  1. 1. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation

    Författare :Marcus Wäneskog; Sanna Koskiniemi; Paul Rainey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial interactions; cell-cell binding; contact-dependent growth inhibition; CDI; CdiB; CdiA; CdiI; outer-membrane receptor; BamA; OmpC; OmpF; extracellular toxin delivery; Toxin-Antitoxin; TA-system; persister cells; stress tolerance; stress response; rpoS; rssB; quorum sensing; multicellular behavior; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. LÄS MER

  3. 2. Molecular characterization of the Drosophila responses towards nematodes

    Författare :Md. Badrul Arefin; Ulrich Theopold; Ioannis Eleftherianos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; nematodes; infection; danger situations; immune response; coagulation; apoptosis; nitric oxide; leukemia; Molecular Biology; molekylärbiologi;

    Sammanfattning : A sophisticated evolutionary conserved innate immune system has evolved in insects to fight pathogens and to restrict damage in harmful (danger) situations including cancer. A significant amount of knowledge about different infection models in Drosophila has been generated in past decades, which revealed functional resemblances and implications for vertebrate systems.

  4. 3. Clonal structures and cell interactions in cancer

    Författare :Nathanael Andrews; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Despite sharing an identical genome, cells of higher order multicellular organisms display a large degree of phenotypic diversity. This diversity is maintained by a sophisticated regulatory machinery that integrates information from both intrinsic and extrinsic factors, ultimately coordinating the appropriate gene expression.

  5. 4. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins

    Författare :Martin Lidman; Gerhard Gröbner; Magnus Wolf-Watz; Philip Williamson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bax; Bc-2; apoptosis; mitochondria; membranes; oxidized lipids; NMR; calorimetry; circular dichroism; biokemi; Biochemistry; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. LÄS MER

  7. 5. Cell-matrix interactions : master regulators of cancer cell fate?

    Författare :Sara Göransson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The development and homeostasis of a multicellular organism require fundamental biological processes like cell proliferation, cell differentiation, cell migration, and controlled cell death. The extracellular matrix (ECM) guides many of these functions, via cell-matrix interactions that function as mechanical and biochemical signaling hubs. LÄS MER
