3. 2. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

   Författare :Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

   Sammanfattning : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. LÄS MER

4. 3. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells

   Författare :Anna Lundgren; Göteborgs universitet; []
   Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; T cells; regulatory T cells; dendritic cells; T-cell recruitment;

   Sammanfattning : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

5. 4. On CD4+ T Lymphocytes in Solid Tumours

   Författare :Per Marits; Ola Winqvist; Magnus Thörn; Alex Karlsson-Parra; Uppsala universitet; []
   Nyckelord :Molecular medicine; Tumour immunology; T lymphocytes; sentinel node detection; colon cancer; urinary bladder cancer; adoptive immunotherapy; Molekylärmedicin;

   Sammanfattning : This thesis deals with recognition and elimination of tumours by T lymphocytes and their use in adoptive immunotherapy.The first tumour-draining lymph node; the sentinel node, is identified by peritumoural injection of a tracer. This is the hypothesised location for the activation of tumour-reactive lymphocytes. LÄS MER

7. 5. Recognition requirements and regulatory events directing T cell responses

   Författare :Martin Gullberg; Eva-Lotta Larsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cell growth factor production; Lyt-2-positive T suppressor cell; Lyt-2-positive cytotoxic T lymphocytes; activation requirements of T lymphocytes; blocking of T cell functions;

   Sammanfattning : The present study has considered cellular and molecular requirements in T cell responses. The central role of T cell growth factors (TCGF) in T cell responses prompted us to study the regulatory events directing TCGF production in lectin stimulated cultures. LÄS MER
