1. Activity of tumor-antigens in polyomavirus replication
Sammanfattning : Polyomavirus replication needs an active cell environment, and the viral DNA replication is cell cycle regulated. Tumor antigens (T-antigens) of mouse polyomavirus, especially large T-antigen, are necessary for the replication. LÄS MER
2. Immunological aspects of papillary thyroid carcinoma
Sammanfattning : Papillary thyroid carcinoma (PTC) is a puzzling disease. Although approximately 70% of patients with PTC have regional lymph node metastases at initial surgery, the long term survival is over 95%. LÄS MER
3. Tumor recognition by cytotoxic T cells : definition of new tumor antigens and the effect of interleukin-10 on antigen presentation
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
4. The HER2/neu oncoprotein and dendritic cells in immunity against tumors
Sammanfattning : It is now well established that small peptide epitopes bound to the major histocompatibility complex (MHC), derived from processed proteins synthesized by the tumor cells, can be recognized as antigens by cytotoxic T lymphocytes (CTLs). A number of tumor antigens recognized by CTLs on human melanomas have been defined, but less is known about antigens from other tumor types. LÄS MER
5. Cancer therapy using viral and bacterial proteins as vectors for vaccines or as carriers of cytostatics
Sammanfattning : New cancer therapies are urgently needed, since available treatment options today have negative side effects, and cure only about half of the patients with invasive cancer. One, relatively new, option is to vaccinate against cancer, by introducing an antigen that is present on the tumor cells into the patient to stimulate specific immunity against the tumor. LÄS MER
