1. 1. Bioactive leishmanicidal alkaloid molecules from Galipea longiflora Krause with immunomodulatory activity

   Författare :Jacqueline Calla-Magariños; Carmen Fernández; Marita Troye-Blomberg; Geneviève Milon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Leishmania infection; Leishmaniasis; herbal medicine; natural products; Galipea longiflora Krause; Evanta; cytokines; IFN-gamma; dendritic cells; inflammation; meglumine antimoniate; immunologi; Immunology;

   Sammanfattning : According to WHO, leishmaniasis is endemic in 98 countries, and has been placed ninth in a global analysis of infectious diseases. Treatment of leishmaniasis is based on pentavalent antimonials but toxicity and developing resistance have been reported. LÄS MER

3. 2. Antibacterial peptides - key players in host defense at epithelial surfaces

   Författare :Mette Eliasson; allergologi och palliativ medicin Lungmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosa; epithelium; pharyngitis; Innate immunity; Streptococcus pyogenes; antibacterial peptides; IFN-gamma; CXCL9 MIG; chemokines;

   Sammanfattning : Innate host defense mechanisms at epithelial surfaces are important to prevent bacterial invasion. Streptococcus pyogenes, group A streptococcus (GAS), has an affinity for epithelial cells and cause pharyngitis. During streptococcal pharyngitis, high concentrations of the chemokines CXCL9/MIG, CXCL10/IP-10, CXCL11/I-TAC were found in tonsil fluid. LÄS MER

4. 3. 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

5. 4. Coeliac disease : Clinical and immunological aspects

   Författare :Tony Hansson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Coeliac disease; cytokines; TGF-beta; tissue transglutaminase; IL-4; IFN-gamma; TNF-alpha; ELISPOT; anti-endomysiumantibodies; anti-gliadin antibodies; Onkologi; Oncology; Onkologi; Klinisk immunologi; Clinical Immunology;

   Sammanfattning : A better immunological definition of coeliac disease and highly discriminatory serum markers are needed to identify children with early mucosal lesions and for rapid follow-up and a better knowledge of antigen reactivity and cytokine production will be needed to clarify the pathogenic mechanisms.The numbers of circulating IgAanti-gliadin antibody-producing (IgAAGA SFC) cells were increased in patients with untreated coeliac disease compared to controls and treated coeliac disease patients.

7. 5. 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.
