  1. 26. Epstein-Barr virus latency in transplant patients and healthy carriers

    Författare :Jie-Zhi Zou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis, I studied the latency situation of Epstein-Barr virus (EBV) in bone marrow transplanted (BMT) patients and healthy virus carriers. Paper 1: Epstein-Barr virus genomes are found predominantly in lgA-positive B cells in the blood of healthy carriers. LÄS MER

  3. 27. From Parasitoids to Gall Inducers and Inquilines : Morphological Evolution in Cynipoid Wasps

    Författare :Hege Vårdal; Fredrik Ronquist; Göran Sahlén; Ulf Jondelius; Nunzio Isidoro; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; gall inducer; parasitoid; inquiline; gall induction; morphology; Biologi; Biology; Biologi;

    Sammanfattning : One of the large lineages of parasitic wasps, the Cynipoidea, exhibits three distinctly different life modes. Slightly more than half of the about 3000 species are parasitoids in insect larvae, whereas the remaining species are associated with plants, either as gall inducers or as inquilines (guests feeding on plant tissue in galls).

  4. 28. Multipotent mesenchymal stromal cell transplantation : possible viral complications and alloimmunity

    Författare :Mikael Sundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mesenchymal stem cell; immunogenicity; viruses; transplantation; antibodies; GvHD;

    Sammanfattning : In the last few years, human multipotent mesenchymal stromal cells (MSC) have been increasingly used in novel therapeutic strategies due to their intrinsic immunosuppressive, anti-inflammatory and regenerative properties. In hematopoietic stem cell transplantation (HSCT), a curable treatment of hematological malignancies and several non-malignant conditions, MSC have been used as a therapy for graft-versus host-disease (GvHD) and other complications.

  5. 29. EBV membrane protein LMP2A interactions with ubiquitin ligases and a signaling scaffold

    Författare :Liudmila Matskova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Epstein-Barr virus EBV ; Latent membrane protein 2A LMP2A . HECTdomain E3 ubiquitin ligase; Shb signaling scaffold. Akt kinase; Tyrosine phosphorylation.;

    Sammanfattning : Over 90% of the adult human population carries Epstein-Barr Virus (EBV). EBV stays for life, striking a balance with the immune system. The virus evades immune elimination by severely restricting its own gene expression. The latent infection is established with the resting memory type B-cell as the reservoir. LÄS MER

  7. 30. TRANSMISSION AND PATHOGENESIS OF HANTAVIRUS

    Författare :Lisa Pettersson; Magnus Evander; Clas Ahlm; Annika Allard; Tatjana Avšič - Županc; Umeå universitet; []
    Nyckelord :Puumala virus; Hantavirus; human-to-human transmission; saliva; nephropathia epidemica; NE; IgA; IgG; IgM; neutrophils; neutrophil; viremia; treatment; climate; snow cover; temperature.; medicinsk virologi; Medical Virology;

    Sammanfattning : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. LÄS MER
