2. 1. Shb and Its Homologues: Signaling in T Lymphocytes and Fibroblasts

   Author : Cecilia Lindholm; Hamid Band; Uppsala universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

   Abstract : 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.

4. 2. Consequences of Shb Deficiency on Hematopoietic Cell Function

   Author : Karin Gustafsson; Michael Welsh; Martin Bergö; Uppsala universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoiesis; hematopoietic stem cells; myeloid neoplasia; T cells; atopic dermatitis; cell signaling; Medical Cell Biology; Medicinsk cellbiologi;

   Abstract : The adaptor protein Shb has been implicated in the signaling of several tyrosine kinase receptors and previous studies have suggested a role for Shb in the signal transduction of T cells. Shb associates with the T cell receptor (TCR) and partakes in the signal propagation of activated T lymphocytes. READ MORE

5. 3. Decoding Heparan Sulfate

   Author : Johan Kreuger; John T. Gallager; Uppsala universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Heparan sulfate; fibroblast growth factor; receptor; endostatin; angiogenesis; interaction; sequence; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

   Abstract : Heparan sulfate (HS) is a polysaccharide of glycosaminoglycan type composed of alternating hexuronic acid [either glucuronic acid (GlcA) or iduronic acid (IdoA)] and glucosamine (GlcN) units that can be sulfated in various positions. HS binds to a large number of proteins and these interactions promote many biological processes, including cell adhesion and growth factor signaling. READ MORE

6. 4. T-Cell Protein Tyrosine Phosphatase, a Regulator of the PDGF Signaling Pathway

   Author : Susann Karlsson; Carina Hellberg; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; TC-PTP; receptor trafficking; PK-M2; Medical cell biology; Medicinsk cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

   Abstract : Platelet-derived growth factor (PDGF) is a potent stimulator of cell growth, survival and motility. PDGF exerts its function by binding to specific tyrosine kinase receptors, initiating receptor auotphosphorylation and initiation of specific signaling pathways that regulates the cellular response.

7. 5. Early events in T cell development

   Author : Karin Leandersson; Malmö Cancerimmunologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; pTalpha; gammadelta T cell; alphabeta T cell; development; thymus; thymocyte; serology; transplantation; Immunologi; serologi;

   Abstract : T cells constitute a heterogenous population of lymphocytes. Their unifying property is that they express surface bound antigen-receptors, called T cell receptors (TCRs). The TCR is a heterodimer composed of either TCRalpha and beta chain proteins (alphabeta TCR) or gamma and delta chain proteins (gammadelta TCR). READ MORE
