  2. 1. Clinical applications of acoustophoresis in blood based diagnostics

    Author : Klara Petersson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Acoustofluidics; Ultrasound; Microfluidics; Blood; Blood Separation; Blood plasma; Lab-on-a-chip; Point-of-care; Blood diagnostics;

    Abstract : In this thesis, acoustofluidics has been used to process blood samples as a sample preparation step prior to biomarker detection. This is often required as the large amount of blood cells otherwise can interfere with the detection method. Acoustofluidics means moving particles or cells with acoustic forces within microfluidic channels. READ MORE

  4. 2. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Author : Josef Azem; Göteborgs universitet; []
    Keywords : Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Abstract : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. READ MORE

  5. 3. Acoustofluidic preparation of whole blood components

    Author : Anke Urbansky; NanoLund: Centre for Nanoscience; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; acoustophoresis; ultrasound; microfluidics; cell separation; blood; blood fractionation;

    Abstract : Whole blood is rich in information about the physical state of an individual and is routinely used in a variety of clinical and research applications. In this thesis, the use of a microfluidic technique called acoustophoresis for separation of different blood components is explored. READ MORE

  6. 4. Dendritic cells in cancer immunotherapy

    Author : Karin Gustafsson; Göteborgs universitet; []
    Keywords : vaccines; dendritic cells; αDC1; PGE2DC; natural killer cells; T cells;

    Abstract : Dendritic cells (DCs) play a central role in the initiation and regulation of innate and adaptive immune responses and have increasingly been applied as vaccines for cancer patients. Ex vivo generation and antigen loading of monocyte-derived DCs allows a controlled maturation, with the aim of imprinting different DC functions that are essential for their subsequent induction of a T cell-mediated anti-tumor response.

  7. 5. Mucosal dendritic cells in inflammatory bowel disease

    Author : Sa'ad Yislam Salim; Johan D. Söderholm; Mary jo Wick; Linköpings universitet; []
    Keywords : Blood; Crohn s disease; dendritic cells; E. coli; FACS; follicle-associated; epithelium; human; ileum; mixed lymphocyte reaction; permeability; Peyer s patches; SAMP1 YitFc; Ussing chambers; villous epithelium; MEDICINE; MEDICIN;

    Abstract : Crohn's disease, a chronic inflammation of the bowel, is a multi-factorial condition where uncontrolled immune responses to luminal bacteria occur in genetically predisposed individuals. The first observable clinical signs are small ulcers that form at a specialised form of epithelium, follicle-associated epithelium (FAB). READ MORE
