1. 11. Molecular and Cellular Complexity of Glioma : Highlights on the Double-Edged-Sword of Infiltration Versus Proliferation and the Involvement of T Cells

   Författare :Demet Çağlayan; Bengt Westermark; Maria Ferletta; Ana Martin-Villalba; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioma; Sox2; Sox21; Snail; Bone morphogenetic protein; Sleeping Beauty; Gliomatosis Cerebri; T lymphocytes; T regulatory lymphocytes; Oncology; Onkologi; Biology; Biologi;

   Sammanfattning : Glioblastoma multiforme (GBM), the most common and malignant brain tumor, is characterized by high molecular and cellular heterogeneity within and among tumors. Parameters such as invasive growth, infiltration of immune cells and endothelial proliferation contribute in a systemic manner to maintain the malignancy. LÄS MER

3. 12. Recognition requirements and regulatory events directing T cell responses

   Författare :Martin Gullberg; Eva-Lotta Larsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cell growth factor production; Lyt-2-positive T suppressor cell; Lyt-2-positive cytotoxic T lymphocytes; activation requirements of T lymphocytes; blocking of T cell functions;

   Sammanfattning : The present study has considered cellular and molecular requirements in T cell responses. The central role of T cell growth factors (TCGF) in T cell responses prompted us to study the regulatory events directing TCGF production in lectin stimulated cultures. LÄS MER

4. 13. Shb and Its Homologues: Signaling in T Lymphocytes and Fibroblasts

   Författare :Cecilia Lindholm; Hamid Band; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Shb; T cell receptor; IL-2 receptor; PDGF receptor; cell signaling; adapter proteins; LAT; Vav; PLC-g1; SLP-76; JAK1; JAK3; Jurkat cells; T cells; NK cells; Apoptosis.; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Stimulation of the T cell receptor (TCR) induces tyrosine phosphorylation of numerous intracellular proteins, leading to activation of the interleukin-2 (IL-2) gene in T lymphocytes. Shb is a ubiquitously expressed adapter protein, with the ability to associate with the T cell receptor and several signaling proteins in T cells, including: the TCR ζ-chain, LAT, PLC-γ1, Vav, SLP-76 and Gads.

5. 14. Human T-lymphocyte activation : interactions between lymphocytes and mitogenic or non-mitogenic lectins

   Författare :Marie-Louise Dillner-Centerlind; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The aim of this investigation was to gain further insights in the mechanisms of T-lymphocyte activation by lectins. Interactions between the lectins and purified lymphocytes from human peripheral blood, were studied in the following respects: in vitro culture requirements for lectin induced DNA-synthesis, intercellular regulations of the mitogen response and binding of lectins to lymphocyte surface components.
