  2. 1. Structures, toxicity and internalization of cell-penetrating peptides

    Author : Emelía Eiríksdóttir; Ülo Langel; Michael Gait; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; cell-penetrating peptide; internalization; toxicity; structures; Neurochemistry; Neurokemi; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. READ MORE

  4. 2. Analysis of PDGF receptor internalization and signaling using proximity ligation assays

    Author : Marie Rubin Sander; Ola Söderberg; Cristina Al-Khalili Szigyarto; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGFRβ; dynamin; proteolytic cleavage; signaling; internalization; protein-protein interaction; short linear motif; viral hijack; in situ PLA; Molboolean;

    Abstract : Cell signaling is mediated by signaling proteins that relay the signal in an intricate network of interactions before the signal is translated into a biological response. Short linear motifs (SLiMs) in intrinsically disordered regions of proteins serve as docking sites for protein interaction in all aspects of cell regulation including signal transduction. READ MORE

  5. 3. The Internalization of External Effects in Swedish Transport Policy - A Comparison Between Road and Rail Traffic

    Author : Lars Hansson; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commercial and industrial economics; rail traffic; road traffic; transport policy; internalization; External effects; pricing-relevant costs; Industriell ekonomi;

    Abstract : Transport is a key factor for economic growth. It has enabled both the economic scale of production and an increase in competition. No one can question this role of transportation. There is, however, a back-side to the coin: the environmental challenge. READ MORE

  6. 4. REGULATED UPTAKE OF BIOPOLYMERS Role of cell surface proteoglycans Implications for drug and gene delivery

    Author : Staffan Sandgren; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Cytology; oncology; proliferation; differentiation; Medicine human and vertebrates ; growth factor; cancer; drug delivery; gene therapy; LL-37; HIV-Tat; cell penetrating peptides; polyamines; heparan sulfate; onkologi; Cytologi; cancerology; internalization; proteoglycans;

    Abstract : Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes.

  7. 5. Novel Methods for Analysis of Heterogeneous Protein-Cell Interactions : Resolving How the Epidermal Growth Factor Binds to Its Receptor

    Author : Hanna Björkelund; Karl Andersson; Lars Gedda; Yosef Yarden; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heterogeneity; Kinetics; EGFR; HER2; LigandTracer; Interaction Map; Internalization; Specificity; Medical Science; Medicinsk vetenskap;

    Abstract : Cells are complex biological units with advanced signalling systems, a dynamic capacity to adapt to its environment, and the ability to divide and grow. In fact, they are of such high level of complexity that it has deemed extremely difficult or even impossible to completely understand cells as complete units. READ MORE
