  2. 1. Immune dysregulation in HIV-1 infected lymphoid tissue

    Author : Homira Behbahani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1; HAART; cytokines; chemokines; lymphoid tissue; perforin; Nef; LIF; placenta; chemokine receptor;

    Abstract : Lymphoid compartments are major sites for HIV-1 replication. We evaluated cytokines, chemokines and immunological effector function at the single cell level in lymphoid tissues in chronically HIV-1 infected patients. READ MORE

  4. 2. Tertiary lymphoid structures in glioblastoma : Discovery, Characterization and Therapeutic Induction

    Author : Alessandra Vaccaro; Anna Dimberg; Victor Engelhard; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tertiary lymphoid structures; Glioma; Glioblastoma; Immunotherapy; Immunologi; Immunology; Oncology; Onkologi;

    Abstract : Glioblastoma (GBM) is an incurable brain cancer with a median survival of less than two years from diagnosis. The tumor microenvironment plays a major role in GBM progression through sustaining immunosuppression and poor lymphocytic infiltration. READ MORE

  5. 3. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Author : Lucia Mincheva-Nilsson; Sten Hammarström; Rolf Kiessling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Abstract : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. READ MORE

  6. 4. Evolution of HIV-1 coreceptor use in relation to pathogenesis

    Author : Ingrid Karlsson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; RANTES; higly active antiretroviral therapy; pathogenesis; lymphoid tissue; cehmokine receptor; biological phenotype; coreceptor; HIV-1; evolution;

    Abstract : HIV-1 uses the coreceptors CCR5 and/or CXCR4 in addition to CD4 to enter the host cell. CCR5-using HIV-1 (R5 phenotype) appears to transmit infection and usually dominates the early stages of disease. READ MORE

  7. 5. Effect of IL-1beta secretion on lymphoid tissue and on antitumor immune responses

    Author : Olle Björkdahl; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; Immunologi; transplantation; Immunology; serology;

    Abstract : Interleukin (IL)-1beta is one of the most pleiotropic and potent cytokines, produced predominantly by activated monocytes and macrophages. IL-1 plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. In the present study, we developed a model for active IL-1beta secretion.
