  1. 1. Transforming Growth Factor-b, Regulatory functions on normal lymphocytes and tumor outgrowth Regulatory functions on normal lymphocytes and tumor outgrowth

    Författare :Åsa Schiött; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-b; monocyte; rat; costimulation; Th2; ERK; tumor; TIL; Immunology; serology; Immunologi; transplantation; T-lymphocyte; serologi;

    Sammanfattning : Transforming growth factor-beta (TGF-b) is a well-characterised growth regulatory factor, which acts on most cell types. This thesis has focused on the regulatory roles of TGF-b on normal lymphocytes. One interesting finding is that TGF-b acts both costimulatory and inhibitory on T-lymphocytes. LÄS MER

  3. 2. Ischemic Tolerance and Cell Signaling in the Rat Brain

    Författare :Mehrdad Shamloo; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preconditioning; cell death; tyrosine phosphorylation; tolerance; ERK; Calpain; CaMKII; PKC; protection; Brain; ischemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : A brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. LÄS MER

  4. 3. The mechanism of integrin inactivation and cell signalling induced by c-erbB2, an oncogenic growth factor receptor

    Författare :Shahram Hedjazifar; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c-erbB2; integrin á2â1; cell-matrix; integrin conformation; PKB; ERK; Rho; ILK; Nck-2;

    Sammanfattning : Overexpression of the oncogenic growth factor receptor, c-erbB2, is linked with poor prognosis in breast carcinomas and is used as a target for therapeutic strategies. To elucidate the mechanism underlying the tumorigenic action of an elevated c-erbB2 level, leading to homodimerization and activation, we have used an inducible system where a hybrid receptor consisting of the cytoplasmic and transmembrane domains of c-erbB2 fused to the extracellular domain of the trkA NGF receptor has been stably transfected into an immortalized mammary epithelial cell line.

  5. 4. Impact of Interleukin-6 family cytokine signalling on human endothelial cells and platelets

    Författare :Madelene Lindkvist; Magnus Grenegård; Liza Ljungberg; Alistair W. Poole; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gp130 signalling cytokines; inflammation; transsignalling; JAK STAT; MEK ERK; PI3K AKT; platelet aggregation; vasodilation;

    Sammanfattning : Endothelial cells lining the luminal side of blood vessels creates a barrier between the circulating blood and the extracellular matrix. Endothelial cells have important functions in regulation of vessel tension and inflammation. LÄS MER
