1. 6. Tumor-targeted superantigens for experimental immunotherapy of human leukemia/lymphoma

   Författare :Cecilia Weigelt; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; SAg; SEA; SEAm; HLA class II; TCR; CFL; SDCC; cytotoxicity; TNF a; IFN g; mAb; PA-SEAm; anti-CD19-Fab-SEAm; B-CLL; B-NHL; AML; CML; immunotherapy; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

   Sammanfattning : Bacterial superantigens (SAgs) have the property of stimulating high proportions of T cells expressing certain TCR Vβ sequences. The SAg first binds with high affinity to HLA class II molecules on the target cell and then stimulates the T cell to produce cytokines and to become cytotoxic. LÄS MER

3. 7. The Myc network of growth regulators and its interplay with growth and differentiation signals

   Författare :Siqin Wu; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Myc; Mad1; p21Cip1; phorbol ester; IFN-g; TGF-b; differentiation; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   Sammanfattning : The proto-oncogenes/tumor suppressor genes of the Myc/N4ax/Mad network encode transcription factors that are important regulators of cell growth, differentiation, and apoptosis and that are frequently implicated in tumor development. Regulation of their biological functions by growth/differentiation signals as well as their interplay with growth/differentiation signalling pathways play important roles in cell fate determination.

4. 8. Immuno Gene Therapy of Rat Brain Tumors with interferon-gamma transfected glioma cells

   Författare :Edward Visse; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; transplantation; serologi; Immunologi; Immunotherapy; Rat brain tumor; Interferon-gamma; isograft rejection; tumor infiltrating lymphocytes; Immunization; Immunology; serology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : Immunotherapy is a new promising approach in cancer treatment. In the future, it will hopefully offer an alternative to existing brain tumors treatments, which are unable to cure. We have established an experimental, low immunogenic, brain tumor model in the rat. LÄS MER

5. 9. NO, Immunosuppression and Tumor Immmunotherapy

   Författare :Pontus Hegardt; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; IL-18; IFN-gamma; rat; colon carcinoma; glioma; tumor immunotherapy; immunosuppression; NO; iNOS;

   Sammanfattning : This study aims at clarifying the role of NO in the immunosuppression induced by in vivo tumor growth and by tumor immunotherapy, and determining whether the inhibition of NO production can be used as an adjuvant in tumor immunotherapy. We have shown previously that tumor cells, glioma (N32) and colon carcinoma (H1D2), when genetically engineered to express such immune stimulatory cytokines as IFN-g and IL-18, induce strong anti-tumor immune response, in immunized tumor-free rats, whereas only a limited therapeutic effect is achieved in rats in which a tumor has already become established.

7. 10. Innate and acquired immunity to commensal bacteria

   Författare :Christina Hessle; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The innate immune system recognises molecular patterns shared by large groups of micro-organisms. Monocytes and macrophages respond to microbes by production of substances which act in concert to promote effective clearance of bacteria. LÄS MER
