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

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

    Abstract : 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. READ MORE

  4. 2. Vγ9Vδ2 T cells - response to P. falciparum-derived phosphoantigens and potential for use in colon cancer immunotherapy 

    Author : Chenxiao Liu; Ingela Parmryd; Susanna Cardell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Vγ9Vδ2 T cell is the dominant circulating γδ T cell subset in humans, can expand massively upon malaria infection and are cytotoxic to cancer cells. Vγ9Vδ2 T cells are stimulated by phosphoantigens, primarily isoprenoid pyrophosphates like isopentenyl pyrophosphate and (E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMBPP). READ MORE

  5. 3. Antibody responses in Plasmodium falciparum malaria and their relation to protection against the disease

    Author : Ahmed Kamal Bolad; Klavs Berzins; Lars Hviid; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunity; parasital immunology; Plasmodium falciparum malaria; antibody mediated invasion growth inhibition; Immunology; Immunologi;

    Abstract : Protective immunity against Plasmodium falciparum may be obtained after repeated exposure to infection. Several studies indicate that immunity against the blood stages of the P. Falciparum infection is mainly antibody mediated. READ MORE

  6. 4. Variable surface molecules of the plasmodium falciparum infected erythrocyte and merozoite

    Author : Malin Haeggström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : P.falciparum; infected erythrocytes; transport; Maurer s clefts; antigenic variation; PfEMP1; RIFIN; SURFIN; merozoites; subgroups;

    Abstract : As Plasmodium falciparum parasites matures within the infected erythrocyte (IE) it produces a number of various proteins, which are transported out to the cell surface where they are exposed to the host immune system. To avoid recognition and elimination by the liver and spleen these proteins can undergo antigenic variation, a phenomenon where the parasites switch from expressing one variant to' another, both belonging to the same gene-family.

  7. 5. Surface antigens in Plasmodium falciparum malaria : PfEMP1 and SURFIN4.2

    Author : Maria del Pilar Quintana Varon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Plasmodium falciparum malaria is an infectious disease that on despite of the ongoing eradication efforts is still endemic in more than 100 countries, sometimes causing severe disease that leads to the death of around half a million people per year. Malaria pathology is tightly associated with the parasite cycle inside the human red blood cells (RBCs). READ MORE
