2. 11. NK cell and dendritic cell interactions in innate immune responses

   Author : Catrine M Persson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : NK cells; Dendritic cells; crosstalk; recruitment; activation; CD94 NKG2AQa1; Toxoplasma gondii;

   Abstract : Natural killer (NK) cells are cytotoxic cells of the innate immune system. They have been found to be critical in the defense against infections and also against some tumors. Recent studies have shown that NK cells require signals from accessory cells to induce their recruitment and activation at the site of infection or tumor growth. READ MORE

4. 12. Processing and presentation of exogenous antigen by dendritic cells

   Author : Liying Chen; Karolinska Institutet; Karolinska Institutet; []
   Keywords : DC; vesicular MHC-I processing; Adenosine; CD 1 d; TACA;

   Abstract : Dendritic cells (DC) play a key role in the immune system. In this thesis, we have investigated and characterized pathways for the processing and presentation of exogenous OVA on MHC-I ("cross-presentation") and how these were influenced by the purine nucleoside Adenosine (Ado), an immune regulator that accumulates to high concentrations at sites of inflammation and tumor growth.

   Abstract : 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. READ MORE

   Abstract : Toxoplasma gondii is an obligate intracellular Apicomplexan parasite that could possibly infect all warm-blooded animals. Acute infections with T. READ MORE

7. 15. Tissue regulation of dendritic cells : with focus on chemokines, function and migration

   Author : Anh Thu Nguyen Hoang; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Tissue-specific cells, such as fibroblasts and epithelial cells in local microenvironments have been recognized to influence the function and phenotype of hematopoietic cells, such as dendritic cells (DC). The interaction and cooperation between DC and the cells of the tissue is important for the maintenance of immune homeostasis as well as orchestrating immune responses against pathogens. READ MORE
