  1. 26. Rewiring ret : PTB-adaptor regulated signaling and cell biology

    Författare :T Kalle Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Ret receptor belongs to a group of transmembrane tyrosine kinase receptors that serve to transduce environmental signals into cellular responses. Upon extracellular ligand activation the receptors dimerize and their structural conformation is altered into one that allows for interaction with proteins in the cell cytosol. LÄS MER

  2. 27. Helicobacter pylori : multitalented adaptation of binding properties

    Författare :Sara Henriksson; Thomas Borén; Göran Larson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; adherence; receptor specificity; adaptation; pH; BabA; Leb; recombination; secretor phenotype; recombinant cell lines;

    Sammanfattning : Helicobacter pylori infects and persistently colonizes the stomach, which results in gastritis and in some individuals peptic ulcer disease or gastric cancer. Adherence of H. pylori to the epithelium is an important factor for development of disease. LÄS MER

  3. 28. Translational studies of molecular interactions in Parkinson’s disease

    Författare :Ellen Hertz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Interactions between molecules are the basis of cellular function. In disease, these tightly regulated systems are often disturbed. Parkinson’s disease (PD) is recognized by protein aggregates in the brain of erroneously interacting molecules, directly linking the clinical picture to the molecular mechanisms. LÄS MER

  4. 29. Studies of cell signalling using bacterial toxins and organic electronic devices

    Författare :Peter Kjäll; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One of the most versatile biological signalling entities is the calcium ion, Ca2+. With a characteristic spatial and temporal signalling pattern, this universal second-messenger directs diverse cellular functions, e.g. secretion of neurotransmitters at the synaptic cleft to regulation of transcription and fertilization.

  5. 30. Visualizing the dynamic interplay between the host and bacterial pathogen : a real-time study of renal infection

    Författare :Lisa Månsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human body is a complex entity capable of handling a variety of pathogenic challenges without developing disease symptoms. Sometimes, however, the pathogens are superior and the host immune system is unable to clear the infection. LÄS MER
