1. 16. Roadmap for teleoperation and automation of forwarding

   Författare :Mikael Lundbäck; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Annually, about two billion m3 of industrial roundwood is harvested worldwide. For a mature forest industry like the Swedish, the next technological development leaps regarding harvest operations are likely to involve increased level of tele-operation and automation. LÄS MER

3. 17. 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

4. 18. Regulation of T cell activation and death by the affinity of TCR for peptide/MHC complexes

   Författare :Cheng-Hong Wei; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The aim of this study is to investigate the role of the affinity of peptide:MHC/TCR interaction in the regulation of T cell activation, death and repertoire selection. Three aspects pertinent for our understanding of this issue have been analyzed. LÄS MER

5. 19. Immunoregulation by mononuclear phagocytes. Mechanisms and clinical implications

   Författare :Ana Romero; Göteborgs universitet; []
   Nyckelord :;

   Sammanfattning : The cytotoxic effector lymphocytes of the immune system, the natural killer (NK) cells and the CD8+ T lymphocytes (CTL), have been ascribed a pivotal role in defense against malignancy. However, the function of these cells is frequently compromised, in particular at sites of malignant cell expansion. LÄS MER

7. 20. Tumor recognition by cytotoxic T cells : definition of new tumor antigens and the effect of interleukin-10 on antigen presentation

   Författare :Flavio Salazar-Onfray; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The tumor antigens against which T cell responses have been demonstrated most frequently are not tumor specific but are also expressed on normal tissues. This observation has been interpreted as evidence for breaking of immunological tolerance to normal cellular proteins. LÄS MER
