  1. 1. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    Författare :Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

    Sammanfattning : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. LÄS MER

  3. 2. T cell and antibody responses in Plasmodium falciparum malaria and their relation to disease susceptibility

    Författare :Salah Eldin Farouk; Marita Troye-Blomberg; Hannah Akuffo; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P. falciparum; Malaria; Granulysin; Fulani; Schizont; Immunology; Immunologi;

    Sammanfattning : Malaria antigen-induced polarization of T cells into effectors Th1 and/or Th2 cells and their subsequent release of cytokines is known to affect antibody production. This thesis includes studies on early innate responses to the parasite, with a focus on γδT cells, and acquired specific responses in African sympatric ethnic tribes. LÄS MER

  4. 3. Defining human adaptive immune gene diversity

    Författare :Sanjana Narang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The lymphocytes (B and T cells) of the adaptive immune system undergo variable (V), diversity (D), and junctional (J) gene recombination, resulting in highly diverse antigen receptor repertoires capable of recognizing a wide variety of invading pathogens. The B cell receptor (BCR) contains two identical heavy and light chains. LÄS MER
