  1. 16. The activation and regulation of plasmacytoid dendritic cells in SLE : and possible therapeutic interventions

    Författare :Karin Hjorton; Lars Rönnblom; Maija-Leena Eloranta; Hans Carlsten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SLE; pDCs; NK cells; interferon; autoantibodies; immune complex; hydroxychloroquine; IRAK4 inhibition;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is an autoimmune disease, characterized by the presence of anti-nuclear antibodies and the formation of nucleic acid containing immune complexes (ICs), which can cause organ damage by deposition in tissues. ICs strongly trigger the plasmacytoid dendritic cells (pDCs) to produce interferon (IFN)-α, which potently activates the immune system. LÄS MER

  3. 17. Effects of Complement Opsonization of HIV on Dendritic Cells : and Implications for the Immune Response

    Författare :Rada Ellegård; Marie Larsson; Jorma Hinkula; Johan D Söderholm; William Paxton; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HIV; dendritic cells; complement; innate immune response; TLR signaling; T cell activation; NK cells; inflammation; antiviral response; immune evasion;

    Sammanfattning : Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells.

  4. 18. Microbial and maternal influences on allergic sensitization during childhood: defining a role for monocytes

    Författare :Shanie Saghafian Hedengren; Eva Sverremark-Ekström; Susan Prescott; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Monocytes; allergic sensitization; maternal allergy; Toll-like receptor; p38-MAPK; IL-6; Epstein-Barr virus; early-life microbial exposure; NK cells; IFN-γ; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : Allergic diseases are influenced by genetics and the environment. Maternal allergy appears to confer a higher risk for allergic sensitization than paternal allergy, suggesting an in utero influence. LÄS MER

  5. 19. Innate and acquired immunity to herpes simplex virus type 2 glycoprotein G in humans

    Författare :Lars Bellner; Göteborgs universitet; []
    Nyckelord :herpes simplex virus type 2; glycoprotein G-2; T-cell proliferation; Th1 cytokines; phagocytes; NK cells; reactive oxygen species; formyl peptide receptors;

    Sammanfattning : Herpes simplex virus type 2 (HSV-2) is a sexually transmitted pathogen that infects the human genital tract mucosa and is the most common cause of genital ulcer disease in humans. The infection exhibits a broad clinical spectrum, ranging from severe recurrent episodes of genital herpes to being completely asymptomatic. LÄS MER

  7. 20. Targeting NOX2 in cancer

    Författare :Ebru Aydin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; reactive oxygen species; immunotherapy; nox2; nk cells; melanoma; histamine; metastasis; leukemia; aml; cml; kras; mpd;

    Sammanfattning : Reactive oxygen species (ROS) are short-lived, toxic derivatives of oxygen that are produced during mitochondrial respiration and by NADPH oxidases (NOX). By enzymatically generating ROS, the myeloid cell NOX2 plays a critical role in defense against bacteria and other microorganisms. LÄS MER
