  1. 6. Studies on the transmembrane signaling of β1 integrins

    Författare :Annika Armulik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin β1; signaling; transmembrane domain; CAS; focal adhesion kinase; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Integrins are heterodimeric cell surface receptors, composed of an α and a β subunit, mainly binding for extracellular matrix proteins. lntegrin subunit β1 can combine with at least 12 a subunits and thus form the biggest subfamily within the integrin family. LÄS MER

  3. 7. Regulation of Hyaluronan Synthesis and Signaling via CD44 in Cancer

    Författare :Merima Mehić; Paraskevi Heldin; Carl-Henrik Heldin; Liliana Schaefer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyaluronan; CD44; TGFβ; PDGF-BB; cancer; signaling; hyaluronan synthase; epithelial-mesenchymal transition; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Hyaluronan is a ubiquitous glycosaminoglycan which is an important constituent of the extracellular matrix (ECM). In addition to organizing the extracellular matrix and regulating tissue homeostasis, hyaluronan, by binding to its main cell surface receptor CD44, is involved in intracellular signaling pathways regulating major cellular processes during development, wound healing, inflammation and cancer.

  4. 8. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

    Författare :Huamei Fu; Göteborgs universitet; []
    Nyckelord :neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

    Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER

  5. 9. Laminin G Domains, their Receptors, and Activation of Intracellular Pathways

    Författare :Hao Yu; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; cell-matrix interaction; signaling; receptor; Basement membrane; laminin;

    Sammanfattning : Basement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. LÄS MER

  7. 10. Analysis of PDGF receptor internalization and signaling using proximity ligation assays

    Författare :Marie Rubin Sander; Ola Söderberg; Cristina Al-Khalili Szigyarto; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
