibodies can enhance or suppress the immune responses against their specific antigens. This phenomenon is known as antibody-mediated feedback regulation. We have studied the mechanisms underlying IgE-, IgM-, and IgG3-mediated enhancement of immune responses in mouse models using intravenous immunization. READ MORE

  5. 8. Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

    Author : Linn Stenfelt; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; P1 antigen; Sda antigen; A4GALT; B3GALNT2; glycosyltransferase; red blood cell; transfusion medicine;

    Abstract : Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. READ MORE

  6. 9. Characterization of Antigenic Properties and High Throughput Protein Purification

    Author : Johanna Steen; Sophia Hober; Mats Ohlin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high throughput; protein purification; sample preparation; antigen solubility; immunogenicity; epitope mapping; antigen design; Bioengineering; Bioteknik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : To understand the cellular processes, knowledge of the localization and function of proteins are essential. There are several high throughput ventures examining the human proteome. However, there are some bottlenecks in these ventures. For example the production and expression of soluble proteins for analysis. READ MORE

  7. 10. Dendritic cell interactions with Gram negative bacteria

    Author : Mattias Svensson; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; virology; Major histocompatibility complex molecules; Dendritic cells; Gram negative bacteria; Antigen processing; Antigen presentation; bacteriology; Microbiology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. READ MORE
