  1. 11. Development of Capacitive Biosensors for Monitoring of Bacterial Toxins and Other Biomolecules

    Författare :Mahmoud Labib; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme-linked immunosorbent assay; self-assembled monolayers; competitive capacitive biosensing; cholera toxin; Capacitive biosensor; surface plasmon resonance; staphylococcal enterotoxin B; nanogold; human immunoglobulin G; glucose;

    Sammanfattning : Sensing and quantification of biomolecules are becoming increasingly important in medical diagnostics, bioprocess technology and recently in homeland security. The majority of techniques currently employed to interrogate biomolecules require some type of radio-, enzymatic- or fluorescent-labeling. LÄS MER

  4. 13. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

    Författare :Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

    Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER

  5. 14. Delivery of TypeIII Secreted Toxins by Yersinia pseudotuberculosis : the Role of LcrV, YopD, and Free Lipids in the Translocation Process

    Författare :Jan Olsson; Hans Wolf-Watz; Ina Attree; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yersinia; T3SS; translocation; YopD; LcrV; YLC; fatty acids.; Molecular biology; Molekylärbiologi;

    Sammanfattning : Bacteria that infect humans and animals face a hard combat with the host´s immune system and in order to establish infection, pathogenic bacteria has evolved mechanisms to avoid being cleared from the host tissue. Many Gram-negatives carry a Type 3 secretion (T3S) system that is used to deliver effector proteins (toxins) into host cells. LÄS MER

  7. 15. Bacterial physiology and its role in antibiotic refractoriness

    Författare :Spyridon Gkotzis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The pathological outcome of a bacterial infection depends on the interplay among the host’s innate defenses, the virulence arsenal of the pathogen and antibiotic treatment strategies. Understanding this interplay will provide mechanistic insights on antibiotic pharmacodynamics and bacterial pathogenesis, and set the stage for the development of novel therapeutic interventions.
