  1. 16. CD8+ T cell specificity in thymic selection and in the recognition of antigen

    Författare :Johan Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :T cell; specificity; MHC class 1; selection; tolerance;

    Sammanfattning : Specificity mediated by the T cell receptor (TCR) is of fundamental importance for the ability of T cells to function, and regulate humoral immunity and effector mechanisms of the innate immune system. T cells recognize composite molecules consisting of products of the major histocompatibility complex (MHC) class I or class 11 loci, in complex with a short peptide fragment derived from endogenous or antigenic proteins.

  2. 17. Evaluating antitumoral lymphocytes for adoptive cell therapy : oxidative stress, neoantigen processing and co-stimulation

    Författare :Stefanie Marie Renken; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Rapid advancement in the field of immunotherapy has changed the treatment landscape of cancer, especially with the approval of immune checkpoint inhibitors for a wide range of cancer types. However, a large proportion of patients does not benefit from this treatment. LÄS MER

  3. 18. A New Look into Protein C Inhibitor : Posttranslational Modifications and their Functions

    Författare :Wei Sun; Sophia Schedin Weiss; Hakon Leffler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Protein C inhibitor; posttranslational modifications; N-glycan; O-glycan; mass spectrometry; factor Xa; thrombin; prostate specific antigen; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : The influences of posttranslational modifications on the functions of the versatile serpin protein C inhibitor (PCI) were studied. PCI is a serine protease inhibitor that is expressed in many tissues and secreted to various fluids in human, including blood plasma, seminal plasma, and urine. LÄS MER

  4. 19. Cancer imaging and image analysis methods in whole-body MRI and PET/MRI

    Författare :Therese Sjöholm; Joel Kullberg; Filip Malmberg; Robin Strand; Håkan Ahlström; Einar Heiberg Brandt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; diffusion weighted imaging; positron emission tomography; whole-body imaging; normal atlas; CAR T-cell therapy; lymphoma; medical image analysis; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Diagnostic medical imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) can provide structural and functional assessments of the whole body. This has great value for potentially systemic diseases such as cancer. LÄS MER

  5. 20. The interactome of the Epstein-Barr virus nuclear antigen 5 suggests novel roles in RNA and protein metabolism

    Författare :Josefine Ekholm; Göteborgs universitet; []
    Nyckelord :Epstein-Barr virus; EBNA5; chaperone; proteasome; nucleolus;

    Sammanfattning : Epstein-Barr virus (EBV) is a human herpes virus that infects B and epithelial cells of the oropharynx. EBV is transmitted by saliva and establishes a lifelong latency in over 90% of the world's population. During latency, the virus exists predominantly as multicopy episomes in the nuclei of memory B cells. LÄS MER
