  1. 1. Cytokine capture with beads in cytotoxicity assays in microwells

    University essay from KTH/Tillämpad fysik

    Author : Maxime Simon; [2023]
    Keywords : Microbead; Inteferon gamma; Natural Killer cells; microwell; binding-reaction model; Mikrokula; Interferon gamma; Naturliga Mördarceller; Mikrobrunn; modell för bindningsreaktion;

    Abstract : Cytokines are small, secreted proteins that are important for cell signalling in theimmune system. Interferon gamma (IFN-γ) is one of the most potent cytokines thatnatural killer (NK) cells of the innate immune system secrete with both antiviral,antibacterial, and antitumoral activity. READ MORE

  3. 2. Single-molecule Imaging of the Cell Division Ring in Escherichia coli Using the ALFA-tag

    University essay from KTH/Tillämpad fysik

    Author : Emma Westlund; [2023]
    Keywords : ALFA-tag; Escherichia coli; Divisome protein FtsZ; mEos3.2; Nanobodies; Nanotags; PALM; Plasmid transformation; sfGFP; Single-molecule Imaging; ALFA-tag; Escherichia coli; Divisomprotein FtsZ; mEos3.2; Nanokroppar; Nanotaggar; PALM; Plasmidtransformation; sfGFP; Enmolekyl-mikroskopi;

    Abstract : The use of super-resolution (SR) microscopy is an important tool for understanding the inside mechanisms of bacterial cells. However, for SR imaging, the labelling of the proteins of interest is a great challenge as flourescent proteins (FPs) are often too big to be directly fused to the target protein and traditional immunolabelling with antibodies creates too long separation between the fluorophore and the target protein.

  4. 3. Feedback imaging of cellular dynamics with fluorescence microscopy

    University essay from KTH/Tillämpad fysik

    Author : Emil Sorcini; [2022]
    Keywords : Tracking; Segmentation; Fluorescence microscopy; Lattice light-sheet; Cell migration; NK cells; ZEN; OAD; Experiment Feedback; Spårning; Segmentering; Fluorescensmikroskopi; Lattice light-sheet; Cellmigration; NK celler; ZEN; OAD; Experiment Feedback;

    Abstract : In biology, it is common to study cultured cells (in vitro) with fluorescence time-lapse microscopy. The cells are recorded for longer period of time and can later be viewed at an accelerated speed. During the acquisition some live cells tend to migrate. READ MORE

  5. 4. Structural features underlying antigen presentation by the non-classical MHC class Ib molecule Qa-1b

    University essay from KTH/Proteinvetenskap

    Author : Lejla AI-Tamimi; [2022]
    Keywords : immune checkpoint; NKG2A; MHC class Ib; Qdm; antibody; crystal structure;

    Abstract : Blockering av NKG2A receptorn på NK - och CD8+ T celler med en anti-NKG2A antikropp, medför en aktivering av cytolytisk aktivitet, och är en lovande immunkontrollpunkt i immunterapi mot cancer. Nyligen har en TCR-liknande antikropp, EXX1, som binder till liganden för NKG2A receptorn, Qa-1b - en icke-klassisk MHC klass Ib molekyl i möss -studerats i tumör modeller in vitro. READ MORE

  6. 5. Canine transmissible venereal tumour

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Oskar Eriksson; [2017]
    Keywords : CTVT; smittsam könstumör; hund; tumör;

    Abstract : Canine Transmissible Venereal Tumour (CTVT) är en unik smittsam tumörsjukdom. Likt en parasit är den naturligt överförbar mellan individer inom familjen Canidae via transplantation av levande tumörceller, framför allt genom parning. READ MORE
