   Sammanfattning : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. LÄS MER

3. 2. Protective Immunity in Atherosclerosis

   Författare :Maria Wigren; Kardiovaskulär forskning - immunitet och ateroskleros; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AtherosclerosisVaccineInflammationT cellsregulatory T cells;

   Sammanfattning : The immune system is a promising target for novel therapies that are aiming at reducing cardiovascular diseases. Autoimmune responses against modified low density lipoprotein (LDL) are believed to promote development of atherosclerosis. Proinflammatory immune responses can be counterbalanced by immunosuppressive regulatory T cells (Tregs). LÄS MER

4. 3. 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.

5. 4. Effect of IL-1beta secretion on lymphoid tissue and on antitumor immune responses

   Författare :Olle Björkdahl; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; Immunologi; transplantation; Immunology; serology;

   Sammanfattning : Interleukin (IL)-1beta is one of the most pleiotropic and potent cytokines, produced predominantly by activated monocytes and macrophages. IL-1 plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. In the present study, we developed a model for active IL-1beta secretion.

7. 5. Combined chemotherapy and immunotherapy against experimental malignant brain tumors

   Författare :Sara Fritzell; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cisplatin; Glioma; GM-CSF; IFN-gamma; IL-7; Immunotherapy; Intratumoral chemotherapy; Temozolomide;

   Sammanfattning : Glioblastoma multiforme (GBM) is the most common and aggressive primary malignant brain tumor in adults. Despite standard treatment including surgery, radiotherapy and temozolomide (TMZ)-based chemotherapy, the prognosis for GBM patients is dismal, and there is a need for novel treatments. LÄS MER
