1. 21. 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.

3. 22. Immunologic Markers in the Tumor Microenvironment of Classical Hodgkin Lymphoma

   Författare :Alex R. Gholiha; Gunilla Enblad; Rose-Marie Amini; Peter Hollander; Gustaf Hedström; Arjan Diepstra; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tumor microenvironment; immunohistochemistry; immune checkpoints; Plasma cells; IL-6 cytokine; Proteomics; CD47.;

   Sammanfattning : In classical Hodgkin lymphoma (cHL), cytokine regulation and cellular composition of the tumor microenvironment (TME) is crucial for tumor cell survival. In paper I, we examined the presence of CD138+ plasma cells and IgG4+ plasma cells in diagnostic cHL biopsies with immunohistochemistry (IHC). LÄS MER

4. 23. Regulatory T cells and mucosal-associated invariant T cells in colon adenocarcinomas; Phenotype and function

   Författare :Filip Ahlmanner; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colon cancer; regulatory T cells; CD39; adenosine; immune checkpoint molecules; immunosuppression; MAIT cells; cytokines; cancer-specific survival;

   Sammanfattning : In many solid cancers, and also in colon adenocarcinomas, an increased accumulation of lymphocytes is beneficial for the patient. However, tumor-infiltrating immune cells may be either pro- or anti-tumorigenic and the balance between these two counteracting forces partly determines patient outcome. LÄS MER

5. 24. 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

7. 25. Tumor instructed normal tissue : studies of potential extratumoral biomarkers and therapeutic targets in prostate cancer

   Författare :Maria Nilsson; Sofia Halin Bergström; Anders Bergh; Kristian Pietras; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; biomarkers; tumor-instructed normal tissue; extra cellular matrix; macrophages; LOX; HO-1; MSMB; Pathology; patologi;

   Sammanfattning : Prostate cancer is the most common cancer in men in Sweden and but luckily the majority of the patients will carry on their life without any consequences from the disease. Unfortunately, some will develop aggressive tumors and eventually die. LÄS MER
