IL-6 Responsiveness of CD4+ and CD8+ T Cells after Allogeneic Stem Cell Transplantation Differs between Patients and Is Associated with Previous Acute Graft versus Host Disease and Pretransplant Antithymocyte Globulin Therapy
Tvedt, Tor Henrik Anderson; Rose-John, Stefan; Tsykunova, Galina; Ahmed, Aymen B; Gedde-Dahl, Tobias; Ersvær, Elisabeth; Bruserud, Øystein (Journal article; Peer reviewed, 2022)Graft-versus-host disease (GVHD), one of the most common and serious complications after allogeneic stem cell transplantation, is mediated by allocative T cells. IL-6 mediates both pro- and anti-inflammatory effects and ... -
Immunological aspects of acute myelogenous leukemia
Ersvær, Elisabeth (Doctoral thesis, 2007-02-23)Acute myelogenous leukemia (AML) is an aggressive malignancy characterized by accumulation of immature myeloid cells in the bone marrow. The overall disease-free survival is less than 50% even for the younger patients who ... -
The immunological dilemma: Cellular innate and adaptive immune response versus human acute myeloid leukemia
Ersvær, Elisabeth; Olsnes, Astrid M.; Bruserud, Øystein (Peer reviewed; Journal article, 2007)It is generally accepted that acute myelogenous leukemia (AML) patients are immunocompromized.
